Powder electrostatic spraying is the principle of using high voltage electrostatic corona electric field. Connect a high-voltage negative electrode to the metal deflector on the head of the spray gun, and the sprayed workpiece is grounded to form a positive electrode, so that a strong electrostatic electric field is formed between the spray gun and the workpiece. When the compressed air as the carrier gas sends powder paint from the powder supply barrel to the guide bar of the spray gun through the powder tube, the guide bar is connected to the corona discharge generated by the high-voltage negative electrode, and a dense negative charge is generated in the vicinity The powder is negatively charged and enters an electrostatic field with a high electric field strength. Under the dual action of electrostatic force and carrier gas, the powder evenly flies to the surface of the grounded workpiece to form a thick and uniform powder layer, which is then heated and solidified. Durable coating.

The color of electrophoresis aluminum is relatively good, electrophoresis is a relatively expensive material, and it is easy to distinguish the poor quality when it is burned, broken with a hammer, and will generally lose paint.
Good general use electrophoresis, although plastic steel is very cheap, generally need to be replaced once in 3~10 years
