powder coating is solid

Part of the resin curing reaction gel particles in the melt mixing process, the particles will form a coating on the particles. In the construction of electrostatic spraying, the problem of 

environmental dust should be paid enough attention. Dust from the air, peeling off the operating personnel work tape bag recycling equipment on the fiber and curing equipment, the dust in 

electrostatic powder spraying process will cause film pollution and particles. In order to improve the multi function of powder coating, according to customer's preferences to adjust the color, gloss and surface flatness, and even special metal powder coating and some special wrinkle powder coating. With the environmental protection act of the organic volatile matter (VOC) content in the atmosphere of the increasingly stringent requirements, the coating industry to seek a variety of ways to improve the coating technology to reduce the pollution of the environment. After a long period of experiments and tests, finally found that "powder coating" is the most ideal coating technology that can be achieved at present.

Powder coating is one hundred percent of solid powder coating, can be fully automatic spraying. An excess or spray the powder coating, through the recovery system and achieve the purpose of recycling, therefore powder coating almost up to 100% utilization rate, making coating industry reduce waste processing. At the same time, the degree of pollution of the environment reduced to a minimum. The reason for the coating particles produced in powder coatings in the gel, causing insoluble particles and impurities. Fine particles of powder coatings in easy accumulation change the site of airflow direction in the coating device and spray head or in the pipeline, when accumulated to a certain degree the state of aggregation spray out attachment is painted above, baking does not melt and become diameter for 0.5-3 degree of particles attached in the spraying chamber wall and recycling equipment gelatinizer: manufacturing powder coating process due to a 

pigment produced condensates. Polyurethane powder coatings as powder coating of a, with many excellent properties, the coating of high gloss, good decorative performance, strong resistance, good adhesion. At the same time, it has good weather resistance, corrosion resistance, electrical properties and mechanical properties, can say which take into account the advantages of epoxy and acrylic powder coating, but also have advantages of non-toxic in comparison with pure polyester powder coatings.
