1, the advantage is that before coating the surface of the enterprise workpiece oxidized skin, rust, grease, dust, dirt, etc. to remove the clean process, so that the coating powder and metal surfaces firmly combined, strong adhesion, in order to obtain high-quality products, to extend the service life of the product. Powder electrostatic spraying equipment, powder coating has a good economy, no environmental pollution, high efficiency, three times after spraying so that the thickness of the coating can reach within 50μ. Powder electrostatic spraying equipment mainly includes powder spraying room, high voltage electrostatic cooling system, electrostatic spray gun device, paint supply system, devices and components.
2, the disadvantage is that the powder coating line equipment is very complex.
