Common knowledge of coating: three tips for choosing water-soluble coating

Core tip: water soluble coating and latex paint is relatively poor in friction resistance After only 10 times of friction, it is easy to have peeling, falling off, cracking, blistering and other phenomena ★ see the advantages clearly Water soluble coating is a kind of coating with water as solvent or dispersion medium The reason why it is water-soluble is that there are a certain number of strong hydrophilic groups in the polymer molecular chain, such as hydroxyl group Because the water-soluble coating uses water as solvent, it is not easy to cause fire hazard in the construction process; moreover, it contains no toxic gases such as benzene and other organic solvents, causing damage to people and the environment 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: water soluble paint and latex paint is relatively poor in friction resistance After only 10 times of friction, it is easy to have peeling, falling off, cracking, blistering and other phenomena ★ see the advantages clearly The water-soluble coating is the coating with water as solvent or dispersion medium The reason why it is water-soluble is that there are a certain number of strong hydrophilic groups in the polymer molecular chain, such as hydroxyl group Because the water-soluble coating uses water as the solvent, it is not easy to cause fire hazard in the construction process; moreover, it contains no toxic gases such as benzene and other organic solvents, causing little harm to people and the environment; in addition, its workpieces can be constructed without waiting for complete drying after oil removal, rust removal, phosphating and other treatment, which is more beneficial to the progress of the construction period ★ understand the disadvantages because the water-soluble coating uses water as the solvent, because of the high latent heat of evaporation, the drying time of the paint film and the drying time at room temperature must be increased, and there will be some restrictions on the application of such as wood, paper, etc In addition, the use of organic amines as neutralizers will cause certain water pollution ★ inspection method the owner can open the end of the water-soluble coating when purchasing, stir the water-soluble coating with a wooden stick to see if there is any caking inside, if there is caking, it means that the quality of the coating is not good A little paint can also be picked out with a wooden stick to see its downflow state If the water-soluble paint is continuous downflow in the form of filaments, rather than a combination of pieces, it means that the water-soluble paint has a good fluidity and decorative effect Due to the existence of a large number of hydrophilic genes and low molecular weight, the water-soluble coating has poor corrosion resistance compared with the same type of solvent coating The owner shall fully understand its performance when purchasing 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,
