COATING POWDER ADHESION SUPPRESSING METHOD, COATING POWDER CONVEYING METHOD, COATING POWDER CONVEYING SYSTEM, COATING DEVICE, AND COATING FILM FORMING METHOD

摘要

PROBLEM TO BE SOLVED: To provide a coating powder adhesion suppressing method, a coating powder conveying method, a coating powder conveying system, a coating device, and a coating film forming method for uniformly keeping the amount of the conveyance of coating powder for a long time by suppressing the adhesion of the coating powder on a wall surface of a conveying path.;SOLUTION: A voltage is applied to two first and second electrodes 35 and 36 arranged at the outer periphery of a conveying tube 27 with the conveying path 26 through which carrier gas 25 flows, thereby generating an electric field E1 in the conveying path 26. The coating powder 5 is made to fly and move in a direction different from the flowing direction of the carrier gas 25 by the electric field E1, and the coating powder 5 is pneumatically conveyed while suppressing the adhesion of the coating powder 5 on the wall surface 26h of the conveying path 26.;COPYRIGHT: (C)2011,JPO&INPIT
