The powder electrostatic spray gun is mainly composed of a powder supply barrel, a powder spray gun and a controller. It is a special spray gun for electrostatic spraying of coatings and powder coatings. It is both a coating atomizer and an electrostatic electrode generator.
Powder spraying has been widely used as an important means of surface treatment since it came out.
Powder is different from traditional solvent based coatings. There is no polluting gas or liquid discharged during the coating process. It is very environmentally friendly for the processing environment or the processing itself, and has become one of the indispensable means in the surface treatment industry.
The powder needs to be adsorbed on the workpiece with electric charge, so as to form an effective coating to protect and decorate the workpiece.
Powder spray guns that can generate high-voltage static electricity are usually used as production tools for powder coating. Such spray guns will generate high-voltage and low current high-voltage electric fields, in which the powder particles will move with negative charges, and then firmly adhere to the workpiece to be coated. Such a process is usually called powder electrostatic spraying.
