What is a cellular polycarbonate. What it is - polycarbonate, its advantages and disadvantages. Moisture resistance

In industrial and private construction, polymer products began to apply in the 70s of the past century. Halfway practice proved and actually confirmed the numerous advantages of using synthetic products. However, are not still familiar with its weight priorities.

Moreover, there are people who do not imagine that such a polycarbonate, which technical characteristics and technological advantages, it attracts builders, as in structures and structures it works at all, not new, but not all still known material.

To get full-fledged answers to the questions you are interested in, it is worth dealing with the specifics of the polymer product and the peculiarities of its production.

The popularity and demand of polycarbonate in construction is substantiated by a number of priority qualities characteristic of polymeric materials. Its extraordinary ease is combined with sufficiently high strength and resistance to a number of external influences.

The polymer sheet material actively displaces fragile and heavy silicate glass. It is much more actively used in the glazing of building structures.

Using polycarbonate, equip the terraces and greenhouses, build canopies, visors over the entrance groups and roofs of the arbors. It serves as roofing, a light-conducting element of panoramic windows, wall cladding.

Polycarbonate, in contrast to the glass, can keep a fairly impressive load without cracking and deformations. It is suitable for overlapping large spans, does not create risky situations arising from the destruction of large-scale panoramic glazing.

Material of synthetic origin does not require an extremely careful relationship during transportation, delivery to the place of work and the production of installation work. Easy to process, does not create complications in the street. While working with it, it is practically not suitable for the further use of waste and spoiled pieces.

According to structural indicators, sheet polycarbonate is divided into two subspecies, it is:

• Monolithic. Material with monolithic structure and equal characteristics throughout the thickness. On the cut sheet looks like the usual glass, but differs in 200 times greater strength. Nuts, though to the limits specified by the manufacturer.
• Cell. Material with characteristic "honeycombs", if you look at its cut. In essence, these are two thin sheets, between which remote longitudinal partitions are located. They form a cellular structure, and also serve as stiffeners.

Both varieties are suitable for the formation of rounded surfaces, which is absolutely impossible when using glass. But wishing to realize an interesting idea should take into account the bend radius, which is necessarily indicated by the material manufacturer in the technical documentation.

Both types of materials are obtained as a result of polycondensation of two chemical components: definlopropane chloranhydrite and coalic acid. The viscous plastic mass is created as a result, from which a monolithic or cellular polycarbonate is formed.

In order to get a full-fledged idea of \u200b\u200bboth varieties, we will deal with the specifics of their production and the features of the application.

Monolithic polycarbonate sheets

The starting material for the production of monolithic thermoplastic polymer is supplied in the format of granules. The manufacture is carried out according to extrusion technology: loading granules into an extruder, where it is stirred and melted.

The softened uniform mass is pressed through the extruder fiber - the plane device, at the outlet of which the polymer plate is obtained equal to the thickness at all points. The thickness of the slab polycarbonate varies from 1.5 mm to 15.0 mm. Simultaneously with the stove thick, the required dimensions are attached.

Monolithic polymer plates are released in an extensive range, they differ:

• Broadcasting qualities. There are transparent, transmitting up to 90% of the light flux, and matte, practically not conductive light.
• By relief. Flat and wavy. Polymer transparent and non-luminous slate is one of the varieties of monolithic polycarbonate.
• In color. In the suggested buyers abundance of trading positions there are materials of a variety of spike.

Among the positive qualities of the monolithic polycarbonate there are zero moisture absorption. It does not absorb atmospheric water and domestic evaporation at all, therefore does not gither and does not create conditions for the resettlement of fungal colonies.

The monolithic option is not afraid of low and high temperatures, works perfectly in a wide range. In hot weather, like all polymers, is inclined to linear expansion, which is required to be taken into account when designing and carrying out installation work.

Cellular polycarbonate panels

The production of cellular polymer material is different from the manufacture of a monolithic fellow only form of the filler. When mauling, a multilayer material with long longitudinal small sections can be created through it.

In the formed by the filler channels there is air, so that the insulating qualities of the polymer product increase significantly, while the weight is significantly reduced.

Positions from the cellular range differ:

• According to the overall thickness of the panel. At the disposal of architects and designers now there is a cellular material with a thickness of 4.0 mm to 30.0 mm. Naturally, the thickness of the sheet, those worse it bends and is less suitable for the formation of rounded planes.
• In color and lighting quality. Due to the characteristics of the structure, cellular polycarbonate cannot carry out more than 82% of light rays. Coloric gamma is not inferior to monolithic nomenclature.
• By number of layers and the form of cells. The layers in the cellular panel can be from 1 to 7m. The ribs of rigidity, which are simultaneously with the remote elements and walls of air channels, can be located strictly perpendicular to the top and bottom surface of the sheet or be to them at an angle.

Channels created by ribbed-jumpers can be safely attributed to both the pluses of the material and its minuses. Despite the perfect inability of the polycarbonate itself to absorb water, they are just the opposite, they can "sue" moisture from the nearby of soils and plants, easily miss domestic evaporation.

In order for the channels to penetrate the channels, which, by the way, significantly reduces the priority insulating qualities of cellular polycarbonate, when performing installation work, they should be covered with flexible profiles - linear mounting parts. They are used both to protect the edge and for connecting adjacent sheets into one design.

Optimization of quality characteristics

Polycarbonate panels are excellent building materials, but still it is not devoid of flaws. It misses the Ultraviolet group A and B. to a minus, we will draw sensitivity to the effects of sunlight, the tendency to uneven dispel the rays and the ability to maintain burning.

Consider what methods producers of polymer sheets are struggling with negative properties. So we will understand what should be paid attention to, choosing polycarbonate for private construction.

Ultraviolet protection

The substantial minus of the plates created from polycarbonate is not in vain recognize the ability to skip the ultraviolet component of solar radiation, harmful to, for example, plants in the greenhouse. It is not useful for resting under a canopy, and for swimming in the pool with a polymer pavilion.

In addition, UV negatively acts onto the polycarbonate sheet itself, which turns yellow, purre, eventually destroys. In order to protect the material and equipped with its help, the outer side is supplied with a layer that plays the role of a reliable barrier from destroying rays.

Previously, the protective layer was carried out with a lacquer coating, the lack of non-uniformity of application belonged, the ability to crack and quickly more. It can now be found on counterfeit products, since manufacturers there are no equipment nor compositions to perform proper protection against UV.

High-quality polycarbonate is not covered with a protective sheath, it seems to be swam in its top layer. The method of such application is called coextrus. As a result of mixing two substances at the molecular level, a shield is created, impenetrable for ultraviolet radiation.

The thickness of the layer created by mooring is only a pair of tens of microns. In essence, it represents the same polycarbonate, but enriched with UV stabilizer. In the course of operation, the layer does not crack, it does not crumble and does not appear, but faithfully serves the owners exactly so much, so much is used by the polycarbonate panel.

It should be noted that the presence of a stabilizer is not determined visually, its presence confirms only the technical documentation from the manufacturer, the cost-effective reputation. In order to determine this substance in the polycarbonate, the optical additive is also made in the process of its compartment.

You can consider the optical additive under an ordinary ultraviolet lamp, but the stabilizer itself will never see. Therefore, it is better to buy material in responsible stores that purchase polycarbonate from proven suppliers. Only in this case "expire" to counterfeit will be almost impossible.

I also remember that the ultraviolet stabilizer is not brought to the entire thickness of the sheet. This concentration is simply irrational, and the price would increase hundreds of times on the product. Therefore, the assurance of the seller or the manufacturer of the material is that the stabilizing agent is made on all power, it is possible to regard the deception and desire to sell fake.

