Abstract
The invention discloses an electrostatic coating method for polyether-ether-ketone powder. According to the electrostatic coating method for the polyether-ether-ketone powder, an electrostatic spraying device is adopted, physical and chemical coating particles take negative charges in a high-voltage direct-current electric field and flow to a workpiece surface with positive charges directionally under the action of an electrostatic field, and a layer of even and firm thin film is formed by neutralizing and deposition. The electrostatic coating method for the polyether-ether-ketone powder achieves good film coating performance, lowers the degree of pollution to the environment, saves coating materials, enables a coating process to be mechanical and continuous, reduces the rejection rate, improves labor productivity, improves working conditions, thereby obtaining considerable social and economic benefits.
