2. Procedure for the production of work

Anti-corrosion protection works should be carried out in accordance with the normative and technical documentation.

Preparatory work: placement and installation of the necessary materials, equipment and tooling.

Preparation of surfaces to be painted with ZINOTAN:

• elimination of surface defects;
• removal of oil and grease contamination;
• abrasive blasting from oxides (scale and rust), old paint;
• removal of dust and abrasive residues.

Staining with the composition ZINOTAN:

• preparation of the composition ZINOTAN for work;
• applying the composition;
• drying;
• quality control and acceptance of ZINOTAN coating.

Coating operations:

• preparation of covering paints and varnishes (POLYTON-UR and POLYTON-UR (UV) enamels) for work;
• application of coating paints and varnishes;
• drying the coating;
• quality control and acceptance of the coating.

Metal surface preparation

Before applying the ZINOTAN primer, surface defects (sharp edges, burrs, welding spatter, etc.) must be removed from the surface of metal structures; sharp free edges to be primed may be blunt with a 2 × 2 mm chamfer with rounding of the corners; the surface must be free from dirt, dust, grease stains, rust and scale.

Particular attention should be paid to cleaning bolted joints, sinks, pockmarks and hard-to-reach areas.

Welded seams must comply with GOST 23118, must be solid and continuous (continuous) without pores, cracks and breaks. The shape of the weld should be smooth, with a smooth transition from the bead of the weld to the metal.

Clean structures from peeling scale, dirt, layers of old paint with a spatula or hand tool.

Degrease metal structures to the first degree in accordance with GOST 9.402, using white spirit (in accordance with GOST 3134) or solvents of grades 646, 648 (in accordance with GOST 18188). Degreasing operations should be performed prior to abrasive blast preparation of the surface.

Degreasing is allowed to be carried out by jet washing, a brush, a soft hair brush or a lint-free cleaning material (rags). After degreasing, dry the surface clean air by ventilation until the solvent vapors are completely removed.

The surface of metal structures should be cleaned of oxides (scale and rust) and old paint by abrasive blasting to grade 2 in accordance with GOST 9.402 or Sa 2 1/2 (in hard-to-reach places- Sa 2) according to ISO 8501-1, using an abrasive with a particle size that ensures the required surface cleanliness and roughness. The abrasive material shall comply with the requirements of ISO 11126.

The surface after abrasive blast cleaning to Sa 2 ½ according to ISO 8501-1, when viewed with the naked eye, must be free of scale, rust, burn-on and other non-metallic layers. Different shades of the cleaned surface are allowed from light gray to dark gray caused by different surface roughness of metal structures.

Optimal surface roughness Rz from 30 to 50 microns in accordance with GOST 2789; according to ISO 8503-1 - thin (Comparator type G - between segments 1 and 2, but lower than segment 2).

Before cleaning, check the presence of moisture and oil in the supplied air - compressed air must comply with the requirements of GOST 9.010 (compressed air group 2).

The quality of air purification is checked by directing a stream of compressed air from a nozzle onto a sheet of filter paper. Air purity is considered sufficient if no traces of oil and moisture remain on the paper after blowing for 10-15 minutes. If the air purification is not satisfactory, the filter gasket of the oil-moisture separator must be replaced.

Dust the surface after cleaning by blowing dry, clean compressed air. The degree of dedusting of the surface should be no more than 2, with a particle size of no more than class 2 (ISO 8502-3 "Evaluation of dustiness of steel surfaces prepared for paint application (Adhesive tape method)").

In the case of an increased likelihood of the presence of pollutants on the surface under the conditions of a construction site, operations should be carried out to control the presence of soluble iron corrosion products in accordance with ISO 8502-1 and chloride contamination in accordance with ISO 8502-6, ISO 8502-9 (before and after washing with water, as well as before and after abrasive blasting). The maximum content of water-soluble salts and

impurities on the surface should not exceed the conductivity value corresponding to the NaCl content of 20 mg / m2.

