[0002] Electrostatic powder spray gun is a key spraying equipment in powder spraying equipment. Its main working principle is to use a high-voltage electrostatic generator to ionize the air around the powder spray gun head to generate a negative electrostatic magnetic field, so that the powder is adsorbed onto the workpiece with a positive electrode to be coated. It directly determines the quality of the workpiece coating and is a key factor in determining the level of the process.
