TECHNOLOGICAL MAP

PLASTERING AND PAINTING WORKS IN LARGE-PANEL HOUSES

I. APPLICATION AREA

The technological map was developed based on the application of methods scientific organization labor and is intended for use in developing a project for the production of work and the organization of work and labor at the site.

The map was compiled for plastering and painting work on a 60-apartment building of series 1-467 A-2 and can be used when performing plastering and painting work in large-panel buildings of other types.

II. INSTRUCTIONS FOR WORK TECHNOLOGY

A) Plastering works

1. Plastering work is carried out first on the 1st floor, then on the 2nd, 3rd and subsequent floors with transitions within the floor from one section to another. Plastering work is carried out in those sections where structures are not being installed.

Before plastering begins, brick and concrete surfaces are thoroughly cleaned of dust.

2. Support tables under the entrance canopies and niches above the canopies are plastered according to metal mesh with cell size 10×10 mm or by weaving from wire with cells no larger than 40×40 mm . Skirting boards, platbands and door frames are coated with a solution and the surface is smoothed.

3. When covering the walls and ceilings in the vestibule with sheets of dry plaster over insulation, the sheets are attached to wooden blocks with thin nails (tar paper) with wide heads. The nail heads are sunk into the sheets and puttyed.

4. When cutting rust patterns on ceilings with a template, the grooves at the joints of the slabs are thoroughly cleaned of dust and abundantly moistened with water, and then filled with cement mortar to the full depth and smoothed.

To speed up the setting of the cement mortar, about 1-2% gypsum is added to it with thorough mixing of the mixture.

5. Due to the small volume, plastering work must be done manually.

6. In winter, plastering work begins after completion of installation, roofing and glass work. The air temperature inside the building must be at least +8 °C (when measured at a height of 0.5 m from the floor).

7. Window sills should be plastered before the onset of cold weather. When plastering them in winter, it is necessary to protect the plaster markings from premature freezing by electrical heating, insulation with felt, etc.

8. Plastering work is performed from strong, stable scaffolds or tables. Moreover, you can only work in one height tier at a time.

9. Workers performing work must comply with the requirements of SNiP III - B .13-62 “Finishing coatings for building structures. Rules for production and acceptance of work" and safety rules in accordance with SNiP III-A

b) Painting work

1. Before starting painting work in the premises to be finished, all general construction, electrical and plumbing work, as well as glazed window sashes and balcony doors.

The quality of the mounted products must be such that their surface does not require additional finishing works, except for sealing seams, puttying and painting.

The surface of the products should be free of cracks, chips, grease and rust stains, mortar deposits, and exposed reinforcement.

2. Painting work should begin after the installation of the building is completed, starting from the top floor.

3. Surfaces to be painted are first cleaned of dust. The moisture content of plaster before painting should not exceed 8%, and of wooden surfaces - 12%.

4. Before painting, rough surfaces are puttied and smoothed, and small cracks are expanded and sealed with mortar to a depth of 2-3 mm . Grinding of putty and greased areas and smoothing of surfaces is carried out using a pneumatic trowel.

5. Paints, pastes and putties are prepared in a paint shop and delivered to the construction site in finished form.

To supply compressed air to mechanized tools, pneumatic struts made of solid-drawn steel are installed in stairwells. gas pipes with taps for air intake on each floor. Pneumatic risers are connected to a compressor installed on the first floor of the staircase.

In turn, paint injection tanks are connected to the pneumatic riser with rubber hoses, which supply paint compositions to spray guns, pneumatic rollers and fishing rods.

6. Ceilings are primed and painted using an electric spray gun with a universal rod, and oil painting of walls and floors is done using rollers with pneumatic supply of paint compositions.

Smooth foam rollers are used for painting doors, and profiled foam rollers are used for window frames.

Pipes are painted with special brushes, and metal fencing stairwells and balconies - with paired foam rollers.

The second time, the floors are painted with oil paint heated to a temperature of 25-30 °C.

7. In winter, the air temperature inside the building must be at least +8 °C (when measured at a height of 0.5 m from the floor).

8. Workers performing painting work must comply with the requirements of SNiP III - B .13-62 “Finishing coatings for building structures. Rules for production and acceptance of work" and safety regulations SNiP III-A .11-62 “Safety in construction.”

