油漆工序介绍（Introduction of paint process）

油漆工序介绍（Introduction of paint process） 油漆工序介绍(Introduction of paint process) The painting process includes wooden painting and wall painting, both of which are done by rubbing: The wood paint process is: 1, the base surface treatment: the decorative panels and lines of dirty marks, or carpentry pencil marks clean out 2, line grinding: the woodworking side of the line did not deal with good grinding treatment, and can not wait for the paint after grinding; 3, brush the first primer; 4. After 24 hours, polish with sandpaper No. 240 and clean with a clean towel; 5, filling putty, the hole part flat with Putty Repair nail line nail hole and decorative panel; 6, second primer; 7, 24 hours later, use 240 sandpaper polish, and then wipe the surface with a clean towel; 8, check again nail hole repair, not the local timely fill; check the interface made of wood with the other interface use paper separately, important place to use newspaper to protect, preparing for the spray paint work; 9, when the front of everything is ready, you can spray the top coat for the first time; 10 or 24 hours later, use 400 sandpaper to gently polish the surface; 11 and second spray finishes; 12, 24 hours after looking at the top coat, such as the surface layer is very good, the paint film is also full, it means that wood paint can be completed; In case of a small drop, you can use 600 sandpaper to soak the water and then fine coat the top coat, and so on, you can use a wax to protect the finish coat. Wall painting 1, water wall (the original wall wetting, shovel when saving) 2. Remove the part of the original wall that has been soaked 3, after the wall dry, scraping putty (depending on the original wall condition to do two to three times, every time should be completely dry and then do it next time), 4. Sanding and smoothing, 5, brush primer and finish (or roll brush), primer two times, top coat three times, each time after thoroughly dry, and then do the next. 6, cracks on the wall, but also to do anti crack treatment. In the putty before, in the cracks with at least 108 adhesive beyond 20 cm wide cracks on both sides of the dacron cloth, dry after guanizi. Brush wood paint (1) paint oil or toning oil (Note: limited to the project with color change, general engineering does not need this process). (2) brushing varnish to protect primer (if there is no 1 process), this is the first step. If the primary color is to be removed, then the surface must be cleaned and the first protective primer shall be cleaned immediately after the material is purchased. Primers are usually made with topcoat. Note: the surface layer of varnish must operate in the paint before. (3) dust and dirt on wooden surfaces are cleaned. (4) surface with sandpaper or wood line surface polishing. (5) brush the first paint. (6) after drying, the toner is mixed with synthetic powder, powder and fly powder to make putty, such as nails, eyes and tree scars, so as to be the same as color matching. (7) after drying, polish the rough parts of the toner with fine sandpaper, which is crucial. (8) brush the paint. (9) polish with fine sandpaper after dry. (10) brush the paint. The paint with fine sandpaper polished again and so on. If there is a special primer, change the first coat to a special primer. (11) with a damp cloth to wipe the surface of wet wood, then polished with sand paper wet surface, commonly known as water. (12) brush the last paint. Generally speaking, count the last paint, you need to paint the top 4-8 times, there will be more quality effect. The more layers paint, the better, but generally not more than 10 times. During the construction of wet weather, the paint film will be whitish, and the nitro magnetized white water of diluted dosage of 10%-15% can be eliminated. Version 2 Matters needing attention 1. paint mainly latex paint and wood paint, the former is mainly inside and outside the wall, which refers to the floor, modeling, furniture, including cabinets and so on; The 2. panels, wood, paint 2 transparent primer of good health - brush - eye patch - brush third times - panel, transparent primer nailhole repair color (color furniture surface consistent). Ashtree, from rough pores veneer, opening varnish, should first brush primer after patch eye (open white paint should be in the paint brush brush 2~3 times before increasing global water), the final construction should be sprayed; 3. patch eye can use 325 black cement +801 glue, not too thick. The number of times, a number of Board approved a nail in the eye, no gap number of eyes, many joints is undesirable (seam; if the proposed expansion plaster) anti rust paint group, workers have to carefully, one by one group rather than a little poke careless. Not seriously, the paint does not stick nails, eyes, buttocks, that is to say, did not fill the nail or eye completely covered with paint. 4. package angle material can use metal or nonmetal material, nonmetal material is mainly plastic extrusion section, usually 25*3000, metal material, generally aluminium alloy or stainless steel, 30*3000; The 5. panel dust clean, decorated panels of wood on the glue, fingerprints, pencil clean; 6., the top beam uneven processing: more than 10MM, uneven suggests posting gypsum board, because the putty thick, easy to hang or hollowing, late fall in trouble; 7. paint to the bottom putty dry, can do second times; 8., cold weather, can not use things forced drying, uneven heating when the glue is not firm, the use of oil Ting, so that the whole room to raise the temperature is a good idea; 9. paint choice: first to determine what to do, the top wall paint (usually refers to the latex paint, latex paint and wallpaper putty) ratio is not the same, the last line of the putty is not the same, the surface roughness is not the same; 10., the use of anti cracking network: the original wall cracks, cracks, slotted a lot of time, it is strongly recommended to use grid cloth, if necessary, you can use mesh cloth + Kraft + mesh cloth enhanced processing; 11., fireworks, paint and other flammable items should be classified, stacked in a secure position, materials stacked neatly; 12., the construction site is not allowed to cook; 13. painter's own protection, including eye care, gas masks must be equipped with 14. protection of finished surfaces 15., the repair cabinet side door side, side line, skirting the gap. Sequence: 1. clean up after entering the field, first clean up the materials and garbage left behind by the previous type of work, and protect the floor tiles, marble and other finished products. 