The interval between cleaning the surface and painting it on outdoors in the absence of moisture condensation on the surface and the exclusion of any kind of contamination should be no more than 6 hours. It is allowed to increase the duration of the break to 24 hours while maintaining the quality of the prepared surface.

Enamels POLYTON-UR and POLITON-UR (UV) should be applied on a clean, free from dust and grease contamination, dry surface of coatings ZINOTAN and POLYTON-UR, respectively.

The procedure for painting work

Conditions for carrying out painting works

When carrying out painting work, it is necessary to control the environmental conditions (temperature and relative humidity, wind speed).

In the conditions of the construction site, painting work should be carried out in the absence of precipitation in calm weather (at a wind speed of more than 10 m / s, painting work is prohibited). The temperature of the surface to be painted must be at least 3 ° C above the dew point (Appendix B).

Composition ZINOTAN and POLYTON-UR enamel may be applied at ambient temperatures from minus 15 to plus 40 ° С and relative humidity from 30 to 98%.

Enamel POLYTON-UR (UV) should be applied at an ambient temperature of + 5 to + 40 ° C and a relative humidity of no more than 85%.

When carrying out painting works in conditions of low temperature, paint and varnish materials, as well as all equipment, including hoses, spray guns, etc., must first be kept for 24 hours in a warm room with a temperature of at least plus 15 ° C.

When storing paints and varnishes in freezing temperatures, it is recommended to keep them in a closed heated room for 24 hours before applying.

It is forbidden to paint surfaces covered with frost and ice.

The drying time of one-packing polyurethane materials ZINOTAN and POLYTON-UR depends on the relative humidity of the ambient air and decreases with its increase.

The drying time of POLYTON-UR (UV) enamel depends on the ambient temperature, and when it rises, it decreases

For painting large-sized structures, use the method airless spray... Before applying the material, it is necessary to strip paint hard-to-reach places (bolted joints, welds, etc.) with a hair brush with a short thick bristle.

Parameters for airless spray application:

a) spray pressure: 10 - 20 MPa (100 - 200 bar); b) nozzle diameter:

1) for the composition ZINOTAN - 0.015´´ - 0.021´´ (0.38 - 0.53 mm);

2) for POLYTON - UR enamel - 0.013´´- 0.021´´ (0.33 - 0.53 mm);

3) for POLYTON - UR (UV) enamel - 0.011´´ - 0.015´´ (0.28 - 0.38 mm);

c) the angle of the spray when spraying - depending on the configuration of the surface to be painted: for structures with a width of up to 100 mm - 20 °; for structures with a width of 100 to 350 mm - from 40 to 60 °; for structures with a width of more than 350 mm - 80 °;

When working with airless spraying devices (APR), it is necessary to follow the instructions for their operation and maintenance. Before starting painting, to clean the equipment from previously used paints and varnishes, the SOLV-UR solvent (TU 2319-032-12288779) or (additionally for POLYTON-UR (UV) enamel) - oil solvent (GOST 10214) should be passed through the paint sprayer.

At the end of the work, all equipment and equipment for the application and preparation of materials should be washed with a solvent. To flush the painting equipment from the applied paints and varnishes, you should use SOLV-UR solvents, petroleum solvent; additionally for the composition ZINOTAN and POLYTON-UR enamel - solvents of the R-4, 646, 647 brands.

General requirements for painting work

When working with one-packing polyurethane paints and varnishes (ZINOTAN, POLYTON-UR), it is necessary to take measures to reduce their contact with air in containers:

- during breaks in work, the container with the material should be tightly closed with a lid;

- use the material in an opened container during the work shift; in case of incomplete use, the working composition remaining in the container should be poured with a thin layer of SOLV-UR solvent and the container should be tightly closed with a lid.

When carrying out painting work, the following requirements must be taken into account:

- the spray gun should be positioned perpendicular to the surface to be painted at a distance of 200 - 400 mm;

- when painting, do not allow gaps, drips;

- the overlapping of paint zones on the previously applied coating must be at least 200 mm.

