Paint knowledge: main defects of wood paint coating: discoloration

Core tips: reasons: · bleaching agent of wood bleaching treatment is not cleaned, nitrocellulose primer paint is not dry, that is, polyurethane top coat is applied, sunlight is directed on the paint film of indoor paint, and the product contains substances that are prone to yellowing Prevention methods: · clean the chemical impurities on the surface of wood · use the sealing primer · use the same type of primer · do not put the furniture in the position where the sun can shine · use the paint treatment method of yellowing resistance: · remove the old paint film, and then treat it according to the method in prevention · use the paint with yellowing resistance to repaint Several ways of roller coating Recommended introduction: roller coating includes rubber roller coating, insert plate roller coating and ceramic rubber roller coating The following is a detailed introduction of these three ways of coating The function of roller rubber coating is to increase the friction derivative between the conveyor belt and the cylinder surface during transmission, so as to reduce the friction coefficient of the conveyor belt on the cylinder surface, reduce the mutual wear of the sliding machine of the conveyor belt on the cylinder surface, improve the traction force during operation, and extend the service life of the conveyor belt and the electric roller One, three, six, 8385-7180 (V) rubber rollers are covered with diamond rollers and flat rollers, generally pure rubber plates The rubber coating of the inserted plate roller is divided into tile shell type roller and Paint Home News: Reason: · bleaching agent of wood bleaching treatment is not cleaned, nitrocellulose primer paint is not dry, that is, polyurethane top coat is applied, sunlight is directed on the paint film of indoor paint, and the product contains substances prone to yellowing Prevention methods: · clean the chemical impurities on the surface of wood · use the sealing primer · use the same type of primer · do not put the furniture in the position where the sun can shine · use the paint treatment method of yellowing resistance: · remove the old paint film, and then treat it according to the method in prevention · use the paint with yellowing resistance to repaint 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,
