Paint knowledge | main defects of latex paint coating: rust spot

Core tips: causes: · rust of iron without anti rust treatment · weathering of cement, corrosion of steel due to water air penetration · rust prevention methods of galvanized iron nails after grinding or excessive contact with air: · determine whether there is rust source in the wall during construction · treatment methods of anti rust primer for materials easy to rust:· Clean the rust, polish the nail head, operate the iron nail countersink according to the new wall surface, apply the antirust primer point and then recoat; · when the internal reinforcement is rusty, knock off the external cement mortar and remove the rust from the reinforcement 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 Home of coatings: causes: · rust of iron without antirust treatment · weathering of cement, corrosion of steel due to water air penetration · rust prevention methods of galvanized iron nails after grinding or excessive contact with air: · determine whether there is rust source in the wall during construction · apply anti rust primer to materials easy to rust Treatment method: · clean the rust, polish the nail head, operate the nail countersink according to the new wall surface, apply the antirust primer and then recoat it; · when the internal reinforcement is rusty, knock out the external cement mortar, and focus on the news and coating of coating, diatom mud, paint coating, coating technology, fire-resistant coating, diatom mud, paint coating, coating technology, Decoration knowledge and effect drawing of fireproof coating,
