Common knowledge of coating: the influence of low temperature on coating construction

Core tip: our coating is composed of a variety of chemical materials At low temperature, the performance of chemical materials will change, which will also affect the coating construction Low temperature affects the film-forming and drying of the coating When the paint is applied to the surface of furniture to form a paint film, the resin in the paint film will have a cross-linking reaction The low temperature will weaken the molecular activity energy and slow down the cross-linking reaction speed; the solvent in the paint film needs a certain amount of energy to volatilize, and the low temperature also makes the solvent volatilize slowly, which is directly related to the temperature For nitrolacquer, pay attention to the control of air humidity in winter, which affects the construction of nitrolacquer Paint knowledge how about Akzo Nobel Powder Coating Recommended introduction: powder coating is a kind of coating with different form from general coating, which is in powder form It is a new type of coating, because of its own advantages and more and more known by people Let's introduce Akzo Nobel Powder coating Akzo Nobel Powder coating is a cost-effective coating solution, which can be applied to different kinds of products After the treatment of static electricity and fire baking, a tough and durable coating surface will be formed, with the least impact on the environment Since the introduction of this technology, powder coating has been able to continue to maintain the Paint Home News: our paint is composed of a variety of chemical materials At low temperature, the performance of chemical materials will change, which will also have a certain impact on the paint construction Low temperature affects the film-forming and drying of the coating When the paint is applied to the surface of furniture to form a paint film, the resin in the paint film will have a cross-linking reaction The low temperature will weaken the molecular activity energy and slow down the cross-linking reaction speed; the solvent in the paint film needs a certain amount of energy to volatilize, and the low temperature also makes the solvent volatilize slowly, which is directly related to the temperature For nitrocellulose paint, pay attention to the control of air humidity in winter Humidity is an important factor affecting the construction of nitrocellulose paint The moisture in the air inhibits the evaporation of solvent in the paint film In addition, the evaporation of solvent will take away the heat of the paint film, so that the temperature on the surface of the paint film will drop The temperature on the surface of the paint film will be lower than the surrounding temperature Due to the large indoor temperature difference after heating, it is easy to cause the evaporation of solvent in the air The water vapor condenses on the paint film and makes it white 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,
