A DEVICE FOR POWDER PAINTING, AND A PAINTING PROCESS THAT USES SAID DEVICE

摘要

Described herein is a device and a process that uses said device for powder painting, comprising an electrode for the generation of electrostatic charges supplied by a voltage generator; the device further comprises a body made of dielectric material having a cavity in which said electrode is housed. Said cavity is designed to confine therein electrical charges generated by the electrode, and the body made of dielectric material comprises an opening that sets the inside of the cavity in communication with the external environment and enables controlled emission, within the cavity outwards, of said electrical charges.