2. - shovel shovel wall sealing net original wall, top surface or old powder coating, shovel to the original mortar powder layer must, then with a broom to sweep the dirt, to be dry after rolling over mixed glue (seven leaf wood glue glue 10%+801 60%+ water 30%), ensure that the walls absorb enough glue to enhance the bond strength of new the putty and original foundation. 3., vertical angle - Li Yang Kok must use 801 glue plus pure plaster, in order to ensure the fastness of the yang angle, possible conditions should be adopted Yang Kok anti-collision bar, vertical angle should take full account of the wall roughness, with the wall fixed angle. The 4. patch patch in front of black eye -- check the screw "headless" 1-2mm, to ensure that the rust layer thickness, cement and building materials should be used black glue 801 modulation, gypsum board found loose shall notify the carpenter rectification. 5.: check the expansion joints of gypsum board joints is in line with the standard (5-8mm), which does not meet the standard notice of woodworking rectification, gypsum board cutting edge should be sealed again mixed with glue (3 copies seven copies of 801 +7 leaf wood glue glue) with reinforced gypsum board paper edge fastness, brush glue should be the first to use the paintbrush Shan net slot dust. Expansion joints must use pure gypsum powder, not old glue 801 glue powder, add a small amount of seven leaf wood glue, gypsum to batch flat light. 6. - Mount joint joint band before using 100 mesh wheel grinding sand paper, kraft paper, the best use of double-sided adhesive with construction, 1 copies of 1 copies with water available white paper, the original glue on the wall. Kraft paper shall not be soaked in water, so as not to affect the quality of joints. Easy to crack parts (especially the large area partition with the original wall or column junction) must add a layer of 10cm wide kraft paper, kraft paper pasted on the surface after brush a layer of glue or a layer of gypsum closed group expansion. Seven Pull ash - cellulose shall be 12 hours ahead of cook, with glue, 801 glue not tim. The last time the proportion of cellulose and glue from the first to must agree, in case when a shell or powder grinding bald phenomenon, in principle, to minimize the use of cellulose, gypsum powder and old powder ratio should be 1:4, to shorten the drying time. Check the straightness of the ruler to ensure the large area of the dust. The 8. batch of ash - the first batch of ash, it is recommended to use large gray board to ensure a small area of flatness, second times can use small gray board. 9. - the first time grinding with 240 mesh rubber water grinding, then use 400 mesh fine sand sediment. 10. glue - 801 glue plus 1/4 water seal, the glue must be sealed. The 11. batch of latex paint putty - 400 mesh rubber grinding water wall, and then use the white latex paint from talcum powder and a small amount of cooked powder scraping, cooked powder less, to accept light compaction putty. 12. - grinding with 600 mesh fine rubber grinding, grinding as a circle arc construction, after grinding Shan as dust. 13. protect all doors and windows and finished products. 14. spray latex paint - spray paint must be in clear weather, in order to paint film forming quality. A good primer spray dried with 600 mesh fine rubber grinding. Then spray the top coat. When spraying, make sure the film thickness is guaranteed. 15. clean up - clean all the protection and clean up the paint in case the protection is not in place. Emulsion paint brushing construction classification Latex paint brush construction methods can be hand brush, roll coating, spraying and batch scraping, batch scraping with less, for paint craft requirements are quite high. Hand brush less material loss, quality is relatively guaranteed, is more used in family decoration methods. But the brush brush has a longer construction period, so it can be combined with roll coating. The specific method is: the large area is to use roll coating, and the corners and corners are manually brushed. This improves the brushing efficiency and ensures the quality of brushing. The construction of the paint must stir before use, to choose your own color, alkali resistance, light color paste mixed with liquid paint, paint color ban into dry powder. After finishing the latex paint, at least stirring for more than 5 minutes, so that the color of olive evenly before construction. Use latex paint brush brush, paibi should soak with water wet, cleaning off the brush after use. The first latex paint should be diluted with water after brushing, brushing is the first post, a brush, a brush to brush, after a row must be immediately before a paibi, shall not leak brush, brush brush dipped coating was not too much. Second times brushing, should be less than the first time to add water, in order to increase the consistency of paint, improve the cover power of paint film, the specific