III. GUIDELINES ON LABOR ORGANIZATION

a) Plastering works

To perform plastering work, the building is divided into two sections, each of which includes two sections. The duration of plastering work on one section of each floor is 3 days. Plastering work is performed by a team of plasterers of 6 people (4 grades - 3; 3 grades - 2; 2 grades - 1)

Plasterers 4 grades. cut rustications between the floor slabs, arrange external window sills. One of them is a foreman, manages the work of the team and monitors the quality of the work performed.

Plasterers 3 grades they line the walls and ceilings in the vestibule with sheets of dry plaster, plaster the brick walls in the staircases, fill the gaps between the walls and baseboards and between the door frames and platbands with mortar, and also together with a 2-size plasterer. seal the passage of heating and water supply pipes with mortar and notch the edges of the slabs on the ceilings with caulking of the seams.

b) Painting work

All painting work is performed by a team of painters of 18 people, consisting of 3 units. The first link (5 grades - 1; 4 grades - 2; 3 grades - 1; 2 grades - 2) prepares surfaces for adhesive painting, and after preparation is completed, performs adhesive and oil painting.

Painter 5 sizes is a foreman. He manages the work of the team, monitors the quality of the work performed and, together with the 4th grade painters. performs priming of surfaces for adhesive painting and fluting of surfaces after the first and second painting with oil paint.

Painters 4 sizes perform surface priming for adhesive painting and improved adhesive and oil painting.

Painters 3 and 2 grades. clean the surfaces from dust, smooth the rough surface of the plaster and, after priming, sand the surface with sandpaper.

The second link (4 grades - 1; 3 grades - 2; 2 grades - 3) prepares surfaces for oil painting.

Painter 4 sizes Performs priming and fluting of surfaces and supervises the work of the unit.

Painters 3 sizes They perform continuous putty, sanding with pumice after putty and sanding with sandpaper after priming the surfaces.

Painters 2 grades smooth out the roughness of the plaster surface with the end of a tree or a flange, fill out cracks, lubricate and sand the greased areas.

The first link of the brigade performs work in sections 1 and 3; the second link in sections 1 and 3, and then moves to sections 2 and 4 and performs work in the sequence indicated on

The third link of the brigade, consisting of 6 people (5 units - 1; 4 units - 2; 3 units - 1; 2 units - 2) performs the same work as the first link, but in sections 2 and 4.

2.7. Clean the surfaces and cracks on it from dust, dirt, splashes and drips of solution using metal scrapers, a flake, artificial pumice fixed in a clip or a hinged grater (Fig. 1, 2). Grease stains are washed with a 2% solution of hydrochloric acid using a brush; efflorescence on the surface is swept away with brushes, the cleaned areas are washed and the surface is dried to a moisture content of no more than 8%. The cracks are opened with a plaster knife or a metal spatula to a depth of 2 mm.

Surface priming

2.8. For painting water-based compositions The first priming of the surface is carried out with a soap maker prepared in accordance with TU 400-2-143-77 (notice No. 1 on the extension until 1982) from bone glue, drying oil, laundry soap and water.

Soap primer at a construction site is prepared from a concentrated base (jelly) produced by the Stroydetal plant of the Mosotdelprom trust in the form of briquettes weighing 1 kg. The jelly is used for 10 days in summer and 20 days in winter. To prepare the primer, the weight portion of the jelly is poured in two parts hot water (t= 80 °C). Then the composition is stirred until the jelly is completely dissolved, add 3 parts cold water and mix thoroughly again. Before use, filter the primer through a sieve with 625 holes/cm2. The primer must be uniform, without traces of delamination, undissolved pieces of soap, and also without grains of sand and other debris. Apply primer mechanized way using an electric spray gun or spray gun. To obtain a uniform layer of primer, the fishing rod is moved along the surface at a distance of 0.75 m from the seam, simultaneously making smooth circular movements in a spiral. The second and third priming is carried out with a painting composition diluted with water to a viscosity of 40 - 43 seconds according to VZ-4, applied using a roller.

