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.
