In the electrostatic spraying process, the mechanically atomized paint particles repel each other after being negatively charged and become more dispersed and uniform. Therefore, the formed coating film is very fine and has good appearance and decoration.
Due to the tip effect of the charge, the charge density of the corners of the workpiece is high, and the deposited coating is thick. Under the action of surface tension, the coating film is still thick enough after drying, so the spraying effect on the corners of the light housing is good.
The use of electrostatic spraying makes the shell more corrosion resistant and can extend the life of the lamp.