The coating should be applied in an even layer. In the process of work, it is necessary to visually control the continuity of the coating for the presence of unpainted areas, the number of layers and the thickness of the wet layer using an uncured layer thickness gauge (“comb”) in accordance with ISO 2808 (method 1). The thickness of the wet layer is worked out by the painter when mastering the technology.

The adhesion control of the coating should be carried out by the cross-cut method according to GOST 15140 (method 2), by the cross-cut method according to ISO 2409 or by the X-shaped cut method according to ISO 16276.

Full curing of the coating for use (a set of physical and mechanical properties) occurs within 7 days (at an ambient temperature of plus 20 ° C) after applying the finishing layer (POLYTON-UR (UV) enamel).

6. Scheme of operational quality control

Construction control should be carried out by the construction control units of the CCC at all stages of the implementation of all types of construction and installation work. It is prohibited to carry out construction and installation works without the participation of the CCM. The contractor is responsible for the organization and quality of construction control.

The CCM must carry out construction control in the course of each technological stage of work. The results of the construction control are recorded daily in the construction control log of the contractor at the work site, the general log of work and the log of comments and suggestions. The construction control log of the contractor is drawn up in accordance with Appendix B OR-91.200.00-KTN-108-16.

A typical technological map for painting the facade with a spray gun is developed in order to streamline the entire chain of work performed when covering wall surfaces with silicate compounds. Walls are treated with these substances not only in industrial and civil buildings, but in the production of repairs in private housing.

These documents necessarily contain sections related to labor protection and quality control of work performed.

Determination of the routing

Silicate coatings contain minimal components. Due to this, they have excellent performance properties, such as vapor permeability, resistance to atmospheric precipitation. They also do not pose a threat to the environment. These materials are sold ready-made and have excellent resistance to various chemicals. Due to their resistance to atmospheric phenomena, the compositions are successfully used for outdoor facade works related to the restoration of architectural objects of artistic heritage.

The technological map for covering facades with materials resistant to the atmosphere should contain the entire range of work carried out to optimize the production process, bring it in accordance with regulations, reduce costs, and adjust production times.

This document includes information that spells out the basic requirements for the quality of the material, its proper storage, and transportation. The main section concerns the arrangement of the workplace in accordance with SNiP, correct and safe methods of work at height, the required mechanisms and tools are listed. Particular attention is paid to the safety of work.

These documents are developed by the production and technical department in the organization and are intended for section managers and foremen. These specialists are obliged to study in detail all technical documentation and organize the labor process of workers in accordance with the requirements specified in the technological maps. Engineering and technical specialists are personally responsible for the safety of the work process.

Application area

The technological map was drawn up to cover the enclosing surfaces with special paints and varnishes that are resistant to atmospheric precipitation. This document applies to the construction of the rear, carrying out renovation works, for the reconstruction of the facades of various objects.

Before starting work on painting buildings, it is necessary to carry out the entire set of measures to prepare wall surfaces for final painting. These works may include capital or partial renovation all outside walls. A prerequisite is the assessment of the state of the object by certified experts.

Finishing work is possible only with special permits. One of them is the color passport for the object, which is issued by the relevant government agencies.

A typical WPS can be linked to the correct building object. At the same time, it is necessary to coordinate the work schedule, volumes and costing.

Surface preparation

Facades intended for painting must have a surface moisture content of more than 10%. For work on painting street walls, according to SNiP, certain requirements... Outside air temperature should not be lower than 12 ° C, relative humidity - above 85%.

The requirements for the preparation of the enclosing surfaces are different. Each type of surface has its own characteristics in preparation for painting.

Monolithic concrete painting

Monolithic concrete, as a rule, has shells and cracks on its surface. These defects are overwritten with special plaster compounds. Defects in the base are filled with these materials and then leveled with a trowel. During the production of work, it is necessary to ensure that the surfaces do not dry out, which can lead to negative consequences, such as the formation of cracks and delamination of the material.

For this type of work, it is advisable to use a dry mixture. This material is a powder based on high grades of cement and various additives.