The side with which the stabilizer is fused is indicated on the material as "top". Installing polycarbonate sheets need only so that it creates an outer surface and the first met the sun's rays. Only in this case, the protection against ultraviolet will absolutely accomplish the duties assigned to it.

Light scattering additive

The ability to dispel light is a property, very useful in a greenhouse. Therefore, attention should be paid to it if the polycarbonate sheets are bought for the construction of the greenhouse.

The light scattering provides more complete coverage of the illuminated territory by redirecting the sun rays, ensures uniformity of the supply of light to all plants in the closed object. In addition, the scattered rays inside the greenhouse are additionally reflected from various surfaces, which further enhances the flow of light.

The property to distribute uniformly solar rays from monolithic sheets is much higher than that of cellular panels. And since in the arrangement of greenhouses is used predominantly cellular option, then the percentage of light scattering is necessary to inform the seller or find information about it in the product passport.

Need to remember that:

• At cellular transparent material, this property usually does not exceed 70-82%.
• Opaque color modifications varies from 25 to 42%.

Polycarbonate begins to refract and disperse light after administration of the LD-microscopic particles forming the specified effect.

This additive is made in the production of transparent panels, due to which the ability to skip the light in monolithic sheets increases to 90% (data for a 1.5 mm thick material). It is added in the manufacture of white polycarbonate, the light-conducting ability of which varies as a result in the range from 50 to 70%.

Introduction of a combustion inhibitor

Like all polymer compounds, polycarbonate without the use of specific additives will support fire. After making inhibitors, this quality decreases significantly. Monolithic sheets and cellular panels are long resisting ignition and do not emit poisoning toxins during burning.

Standard monolithic polycarbonate refers to the G2 group by the parameters of the ignition, cellular to G1. Those. Monolithic sheets are moderately combustible, and the cellular panels weakly thunder.

At the request of customers, monolithic sheets can also be manufactured with compliance with the requirements of the group G1. The buyer in this case should receive a certificate for a product with the corresponding characteristics. According to flammability indicators, the ability to distribute fire and toxicity can also be variations.

Exception of the phenomenon of the inner rain

Cellular polycarbonate is very popular in the construction of greenhouses, veranda, indoor pavilions for pools, greenhouses, terraces. The use of polymer panels practically eliminates air movement or significantly reduces its speed. The situation aggravates the specific fasteners used in construction, providing tightness.

Despite the presence of ventilation components in structures suitable from polycarbonate, condensate loss is almost impossible to completely exclude. Natural evaporation and condensate are settled on the inner surface, reduce light engineering.

Condensate and vapor water negatively affect plants, contribute to their winding in hermetic greenhouses. The negative impact turns out to be on wooden parts of the structures, on the surface of which the destructive fungus spreads. An unhealthy atmosphere is formed in the indoor pools.

How to eliminate fogging? Yes, applying fog coverage, which received the technical term anti-fog (against fog). After it applies to the inner surface of polycarbonate structures, evaporation and condensate are not delayed due to changes in the tension on the surface of the drops.

The multicomponent composition forms conditions for the uniform distribution of water along the polymer surface. Water enters into interaction with it, and not with neighboring similar molecules. Evaporation and condensate are in the end do not turn into large drops, creating a threat to plants and people when dropping, and quickly evaporate.

Accounting for thermal expansion

In order to the construction worked with the use of polycarbonate, it is necessary to take into account that as a result of thermal exposure, sheets and panels are able to increase in size.

The polycarbonate building material is designed for normal operation in the temperature range from -40º C to + 130º C. Naturally, with plus values, the polymer will change in the linear direction.

Accounting for thermal expansion is required at the project development stage, and information about the linear size of thermal expansion is extremely important for the designer.

The average values \u200b\u200bof thermal extensions for polymer panels are:

• 2.5 mm for each temporon meter for transparent, dairy material for and products close to milk color of light tones;
• 4.5 mm for the material of the dark color: blue, gray, bronze samples.

In addition to designers, the ability to thermal expansion should be taken into account by installers, because Fasteners need to be installed in a special way. In order for the sheets and panels the ability to move, the holes for self-tapping screws drill more diameter of their trunk, and also use hardware with large caps and compensators.

Cellular panels and monolithic polymer sheets are placed so that the gap remains between them. Then, when expanding the polymer elements, there will be a reserve, thanks to which they will not "push" each other, resting in the edges. This clearance closes the flexible profile in the structures.

If, when designing and assembling structures, the thermal expansion is taken into account, the structures will not necessarily serve as more, guaranteed by the term manufacturer. The components arranged using polycarbonate sheets and panels will not crack and destroy from tension and oversupply the voltage.

Independent home builders should also be remembered for the tendency of polymer sheets and panels to expand in thermal effects, both direct and indirect, that is, what is happening under the conditions of increasing the degree in the surrounding space.

The information proposed by us does not just introduce interested visitors with the popular building material and the specifics of its use.

We tried to explain how to choose a worthy product of your attention, which will serve as a guaranteed period and, for sure, much longer. Accounting in the description of the criteria and councils is necessary to achieve a positive result, both in the acquisition and in the construction.

Polycarbonate is a colorless solid polymer plastic. Production is used in the form of granules. It has ease, high strength, transparency, plasticity, frost resistance and durability.

Also, this material is a good dielectric. Polycarbonates from a chemical point of view - synthetic polymers.

Special properties of polycarbonate are achieved due to the unique structure of its macromolecules. Since polycarbonate is a thermoplastic (thermoplastic polymer) during solidification, it is able to restore its properties.

It is worth noting that such a material may be repeatedly recycled, which makes it environmentally attractive. Polycarbonate make ispolycarbonate granules on principles. The applied UV protective layer has reliable protection against direct sunlight.

Polycarbonate sheets are of great popularity for the device, due to their unique operational properties, as well as a wide range of applications. The main advantages of polycarbonate include:

• ease;
• transparency;
• simple installation;
• strength;
• flexibility;
• ease of processing;
• resistance to negative environmental impacts and chemical elements;
• sound and thermal insulation;
• safety.

Polycarbonate is allowed and monolithic. Cellular polycarbonate is widely used in construction, as it is light enough, but at the same time durable material. Sufficient plasticity and high impact resistance allows you to get products with thin walls without losing the main properties.

The monolithic polycarbonate is less common. It is a solid plate, which is used when lining various construction objects. Products are obtained sufficiently strong to different shocks and remove the need to use a metal frame.

Polycarbonate sheets due to their flexibility are the ideal material for overlapping even the most difficult from the geometric point of view of structures. Installation of polycarbonate slabs will not be much difficulty. Comfortable polycarbonate profiles are used, which have the same color gamut and mechanical properties. Sheets are perfectly handled by ordinary cutting tools.

Polycarbonate granules are the main raw material for the manufacture of sheet PCs. Sheet polymer is widely used in the production of light technology, clutch details, parts of mechanical engineering and electrical parts.

Also without using polycarbonate it is impossible to do in the construction, furniture manufacturing, manufacture of weapons, means of protection and sports goods, information carriers, etc. Very often, polycarbonate is used as a zero substitute. Dachini use such material for equipment and greenhouses.

Polycarbonate has high strength and can be varying degrees of transparency and different colors. Polycarbonate products are characterized by a high degree of fire safety. During the impact of fire on the polymer, it does not burn, but melts and at the same time, not highlighting toxic substances.

It is completely environmentally friendly material. It is based on coalic acid salts, which is unable to damage the environment. When interacting with fire in the air, pairs of heavy metals and other harmful substances are not distinguished. The safety of the polymer is explained by the fact that it is used in such sectors as medicine and the food industry.

Polycarbonate is a modern material that is perfectly replaced by glass, while not inferior to him in many properties.