2.9. Before painting with oil compositions, surfaces are oiled with the following composition:

drying oil, kg - 1

pigment for tint, kg - 0.05 - 0.1

solvent (turpentine, gasoline, etc.), kg - 0.05 - 0.1

With thorough mixing, pigment is introduced into the drying oil and the mixture is passed through a sieve with a mesh of 918 holes/cm 2. Before use, add solvent to the composition until it reaches a working consistency.

The second and, if necessary, third priming is done with a color that matches the color of the final painting, diluted with drying oil or emulsion to a more liquid consistency.

The primer is applied to the surface in a thin, even, continuous layer, without gaps, carefully shaded. The primed surface should have an even color without isolated glossy or matte areas.

2.10. Embroidered cracks, cavities and other irregularities are filled with putty using a steel or wooden spatula. After the greased areas have dried, they are polished using pumice inserted into the holder or sanding paper attached to the holder.

2.11. The putty used for filling cracks, cavities and leveling surfaces must be a homogeneous, non-separating mass, have the property of strong adhesion to the surface, and can be easily leveled on the surface being treated. The putty is prepared centrally at the Stroydetal plant and supplied to building object packed in plastic bags weighing 15 kg. At the work site, the putty is passed through for grinding in a paint grinder SO-116 (if necessary).

The first continuous putty should be carried out with a composition that differs in color from the first primer layer and the partial putty layer.

The putty is applied in a uniform, continuous layer 2 - 3 mm thick “on a tear” with a metal or plastic spatula, followed by smoothing and removing excess putty until gaps in the lower layer appear from underneath it. The putty should only fill the depressions. The second and subsequent solid putties are made with a composition different in color from the first, etc. (Fig. 3, 4).

2.12. Solid putty is polished using mechanical grinders IE-2201A using sandpaper mounted on a wooden grater and pumice until a smooth surface is obtained, followed by dust removal with a vacuum cleaner.

2.13. Surfaces prepared for painting should not be bleached, and also should not have deviations exceeding those given in the table. 2, cracks in places of putty, visible stripes and stains (GOST 22844-72).

table 2

Requirements for surfaces prepared for painting

Type of finish	Permissible deviations
	surfaces from the plane	from the vertical or horizontal of the window and door slopes, pilaster, husk, usenkov	curved surfaces from the design position	rods from a straight line (for the entire length of the rod)
Improved coloring	no more than 2 irregularities with a depth or height of up to 2 mm	1 mm per 1 m of height or length, but not more than 4 mm for the entire element
High quality painting	no more than 2 irregularities with a depth or height of up to 1.5 mm	1 mm per 1 m of height or length, but not more than 2 mm for the entire element

Surfaces prepared for painting must be checked anywhere, but in at least three places for unevenness and local defects.

Painting the surfaces of building structures indoors with water-based paints

2.14. Emulsion paints are produced by industry different colors, ready to eat. Before use, mix the paint thoroughly and bring it to a working consistency by adding water. Water-based paints cannot be applied to surfaces previously treated with vitriol.

2.15. For the first coloring, viscosity water-based paint adjusted to 50 - 70 sec, according to VZ-4, and for the second - 70 - 80 sec. The surface is painted with rollers on elongated handles directly from the floor or with brushes. Before this, with a hand-brush, they make a layer of the ceilings and baseboards and paint the inner corners.

Painting the surfaces of building structures indoors with oil paints

2.16. Oil paints are a suspension of the corresponding pigment (iron lead, mummy, ocher, etc.) rubbed into drying oil.

Before use, they are brought to a paintable consistency by diluting with natural drying oil in an amount of 30 - 40% of the weight of the thickly grated paint. After diluting with drying oil, the paint is, if necessary, diluted with white spirit in an amount of no more than 5% of the weight of the diluted paint.

If the primer is applied manually, it is prepared according to the recipe specified in paragraph 2.9. Drying oil is added to thickly rubbed paint of the same color as the paint composition for subsequent painting.

When applying the primer by air spraying, a VM emulsion (water: oil) is used, prepared centrally at the Stroydetal plant of Mosotdelprom. The emulsion is delivered to the construction site ready for use in cans.

Apply the emulsion using an electric spray gun or spray gun, see paragraph 2.8.

2.17. Painting with water-based and oil-based paints is done with rollers or brushes. When painting with a brush, it is immersed in a container with paint to 1/4 of the length of the bristles. First, the paint is applied in bold, slightly receding stripes from one another and shaded in the transverse, and then, finally, in the longitudinal direction.