To eliminate small flaws in the concrete surface, special dry mixtures are used that contain mineral particles. They have excellent performance properties, such as resistance to negative temperatures, good adhesion.

Before applying this composition, the enclosing surface is cleaned of dust, dirt, old paint residues, and other foreign objects and substances. These inclusions can reduce the quality of the application of the material. The finished mortar is laid with a special spatula, after which it is rubbed with a float to give the wall a smooth surface. If the work is carried out correctly, the consumption of the mixture should not exceed 2 kg / m² with a thickness of no more than 1.5 mm.

The concrete surface, depending on the method of its production, can be dense or porous. Different grouting materials are used for different surfaces.

For a porous concrete surface, light mixtures are used, they are also called shallow ones.
Before applying any formulations, the surface should be double primed with a break in work for 24 hours. The primer is diluted before application to the surface clean water in a 1: 1 ratio.

Consumption of the primer should not exceed 0.3 kg for each coating layer.

Painting plastered surfaces

After applying the new plastering compound, the surface must be painted after four weeks after the completion of the work.

When repairing an old plaster composition, it is necessary to first remove all fragile elements and enlarge the cracks by removing crumbling fragments of the old coating. After that, large areas are restored with a special composition based on lime. This material is made from cement, various lime additives and mineral additives, it is absolutely not hazardous to human health, and besides, it adheres well to the surface.
Prepared cracks and cracks with the help of special devices are filled with the ready-made mixture. This field is followed by a technological break, necessary for the mixture to set a little, and then it must be rubbed with a spatula. Finished repaired areas must be allowed to stand for at least 8 days.

After the enclosing structure is leveled, it must be covered with putty. For this, a dry mixture is used, which, in addition to cement, includes special additives.

When applying this material, use special spatulas... Application thickness should not exceed 4 mm. Ideally, the plaster layer should be visible through the applied putty. If the work is carried out correctly, the consumption of this material should not exceed 1.5 kg per 1 m² of coverage.

The next step is the final leveling of the surface. For this, grinders of various designs are used.

Surfaces plastered with decorative compounds

Decorative plaster is usually called terrazzite. Repair of such a coating is made only with a similar material. This substance also contains lime particles, crumbs of various rocks and special hydraulic additives.

Plastering of buildings that are architectural monuments is carried out only with special powder plasters, which have a high content of lime components.

Repair brick walls, the filling of the holes due to the absence of separate silicate blocks is carried out with a special cement-lime composition specially designed for this. Before starting work, the brickwork is covered with a primer. After a 24-hour technological break, a secondary coating is made. Soil compositions are diluted with clean water in a 1: 1 ratio.

The repair of the red brick enclosing structure is carried out with exactly the same plaster mortar with a double primer coating and with a 24-hour break in the work performed.

Painted facades

When renovating painted facades, preparatory processes are necessary. All old coatings must be removed from the surface of the building envelope. Old paints and varnishes are washed off with clean water. Before coating the facade with paint, it must be fully primed.

Painting the facade is the final stage in the restoration of the building. Before it, all work on the roof, balconies should be completed, blind areas of buildings should be arranged, window slopes should be completed on a turnkey basis. Also, all fastening elements installed on the facade for fixing various engineering communication systems on it must be mounted. The brickwork was repaired, all cracks were repaired with appropriate mortars. The installed elements on the facade, which cannot be painted, are neatly packed with plastic wrap in at least two layers.

Materials for surface priming are produced in 15 and 20 kg in special containers. Plaster mixes, as a rule, are sold by the manufacturer in special packages and packaged in 20 and 25 kg. Paints and varnishes with silicate compositions are sold in the retail network ready-made in plastic buckets of 10 and 20 kg.

Facade painting

Surfaces prepared for painting must be dry, clean, even, treated with a primer. According to the requirements of regulatory documents, it is prohibited to paint facades under the following weather conditions:

• during rain, if the surface is wet and not dry;
• with direct sunlight on the facade and in hot weather;
• if the outside air temperature is less than 20 ° С;
• in strong winds.

