By parameters, photos, cost.

One of the main properties of polyethylene is its density. In solid polyethylene, it is approximately 940-960 g / m3. Such high is achieved by polymerization with system catalysts. Such material is called polyethylene high pressure. This is a hard thermoplastic, which is used in injection molding and blown molding.

The main properties of this class of polyethylene should include good chemical resistance, minimal water absorption, good extensibility, elasticity and resistance to temperature drops in the range from -70 to +100 degrees. The material is easily recycled and welded very well.

From high density polyethylene film make bags for non-food products, pipes for C / h work, packaging material. In particular, filling packages make stacking bags, bags with cutting handle, garbage bags, air-bubble film.

In everyday life, the product is used in the construction of greenhouses, summer cafes and soul (for such objects, a color opaque film is used). It is characteristic that when exposed to high pressure film, it is easily applied to various surfaces - Cardboard, paper, foil, etc. Surfaces on which PVD are applied, moisture resistant and waterproof are quite strong.

PND polyethylene films have good electrical insulating qualities (in some varieties of film, electrical density reaches 150kV / mm). With an increase in film density, such quality parameters as durability, rigidity, chemical stability increases. Thus, it can be concluded that high polyethylene film density Provides a number of useful qualities. If you need such a film, please contact Lentapak.

Low polyethylene density in the form of a film

Today, one of the most popular materials among customers - polyethylene low density. As is known, low is determined by the number of branches per 100 carbon atoms. The level of crystallinity of molecules is 50-70%.

The temperature softening of low density film is significantly less than the temperature of boiling water. Therefore, this type of film cannot be used in conjunction with hot water or steam. Low density polyethylene is distinguished by plasticity, mattness. Its density fluctuates in the range of 0.915 - 0.936 g / cm3. Films of this type are easy to weld heat welding, they form strong seams. It is possible to glue the film using tape and adhesives from half a bull. On the material after pre-training It is possible to apply print.

Film coatings with low pressure are quite well tolerated, resistant to loads on the gap and stretching. Different with resistance and temperature differences (from -50 to +10 degrees). Waterproof films, however, have a weak resistance to oxidation, so unsuitable for packaging of certain types of products. Good chemical resistance at low fat and oil resistance slightly limits the contact of this type of film with defined fluids.

Low density polyethylene is often used in the manufacture of packages, wrapping packaging, bags. In the manufacture of packages for the purchase is used, mainly film from 20 to 60 μm. A small density still does not mean that the film is continuing. The use of additives can significantly increase the strength of the products. For small capacity packages, a film is used to 10 microns thick. Thus, we see that polyethylene density in the form of a film It is one of the main parameters.

High density of polyethylene film kg M3 (PVD production)

High pressure film requires high pressure modern methods Her production. The manufacture of polyethylene film takes place in extruders. Necessary polyethylene film density (kg / m3) It is achieved by adding granular and in the form of high-pressure polyethylene powder. Next, the viscous mass is blowing out of the extruder on a special receiver. The film has a circular and flat cross section.

Highlights of production

Polyethylene granules fall into the receiving bunker. Special additives are used to increase the properties of the material. Next, the polymer falls on the surface of the auger. In the course of the rotation of the auger, the material begins to heat and melt. As soon as the alloy becomes homogeneous, it is extruded. After passing the head, the product is obtained by the desired form.

To get the sleeves, the blank must pass through a special slot and swell to of the desired size. The diameter and thickness of the sleeve can be adjusted by specifying the amount of air supplied. The canvas turns out of the sleeve - cutting it directly from both sides, half a bowl - with one. The resulting sleeve must be cooled and then go through the reception device, after which the film is wounded into rolls.

All stages are carefully controlled. In particular, you need to monitor temperature and pressure, as well as color (if color film is made). A high-quality film provides a uniform thickness throughout the area of \u200b\u200bthe canvas, the "correct" color, the absence of folds and chances, smooth and dense winding.

How to determine the thickness of the film for the greenhouse

The main indicator when choosing a greenhouse film is a density calculated in microns (microns). What are them less, the point in thinner, respectively below and its value.

But sometimes the sellers are custody, setting next to the "greenhouse" tights with large numbers. So, the option is very common when the "thickness" 120 μm is sold at the price of "thickness" 150 μm.

Unfortunately, to the touch, the forgery does not reveal: the density of the greenhouse film is determined only with the help of a special device - micrometer. But there is a way out of the situation. It is necessary to relate weight with a honey.

1 mm contains how much μm

The traffic point meter of the film with a density of 80 microns should weigh 210 grams, a density of 100 μm - 260 grams, a density of 120 μm - 320 g, 150 μm - 400 g, 200 μm - 530 g. (Calculations are presented on a standard one-year-old width, sleeve .