Polycarbonate is a polymer, which, due to its features, is defined as a synthetic weakly important material. If you compare this material with acrylic and glass, it turns out that the polycarbonate is much longer (100 times compared with glass and 10 with acrylic). The broad and temperature range of use, in which the properties of the material remain unchanged - from -40 ° C to + 120 ° C.

It is made from special raw materials - polycarbonate granules. By special processing, plates of a particular type of polycarbonate are smelted. Polycarbonate is used quite widely due to its properties in construction, aircraft construction, medicine, household appliances and electronics, where it is necessary to create a lightweight, but durable case.

Two types of polycarbonate distinguish:

• monolithic;
• cell.

Monolithic polycarbonate is a single plate, in appearance similar to glass. However, polycarbonate is stronger than glass 100 times, 2 times easier and passes more light (up to 90%).

The thickness of the panel can be 0.75-40 mm. Often there is a multi-layered monolithic polycarbonate. Color gamut and texture of layers can be different. In addition, different properties often give different layers: for example, one is durable, the second - does not miss the light, and the third has a matte surface. A monolithic polycarbonate with two layers that do not miss ultraviolet received widespread.

In the construction sphere, horizontal structures are built. It is not necessary that they have a strict rectangular shape - it may be a rounded overlap.

Rounded monolithic polycarbonate

The curvature of the form is achieved by using hot-form technology. For technology, special domes are used by a radius of 4-5 m with a rectangular floor. To control the thickness of the polyterite polycarbonate made, powerful lights carried out throughout the domestic area of \u200b\u200bthe dome are used.

The dome with the raw material is immersed in the furnace, where the temperature is gradually the temperature and circulates the air. Preheated to a certain temperature sheet stamps. Impact resistance of past polycarbonate is obtained very high due to the fact that in the process of stamping the parts are amplified by special ribs. It is removed the need to insert metal ribs ribs, due to which the lightweight design is preserved.

Another option is a wave profiled polycarbonate

Cellular polycarbonate

Structurally, these are two (or more) layers of the plates, between which the longitudinal jumpers are carried out - rigidity ribs.

Cellular polycarbonate is also called cellular or structured. However, the "Cellular Polycarbonate" name was firmly consolidated in the construction sector. Cellular polycarbonate is used to create roofs, canopies, ventilation lanterns on the roofs of industrial buildings and premises.

Important! Cellular polycarbonate is performed by melting the granules heated to the molten state through the forming part, which determines the shape and dimensions of the future sheet.

The advantages of cellular polycarbonate that determines the scope of its application includes the following:

• low weight (1 m2 sheet weighs from 1500 to 3500 g, which is 6 times less glass);
• low thermal conductivity;
• high sound insulation rates (2 times higher than that of glass);
• great strokeiness;
• high bearing abilities;
• high light light (up to 85% - also more than the glass);
• flexibility;
• resistance to the effects of many aggressive chemicals, etc.

Important! Polycarbonate has a negative property that should be taken into account in the process of designing the construction site - when exposed to high temperatures, the material begins to increase in the amount, which can suffer horizontal overlaps with a large area or carrier structures.

Also polycarbonate, like glass, poorly tolerates mechanical impact. For successful installation of overlaps, it is customary either not to remove the protective film, or to process the surface processing with special compositions.

Prices for cellular polycarbonate

cellular polycarbonate

Cellular polycarbonate in agriculture

Cellular polycarbonate is widely used in the agricultural sphere. It is highly appreciated by stroke resistance, material ability to disperse direct solar rays, long wear and insulating properties. In addition, cellular polycarbonate passes only part of ultraviolet rays, which is enough for normal vital areas of plants. Thanks to these properties, cellular polycarbonate is actively used to erect greenhouses and greenhouses not only on an industrial scale, but also for private purposes.

For the construction of greenhouses and greenhouses, cellular polycarbonate sheets with a thickness of 8 mm are usually used. It is this thickness that is considered a golden middle - a combination of cost and technical characteristics is the most successful. Many manufacturers specially produce a cellular polycarbonate 8 mm with a coating that does not allow to linger on the inner surface of water, which improves the light-pain ability of the finished greenhouse.

Monolithic and cellular polycarbonate - what is common?

Both varieties of polycarbonate have general properties, including:

• excellent light light;
• ease;
• strokeness;
• low thermal conductivity.

From both varieties often build transparent overlaps of the most complex forms in both private and in commercial construction. Most often, polycarbonate floors can be found in the design of transitions, gyms, museums, shops and shopping centers.

The standard produces polycarbonate sheets of different thicknesses - 4 mm, 6 mm, 8 mm, 10 mm, 16 mm, 20 mm and 25 mm. In the domestic market, there are sometimes sheets with thickness 32. One sheet, as a rule, has dimensions of 2100 * 6000 mm or 2100 * 12000 mm.

For construction, 8-10 mm polycarbonate is usually used, and when heat resistant is needed - over 20 mm thick.

Polycarbonate in private construction

Polycarbonate has become an affordable broad mass recently and immediately gained popularity. Its relative cheapness and excellent properties have found a consumer response, and the material began to apply in all spheres of life, including in private construction.

Recently, the construction of polycarbonate fences has gained wide popularity. The ability to create fences of an unusual form, good insulation from noise and ease of installation made polycarbonate one of the most favorite materials among designers and architects.

A large role in universal recognition is the fact that polycarbonate can be light and matte, different colors and forms. Large space for fantasy and the ability to create a non-standard design.

Polycarbonate is easy to clean, thanks to which it will just take care of the fence. To care for a polycarbonate fence, enough water and hb fabric. As an additional detergent, any means can be used as part of which there is no ammonia. Soundproofing properties are also a big plus for such a fence.

Polycarbonate garage buildings

Two designers - Tapio Spelman and Christian Grau - wondered how to create an unusual and practical garage for premium cars so that it looks modern, while the car was in sight and safe at the same time. The decision came almost immediately: they developed a garage with transparent polycarbonate walls with the addition of liquid crystals capable of hiding the car from prying eyes. When implementing this project at the output, a beautiful building is obtained, which perfectly performs its functions and pleases the eye.

Greenhouses, greenhouses and winter gardens from polycarbonate

Fashion for the use for the device The greenhouse film gradually leaves. Film compared to polycarbonate is unprofitable and impractical - even if its integrity does not break, then after 2-3 years they will inevitably self-disseminate under the influence of sunlight. In addition, the film needs to be removed on the winter season and set back in the spring, which provides additional problems. All of the above-described in tandem with nonesthetics make this material completely inconvenient and problematic.

It is much easier and easier to arrange. Many firms supply ready-made designs with galvanized framework that you only need to collect.

Advantages of polycarbonate greenhouses:

• long service life (up to 25 years);
• long service life of galvanized frame (up to 25 years);
• no need to put the foundation - the framework perfectly keeps on any surface;
• construction mobility - a greenhouse or a greenhouse can be moved to another place;
• ease of assembly / disassembly;
• extension of the yield due to the optimal climate;
• ability to equip a winter garden;
• the gathered greenhouse occupies little place;
• the kit includes the entire necessary fastener, which reliably fixes the structure in the assembled state.

Unlike greenhouses from other materials, polycarbonate structures provide a uniform distribution of light rays on all plants. For example, if the greenhouse is covered with glass, ultraviolet rays, not reflecting, falling only on the tops of the plants, while the lower part remains in the shade. In such circumstances, the plants often ill and die.

Polycarbonate provides optimal microclimate plants for efficient growth. In addition, galvanized iron, from which the framework is made, is distinguished by durability and in that it does not have material value in the eyes of criminals.

Important! For lovers of aesthetics and landscape design, polycarbonate will become a real gift - the ability of cellular polycarbonate to take the most complex forms allows you to build the structures of any kind.

The greenhouse from polycarbonate is much better held heat. If you have a heated greenhouse or a winter garden, then in a year you can save about 30% of the fuel used.

