Main varieties and application range of powder coatings
2019-10-02 07:04:58
The main varieties of powder coatings are epoxy resin, polyester, acrylic and polyurethane. At present, powder coatings are used in the automotive industry for the coating of automotive engines, chassis, wheels, filters, joysticks, mirrors, wipers and horns, but they are basically black, only a part of which is transparent. coating.
In foreign countries, transparent powder coatings have been applied to the cover of car bodies and the cover of vehicles. Automobiles have high requirements on coatings, not only require good physical and chemical properties, but also require a smooth, smooth and high-gloss appearance. For cars, it is required to be bright as a mirror. Although powder coatings have good physical and chemical properties, they are coated. There is always a difference in appearance compared to solvent-based coatings, so the car's outer casing has not been heavily coated with powder coatings. In recent years, foreign countries have made a lot of efforts and research work for the application of powder coatings in automobile painting, and have made great progress in the synthesis of resins, the manufacture of powders and the coating technology. BKG of the United States refers to the application of high-infrared heating technology to the coating of powder coatings to heat the metal first, then solidifies the powder coating with the heat of the metal substrate, and solidifies the epoxy/polyester powder sprayed on the 1mm steel plate within 9 seconds. Paint, while general hot air circulation or far infrared equipment takes 18 minutes to cure. The cure rate is increased by a factor of 120. The application of high-infrared heating technology can greatly improve the production efficiency, reduce the length of the drying tunnel, save investment, and more importantly, improve the flat brightness of the coating surface.
There are not many applications of powder coatings in automotive coatings in China. There are some constraints on the variety, quality and technology of powder coatings. The variety structure of powder coatings in China is not conducive to the coating of automobiles. Automotive coatings have high requirements on weather resistance. However, most of the powder coating products in China are epoxy D polyester mixed powders and epoxy powders, which are suitable for outdoor use. There are not many products of modified epoxy powder, polyurethane powder, [email protected] polyester powder and acrylic powder, and there are still many problems in quality. However, in the United States, the production of powder coatings for outdoor use accounts for more than half of the total output. It is obvious that the variety structure of powder coatings in China is quite different from that of developed western countries. In addition, there are also coating equipment and baking equipment. The gap between quality and scale. The application of powder coatings in the automotive industry is quite different from that of the appliance industry.

Silicon Carbide is the only chemical compound of carbon and silicon. It was originally produced by a high temperature electro-chemical reaction of sand and carbon. Silicon carbide is an excellent abrasive and has been produced and made into grinding wheels and other abrasive products for over one hundred years. Today the material has been developed into a high quality technical grade ceramic with very good mechanical properties. It is used in abrasives, refractories, ceramics, and numerous high-performance applications. The material can also be made an electrical conductor and has applications in resistance heating, flame igniters and electronic components. Structural and wear applications are constantly developing.
It is produced from quartz sand and high quality anthracite under high temperature in an electric resistance furnace.If looks black and has a microhardness of 2800-3300kg\mm2,being used for produce the abrasive tools.It is also fit for process the grind metals and non-metals material of low tensile strength,such as grey cast iron,brass,aluminium ,stone,leather and hard rubber ect.Also can be used as refractory materials and in electronic industry.Silicon Carbide