Let's consider. If you, for example, buy ten ramp meters with a "declared" density of 150 μm, the total purchase weight should be equal to four kilograms (10x400 \u003d 4000g).

micron (MKM)

In 1879-1967, the name was officially used micron (MK, μ), which was then canceled by the decision of the XIII General Conference on Measures and Sighs (1967/68).

Prefix Micro, serving in SI for the formation of dollars, adopted by the XI General Conference on measures and weights in 1960 simultaneously with the adoption of SI as a whole.

Application

The micrometer is a standard unit of measurement, which expresses deviations from the specified size ( according to GOST.) In engineering and almost any production, where exceptional size accuracy is required. In micrometers, the wavelength of infrared radiation is also measured.

For a better presentation of this unit of length, the following examples can be given:

micrometer, or micron (Russian Mark. μm., International - ICM) - measurement of the length of the unit in the international system of units (SI).

The micrometer is one million meters or thousands of millimeters: 1 μm \u003d 10-6 m \u003d 10-3 mm.

The name "MicroMeter" comes from the Greek word μικρός - "Small" and έέτρον - "Measurement", "Measurement".

In the period from 1879 to 1967, the name "Micron" was officially used (μ, μ), and then it was revoked by the XIII General Conference on Websis and Measures.

Some facts:

• a person can detect light waves from 0.38 to 0.78 microns;
• the erythrocyte diameter is 7 microns;
• The thickness of the human hair ranges from 80 to 110 microns.

For machine construction requiring exceptional size accuracy, the micrometer is a standard deviation for deviations from a certain size.

The micrometer is used to measure the wavelength of infrared radiation.

Nowadays, unscrupulous manufacturers can artificially overstate the density of garbage bags, but they are quite easy to remove clean water. For this you need simple tools And our table for calculating the proper weight of the bag with its declared density seller.

Let's figure out what microns is and why it is so important.

What is micronism in packages

You have repeated ever why packages for garbage of one manufacturer proceed and rush, while the other is withstanding heavy loads and tension, but remain as durable and integers. All this is due to a different density bag: how much the manufacturer will spend the material as far as the polyethylene will stretch - such strength at the package will. But what does this density measured? In Milmeters? In grams per billime? In what degree?

So, to determine the thickness there is a parameter - microns (MKM).

What is Micron?

Micron (MK, μ, μm, μm) is a measurement unit adopted for 10 -6 meters (1 μm \u003d 0.001 mm \u003d 0.0001 cm \u003d 0.000001 m).

Why do you need to know the micronism of the package?

The microns (thickness) of the PND packages and the PVD will make it possible to accurately determine which load is able to withstand the package, its carrying capacity.

What's wrong with garbage bags

Today they produce garbage bags by microns from 4 microns and above. Some manufacturers indicate the density indicator on the labels of their products, but it rarely reflects the real thickness of the package. In order to accurately determine the thickness of the goods, we offer an accurate standard definition of micronism of garbage bags from PND and PVD, which is calculated based on four parameters:

• Weight.
• Density.
• Square (length, width).
• Cefficient for the type of raw material.

The micronism indicator is important when we exactly want to find out which load packages are calculated. The lower the indicator, the smaller the load package can endure, and, on the contrary, the higher the microns, the higher its carrying capacity.

How to independently determine the density of the bag

You will need the following things:

• Rubbish bag.
• Kitchen scales.
• Line.

Measure the width and height of the bag, write it down in our formula. Specify the density of the salar bag - the density is measured in micrometers (microns). Submire the resulting values \u200b\u200bin our calculation table and check the resulting weight.

Now compactly fold the bag and weigh it on domestic scales. If the seller is a good, then the resulting value in the formula will not differ from the value on the scales.

You can use our formula to determine the weight:

Formally, the abolished metric unit is equal to 10 -6 (one million) meter. Designation μ. The name and designation were adopted in 1879 by the International Committee of Measures and Scales (CIPM) and re-approved by resolution 7 at the 9th General Conference on Measures and Weighs (CGPM) in 1948. In 1967, the 13th CGPM conference abolished the unit "Micron" (resolution 7) and recommended the use of the term "micrometer" instead. For this unit of length in the system, the term "micrometer" (μm, μm designation) is adopted. Nevertheless, the term "micron" continues to be widely used in some areas, including in the production of semiconductors. This term is often used to describe the particle size delayed by air and water filters, wavelength ranges to which optical instruments react, as well as in mechanical processing. One of the applications where the use of this unit is currently legalized state standards, This is a description of the quality of wool and other textile goods (see www.ymccoll.com/micron_reports.html).

Micron is often found in the composition of the word Millimikron \u003d 10 -9 meter or 1/1000 share of the micron. Designation Mμ. Like Micron, Millimikron is an outdated unit. Modern unit System systems having the same value is a nanometer (NM, NM designation).