The next step is to agree colors with the customer. This process can take several days to match the desired color. After agreement, you can start painting the surface.

For painting, it is advisable to use silicate paints and varnishes. When working with serious volumes, you will have to order a large amount of paint. Since this material is packaged in containers of 20 kg, it is possible for the object to receive paint from different batches. In this regard, a situation may occur when the paint and varnish material in different batches of the same color has different shades. To prevent this problem, it is best to pour the entire composition entering the site into one large, clean container and mix.

Before you start painting the surface, if necessary, the solution must be brought to the desired consistency. To do this, add a special primer of a similar composition to it. When mixing, it is necessary to be guided by certain rules specified in the technological map. The amount of primer added should not exceed 10% of the total paint volume.

Painting, according to SNiP, should be done in at least 2 layers. Secondary surface coating facade paints carried out after the first layer has completely dried. In dry weather, this takes about 6-8 hours.

To obtain a high-quality surface, the paint and varnish composition should be applied in an even layer of the same thickness.

With proper preparation of the surface before painting and observing the production technology, the consumption of paint material should not exceed 0.3 kg per 1 m2 when working with the first layer and 0.15 - when re-painting.

For painting, you can use special spray devices. Painting the facade with a spray gun is carried out in accordance with the following rules:

1. The speed of movement of the device must be uniform, without acceleration and deceleration. It should be approximately 15 m / min.
2. Sprayed stripes should overlap by a quarter of their width.
3. When working with the use of painting mechanisms, window openings, blind areas, all parts of the facade that are not intended for applying paint are packed in plastic wrap at least 2 layers.
4. For the smooth operation of the painting equipment, a constant air pressure in the system of at least 5-6 atmospheres is required.
5. During the coloring process, the directions of particle flows should be mutually perpendicular.
6. Depending on the setting of the nozzle of the device, the spray gun is kept from the surface at a distance of about 400 mm.

How to choose paint

The choice of paint to a common man in the street will seem a very easy task. Meanwhile, the building envelopes are built from variety of materials that have different properties. Facades are covered with different putties and primers, not all paint and varnish coatings are compatible with these materials.

Additionally, you need to pay attention to the composition of the paints. This factor greatly affects the durability of the coating.

Currently, oil paints and varnishes are widespread. But, unfortunately, they have insufficient performance characteristics. More than suitable option facade colors are water-based compositions. These paints have very good resistance to environmental processes and are best suited for façade work. Another advantage of these compounds is their incombustibility. Among the many varieties of these paints, I especially want to highlight silicone compositions. These substances combine the best properties of acrylic and silicate paints. The main advantage of these coatings is that they do not have an unpleasant odor. These compounds are quick-drying, which is a key factor in our climate.

Another type of water-based composition is alkyd paint. This paint has high performance and dries faster than oil paint.

There are also reactive compositions for painting facades. Their peculiarity is that they consist of two components. These compositions, with all their advantages, have disadvantages. They can be used only for one limited period of time specified in the accompanying documents for the paint. But the cost of these compounds is quite high.

Quality control

Acceptance of the quality of finishing works is carried out by the customer's service in accordance with the necessary regulatory documents.

The production quality control of work without fail includes the entrance, operational and acceptance control of the painted facade.

The first is to check the quality of materials received at the construction site, the presence of markings on the container, and operational properties. All substances must have declarations and appropriate certificates of the customs union on the quality of products.

Building materials used in finishing (and in general in any construction) work must necessarily comply with the requirements of GOST and technical specifications. To obtain a quality certificate, they are checked in special laboratories for compliance with the declared performance characteristics and properties.

Operational control is a procedure for monitoring the quality of painting in the course of work. It aims to timely identify defects and their immediate elimination directly in the process of construction production.

When preparing the base for coating with compounds, check how well the coating is prepared. It should be free of dust, dirt, rust, cracks, drips of working solutions.

The moisture content of the coating, the quality of the applied putty and primer are subject to verification.

When covering the facade with paint, the thickness of the applied layer is determined, the uniformity, the absence of stripes, drips, splashes, it turns out whether the work technology was followed.

