Dusting process, also known as powder coating, is the rapid development of the past few decades a new coating process, the use of raw materials is plastic powder. As early as the four decades some countries began to study the experiment, but progress is slow. In 1954, Germany, Germany will be coated with polyethylene fluidized bed with a successful process, in 1962 France's Simmons invented powder electrostatic spraying, the powder coating began in the production of formal use in recent years due to the country on the environment Protection of the attention of the water and the atmosphere is not polluted powder coating, has been rapid development.
The process highlights the advantages
1, a coating can be a thick coating, for example, coated with 100 ~ 300μm coating, with the general common solvent coating, about 4 to 6 times the coating, and powder coating can be achieved once the thickness The The corrosion resistance of the coating is very good.
2, powder coating without solvent, no waste pollution, improve the labor hygiene conditions.
3, the use of powder electrostatic spraying and other new technology, high efficiency, suitable for automatic assembly line coating, powder utilization is high, recyclable use.
4, in addition to thermosetting epoxy, polyester, acrylic, there are a large number of thermoplastic grease can be used as powder coatings, such as polyethylene, polypropylene, polystyrene, fluorinated polyether, nylon, polycarbonate and various Fluorine-containing resin and so on.
Powder coatings began to be used for protection and electrical aspects, with the development of technology, has been widely used in the automotive industry, electrical insulation, corrosion-resistant chemical pumps, valves, cylinders, pipes, outside the steel components, steel furniture, Surface coating. China since the sixties began powder coating experimental research, electrostatic spraying equipment, and in the production of the application. Development has been widely used.
