Yongkang spray powder manufacturer takes you to understand what spray is

Spray coating is a surface treatment method of spraying plastic powder onto parts. Spray coating, also known as electrostatic powder coating, is a commonly used decorative technique for metal surface treatment internationally since the 1980s. Compared with ordinary spray painting surface treatment, this technology has advantages in advanced technology, energy saving and high efficiency, safety and reliability, and bright color. Therefore, it is often applied in the fields of light industry and home decoration. Its working principle is to charge plastic powder through a high-voltage electrostatic device, and under the action of an electric field, spray the coating onto the surface of the workpiece. The powder will be uniformly adsorbed on the surface of the workpiece, forming a powdery coating; After high-temperature baking, the powder coating will level and solidify, and the plastic particles will melt into a dense layer of final protective coating with different effects; Firmly adhere to the surface of the workpiece.