When painting with a roller, the roller is lowered into the bath and rolled once or twice along an inclined grid, squeezing out excess paint. Then roll the roller over the surface. Painting is done in two or three passes with a roller: the first pass is carried out with vertical movements of the roller; the second - in the horizontal direction, shading the applied layer. With each subsequent pass of the roller, the previous one should be overlapped by 3 - 4 cm (Fig. 5).

2.18. Fluting is performed with the end of a dry brush without pressing on the flute using reciprocal movements of the flute until complete removal from the surface of brush marks and streaks (Fig. 6).

2.19. Trimming (if necessary) is performed with a dry trimming brush, applying light blows to the freshly painted surface (Fig. 7).

2.20. Painting must be carried out in compliance with SNiP III-4-80 “Safety in Construction” and “Fire Safety Rules for Construction and Installation Work”.

Particular attention should be paid to the following: painting work at height should be carried out from inventory scaffolding, stepladders, universal trestle tables, mobile towers and other inventory devices. When performing work on flights of stairs it is necessary to use special scaffolding (tables) with different lengths support posts, installed on the steps.

The working floor must be horizontal and have guards.

Storage of painting materials is permitted only in places specially designated by the PPR.

When cooking painting compounds The following precautions must be taken when using a paint grinder:

do not allow the electric motor to overheat while the paint grinder is operating;

do not leave the working paint grinder unattended;

Do not allow unauthorized persons who have not undergone special training to operate the paint grinder.

Persons at least 18 years of age who have undergone special training and received a certificate for the right to work with these tools are allowed to work with electrified tools.

When cleaning the surface and sanding, you must use safety glasses. When washing surfaces with hydrochloric acid solution, workers must wear safety glasses. rubber boots and gloves. Dilute the acid by slowly pouring it into water. Paints, drying oils, and solvents should be prepared and stored in separate buildings equipped with ventilation. Containers for adhesives and paints must be stored in a specially designated place outside the premises on a designated area, at least 30 m away from the place of work.

2.21. The painting work front is divided into sections. The size of the units is determined taking into account the output achieved by the unit; each area must consist of a whole number of apartments in residential buildings, a whole number of premises in administrative, school and cultural buildings. In industrial buildings, the enclosure must consist of a whole number of spans.

2.22. Painting work with oil and water-based compositions is carried out by specialized units of two people each: painters of the 4th and 2nd categories. First, both members of the team prepare the surfaces for painting, that is, they smooth or clean the surfaces and fill out cracks. Then the 4th category painter primes the surfaces with an electric spray gun or roller. After drying the primed surface, the 2nd category painter performs partial lubrication individual places, then both members of the link perform continuous puttying of the surface, then grinding it. The second priming, puttying and subsequent painting of surfaces is carried out by both members of the team.

By changing the position of the head, you can obtain a horizontal or vertical direction of the torch.

5. Detailed information about the device and details of installation components are given in " Technical description and operating instructions for the installation for manual electropainting UREG-1."

III. TECHNOLOGY OF WORK PRODUCTION

1. The technology for painting metal structures using a manual electro-painting installation UREG-1 consists of performing organizational and preparatory operations, as well as operations for applying paint and varnish.

2. Organizational operations are carried out before the start of painting work. To do this you need:

• instruct workers on the rules of work;
• check the availability of solvents and paints and varnishes for the entire scope of work. All materials must be from the same batch;
• arrange all the tools and equipment necessary for work and repair possible malfunctions within the range of workers;
• ensure delivery of materials To workplaces using hand trucks.

3. It is prohibited to allow persons who have not undergone appropriate training and instructions to work on the UREG-1 installation.

4. Before starting work, it is also necessary to prepare the surfaces of metal products for the UREG-1 electropainting installation, prepare primer and paint compositions.

5. Preparing the surface of a metal structure involves removing rust and pockets of corrosion to ensure proper adhesion of the paint layer to the base.

6. Work on preparing the surface of metal products for painting is carried out in the following technological order:

• cleaning the surface from dust and dirt;
• cleaning the surface from rust;
• degreasing surfaces;
• grounding of products.

