powder coating better than liquid 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 without the use of volatile organic solvents and water solvent, so paint is a kind of inorganic solvent based paint, greatly reducing the potential safety problems caused by the solvent, such as because of containing organic solvent caused by operating personnel organic solvent poisoning or as organic solvent caused by fire disaster. From the last century five, sixty years of paint available so far, there has not 

been a major security incidents caused by paint.

Powder coating in automotive parts application began in the middle of the 1970s, such as for suspension components, engine blank body, oil filter, air purifier and brake pipe and other components, the preferred varieties is epoxy coating; coating for doors and windows components, windshield wipers, luggage rack, Paul insurance bar etc. external metal components, polyester or acrylic for system optimization. These powder coatings are usually low gloss black or 

dark gray products. Epoxy coatings endow the coating with excellent adhesion, mechanical properties, resistance to shock resistance, chemical resistance and corrosion resistance, which can be achieved after 15min curing at low temperature.

Fine particles of powder coating 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: powder coating process due to pigment produced condensates: part of the resin curing reaction gel particles in the melt mixing process in manufacturing, these particles will form a coating on the particles.
