Electrostatic spraying charges paint particles through a high-voltage electrostatic field and adsorbs them onto the surface of the workpiece, achieving an efficient and uniform coating. To enhance efficiency, the following techniques need to be mastered: Adjust the distance between the spray gun and the workpiece (25-30 centimeters) to avoid sagging when too close or missed spraying when too far.

Control the voltage between 60 and 100kV to prevent pinholes in the coating.

Select highly fluid powder to reduce blockage;

Optimize the temperature and humidity of the spraying environment to reduce the influence of dust.

Introduce automated equipment (such as robot spray guns) and intelligent monitoring systems to enhance accuracy and speed;

Implement a powder recovery system to reduce waste and cut costs. Regular maintenance of equipment (such as high-voltage power supplies and spray guns) can ensure stable operation. Through parameter optimization, equipment upgrading and process management, the efficiency of electrostatic spraying can be increased by 30% to 50%, and the utilization rate of coatings can reach over 90%, facilitating green production and cost control.
