Abstract

Disclosed herein is an electrostatic spray-painting method and an electrostatic spray-painting ap-paratus. This method basically comprises the steps of supplying a predetermined amount of water-based paint to an intermediate reservoir from a grounded water-based paint feed source through a feed line having an electrically-insulated portion formed in at least a part thereof; washing the electrically-insulated por-tion with deionized water having specific electric con-ductivity lower than given specific electric con-ductivity; removing the deionized water remaining in the electrically-insulated portion by using dry air after completion of the washing step so as to electri-cally insulate the water-based paint feed source from the intermediate reservoir; and supplying the water-based paint to a spray gun from the intermediate reser-voir under the condition of the water-based paint feed source and the intermediate reservoir being electrical-ly insulated from each other, thereby carrying out an electrostatic spray coating process. The above appara-tus basically comprises a color changeover valve me-chanism, a first directional control valve, a block line, a second directional control valve, an intermedi-ate reservoir, a waste-liquid tank, a spray gun, and a high-voltage applying device.
