Product Description:
Powder coating is a new process of coating technology. Because of its good economic performance, no environmental pollution, high efficiency and so on, it has replaced the solvent coating process in many aspects. The main coating methods are electrostatic spraying method, fluidized bed method, electrostatic shock coating method, dispersion method, dissolving method, friction belt powder coating method. Screen-type powder coating method and powder aerodynamics spray channel method and so on.
Different powder coating methods have different characteristics and different application range, but at present, the powder electrostatic spraying method is widely usedPowder electrostatic spraying is charged powder particles under the action of electric field force. A coating method by which the surface of the work piece is adsorbed to form a coating by leveling the solidification.
During working, the powder is mixed with air in the powder feeder and is fed into the powder spray gun. The high voltage generated by the HV electrostatic generator is connected to the interior or front of the powder gun. The powder particles are charged at the interior or outlet of the gun (depending on the structure of the gun, under the action of static electricity). The powder particles are directed to the workpiece to be coated.
Not only can spray to the front of the workpiece, it also can attract to the back of the workpiece. When the powder attached to the workpiece is more than a certain thickness, electrostatic repulsion occurs, and the later powder is not easy to adsorb. To achieve uniform film thickness, spraying the work, in the curing furnace, powder laminar flat, the formation of a uniform coating.
Application scope: lighting, electrical appliances, furniture lampshade, hardware machinery, distribution cabinet, frame, laser frame, aluminum alloy window frame, trinket, sports equipment, auto and motorcycle accessories, metal stamping parts. Aluminum alloy die castings, etc.
Pretreatment is the process of thoroughly cleaning the dirt on the surface of workpiece, such as oxidized skin, rust, grease, dust and so on before painting, so that the coated powder is firmly bound to the metal surface, and the adhesion is strong, thus making the product obtain high quality. Extend the service life of the product.
