The difference between electrophoresis and spray paint

Electrophoretic coating is to immerse the conductive substrate in an electrophoretic coating tank filled with water and diluted with a relatively low concentration as the anode (or cathode), and set a corresponding cathode (or anode) in the tank. A coating method in which a direct current is applied between the two poles for a certain period of time, and a uniform, water-insoluble coating film is deposited on the coated object.

The electrostatic spraying technology uses a powder-air mixture. A small fluidized bed is provided in the powder feed hopper to form a powder-air mixture. In some cases, the vibration of the feed hopper helps prevent clogging or accumulation of powder before it enters the conveyor line. The powder is delivered to the spray gun through a hose, and the nozzle of the spray gun forms a charged electrode due to the input of high-voltage direct current.
