1 range
This process standard applies to general construction steel doors and windows and metal surface application of ordinary, intermediate color paint paint project.
2 construction preparation
2.1 Material requirements:
2.1.1 Coatings: varnish, light oil, lead oil, blending paint (magnetic blending paint, oil blending paint), varnish, alkyd varnish, alkyd enamel, antirust paint Rust paint) and so on.
2.1.2 Filling materials: gypsum, white, floor yellow, red soil child, black smoke, cellulose and so on.
2.1.3 Diluent: gasoline, kerosene, alkyd material, pine water, alcohol and so on.
2.1.4 Drier: cobalt driers and other liquid materials.
2.2 The main equipment:
2.2.1 oil brush, knife, horn plate, oil brush, Tao Zi (dig brush door and window sash upper and lower mouth is not easy brushing parts of the tool), hole silk baskets, sandpaper, gauze, putty, steel skin scraper, Small oil barrels, oil spoon, half vats, buckets, wire pliers, small hammer, wire brush, high stool and scaffolding, seat belts and so on.
2.3 Operating conditions:
2.3.1 Construction environment should be well ventilated, wet work has been completed and have a certain intensity. The environment is relatively dry.
2.3.2 large area before construction should be done before the model, the relevant quality inspection and identification of qualified departments, the organization can organize large-scale construction team.
2.3.3 Before the construction of steel doors and windows and metal surface shape should be checked, there are deformed substandard, should be replaced.
2.3.4 before the operation should be a serious handover inspection work, and properly handle the remaining issues.
2.3.5 Brush finish paint must be installed before the glass.
3 operating process
3.1 Process flow:
Grass-roots processing → scraping putty → brush the first pass paint (brush lead oil → rub putty → frosted paper → loaded glass) →
Brush the second time paint (brush lead oil → Cabo, grinding paper → brush the last time blending paint
These are steel doors and windows and metal surface paint color mixing paint application of intermediate practices process. If it is common color paint paint project, its approach and process is basically the same, the difference, in addition to less brush again paint, only to find fill putty, dissatisfaction with the putty. If it is advanced mixed color paint coating engineering, its practice and technology are basically the same, the difference, the need to increase the second time full of putty putty, polished and brush the third times after coating, increase water sandpaper polished, wet cloth, brush Fourth times the paint, you can into a senior color paint paint works.
3.2 primary treatment: cleaning, derusting, scrub group. First of all steel doors and windows and metal surface of the floating soil, mortar and other clean. Brush the rust-proof paint but rusty steel doors and windows or metal surface, with a shovel to eradicate the bottom anti-rust paint, and then wire brush and emery cloth thoroughly polished, brush an anti-rust paint, anti-rust paint to be thoroughly , Metal doors and windows or metal surface of the trachoma, pits, missing edge, patchwork, etc., with plaster putty scraping smooth (metal surface putty weight ratio of gypsum powder 20, cooked tung oil 5, oil putty or alkyd putty 10, primer 7, the amount of water. Putty to be transferred into a soft, not hard, no honeycomb, pick the wire does not fall is appropriate). To be putty dry, with 1 sandpaper grinding, grinding sandpaper after the surface with a tidal cloth to wipe the powder clean.
3.3 scraping putty: with a scalpel or rubber scraper in the steel doors and windows or metal surface of the plaster over a full plaster putty (with the above Ibid), the requirements of scraping thin, close clean, uniform formation without flying thorns. And putty dry, polished with a sandpaper, pay attention to the protection of edges and corners, requirements to achieve smooth surface, straight line, neat line.
3.4 brush the first pass paint:
3.4.1 brush lead oil (or alkyd dull paint): lead oil with color lead oil, varnish, edible oil and gasoline from the preparation, with the same ratio before, after mixing over a basket, the winter should be appropriate amount of urge Dry agent. Oil consistency to achieve the bottom cover, do not flow, no significant brush marks is appropriate, the color of lead oil to comply with the color of the model. Brush the lead when the oil from the top of the box on the left side of the beginning of brushing, frame brush oil not to brush the wall, pay attention to internal and external color separation, thickness should be uniform, brush pattern must be smooth, brush the upper part of the brush and then brush Liangzi, all Liangzi brushing, and then brush the lower half of the box. Brush sash, such as two windows, you should first brush the left fan after brushing the right fan; three windows, and finally the middle of a brush. After all the sash outside the brush, hook with a very hook inside again.
