Abstract: Dust in the air is the enemy of coating. Dust with particle size greater than 5μm mixed into the paint layer can make the surface of the paint film to produce concealer points visible to human eyes. Therefore, appropriate dust-proof measures must be taken to reduce the concentration of dust in the air supply,… Continue reading Selection and management of air conditioning filter in painting shop?
