Description

TECHNICAL FIELD

[0002] Plastic spraying refers to charging plastic powder by using an electrostatic generator, which is a surface treatment method of spraying plastic powder on parts. Its working principle is to charge the plastic powder through high-voltage electrostatic equipment, and to spray the coating to the surface of the workpiece under the action of the electric field. The powder will be uniformly adsorbed on the surface of the workpiece to form a powdery coating. After the powdery coating is baked at high temperature, the plastic particles will melt into a layer of final protective coating with different effects. The protective coating is firmly attached to the surface of the workpiece. In the production of guardrails, it is necessary to perform plastic spraying on the guardrails, which are hung on the hanging frame for plastic spraying.
