METHOD FOR ELECTROSTATIC COATING OF POWDER COATING AND ELECTROSTATIC COATING MACHINE FOR POWDER COATING

摘要

PURPOSE: To perform electrostatic coating with high electrostatically charging rate, accordingly with high coating efficiency, and uniformly regardless of unevenness of the surface of an article to be coated by using a powder coating. ;CONSTITUTION: A main discharging electrode 2 on which a DC high electric voltage is applied and a pulse discharging electrode 6 with the same polarity as that of the main discharging electrode 2 and on which a DC pulse high electric voltage is applied are arranged to generate corona discharge between both electrodes and a powder coating is passed through between both electrodes to charge it electrostatically.;COPYRIGHT: (C)1996,JPO
