Funkensicherer rotierender Zerstäuber

摘要

A rotary atomizer (66) comprises an inside surface onto which a coating material is deposited, an opposite outside surface (90) and a discharge zone adjacent the rotary atomizer's inside and outside surfaces, coating material being discharged from the discharge zone, first means (84) for rotating the rotary atomizer (66), a housing (64) for substantially surrounding and housing the rotary atomizer (66) except for a region of the rotary atomizer adjacent and including the discharge zone, the housing (64) including an inside surface (62), an outside surface and an opening adjacent the inside and outside surfaces of the housing, the inside surface of the housing and the outside surface of the rotary atomizer both being treated so as to be electrically non-insulative, and second means for maintaining an electrostatic potential difference across the electrically non-insulative inside surface of the housing (64) and an article to be coated by material atomized by the rotary atomizer (66).
