The process goes like this: Powder coating is fed into the spray gun by the powder supply system through compressed air gas, and the high pressure generated by the high voltage electrostatic generator is added to the front end of the spray gun. Due to corona discharge, a dense charge is generated near it. When the powder is sprayed by the gun mouth, charged coating particles are formed, which are sucked into the workpiece with opposite polarity. When a certain thickness is reached, due to the electrostatic repulsion, it does not continue to adsorb, so that the whole workpiece obtains a certain thickness of the powder coating, and then the powder is heated to melt, level, and cure, that is, a hard coating film is formed on the surface of the workpiece.
The electrostatic spray cabinet, powder recovery cabinet, blast furnace curing furnace and other machinery used in the production process are all sold, and we can come to consult!