Requirements for the safety of the work performed

According to regulatory documents for the safe performance of work, all workers must be equipped with personal protective equipment. For painting work, such products include: special clothing, footwear, respirators, protective masks. All workers, without exception, must have eye protection equipment and special gloves. These funds are necessary to prevent the ingress of hazardous substances into the natural cavities of a person and to protect his skin.

When carrying out facade work, other safety requirements must also be observed. This also applies to work at heights and the use of electrical, pneumatic, hydraulic and other construction equipment. Compliance with safety regulations guarantees the preservation of the life and health of citizens who work at the construction site.

17. The degree of manifestation of electrostatic affect, as well as the quality of the painted surface depend on the specific volumetric resistance, dielectric constant and viscosity of the paint and varnish material.

It is most rational to use paints and varnishes with the following characteristics:

• volumetric resistivity from 5x10 6 to 5x10 7 Ohm · cm;
• dielectric constant from 6 to 11 f / m;
• working viscosity according to the VE-4 viscometer no more than 30 s.

The volumetric resistivity is checked by the PUS device, the dielectric constant - by the E-4-4 figure of merit meter, the viscosity - by the VZ-4 viscometer.

18. The paint material must be filtered through a 05 brass mesh and checked.

19. When preparing the paint composition, it is necessary to be guided by the data in Table. 1.

22. Preparation of paints and varnishes, including dilution and control, should be carried out centrally for all working painting installations (posts). In this case, it is necessary to be guided by the methodology attached to the operational documentation of the UREG-1 installation.

23. It is prohibited to use nitrocellulose, perchlorovinyl, water-borne and hammer enamels for painting products in an electrostatic field, as well as paints and varnishes and solvents, the composition and properties of which are unknown.

24. Preparation of the manual electrostatic installation UREG-1 is carried out before starting work in order to ensure uninterrupted operation.

25. To prepare the electrostatic installation for operation, it is necessary:

• check the integrity and cleanliness of the means of mechanization;
• ground the UREG-1 unit;
• connect the power cord of the unit to the 220 V AC network;
• attach the compressed air supply hoses to the spray gun and secure them with a clamp;
• connect material hoses to the spray tank and spray gun;
• install air pressure regulators and paint within the required limits;
• fill the paint injection tank with a painting compound;
• check for electrostatic charge by test painting.

26. Detailed information on the preparation of mechanization equipment for operation and maintenance of the installation is contained in the "Technical description and operating instructions for the installation for manual electric painting UREG-1" and the section "Methods and techniques of work" of this technological map.

27. It is forbidden to work with an ungrounded electrostatic installation UREG-1, as well as in the absence of the phenomenon of circular coverage of metal structures with a paint composition.

28. Work on painting metal structures using a manual electrostatic installation UREG-1 is carried out according to the following technology: surface priming; application of the paint composition.

29. When painting metal structures, one or several manual electrostatic installations UREG-1 can be used, depending on the places of painting (workshop for centralized painting or post-assembly painting).

30. Technological modes of painting depend on the complexity of the configuration of the products, the applied paint and varnish material, the current on the charger, the temperature and relative humidity of the air in the painting area.

31. The high quality of the coatings can be guaranteed if the technological regimes for the application of paints and varnishes are observed (Table 4).

Table 4

Technological modes of applying paints and varnishes

Oil paint MA-025, thick-grated whitewash
Colored thick grated oil paints on earth pigments (red lead iron)

32. In the process of work, having installed the UREG-1, the painting or primer composition from the spray tank under the action of compressed air enters the spray gun, where the compressed air for spraying is supplied. When you press the trigger of the spray gun with your finger, channels are opened through which the paint composition x air begins to move.

Under the action of the dynamic air pressure, a high voltage circuit (10-14 kV) is closed with the help of a pneumatic relay, in which the corona electrodes are located. The sprayed and electrically charged paint composition increases this charge in the flow of ionized air and settles on the grounded product to be painted.