It can be useful

Below are some useful information and use of polycarbonate.

Cellular, or otherwise - structured or cellular polycarbonate received its name due to a special internal structure: its design can be two, three or four-layer, filled with a certain number of rigid rigids forming triangles, cross-shaped connections or square. Considering the sheet in the context you can see its similarity with bee honeycombs. Due to such structure, the material has excellent strength characteristics and a high flexibility coefficient, and air enclosed in cells ensures its heating saving properties.

Cellular polycarbonate - how it is manufactured

Polycarbonate is used for the manufacture of cellular material - granulated colorless plastic mass, characterized by ease, frost resistance, dielectric properties, durability. The unique structure of the macromolecules of polycarbonate is the main cause of unique properties, inherent in it.

Thermoplasticity of the material allows it to be recovered in the process of solidification after each melting process, i.e. Material can be recycled repeatedly, which is very important from the point of view of environmental friendliness.

The production of material is carried out by extrusion, i.e. Putting a melted liquid viscous substance through the forming tool. As a result, a canvas with a given cross-sectional shape is obtained.

Properties and advantages of cellular material

Immediately it can be noted that the polycarbonate is relatively different from any transparent building material - none of them possess similar positive qualities in full.

Cellular polycarbonate is different:

1. The low thermal conductivity coefficient that provides higher than that of glass heat-saving quality material, which allows almost half to reduce energy consumption for heating or cooling rooms.
2. The multilayer structure of the material provides good sound absorption, and, accordingly, good noise insulating qualities.
3. The material dispels the light rays well, its transparency is 86%, when the light passes, the shadow does not discard.
4. The exploitation of the material can be carried out at temperatures from -40 with to +120 s, i.e. It can be used in virtually any natural zone, the qualitative characteristics of the material are very slightly dependent on the changes occurring in the environment. He is not susceptible to the effects of chemical reagents.
5. Polycarbonate has a slight weight, approximately 16 times less than the window glass and 6 times less than the acrylic sheet of the same thickness, the use of material allows to obtain savings due to the design of a less powerful foundation and reducing the cost of the construction of support structures. Installation work can be performed without the use of special construction equipment.
6. The material has a high viscosity providing its impact resistance (200 times greater than that of the sheet glass), it is resistant to bending loads and gap. In case of damage with very strong impact, sharp fragments are not formed. The polycarbonate coating can withstand the loads rendered by the accumulated snow, does not break away from the wind gusts, as a plastic film, which makes it an ideal option for the coating of greenhouses. Good material flexibility allows you to use it when installing roof designs with a complex geometry, including arched and vaulted.
7. The polycarbonate is distinguished by a flammability of ignition, it does not burn, but under the influence of open fire melts forming a web-like fiber, toxic substances are not allocated.
8. The constancy of the material characteristics of the material is provided by the protective layer on the front of the sheets, which delaying the ultraviolet part of the solar spectrum.

Cellular polycarbonate - sheet size and scope depending on thickness

A cellular polycarbonate is produced in a wide range of colors, its base colors:

• warm - Red, Brown, Bronze, Orange, Yellow, Milk,
• cold - White, Blue, Turquoise, Green,
• you can also find a transparent panel.

If we talk about the size of sheets, you should specify that polycarbonate is produced in several versions:

• monolithic, thickness from 2 to 12 mm, with standard sheet dimensions 2,05x3.05 m,
• a cellular, thickness of 4 to 32 mm, with a sheet dimens 2.1x6 m or 2.1 12 m,
• profiled, thickness of 1.2 mm, sheet size of 1.26x2.24 m, profile height up to 5 cm.

Depending on the thickness of the sheets, cellular polycarbonate can be different, it is recommended to use when constructed:

• 4 mm - canopies and greenhouses, showcases, exhibition stands,
• 6 mm - canopies, greenhouses, visors,
• 8 mm - greenhouses, roofs, canopies, partitions,
• 10 mm - continuous glazing of horizontal and vertical surfaces, manufacture of noise protection barriers, canopies,
• 16 mm - roofs over large facilities,
• 32 mm - for roofs with increased standards for loads.

Based on such a wide range of products before starting construction, it will be necessary to study the properties and decide which polycarbonate is rationally apply in each specific construction.

Basic principles of working with polycarbonate

Since the sheets of material have quite large dimensions during construction, it will be necessary to give them the necessary dimensions, i.e. cut. There are no special problems with cutting polycarbonate if the thickness of the sheet is from 0.4 to 10 mm, then you can use a building retractable sharp knife. The protective film from the surface is not recommended - it will protect against scratches.

The incision should be done carefully, providing an accurate, straight line. For cutting a thicker material, use the saw with an emphasis operating in high-speed mode. The teeth of such a saw should be made of reinforced alloys, small, undelivered. You can also use the electric bike.

When working, the sheet should be maintained to eliminate its vibration. Chip, which will fall inside the sheet during cutting required to delete at the end of work.

To mount the polycarbonate, you will need to drill holes in the sheets. For this, sharp drills of steel are used. Place the space for drilling is required so that it is located between the inner ribs of stiffness. The distance from the opening to the edge should be about 10 mm.

The bend of the cellular polycarbonate can be exclusively over the lines of channels, along the length of the sheet. The bend radius may exceed a sheet thickness of 175 times.

Since there are emptiness inside sheets, then special attention should be paid to the processing of their skiddes. If the sheets are mounted in a vertical or inclined position, the closures of the ends in the upper part should be performed by a self-adhesive aluminum strip, and in the lower - perforated, which can protect the material from penetration inside the dirt, but ensuring the ability to flow condensate.

When using polycarbonate in the construction of arched structures, it will require the closure of its ends with a perforated film. Materials for sealing should be selected by the colors of the shade panels.

• Aluminum sealants are considered the highest quality, they are durable and easy to use.
• When using a non-perforated sealant, it should drill the holes of the smallest diameter - to exit condensate and vapor.
• Leave the ends open is not recommended - it will help reduce the transparency of the panels and reduce their life.
• The ends are not recommended to stick to the usual scotch.
• When installing sheets, they should orient them in such a way as to ensure the possibility of the unimpeded condensate output.
• Plan the installation of panels in such a way that with the vertical installation of stiffness, the rigid rib was located vertically, when building a scope surface - longitudinally, for arched - arcuate.
• To perform external work, use material with a layer protecting it from ultraviolet radiation.

Polycarbonate fastening

Bearing longitudinal support supports are mounted in increments:

• for 6-16 mm sheets - 700 mm,
• for 25 sheets - 1050 mm.

When calculating the distance between transverse supports are taken into account:

• expected wind or snow loads,
• the angle of inclination.

The distance can be from 0.5 to 2 m.

For fastening polycarbonate, self-sustaining bolts or thermoshabs are used, one of which is a plastic plate with a high rod, another -ovenator, also included a snap cap. Thermoshaba provides a durable and hermetic compound without cold bridges and panel compression. What avoiding the problems caused by the temperature expansion of the hole must have a diameter greater than the section of the floor of the washer for a couple of millimeters.

Nails or rivets for fastening panels can not be used! Tightening the screw bolts when making installation is not recommended. Improper fastening of polycarbonate with self-draws can lead to a reduction in its operational periods.

If there is a mounting of all-in-block panels, then you should insert them in the folding thickness profile as the panels have the same.

With the help of self-sustaining bolts, they are attached to the longitudinal support. Before starting work, it is recommended to withstand the sheets of cellular polycarbonate in a dry warm room, and only then put their ends with self-adhesive ribbon - in this case, there will be no condensate inside the cellular material. To prevent the ability to damage the surface when the profile is snapped, a wooden cyonya is used.