Brush the door when the first brush son, and then brush the door frame and the back door, after brushing the door with a wooden wedge to the mouth fixed, all brushing, you should immediately check whether the omission, color separation is correct, and hardware contamination The paint is wiped clean. To focus on checking the line angle and yin and yang at the corner of whether the flow falls, leakage brush, wrapped edge, through the end of other problems, should be timely to achieve uniform color.
3.4.2 wipe putty: to be dry paint, the bottom of the putty contraction or defective place, and then plaster putty put up again, with the requirements and practices.
3.4.3 frosted paper: to be putty dry, with 1 sandpaper grinding, with the former requirements. After grinding with a tidal cloth to wipe the powder under the wipe.
3.4.4 Fitting the glass: See the glass installation process standard.
3.5 Brush the second time Paint:
3.5.1 brush lead oil: the same as before.
3.5.2 Cabo, scrub paper: Use a tidal cloth to wipe the inside and outside the glass clean. Be careful not to damage the surface and putty. Frosted paper Application 1 sandpaper or old sandpaper light mill again, with the former method, but be careful not to wear the primer, to protect the edges and corners. Grinding sandpaper should be cleaned, with tidal cloth to wipe the powder under the clean.
3.6 brush the last time blending paint: brush oil method with the former. However, due to blending paint viscosity, when brushing to brush more management, brush oil to full, not flow does not fall, bright uniform, consistent color. Brush the oil, the oil should be uniform, do not damage the smooth surface of the putty, the character see the line. Brush paint, it is necessary to immediately check it again, if found to have problems, should be promptly trimmed. Finally, with a hook or wooden wedge to open the door and window fan fixed.
3.7 winter construction: winter construction indoor paint coating project, should be carried out under the conditions of heating, room temperature to maintain a balance, the general construction of the paint ambient temperature should not be less than +10 ℃, relative humidity of 60%, not a sudden change. At the same time should be responsible for setting temperature and temperature of the doors and windows, in order to facilitate ventilation to exclude moisture.

3. Brush Tuomo Tu, do not check the light.
5.4 paint coating project is completed, should be assigned to care and management, prohibited touch.
6 should pay attention to quality problems
6.1 leakage brush, rust: rust generally occur in the steel doors and windows and metal surfaces and other projects, the main reason: First, the products in the factory because of the rust did not seriously rust painted on the brush; the second is due to transport and storage is not The third is the steel doors and windows or metal surface before installation, did not seriously check, did not do rust paint and paint brush anti-rust paint work, which is the main quality problems we should pay attention to.
Leakage brush occurs in the steel doors and windows, the next rise and rely on hinge facets and doors and windows frames, pressure seam on the bottom. The main reason is that the door is not installed with the oil well with the door, it often occurs under the brush does not brush the door to install the brush, and after the oil workers simply can not brush (unless the door hinge unloading heavy brush); And steel screens, not the pre-colored lead oil on the brush on the stretch yarn, coupled with strict liaison, etc., often less brush the phenomenon of paint again. Other leakage brush problem is mainly caused by the operator is not serious.
6.2 lack of putty, the lack of sandpaper: generally occur in the hinge slot, up and down to take the head, tenon joints and nail holes, cracks, knots and edges and other defects. The main reason is that the operator is not seriously in accordance with the rules to operate due to process.
6.3 Flow falling, wrapped Leng: The main reasons are: l: First, because the paint is too thin, the film is too thick or the ambient temperature is high, dry paint and other reasons, are easy to cause flow fall. Is due to the operation sequence and improper practices, especially in the door and window edge nuclear separation, such as once the oil and the operation of large attention, it is often likely to cause the flow fall, wrapped Leng.
6.4 brush pattern Obviously: the main oil brush small or pumping brush is not soaked, brush hard hair caused. Apply the appropriate brush, and the oil brush with a thin foam soft after use.
6.5 wrinkles: mainly bad paint quality, with the uneven distribution, solvent evaporation fast or high temperatures, add driers and other causes.
6.6 Hardware pollution: In addition to the operation should be fine and timely cleaning of the hardware and other pollution at the clean, should try to door locks, handles and latches and other after-loading (but the position and the hole in the hole before drilling) to ensure clean and beautiful hardware.
6.7 Reflecting: As the steel doors and windows and metal roof oil absorption uneven speed or uneven surface, coupled with the indoor moisture or primer is not dry and excessive diluent and other reasons, may produce local glossy gloss luster shine.
