General knowledge of coatings: requirements of building coatings for additives

Core tip: auxiliary agent is an indispensable part of architectural coatings, although the dosage is not large, as long as it is used properly, it will give coatings some special properties The commonly used additives in architectural coatings are wetting agent, dispersant, film-forming agent, thickener, anti settling agent, defoamer, mildew inhibitor, etc As an auxiliary, it must meet the following requirements 1 It has good compatibility with the base material and can not produce flocculation or other chemical reactions It is not sensitive to the pH value of the system or other salts, and cannot affect the performance of the coating and coating Within the effective service life after construction of building coating, there will be no precipitate 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: auxiliary is an indispensable part of architectural coatings, although the amount is not large, but as long as it is used properly, it will give paint some special properties The commonly used additives in architectural coatings are wetting agent, dispersant, film-forming agent, thickener, anti settling agent, defoamer, mildew inhibitor, etc As an auxiliary, it must meet the following requirements 1 It has good compatibility with the base material and can not produce flocculation or other chemical reactions It is not sensitive to the pH value of the system or other salts, and cannot affect the performance of the coating and coating During the effective service life of building coating after construction, there will be no degradation of coating due to precipitation and other phenomena 2 Low toxic or non-toxic, construction coatings in the process of construction or use of contact with the human body more opportunities, most of the current water-based coating itself low toxic or non-toxic products, so it is required that the additives used must also be low toxic or non-toxic 3 High efficiency, compared with other components used in architectural coatings, the amount of additives is less, usually less than 1%, so it requires high efficiency 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,