When installing, it should be borne in mind that polycarbonate are not referred to as static materials, its dimensions, albeit at a small degree (up to 0.065 mm / m with a temperature change by 1 degree), but vary from temperature drops. Therefore, when installing appropriate gaps should be left, but we should not forget about the need to use special fasteners that will prevent panel slipping when the temperature is reduced. It is enough for the frequency margin of 2 mm for each running meter. The above requirements should correspond to the diameters of the holes harvested for fasteners.

Operation of polycarbonate surfaces and care for them

1. Before starting the installation of the panel, it should be stored in a packaged form, they are transported in a horizontal position.
2. It is not recommended to store panels under the right rays of the Sun or in the rain.
3. It is impossible to walk on polycarbonate sheets.
4. Purification of the panels produce a soft wind with a moistened solution of soap or dishwashing agents.
5. It is impossible to use detergents in which ammonia, acid, chlorine, solvents, salts.
6. To remove contaminants, it is impossible to use sharp items - they can scratch the ultraviolet protective layer.
7. The installation of sheets is made in such a way that the side to which the protective film is applied to the outside. On the package, you should find the designation of UV protection.

Polycarbonate in construction is an excellent glass alternative. He has very high traffic permeability due to 90% transparency, as well as it is very light. In addition, polycarbonate a few hundred times tightly the glass - the hammer and the bullets are not terrible to him. It is he who prefers gardeners in the construction of greenhouses, then no degrees or a hurricane can spoil her.

In addition to the installation of greenhouses, polycarbonate material is used to build shop windows, billboards, in the glazing of buildings, balconies and loggias, in the office partitions, as fences in playgrounds or pools and in other transparent structures. This material is aesthetic and pleasant, so it is also used as decor.

Read more about the characteristics and benefits of polycarbonate

Polycarbonate is a transparent polymer plastic that is stored in the form of granules to the very moment of processing. This substance includes: Dnekhatynaya phenol, water, coalic acid, solvents and dyes. At high temperatures, it does not lose its properties, capable of self-restoration, and therefore is environmentally safe.

Important: You should not open the factory packaging until the use of polycarbonate sheets so that the condensate does not hit, and also can not be withdrawn the protective film - it can get dust or insects, it will negatively affect the appearance of the sheet.

Two types of polycarbonate are produced - cellular and monolith. For quality, they are the same. The only difference is that the structure of cellular polycarbonate is cellular (inside it is hollow, there are only partitions between the cells), and the monolith is solid without empty cells inside.

Specifications:

As already mentioned, this material is most like when installing greenhouses - he has excellent thermal insulation.

Fire resistant and not toxic, has the properties of self-effect.

Unrealistic shockproof - use in the construction of fences against vandalism.

Resistant to temperature differences. Not vulnerable under difficult weather conditions.

Important: Although the material does not lose its properties when exposed to high temperature, it can increase up to 4mm - this must be considered when installing and stored.

Due to the fact that the material is very flexible, it is convenient to make arches from it and other structures that need to be given the original geometric shape. For this, a cellular sheet is more often used.

Does not miss ultraviolet. The material itself under the influence of UV is collapsed, but the manufacturers take into account this nuance and add a special protective agent to its composition.

In order not to doubt what type of polycarbonate to choose is a cellular or monolith, remember that the only difference is that the cellular has a smaller weight than the monolith, as well as the cellularly slightly above noise isolation, thanks to emptiness in cells.

Polycarbonate itself is a very lightweight material, you can work with it without the use of special power techniques. Another important advantage is that the material is safe both in montage and in everyday life. If the glass is accidentally hit, it will break, and can perky someone - with polycarbonate such cases are excluded at all.

Polycarbonate Greenhouse Installation Description

Build a greenhouse with their own polycarbonate hands much easier than glass. In addition, the plasticity of the material allows the greenhouse to be a more interesting form.

Polycarbonate is not fragile, unlike glass.

Easily cutting with metal scissors (using a saw or a knife).

Flexibility - you can make the roof in the form of the arch. This will help to avoid sticking, which cannot be said about the installation of a glass greenhouse.

Important: Despite the fact that polycarbonate is quite flexible, you need to observe the measure. It is not worth exceeding the bending radius indicated on the package, this will lead to a disruption of special-coating from ultraviolet.

The foundation and frame of the greenhouse

The first thing is poured the foundation of the greenhouse. If the greenhouse will be located on a soft soil, then the strapping should be made, and then pour a concrete foundation. You can use brick or stone. Such a foundation will last for many years.

The carcass for the greenhouse can be wooden, profiled or metal. It is better to use metallic, because the profiled is not very durable and can progress under pressure, and the wooden need to paint - it is quiet. An ideal option will be a metal corner or square fittings.

Saving frame greenhouse with polycarbonate sheets

First of all, you need to trim the factory film from the sheets. It is better to do this before the trim, then it will be very uncomfortable, and you have to tinker.

Sheets on the outer side of the frame, braziness, using thermoshabs and self-tapping screws are attached.

Try to face a protective coating from UV from the outside.

Bending a cellular polycarbonate can be only in the direction of the rigidity ribs.

No need to tighten the fastenings - the leaf should hold firmly, but it is possible to move freely to be where to expand when heating.

There is nothing complicated to make the installation of the greenhouse. You can, of course, purchase and already the ready-made frame, covered with polycarbonate, which is then only installed on the foundation, but it will cost somewhat more expensive. In addition, it is possible not to guess with dimensions, which will entail extra spending, although you have to decide - both options have their advantages and cons. In the first version you spend your time and strength, but save money, in the second - on the contrary.

Polycarbonate service life

If the polycarbonate is correct to care and observe all precautions when installing, it is capable of listening to several decades longer than the manufacturer.

Polycarbonate care

Polycarbonate is easy to clean. To do this, you can use any dishwashing agent if you do not have a special, and cotton fabric.

Important: The detergent should not contain ammonia, it destroys the material, and use ethyl alcohol for fatty spots! Do not try it with a brush or scraper, only a cotton cloth! Otherwise damage the coating that protects against ultraviolet.

In conclusion, a few words about the coloring of polycarbonate

The main purpose of the color polycarbonate is the impression of beauty and originality of the appearance of the construction. But some experts argue that for the construction of the greenhouse, the color matters not only in the aesthetic plan. It is believed that the green color is not suitable for greenhouses, because the growth of plants, red or orange, is oppressing, on the contrary, it contributes. In any case, if you decide to use this material in construction, then you will be where to show a fantasy.

Polycarbonate care

On an example with a greenhouse, on the arrival of spring, polycarbonate should be cleaned of dirt that accumulates in the winter. Because of the mud, the material loses transparency, and it is stronger from it, which leads to the deformation of the sheet. Watch out for the cleanliness of the structure.

Polycarbonate Easy to clean. To do this, you can use any dishwashing agent if you do not have a special, and cotton fabric.

Important : detergent should not contain ammonia, it destroys material, And for fatty spots, use ethyl alcohol! Do not try it with a brush or scraper, only a cotton cloth! Otherwise damage the coating that protects against ultraviolet.

In conclusion, a few words about the coloring of polycarbonate

Polycarbonate has a rich color gamut, especially cellular. The cast is not so great a variety of colors, because it is used less often than the cellular, but still there is a choice.

Polycarbonate - what it is: material, description, specifications

Polycarbonate in construction is an excellent glass alternative. He has very high traffic permeability due to 90% of transparency, as well as it is very light

Polycarbonate: What is it and what can it be used for?

Traditional material for creating translucent structures (windows, greenhouses, greenhouses, decor elements) for a long time there was a silicate glass. It has a high degree of translucency, however, the fragility and technical characteristics of the glass strongly limited the possibilities of application. The opposite of this expensive, but unreliable material - polycarbonate. This term combines a whole group of transparent synthetic thermoplastics, which have high strength, a large bearing capacity, as well as plasticity. This article will tell about what polycarbonate is, and how it is used for construction.