7. Before painting, the surfaces of metal structures must be cleaned of dust, dirt, splashes of solution and other contaminants using scrapers and rags.

8. The surfaces of metal structures must be cleaned of rust using steel brushes or chemically 3-4 hours before painting and degreased.

9. Chemical cleaning of rust and simultaneous degreasing are carried out with washing composition N 1120, which includes (in %): phosphoric acid - 30-35; hydroquinone - 1; butyl alcohol - 5; ethyl (denatured) alcohol. 20; water - 39-44.

10. Work on chemical cleaning metal surfaces with a washing composition consist of applying it with a rag, brush or roller to the surface to be treated, and after 30 minutes of exposure - cleaning the surface with metal brushes and rinsing with composition N 107.

11. If there are cavities and solid rust on the surface of metal structures, it is cleaned chemically using a composition of three parts hydrochloric acid and one part sulfuric acid, followed by neutralization of the surface with an alkali solution (NaOH) and rinsing with water.

In these cases, degreasing of the surface is carried out according to the technology adopted at enterprises Production Association Mospromelectroconstructions.

12. Metal products to be electropainted must be grounded with a device with a resistance of at least 100 Ohms.

13. It is prohibited to apply paints and varnishes to the surfaces of uncleaned and ungrounded metal products and structures.

14. Preparation of paints and varnishes for use in electropainting consists of bringing the primer and paint compositions to the required viscosity, checking their electrostatic properties (volume specific resistance, dielectric constant, etc.).

15. When preparing paints and varnishes, as well as inspecting the painted surface, you should use:

• compressor SO-7A;
• kilovoltmeter type S-100;
• microammeter type M-194;
• combined device type Ts-437;
• megohmmeter type MOM-4;
• thickness gauge type ITP-1;
• device PUS-1;
• quality factor meter E-4-4;
• viscometer VZ-4;
• stopwatch;
• thermometer;
• psychrometer;
• buckets, sieve, containers for paints and varnishes, rags, etc.

16. Materials used for electrostatic spraying must meet the requirements of relevant standards, technical specifications, as well as SNiP instructions.

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

It is most rational to use paints and varnishes that have 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 is no more than 30 s.

Volume resistivity is checked with a PUS device, dielectric constant with an E-4-4 quality factor meter, and viscosity with a VZ-4 viscometer.

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

19. When preparing the paint composition, you must be guided by the data in table. 1.

22. Preparation of paint and varnish materials, including dilution and control, must be carried out centrally for all operating painting installations (posts). In this case, it is necessary to be guided by the methodology attached to operational documentation installations UREG-1.

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

24. The manual electrostatic installation UREG-1 is prepared before starting work in order to ensure uninterrupted operation.

25. To prepare an electrostatic installation for operation, you must:

• check the integrity and cleanliness of mechanical equipment;
• ground the UREG-1 installation;
• connect the unit’s power cord to an AC network with a voltage of 220 V;
• attach the compressed air supply hoses to the paint sprayer and secure them with a clamp;
• connect material hoses to the paint injection tank and paint sprayer;
• set air pressure regulators and paint within the required limits;
• fill the paint injection tank with paint composition;
• Check for electrostatic charge by test painting.

26. Detailed information on preparing mechanization equipment for operation and maintenance of the installation is contained in the “Technical description and operating instructions for the installation for manual electropainting UREG-1” and the section “Labor methods and techniques” of this technological map.

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

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

29. When painting metal structures, one or more manual electrostatic installations UREG-1 can be used, depending on the painting location (centralized painting workshop or post-installation painting).

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

31. High quality coatings can be guaranteed if the technological regimes for applying paints and varnishes are observed (Table 4).

Table 4

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

Under the influence of dynamic air pressure, a high voltage circuit (10-14 kV) is closed using a pneumatic relay, in which the discharge electrodes are located. Sprayed and electrically charged, the paint composition increases this charge in the flow of ionized air and settles on the grounded product being painted.

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

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

35. After finishing the painting work, the paint injection tank, paint sprayer and the entire paint supply system must be washed. The paint supply system is flushed after the end of each work shift.

36. It is prohibited to leave the UTEG-1 installation in an unwashed state and with the paint heating tank filled with paint.

