Common knowledge of coating: causes of blistering and pinhole on coating surface and Solutions

Core tip: there are a lot of small bubbles on the surface of the coating, and then the bubbles break or break when the paint film is abraded to form dense pinholes The reason for bubble or pinhole phenomenon is that there are gases (solvent vapor, water vapor, expanded air or other gases that can be mixed into the paint, such as carbon dioxide, etc.) in the coating to break through the coating and form bubbles, and then break or wear to form pinholes When the dry speed of the surface layer is slightly higher than that of the interior layer, when the surface layer has started to condense and the interior solvent or air is still evaporating, the surface layer of the coating will break through and form bubbles 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: in the coating surface first appear a lot of little bubbles, and then bubble rupture or in the paint film when grinding to form a dense pinhole like small holes The reason for bubble or pinhole phenomenon is that there are gases (solvent vapor, water vapor, expanded air or other gases that can be mixed into the paint, such as carbon dioxide, etc.) in the coating to break through the coating and form bubbles, and then break or wear to form pinholes When the dry speed of the surface layer is slightly higher than that of the interior layer, when the surface layer has started to condense and the interior solvent or air is still evaporating, the surface layer of the coating will break through and form bubbles 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,
