Know yourself as well as the enemy can ever victorious, this sentence where all can, as Ji'nan electrostatic spray, understand its basic principle can be better to understand, then, what is the basic principle of it?
As a result of Ji'nan electrostatic spray process is the use of corona discharge phenomenon, so that the powder coatings adsorbed on the workpiece. Plastic electrostatic spray, is the application of high voltage electrostatic, between the plastic powder spraying gun and the metal workpiece, forming a high voltage corona discharge field. When a special spray gun connected with the high-voltage negative electrode connected to the positive electrode workpiece at gunpoint, and fall to the ground, then consists of an electrostatic discharge circuit.
Because the plastic powder is insulated, so he took charge in addition to close to the workpiece surface portion of the ground is discharge, the rest of the agglomeration, with the increase of spray powder agglomeration, the charge is also more and more, the negative potential increase, will eventually make the workpiece is no longer the powder. And then through the electrostatic spray equipment for heating, which makes the powder melting, forming a layer with a certain luster, uniform coating on the surface of the workpiece, to achieve the purpose of protection and decoration.
In fact, there is a significant advantage of Ji'nan electrostatic spray, is able to overcome spraying in corners and shadow zone. In addition, the general plastic powder with automatic levelling properties in the molten state, was sprayed workpiece in the process of drying room heating melting, by plastic automatic leveling characteristics, will the pinhole parts make up. Therefore, the surface of the workpiece is relatively uniform.