Composition and production process

All types of polycarbonate belong to the group of thermoplastic synthetic polymers. This material was not designed by scientists specifically, it was opened in the course of research of painful medicines when chemists paid attention to a durable, transparent by-product of the reaction. The secret of the strength of this compound is a special structure of the molecule, which is obtained in the following ways:

1. The method of deadherimation of diphenylcarbonate under vacuum conditions with the introduction of complex bases under the substance under the influence of stepwise temperature increases. This method is good in that the production does not apply solvent, however, to obtain a good quality material will not be obtained, since in any case there is a small amount of catalyst.
2. The method of phosgenation of A-bisphenol in solution with the presence of pyridine is no more than 25 degrees. The positive side of this method is that production occurs at a low temperature in the liquid phase. However, the high cost of pyridine makes this method economically unprofitable for the manufacturer.
3. The interphase polycondensation of A-bisphenol with phosgene in organic and alkaline solvents. The described reaction is low-temperature, which is good for production. However, a lot of water is spent for flushing a polymer, which are discharged into water bodies, polluting the environment.

Interesting! Having excellent specifications, low cost, high bearing capacity and translucency, not inferior to silicate glass, some types of polycarbonate have long been used reluctantly. Since the effects of ultraviolet radiation led to clouding material. The introduction of the substance Ultraviolet absorber brought polycarbonate to a new level by making the most rational solution to create translucent structures and anti-vandal glazing.

Under the term "polycarbonate" combine a large group of synthetic linear polymers, which are derivatives of phenol and coalic acid. The molecular structure of the granules of this material is an inert, translucent, stable granule. Different production conditions (increased pressure, temperature, medium) give substance different specifications, allowing you to create polycarbonate with different properties. Currently, 2 main types of this building material are produced:

• Monolithic. This material in appearance resembles silicate glass, it is transparent, has a flat, smooth surface. Sometimes monolithic polycarbonate is called "shockproof glass", as it has high mechanical strength, impact resistance, flexibility and at the same time ease. Operational characteristics and various polycarbonate thickness of the monolithic type allows you to use this unique material for decorative glazing, curvilinear decorative elements, anti-vandal structures of the urban environment (stops, pointers, road signs, billboards). However, it costs several times more expensive than a cellular counterpart.

Important! Manufacturers produce transparent, translucent and matte polycarbonate, which can be colorless or color. Colorless transparent material that has a light transaction 84-92% is used for the construction of greenhouses and greenhouses. And translucent and matte color are suitable for decorative glazing of commercial and administrative buildings.

Dimensions and properties

Various types of polycarbonate plastic have different operational and specifications, including impact resistance, carrying capacity, thermal insulation qualities and translucency. The properties of the material also depend on the structure and thickness of the sheet. Choosing polycarbonate worth considering the following parameters:

1. The width of the cellular polycarbonate plastic is 210 cm, and the monolithic - 2.05 m.
2. Manufacturers produce cellular polycarbonate plastic in the form of sheets up to 12 m long, which is convenient for the installation of greenhouses and greenhouses. Monolithic polycarbonate are produced with a length of up to 6 m.
3. Cellular polycarbonate is released with a thickness of a sheet of 4 mm, 6 mm, 8 mm, 10 mm, 16 mm, 20 mm, 25 mm, it depends on the shape of the cells and the number of layers in the material. The thickness of the polycarbonate of the monolithic type is 6 mm, 8 mm, 10 mm or 16 mm.
4. The monolithic polycarbonate weighs more than a cellular analogue, 1 square meter of such a coating is 4.8 kg, however, it is still 2 times less than the weight of the glass of the same area. Cellular polycarbonate weighs 0.8 kg / m2.
5. The heat resistance of both types of material is 145 degrees, despite this, it refers to the class of self-fighting.
6. The impact resistance of the monolithic polycarbonate is more than 400 J, which is ten times more impact-resistant glass. The sheet of cellular polycarbonate has an impact resistance of more than 27 J.

Note! Cellular and monolithic polycarbonate have different light-permeability coefficients. The coefficient of lighting of monolithic polycarbonate plastic is 91%, for comparison, this indicator is 87-89%. Cellular polycarbonate has a translucency of 80-88%.

Benefits

The operational and technical characteristics of polycarbonate plastic make it possible to use this material in many areas of construction. Lightweight, impact resistance and transparency of polycarbonate and the low cost of production gave him the opportunity to compete with silicate glass. The indisputable advantages of this material are considered:

• A light weight. The monolithic plastic is 2 times lighter than glass, and cellular in 6, which allows you to create lightweight structures that have not dried up with extra supporting elements.
• Strength. High bearing capacity gives polycarbonate resistance to intense snow, wind or weight loads.
• Transparency. The monolithic type of material misses even more light than silicate glass, and cellular polycarbonate plastic skips up to 88% of the visible spectrum.
• Insulation qualities. Polycarbonate, especially cellular, is an excellent material for sound and noise insulation.
• Safety. When breaking polycarbonate, sharp fragments are formed, which are injured.

Taking into account! All types of this material does not require serious care, they are wedge with the addition of soap or dishwashing agents. In no case can not be used to clean ammonia, which destroys its structure.

What is a cellular polycarbonate

Polycarbonate, what it is, cellular polycarbonate sizes, application, methods cutting, fastening

Cellular, or otherwise - structured or cellular polycarbonate received its name due to a special internal structure: its design can be two, three or four-layer, filled with a certain number of rigid rigids forming triangles, cross-shaped connections or square. Considering the sheet in the context you can see its similarity with bee honeycombs. Due to such structure, the material has excellent strength characteristics and a high flexibility coefficient, and air enclosed in cells ensures its heating saving properties.

Cellular polycarbonate - how it is manufactured

Polycarbonate is used for the manufacture of cellular material - granulated colorless plastic mass, characterized by ease, frost resistance, dielectric properties, durability. The unique structure of the macromolecules of polycarbonate is the main cause of unique properties, inherent in it.

Thermoplasticity of the material allows it to be recovered in the process of solidification after each melting process, i.e. Material can be recycled repeatedly, which is very important from the point of view of environmental friendliness.

The production of material is carried out by extrusion, i.e. Putting a melted liquid viscous substance through the forming tool. As a result, a canvas with a given cross-sectional shape is obtained.

Properties and advantages of cellular material

Immediately it can be noted that the polycarbonate is relatively different from any transparent building material - none of them possess similar positive qualities in full.

Cellular polycarbonate is different:

1. The low thermal conductivity coefficient that provides higher than that of glass heat-saving quality material, which allows almost half to reduce energy consumption for heating or cooling rooms.
2. The multilayer structure of the material provides good sound absorption, and, accordingly, good noise insulating qualities.
3. The material dispels the light rays well, its transparency is 86%, when the light passes, the shadow does not discard.
4. The exploitation of the material can be carried out at temperatures from -40 with to +120 s, i.e. It can be used in virtually any natural zone, the qualitative characteristics of the material are very slightly dependent on the changes occurring in the environment. He is not susceptible to the effects of chemical reagents.
5. Polycarbonate has a slight weight, approximately 16 times less than the window glass and 6 times less than the acrylic sheet of the same thickness, the use of material allows to obtain savings due to the design of a less powerful foundation and reducing the cost of the construction of support structures. Installation work can be performed without the use of special construction equipment.
6. The material has a high viscosity providing its impact resistance (200 times greater than that of the sheet glass), it is resistant to bending loads and gap. In case of damage with very strong impact, sharp fragments are not formed. The polycarbonate coating can withstand the loads rendered by the accumulated snow, does not break away from the wind gusts, as a plastic film, which makes it an ideal option for the coating of greenhouses. Good material flexibility allows you to use it when installing roof designs with a complex geometry, including arched and vaulted.
7. The polycarbonate is distinguished by a flammability of ignition, it does not burn, but under the influence of open fire melts forming a web-like fiber, toxic substances are not allocated.
8. The constancy of the material characteristics of the material is provided by the protective layer on the front of the sheets, which delaying the ultraviolet part of the solar spectrum.

