Powder spraying equipment is one of the tools necessary for electrostatic powder spraying. It can effectively connect a series of processes such as spraying, recycling, and powder supply, so as to give higher efficiency to the powder spraying process.

1.The advantages of powder coating

1) There is no solvent in the coating and all are solids, which can reduce environmental pollution and improve the coating construction conditions.

2) The thickness of a single spray can reach 50 ~ 300m, which can simplify the construction process, shorten the production cycle, reduce production costs, improve work efficiency, ensure the quality of a coating film, and avoid defects such as sagging, accumulation, and pores after coating. The generation.

3) The paint loss is small, and the recovery rate of solid powder can reach more than 90%.

2. Disadvantages of unpainted powder

Disadvantages of powder coating: It is difficult to obtain a thin coating film; color matching, repair, and coating of complex-shaped workpieces are difficult, and the coating equipment is also more complicated.

Powder coating process: surface pretreatment → cover or cover the parts that do not need to be painted → preheat powder coating of the workpiece → baking.
