Technical Support for Electrostatic Powder Spray Gun

An electrostatic powder spray gun uses the principles of electrostatics to evenly coat a surface with powder paint. The working process mainly involves four steps: powder feeding, electrostatic charging, powder spraying, and curing.

: The powder paint is conveyed to the spray gun through the powder feeding system. This system typically consists of a powder feeder and delivery lines, maintaining a consistent pressure and flow rate of the powder paint.

: A high-voltage electrostatic generator inside the spray gun creates a high-voltage electrostatic field. As the powder paint passes through the gun, it is charged by a corona discharge device (electrode at the nozzle), usually acquiring a negative charge.

: The charged powder particles are sprayed out of the gun and move towards the workpiece under the influence of the electrostatic field. Since the workpiece is grounded, it creates a positive potential relative to the negatively charged powder particles, attracting them to its surface.

: The powder coating on the workpiece needs to be cured by heating. The workpiece is placed in an oven, where the powder paint melts, flows, and solidifies into a durable coating at a temperature typically between 180°C and 200°C.

Electrostatic powder spray guns are widely used in various industries, primarily including:

Due to its high efficiency, environmental friendliness, and superior coating quality, electrostatic powder coating technology has become the mainstream choice for modern industrial coatings. As technology continues to advance and application areas expand, electrostatic powder spray guns will play an even more critical role in industrial coatings in the future. Developing more efficient and intelligent electrostatic powder coating equipment will provide higher quality surface treatment solutions for various industries and drive continuous technological advancement in the industry.