Cellular polycarbonate - sheet size and scope depending on thickness

A cellular polycarbonate is produced in a wide range of colors, its base colors:

• warm - Red, Brown, Bronze, Orange, Yellow, Milk,
• cold - White, Blue, Turquoise, Green,
• you can also find a transparent panel.

If we talk about the size of sheets, you should specify that polycarbonate is produced in several versions:

• monolithic, thickness from 2 to 12 mm, with standard sheet dimensions 2,05x3.05 m,
• a cellular, thickness of 4 to 32 mm, with a sheet dimens 2.1x6 m or 2.1 12 m,
• profiled, thickness of 1.2 mm, sheet size of 1.26x2.24 m, profile height up to 5 cm.

Depending on the thickness of the sheets, cellular polycarbonate can be different, it is recommended to use when constructed:

• 4 mm - canopies and greenhouses, showcases, exhibition stands,
• 6 mm - canopies, greenhouses, visors,
• 8 mm - greenhouses, roofs, canopies, partitions,
• 10 mm - continuous glazing of horizontal and vertical surfaces, manufacture of noise protection barriers, canopies,
• 16 mm - roofs over large facilities,
• 32 mm - for roofs with increased standards for loads.

Based on such a wide range of products before starting construction, it will be necessary to study the properties and decide which polycarbonate is rationally apply in each specific construction.

Basic principles of working with polycarbonate

Since the sheets of material have quite large dimensions during construction, it will be necessary to give them the necessary dimensions, i.e. cut. There are no special problems with cutting polycarbonate if the thickness of the sheet is from 0.4 to 10 mm, then you can use a building retractable sharp knife. The protective film from the surface is not recommended - it will protect against scratches.

The incision should be done carefully, providing an accurate, straight line. For cutting a thicker material, use the saw with an emphasis operating in high-speed mode. The teeth of such a saw should be made of reinforced alloys, small, undelivered. You can also use the electric bike.

When working, the sheet should be maintained to eliminate its vibration. Chip, which will fall inside the sheet during cutting required to delete at the end of work.

To mount the polycarbonate, you will need to drill holes in the sheets. For this, sharp drills of steel are used. Place the space for drilling is required so that it is located between the inner ribs of stiffness. The distance from the opening to the edge should be about 10 mm.

The bend of the cellular polycarbonate can be exclusively over the lines of channels, along the length of the sheet. The bend radius may exceed a sheet thickness of 175 times.

Since there are emptiness inside sheets, then special attention should be paid to the processing of their skiddes. If the sheets are mounted in a vertical or inclined position, the closures of the ends in the upper part should be performed by a self-adhesive aluminum strip, and in the lower - perforated, which can protect the material from penetration inside the dirt, but ensuring the ability to flow condensate.

When using polycarbonate in the construction of arched structures, it will require the closure of its ends with a perforated film. Materials for sealing should be selected by the colors of the shade panels.

• Aluminum sealants are considered the highest quality, they are durable and easy to use.
• When using a non-perforated sealant, it should drill the holes of the smallest diameter - to exit condensate and vapor.
• Leave the ends open is not recommended - it will help reduce the transparency of the panels and reduce their life.
• The ends are not recommended to stick to the usual scotch.
• When installing sheets, they should orient them in such a way as to ensure the possibility of the unimpeded condensate output.
• Plan the installation of panels in such a way that with the vertical installation of stiffness, the rigid rib was located vertically, when building a scope surface - longitudinally, for arched - arcuate.
• To perform external work, use material with a layer protecting it from ultraviolet radiation.

Polycarbonate fastening

Bearing longitudinal support supports are mounted in increments:

• for 6-16 mm sheets - 700 mm,
• for 25 sheets - 1050 mm.

When calculating the distance between transverse supports are taken into account:

• expected wind or snow loads,
• the angle of inclination.

The distance can be from 0.5 to 2 m.

For fastening polycarbonate, self-sustaining bolts or thermoshabs are used, one of which is a plastic plate with a high rod, another -ovenator, also included a snap cap. Thermoshaba provides a durable and hermetic compound without cold bridges and panel compression. What avoiding the problems caused by the temperature expansion of the hole must have a diameter greater than the section of the floor of the washer for a couple of millimeters.

Nails or rivets for fastening panels can not be used! Tightening the screw bolts when making installation is not recommended. Improper fastening of polycarbonate with self-draws can lead to a reduction in its operational periods.

If there is a mounting of all-in-block panels, then you should insert them in the folding thickness profile as the panels have the same.

With the help of self-sustaining bolts, they are attached to the longitudinal support. Before starting work, it is recommended to withstand the sheets of cellular polycarbonate in a dry warm room, and only then put their ends with self-adhesive ribbon - in this case, there will be no condensate inside the cellular material. To prevent the ability to damage the surface when the profile is snapped, a wooden cyonya is used.

When installing, it should be borne in mind that polycarbonate are not referred to as static materials, its dimensions, albeit at a small degree (up to 0.065 mm / m with a temperature change by 1 degree), but vary from temperature drops. Therefore, when installing appropriate gaps should be left, but we should not forget about the need to use special fasteners that will prevent panel slipping when the temperature is reduced. It is enough for the frequency margin of 2 mm for each running meter. The above requirements should correspond to the diameters of the holes harvested for fasteners.

Operation of polycarbonate surfaces and care for them

1. Before starting the installation of the panel, it should be stored in a packaged form, they are transported in a horizontal position.
2. It is not recommended to store panels under the right rays of the Sun or in the rain.
3. It is impossible to walk on polycarbonate sheets.
4. Purification of the panels produce a soft wind with a moistened solution of soap or dishwashing agents.
5. It is impossible to use detergents in which ammonia, acid, chlorine, solvents, salts.
6. To remove contaminants, it is impossible to use sharp items - they can scratch the ultraviolet protective layer.
7. The installation of sheets is made in such a way that the side to which the protective film is applied to the outside. On the package, you should find the designation of UV protection.

Polycarbonate, what it is, cellular polycarbonate sizes, application, methods cutting, fastening

What is polycarbonate cellular polycarbonate, what it is, cellular polycarbonate sizes, application, methods cutting, cell fastening, or otherwise - structured

Technical characteristics of cellular polycarbonate

Polymer materials are widely used in the construction of buildings and structures of various purposes. Cellular polycarbonate is a two- or three-layer panel with longitudinal ribs located between them. The cellular structure provides a high mechanical strength of the sheet with a relatively small specific gravity. To understand and understand all technical specifications of cellular polycarbonate, consider its properties and parameters.

What is a cellular polycarbonate

In cross section, the sheet resembles the cells of a rectangular or triangular shape, hence the material itself itself. Raw materials for it are granulated polycarbonate, which is formed as a result of condensation of coalic acid polyesters and dihydroxy compounds. The polymer refers to a group of thermosetting plastics and has a number of unique properties.

Industrial production of cellular polycarbonate is carried out with the use of extrusion technology from granulated raw materials. Production is carried out in accordance with the technical specifications of Tu-2256-001-54141872-2006. The specified document is also used as a guide in material certification in our country.

The main parameters and linear dimensions of the panels must strictly comply with the requirements of the standards.

The structure of a cellular polycarbonate with a transverse section may be two types:

His sheets are released with the following structure:

2h. - Two-layer with rectangular cells.

3X. - three-layer structure with a combination of rectangular cells with additional inclined partitions.

3h. - three-layer sheets with a rectangular structure of cells, produce a thickness of 6, 8, 10 mm.