amount of water should be based on different brands of latex paint to determine the consistency. The film is dry, do not use hand cleaning wall brush, hair, etc. should be dry with fine sandpaper off?. Whether brushing several times, the last time should be up and down along the brush from the wall, one end to the other end walls, joint part to join each other, Jiecha brushing, brush brush to straighten out, not too big. Brushing should be continuous and rapid operation, brush once, the middle shall not be intermittent. Roll is used for finishing roller brush, its technical essentials: paint mixing, viscosity to fit into the flat tray after construction, part of the barrel in intraday dip will roll coating, the coating roller rolling cylinder evenly attached to the reel drum. Brushing the wall, the hair rolled by W on mobile, will generally paint onto the wall, and then hold down roller cylinder, close to the wall, up and down smoothly rolling back the coating uniform, the roller cylinder in one direction with a roll. Roll to the jointing part, should use the empty rolling rolling over sub nonstick coatings, lest the jointing part of uneven exposed obvious signs. Is the use of spray pressure or compressed air, through spray spray paint on the wall, the main operation technique is: first of all, should adjust the spray pressure of air compressor, generally within the range of 0.4~0.8 MPa, the concrete construction should be adjusted according to the specification of paint products used. When spraying, hold the spray gun firmly, The paint outlet shall be perpendicular to the painted finish. The spray gun shall be moved in parallel with the painted finish. The lance shall be at the proper speed of movement and shall be consistent. Generally, the motion shall be uniform between 400~600 mm per minute. When spraying nozzle distance is coated surface should be controlled at a distance between 400~600 mm, the gun should be straight parallel or perpendicular to the ground motion, the moving range is not too large, the general line spraying 700~800 mm after turning 180. Reverse spraying the next line, two lines overlap width should be controlled at the spraying width of about l/3. In general, compared with roll coating, spraying and coating are better and more beautiful. The disadvantage is that the materials are more expensive, and the later stage repair (usually coated with hand paint) is more troublesome, inconsistent with the original spraying surface The commonly used latex paint brands: Dulux, Nippon, master, Fang, Fenlin, desert oasis, Maydos Wood: big treasure, Huarun, red apple, Carpoly, three trees, ivy, evergreen, Bauhinia, giraffe Version 3 Construction process of varnish: Clean the wood surface, sandpapering, WidePlus Bo, sanding, scraping powder with 1 putty, sandpaper, full second times scraping putty, fine sandpaper polishing, brushing, brush the oil varnish to fight for color, after filling putty, fine sandpaper, brush second varnish, fine sandpaper, brush third varnish, water sandpaper to polish back light, waxing, polishing. Mixed color paint construction process: First clean the dust on the surface of the base, repair, matte paper to draw basic knots at play, putty, primer paint, Tu oil first full Guanizi, polished, brushing coating, coating, dry brushing surface layer, after filling Putty Repair, polished clean third times finish paint brushing second times to finish third times, finishing coat, polishing wax. We will focus on the operation of wood paint. The process of wood paint is mainly divided into two kinds: one is varnish process, and the other is mixed oil process. Varnish process steps is as follows: first coloring oil or oil color (Note: only with the color requirements of the project) the next brush varnish veneer, wood protection. If the primary color is to be removed, the surface must be cleaned after the material has been purchased, and the first time the sealing of paint shall be protected". Primers are usually made with topcoat. It should be noted that the varnish must be treated before the wall paint is painted. The next thing to do is to clean up the dust and dirt on the woodwork. Then the panel or wood line surface polishing with sandpaper, brush the paint. Wait until the paint is dry toner used after deployment and powder mixing, such as glue putty nailhole and cover up scars down the tree, with the same character. Be sure to polish the rough parts of the toner with fine sandpaper after the paint is dry. This is the key point, and you must pay attention to the effect of sanding. The paint brush second times, and then dried with fine sandpaper, then brush the paint again (i.e. paint with fine sandpaper polished again and so on. If there is a special primer, the paint as special primer) to this end again, use a damp cloth to wipe the surface of wet wood, then polished with sand paper wet surface, commonly known as water. When the water process is finished, you can brush the final paint. In general, the final paint requires a total finish of about 4 to 8 times for better quality. The more layers paint, the better, but generally not more than 10 times. Also pay attention to is that in wet weather construction, the paint film will be whitish phenomenon, then properly add diluted dose of nitro 10~15% magnetized white water can be eliminated The mixed oil process steps is as follows: first clean the surface of wood dust and dirt, and then use the putty mix full batch of wood surface, the dry sandpaper polishing brush the paint, and points at the same side, to be dry after polishing with sandpaper, then brush paint second times, to be dry after repeated use sandpapering procedures, then brush paint third times. In general, blending oil between two and three times is advisable.
