Core tips: 1 The content of oil painting oil painting is one of the basic methods of finishing doors and windows, dado, heating hood, supporting furniture, etc On the basis of changing the color of wood, oil painting can keep the original pattern of wood The decoration style is natural, simple and elegant Although the construction period is long, it is widely used 2 The procedure of oil cleaning is a highly technical construction project The standard construction procedure is: clean the surface of wood → polish with sandpaper → moisten the powder → polish with sandpaper → fully scrape the putty for the first time, and polish with sandpaper& Application scope and advantages of roller ceramic coating Recommended introduction: the surface of ceramic rubber plate used for roller ceramic coating is cast into durable rubber plate by hundreds of independent small ceramic pieces Each ceramic piece has raised characteristics Under general conveyor belt pressure, thousands of unique cast bumps can produce positive traction, prevent slipping and extend the service life of conveyor belt roller At the same time, the bottom layer adopts high-quality rubber, which has strong elasticity and can play a good impact resistance role The scope of application of roller ceramic coating is one three six 83857180 (the same as V) 1 Roller coating in extremely harsh working environment 2 The belt joint is not suitable for fixing with iron buckle; 3 It is suitable for leather Paint Home News: 1 Oil painting is one of the basic methods of finishing doors and windows, dado, heating hood, supporting furniture, etc On the basis of changing the color of wood, oil painting can keep the original pattern of wood The decoration style is natural, simple and elegant Although the construction period is long, it is widely used 2 The procedure of varnish painting is a highly technical construction project The standard construction procedure is: clean the wood surface → polish the sanding paper → moisten the powder → polish the sandpaper → fully scrape the putty for the first time , sandpaper polishing → fully scraping the second time of putty, fine sandpaper polishing → painting the oil color → painting the first time of varnish → matching the color, re filling the putty, fine sandpaper polishing → painting the second time of varnish, fine sandpaper polishing → painting the third time of varnish, polishing → after the effect is satisfactory, the sandpaper will be polished to remove the light, wax and polish The quality of the wood surface oil cleaning construction is very different, which can reflect the professional and technical level of the operators It is necessary to operate in strict accordance with the standard procedures to ensure the decoration effect and project quality after painting 3 The base treatment and grinding before oil cleaning and painting is an important process of painting varnish First, the dust, oil and other impurities on the surface of wood should be removed, and the nail holes and nail caps should be sunk into the wood for 1mm as required The nail caps should be smashed and then trapped When sanding the sandpaper, wrap the sandpaper around the short wood square and pad it for grinding The line angle and large surface shall be ground and polished, and the surface shall be cleaned with damp cloth or cotton wire The upper lubricating oil powder is also an important process of varnish painting The oil powder is mixed with white powder 2 gasoline 2 light oil = l222821 (mass ratio) and added with color material The consistency is appropriate in the form of thin paste During the construction, apply the oil powder on the surface of the wood with cotton thread dipped in the oil powder, rub it back and forth with hand, and rub the oil powder into the inspection eye of the wood It is required that the exposed parts on the surface of the surgical instrument F should be wiped, and there should be no leakage, or the face will be painted after the varnish is applied After the oil powder is slightly dry, wipe the oil powder with hessian cloth or wood shavings, and scrape the line corner with scraper, without any residual block oil powder After the oil powder is dry, use No.1 sandpaper to polish it gently along the wood grain First, grind the line angle, then the plane, until the surface is smooth, but the oil powder at the edges and corners cannot be completely worn off If the mortar stubble is exposed, add the oil powder, dry it and then regrind it, and wipe it with damp cloth or cotton wire The putty is made by adding appropriate amount of water with gypsum powder 2 gloss = 2027 (volume ratio) The amount of pigment added shall be based on the principle of slightly lighter color than other parts Use a knife or scraper to scrape the putty into the nail hole, joint, etc when scraping, it shall be horizontally and vertically plastered, scraped and cleaned After drying, it shall be lightly polished with sandpaper along the wood grain, and cleaned with damp cloth or cotton thread Home of coatings is specialized in coatings, diatom mud, paint coating, coating technology, fire retardant coating news and coating, diatom mud, paint coating, coating technology, fire retardant coating decoration knowledge and decoration renderings,
