Generally, when parts have internal corners or an odd geometry, due to how the electrostatics travel through the metal, the powder will not apply to these areas easily. This is called a Faraday Cage. Within these zones, the resistance to electrical forces is much greater than on all other surfaces.
Powder coating isn't solely used in construction. If you look at your home appliances, you will see that they come with high quality painting. Mostly, it is scratch resistant and can even withstand a dent without chipping off. This is because they have been powder-coated.Powder coating makes painted
Powder coating is applied in a unique way, and the technique lends a host of benefits and features to the application. A few of the benefits include: durability, longevity, variety, less toxic, cost-efficient, etc.
The main function of spray gun is to make the spray powder have a good atomization state and fully charged to ensure that the powder can be uniformly and efficiently adsorbed to the surface of workpiece.
Both tribo and corona powder coating have been commonly adopted for particle charging in the powder coating industry. Depending on the application, tribo or corona powder coating technologies are used for different powder coating productions.
Powder Coating spray gun contains high-voltage cascade could improve the safety performance and working efficiency, reduce powder consumption and save cost.