IV. METHODS AND TECHNIQUES OF LABOR

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

• painter (operator) 3 categories (M1) 1
• painter (operator) 4 categories (M2) 1

The mechanization equipment is serviced by a 4th category electrician working in the workshop.

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

3. A diagram of the organization of the workplace in the centralized painting shops at a stationary station is shown in Fig. 1.

4. A diagram of the organization of the workplace when painting metal structures on the production line of centralized workshops is shown in Fig. 2.

5. Scheme of workplace organization when painting metal structures on open areas is given in Fig. 3.

6. Carrying out work to organize the workplace with a real map and cost calculation is not provided for, but is decided additionally in each specific case.

7. The technological process of painting using a manual installation UREG-1 provides for the implementation of a set 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. Calculation of labor costs and schedule of the labor process were compiled for painting 100 sq.m of metal structures of average complexity and are given in tables 5 and 6.

9. Time standards 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. A set of operations: to prepare metal structures for painting, consisting of cleaning the structures from dust, rust, scale, solution splashes, etc., is performed by painters M1 and M2. Clean surfaces from dust and dirt with a rag; from rust - with a wire brush or chemicals, applying them to the surface with a rag, brush or roller and then removing them. After removing the rust, wipe the surface completely with a rag.

11. The preparation of working paint compositions is carried out by painters M1 and M2 in quantities not exceeding the shift requirement. In this case, the primer and paint compositions are diluted to the required viscosity, which is controlled with a VZ-4 viscometer, then the volumetric resistivity is determined with the PUS-1 device and the dielectric constant with a quality factor meter of type E-4-4; if necessary, they are corrected by introducing them into the composition required quantity emulsifier OP-7. The finished composition is filtered into the paint injection tank through a semi-pack mesh 05.

12. The preparation of the UREG-1 electropainting installation is carried out by painters M1 and M2. In this case, an external inspection ensures that there is no damage to the installation elements; All the handles on the panel are set to the “Off” position, if necessary, remove the conservation grease from the installation surfaces with a rag soaked in a solvent. Remove the plugs from the fittings 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 installation to the compressed air network and the electrical network, ground the installation and products.

13. Check the operation of the mixer by turning the knob on the top cover of the mixer air motor two turns, and then placing the tap labeled “Stirrer” in the “Open” position.

The frequency of switching on, duration and intensity of operation of the mixer 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 sprayer, it is recommended to turn on the stirrer during breaks in sprayer operation.

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

15. Open the valve labeled “Air pressure” and set the required spray pressure within 0.45 - 0.6 MPa. Install the movable nut on the nozzle head in a 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 optimal mode 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 “Network” position - the green light comes on and the sprayer is turned on. At the same time, the red light should light up, then, turning the knob " High voltage"on the control panel, set the current to 75 + 100 µA using a microammeter.

17. Set the required paint pressure, but not more than 0.4 MPa, using a tap marked “Paint pressure” and a regulator.

18. Verify the presence of coverage effect by testing a grounded metal cylinder with a diameter of up to 100 mm without turning it. The best coverage effect is achieved by turning the movable nut on the spray head in the area indicated by the marks.

19. When drawing up a work schedule and calculating labor costs, the operation of preparing electrical painting equipment was taken into account twice a shift (at the beginning of the shift and after the lunch break).

When preparing equipment one-time, it is necessary to make adjustments to the table. 5 and 6.

20. Technological operations applying priming and painting layers on the surfaces of metal structures using the UREG-1 installation is carried out by painter M2; first, he checks the position of the “Paint Supply” and “Paint Pressure” taps on the installation (they must be open), then takes the sprayer into right hand, holding it with the left, and pressing the trigger creates a torch of paint, directing it at the product being painted.

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

22. At the end of each shift or at the end of painting work, the M2 painter pours paint from the paint injection tank and pours 3/4 liter of solvent into it, connects the hoses and closes the tank with a lid. Sets the “Paint Supply” and “Paint Pressure” taps to the “Open” position, opens the sprayer and, pouring the solvent into an arbitrary container, rinses the paint supply system until traces of paint disappear. Then wipe the surface of the sprayer with a rag soaked in solvent.

23. When painting metal structures located above 3.5 m from the floor or ceiling, work must be carried out from mobile scaffolds.

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