Electrostatic powder coating is one of the major reforms of coating technology in recent years. It has developed rapidly with the characteristics of no pollution, saving resources and high efficiency, and has become the main way to replace solvent coating. Electrostatic powder coating is a method that USES the powder coating to be charged by induction under the action of high voltage electrostatic, and to make the powder coating adsorb evenly on the surface of the workpiece to be coated under the action of electric field force, and then to achieve the purpose of coating by means of melt leveling and remaining into a film. In order to adapt to the market demand, many domestic manufacturers have launched a single model suitable for manual operation electrostatic powder spraying equipment. This type of single-model equipment is generally composed of electrostatic powder spray gun, powder pump body, high-voltage electrostatic generator circuit and powder supply system. The high-voltage electrostatic generating circuit generates 30-90kv continuously adjustable electrostatic voltage after modulating and rectifying the voltage doubling of mains electricity. The existing high pressure gun module for electrostatic powder spraying is not safe to use, and the existing high pressure gun module for electrostatic powder spraying is not heat dissipation.