33. The color of the painted metal structures must correspond to the project.

34. Painted surfaces should have a uniform texture. Translucence of underlying paint layers, as well as stains, splashes, bubbles, blockages, wrinkles, smudges, omissions, etc. not allowed.

35. After finishing the painting work, the spray tank, spray gun and the entire paint supply system must be flushed out. Flushing of the spray system is carried out after the end of each work shift.

36. It is forbidden to leave the UTEG-1 unit in a non-washed state and with a paint-heating tank filled with paint.

IV. METHODS AND METHODS OF LABOR

1. Work on the preparation and painting of metal structures with a manual electric paint installation UREG-1 is carried out by a team of two people

• painter (operator) 3 digits (М1) 1
• painter (operator) 4 digits (М2) 1

Means of mechanization are serviced by an electrician of the 4th category, working in the shop.

2. Organization of the workplace when painting metal structures depends on the painting conditions.

3. The layout of the workplace in the centralized painting shops at the stationary station is shown in Fig. 1.

4. The layout of the workplace when painting metal structures on the production line of centralized workshops is given in Fig. 2.

5. The layout of the workplace when painting metal structures in open areas is shown in Fig. 3.

6. Execution of work on the organization of the workplace real card and costing is not provided for, but is decided additionally in each specific case.

7. The technological process of staining with the help of a manual installation UREG-1 provides for a complex of technological operations that do not depend on organizational factors.

This complex includes operations for the preparation of metal structures, painting materials, installation and painting itself.

8. The calculation of labor costs and the schedule of the labor process are drawn up for painting 100 square meters of metal structures of medium complexity and are given in tables 5 and 6.

9. Time norms for individual technological operations are adopted according to ENiR, Sat. 8 with the introduction of coefficients reflecting additional costs, as well as based on the productivity of the UREG-1 installation.

10. Complex of operations: preparation of metal structures for painting, consisting in cleaning structures from dust, rust, scale, spray of solution, etc., are performed by painters M1 and M2. Clean surfaces from dust and dirt with a rag; from rust - with a wire brush or chemical means by applying them to the surface with a rag, brush or roller, followed by removal. After removing the rust, finally wipe the surface with a rag.

11. The preparation of working paint compositions is carried out by painters M1 and M2 in an amount that does not exceed the replacement requirement. At the same time, the primer and paint compositions are diluted to the desired viscosity, which is controlled by a VZ-4 viscometer, then the volume resistivity is determined by the PUS-1 device and the dielectric constant is determined with a Q-factor meter of the E-4-4 type, if necessary, they are corrected by introducing the required amount into the composition emulsifier OP-7. The finished composition is filtered into an injection tank through a semi-compact mesh 05.

12. The preparation of the UREG-1 electric paint unit is performed by painters M1 and M2. At the same time, by external examination, they are convinced that there is no damage to the installation elements; all handles on the panel are set to the "Off" position, if necessary, remove the preservative grease from the installation surfaces with a cloth soaked in solvent. Remove the plugs from the nozzles intended for connecting the sprayer, connect the sprayer hoses to the fittings according to the inscriptions, and the cable to the excitation unit, connect the unit to the compressed air network and the power supply network, ground the unit and products.

13. Check the operation of the agitator by turning the knob on the top cover of the agitator pneumatic motor by two turns, and then put the tap with the inscription "Agitator" in the "Open" position.

The frequency of switching on, the duration and intensity of the stirrer are set depending on the type of paint and varnish material.

If the air pressure in the network is 0.45-0.5 MPa, then for normal operation of the sprayer it is recommended to turn on the agitator during breaks in the operation of the sprayer.

14. Set the torch width required depending on the coloring of the products, for which the nozzle is removed from the sprayer and the diaphragm is placed in one of the positions marked with numbers on it.

15. Open the tap with the inscription "Air pressure", set the required spray pressure in the range of 0.45 - 0.6 MPa. Set the movable nut on the spray head in the position where the mark at its front end coincides with the mark on the union nut, on the first turn from the last, the marks on the movable nut correspond to the optimal sprayer operation: at the front end - at an air pressure in the network of 0.45 MPa, at the rear - at 0.6 MPa.

