Coating knowledge: particle source analysis of automobile painting line

Core tip: most of the domestic coating lines are applied with electrostatic spraying, and the paint utilization rate is basically controlled at 60% ~ 80% A large amount of paint mist is easy to be generated during the painting process, most of which will form paint slag, some of which will float in the air, some of which will be adsorbed on the automatic spraying equipment and the wall panel of the paint spraying room, or scattered on the clothes, hats, gloves and other surfaces of the painters, and finally gather to form Particles then pollute the vehicle body, especially the wet film, forming more difficult to handle particles, accounting for more than 40% of the total particle formation Effective measures: (1) set up circulating water under the spray booth, and use the circulating air to bring the paint mist to the water for treatment (2 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 coating Home news: most of the domestic coating lines are applied with electrostatic spraying, and the paint utilization rate is basically controlled at 60% ~ 80% A large amount of paint mist is easy to be generated during the painting process, most of which will form paint slag, some of which will float in the air, some of which will be adsorbed on the automatic spraying equipment and the painting wall panel, or scattered on the clothes, hats, gloves and other surfaces of the painters, and finally form particles Particles then pollute the car body, such particles will especially pollute the spray wet film, forming more difficult particles, accounting for more than 40% of the total particles Effective measures: (1) set up circulating water under the spray booth, and use the circulating air to bring the paint mist to the water for treatment (2) Lay anti-static plastic paper on the wall panel, apply Vaseline adhesive, and replace once a week (3) For the part of the automatic rotating cup and atomizer, the paint mist will form on the surface due to the accumulation of the paint mist under the electrostatic action for a long time Therefore, the paint mist will be cleaned twice per shift, and the special cleaning cloth will be used for cleaning Generally, there are many filaments on the cloth 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,
