powder coating will replace liquid coating

The application field of powder coating and coating technology is increasing day by day. 


According to reports, due to the enormous environmental pressure, powder coating has become 


the mainstream of the current mainstream, with the improvement of powder coating and 


coating technology, the application of powder coating will be greater.

The improvement of 


powder coating and coating technology is mainly due to the growth of the automotive 


industry, household appliance industry and general industry, including the development of 


raw material, powder and coating technology. Application of powder coating in the 


automotive industry continues to expand, car interiors, chassis, wheels and body are 


beginning to use powder coating. For powder coating technical improvement including 


automobile: transparent powder transparency, adhesion, leveling and anti UV: in the premise 


of powder coating appearance and performance as much as possible under lower curing 


temperature; and coating technology (such as robot technology, flow control technology and 


the high rate of the powder technology, etc.).

According to reports, powder coating coated 


metal plate (coil) used in the home appliance industry, the rapid growth of demand, powder 


coating in 25 ~ 60s to complete the whole process of melting, flow and solidification, and 


maintain a good appearance and a variety of resistance. Powder coating for household 


appliances must have a certain degree of formability, the degree of molding depends on the 


end use. Coated sheet should be stacked together, the speed of the coating line should 


reach 30 to 80fpm, the line speed of the coil coating should reach 100fpm. In addition, air 


flow control (or reduction), powder rate or charge transfer rate should be controlled in 


the best condition.

In the high speed improvement of coating line curing film appearance is 


the main direction of the improved appliance technology of powder coating, it relates to 


the infrared wavelength / light intensity and coating and substrate matching problem, fast 


flow convection heating and induction heating curing powder coating surface, good 


continuity, and the curing procedure curing system cleanliness.

The development of the 


automotive industry and the appliance industry to promote the development of special powder 


coating system and coating technology, the application of special powder coating is 


applicable to different processes in general industrial coating has grown gradually into 


previously difficult to get involved in the field (due to color to ask too much, too fast, 


paint coating of serious bleeding too much coating, etc.). In the general industrial 


coating market powder coating can provide a variety of batches of products to meet the 


needs of many small customers become another major highlight. The global coating network 


learned increasing equipment suppliers and raw materials suppliers have prompted many 


regional paint suppliers add powder coating production line, at the same time, the European 


market has been mature in powder coating raw materials and new coating equipment available. 


In short, the increase in the number of suppliers for small and medium sized powder users 


is the most favorable, they can get a stable price of raw materials, the product is more 


practical. But the development of large powder customers is often only a small number of 


specific suppliers to benefit, so that they and the powder coating, painting process, as 


well as the end user of a greater degree of correlation.

Powder coating is a new type of 


100% solid powder coating without solvent. With no solvent, no pollution, recycling, 


environmental protection, saving energy and resources, reduce labor intensity and high 


mechanical strength of the film.