16. Set the "Generator Power" switch to the "Mains" position - the green light comes on, turn on the sprayer. In this case, a red light should light up, then, turning the "High voltage" knob on the control panel, set the current 75 + 100 μA by the microammeter.

17. Set the required paint pressure, but not more than 0.4 MPa, using a valve with the inscription "Paint pressure" and a regulator.

18. Confirm the presence of the affect of coverage by testing a grounded metal cylinder with a diameter of up to 100 mm without turning it. Best effect coverage is achieved by turning the movable nut on the spray head in the great-grandfathers of the zone indicated by the marks.

19. When drawing up a work schedule and calculating labor costs, it was taken into account the execution of the operation for the preparation of electro-paint equipment twice per shift (at the beginning of the shift and after the lunch break).

With a one-time preparation of the equipment, it is necessary to make adjustments to the table. 5 and 6.

20. Technological operations for applying primer and paint layers on the surface of metal structures using the UREG-1 installation are performed by painter M2; first he checks the position of the "Paint supply" and "Paint pressure" valves on the installation (they must be open), then takes the spray gun into right hand holding it with the left, while pressing the trigger, creates a torch of paint, directing it to the product to be painted.

21. When applying the primer and paint layers, the spray gun must be kept from the surface to be painted at a distance of 250-350 mm, since with an increase in this distance, the loss of paint and varnish material increases.

22. At the end of each shift or at the end of painting work, painter M2 pours paint from the spray tank and pours 3/4 l of solvent into it, connects the sleeves and closes the tank with a lid. Sets the "Paint supply" and "Paint pressure" taps to the "Open" position, opens the spray gun and, pouring the solvent into an arbitrary container, flushes the paint supply system until the traces of paint disappear. Then he wipes the surface of the sprayer with a cloth soaked in solvent.

23. When painting metal structures located higher than 3.5 m from the floor or ceiling mark, work must be performed from a mobile platform.

24. When calculating the time norm for painting metal surfaces, the work of the installation from the ground was taken into account, when working from the scaffold, the time norms and prices for priming and painting in table. 5 and 6 must be multiplied by a factor of 1.25 in accordance with ENiR, sb. 8, section III.

Target: To develop skills and abilities for painting the surfaces of walls and ceilings with lime compositions.

Tool

Instructions on how to get the job done

Preparation of lime paint composition

Capacity, construction mixer

Lime dough is diluted in 6 liters of water, table salt dissolved in 0.5 liters of water is added, and everything is mixed. Then add water to 10 l and get a white color. If a color tint is needed, then a pigment soaked in water is added to the white composition and mixed thoroughly. For staining, various coloring compositions or colors are prepared.

Surface priming

Brush

The surfaces are cleaned, moistened with water and primed. When preparing a lime primer with table salt, the lime dough is diluted in 5 liters of water and table salt dissolved in boiling water is added to this solution. With constant stirring, pour in water up to 10 liters. Lime dough consumption - 2.5 kg, salt - 0.1 kg.

Surface painting

Brush

Lime paint is used both outside and inside buildings to cover porous surfaces and plastered with lime mortars, brick walls, as well as to paint damp and cold rooms. Apply the composition with a brush. When painting with a brush, put two or three thin layers on the still wet previous layer.

It must be remembered that lime paint is usually applied with horizontal movements, and shading is done vertically.

Safety precautions.

Before starting work, it is necessary to undergo a safety briefing, put on overalls, inspect the workplace, check the correct placement of materials and the serviceability of tools, inventory, devices. The tool must be used for its intended purpose. When painting surfaces with lime compounds, the painter must use personal protective equipment - goggles, cotton or rubber gloves, and a respirator. All operations of the technological process must be carried out in compliance with the technical safety rules. When working, it is very important to choose the correct working position. This not only reduces fatigue, but also largely protects against injury of all kinds. After finishing work, clean the tool, clean the workplace, carry out personal hygiene.