5w. - five-layer sheets with a rectangular structure of cells, as a rule, have a thickness of 16 - 20 mm.

5x - five-layer sheets consisting of both direct and inclined ribs produce a thickness of 25 mm.

Temperature Modes of Cell Polycarbonate

Polycarbonate Cellular has an exceptionally high resistance to adverse environmental conditions. Temperature modes of operation directly depend on the brand of this material, the quality of raw materials and compliance with production technology. For the overwhelming majority of panel types, this indicator is from - 40 ° C to + 130 ° C.

Some types of polycarbonate are able to withstand extremely low temperatures up to - 100 ° C without the destruction of the material structure. When heated or cooling the material, it changes its linear dimensions. The linear thermal expansion coefficient for this material is 0.0065 mm / m. C, is determined in accordance with the standard DIN 53752. The maximum allowable expansion of the cellular polycarbonate should not exceed 3 mm per 1 m, both in length and the width of the sheet. As the polycarbonate can be seen, it has a significant thermal expansion, which is why when it is installed, it is necessary to leave the appropriate gaps.

Change the linear dimensions of the cellular polycarbonate depending on the ambient temperature.

Chemical resistance material

The panels used for finishing are exposed to a wide variety of destructive factors. Cellular polycarbonate is highly resistant to most chemical inert substances and connections.

1. Cement mixtures and concrete.

2. PVC plasticized.

3. Insecticidal aerosols.

4. Powerful detergents.

5. Sealants based on ammonia, alkalis and acetic acid.

6. Halogen and aromatic solvents.

7. Methyl alcohol solutions.

Polycarbonate has high chemical resistance to the following connections:

1. Concentrated mineral acids.

2. Salt solutions with neutral and acid reaction.

3. Most types of reducing agents and oxidizing agents.

4. Alcohol solutions, with the exception of methanol.

When installing sheets, silicone sealants should be applied and the sealing elements of the EPDM type and analogues specifically designed for them.

Mechanical strength of cellular polycarbonate

Panels due to cellular structure are able to withstand significant loads. At the same time, the leaf surface is subject to abrasive exposure with long-term contact with small particles of the type of sand. It is possible to form scratches when contacting with rough materials of sufficient hardness.

Indicators of the mechanical strength of polycarbonate are largely dependent on the brand and structure of the material.

In the process of testing the panel showed the following results:

Checking the cellular polycarbonate in terms of strength indicators is carried out in accordance with the ISO 9001: 9002 standard. The manufacturer guarantees the preservation of operational characteristics for at least five years, provided that the sheets and the use of special fasteners are properly installed.

Sheet thickness and specific weight

Production technology provides the possibility of manufacturing a cellular polycarbonate of different sizes. Currently, the industry produces panels with a thickness of 4, 6, 8, 10, 16, 20 and 25 mm with different internal panel structures. The polycarbonate density is 1.2 kg / m 3, determined by the measurement method provided by the DIN 53479 standard.

Resistance of cellular polycarbonate to ultraviolet radiation

Characteristics of cellular polycarbonate are able to ensure reliable protection against ill-radiation in the UV range. To achieve such an effect in the process of production on the surface of the sheet by the method of coextrusion, a layer of a special stabilizing coating is applied. Dana technology is guaranteed to provide a minimum life of the material for 10 years.

At the same time, the detachment of the protective coating during operation does not occur due to the fusion of the polymer with the basis. When installing the sheet, it should be carefully inspecting the labeling and correctly orient it. Coating to protect against ultraviolet radiation should be drawn out. The light panel depends on its color and for unpainted sheets this indicator is from 83% to 90%. Transparent colored panels are missing no more than 65%, while polycarbonate disperses the light through them perfectly through them.

Thermal insulation properties of cellular polycarbonate

Cellular polycarbonate has very decent thermal insulation characteristics. Moreover, the heat resistance of this material is achieved not only due to the fact that inside it contains air, but also because the material itself has a large thermal resistance than glass or PMMA is the same thickness. The coefficient of heat transfer, which characterizes the thermal insulation properties of the material depends on the thickness and structure of the sheet. It varies within 4.1 W / (m² · k) (for 4 mm) to 1.4 W / (m² · k) (for 32 mm). Cellular polycarbonate is the most acceptable material, where it is necessary to combine transparency and high thermal insulation. That is why this material has become such popular in the production of greenhouses.

Polycarbonate industrial greenhouse.

Fire characteristics

Cellular polycarbonate is distinguished by high-temperature exposure. This material refers to the category B1, which is characterized by a European classification as self-fighting and refined. When combustion, polycarbonate does not highlight gases toxic and dangerous for humans and animals.

Under the influence of high temperature and open flame, the structure and the formation of through holes occurs. The material is significantly reduced by area and removed from the heating source. The appearance of the holes ensures the removal of the fire and excess heat fire from the fire.

Lifetime

Cellular polycarbonate manufacturers guarantee the maintenance of the main technical characteristics of the material for the service life of up to 10 years, subject to the milt and care rules. The outer surface of the sheet has a special coating, providing protection against ultraviolet. His damage significantly reduces the service life of the panel and leads to its premature destruction.

Noise insulation

The cellular structure of polycarbonate contributes to the low acoustic permeability of the material. Panels have pronounced insulating properties that directly depend on the type of sheet and its inner structure. Multilayer cellular polycarbonate thickness 16mm and more ensures the fading of sound waves in the range of 10-21 dB.

Moisture resistance

This sheet material does not pass and does not absorb moisture, which makes it indispensable when conducting roofing work. The main complexity in the interaction of cellular polycarbonate with water is to penetrate the inside of the panel. It is almost impossible to remove it without dismantling designs.

Long-term foundation of moisture in cells can cause its blooming and gradual destruction.

In order to exclude such a development of events in the installation process, only special fasteners with sealing elements should be applied. The edges of polycarbonate are covered with a special tape. The easiest way to clean the honeycombs are purging with compressed air from a cylinder or compressor.

To protect the edge from moisture, it is used: 1. - Special adhesive tape, 2. - Special profile that hoves on top of the glued ribbon.

Color range of panels

Cellular polycarbonate is supplied to the market in transparent and painted versions.

Manufacturers offer the customer in the following colors:

There is also a completely opaque variant of the silver shade panels. The transmissibility of cellular polycarbonate depends on its thickness and its internal structure. For a transparent material, light source is from 86% for 4 mm leaf, up to 82% for 16 mm of material. The staining of the material is carried out in the array, which helps to preserve the color during the entire period of operation.

Appointment and scope of material

Cellular polycarbonate is mainly used in construction to build roofs and enclosing structures.

This material, due to its exceptional properties, is increasingly used for the manufacture of the following elements:

1. Arched structures

2. Sheds over the entrance doors

3. Stopping public transport

4. Sheds for cars

5. Screens soundproofing along the railway tracks and high-speed highway

In private households, such panels are used for glazing veranda, attic, arbors or summer kitchens. Another scope of the application of panels is the production of agricultural greenhouses, which differ in durability.

Mounting complexity of cellular polycarbonate

The installation of a cellular polycarbonate is carried out by mounting on a frame from a steel or aluminum profile. It is allowed to bending the sheets across the ribs of stiffness, this property is widely used in the manufacture of visors and roofs. The minimum rounding radius of the panel depends on its thickness in the inverse addiction. Cellular polycarbonate 25 mm thick is not bent.

When making installation, you must perform a number of rules:

1. Cutting panels with a thickness of up to 10 mm is carried out with a sharp knife, saw with small teeth

2. Drilling is performed by a drill minimum distance from the edge of at least 40 mm

3. Panels are attached to the frame using self-tapping screws with sealing washers.

4. Separate sheets are connected with each other with special connecting elements.
