Abstract
PURPOSE: To suppress the compsn. fluctuations of an electrodeposition paint bath effectvely and to perform stable painting by removing the electrodeposition paint in a cathode zone covered with a masking material permeating polycarboxylic acid resin components in an electrodeposition painting bath tank to the outside of the bath tank, mixing the same with replenishing paint of a prescribed degree of neutralization under agitation and supplying this to an anode zone.
CONSTITUTION: A masking material 3 permeating the above-described resin components is disposed on the surface of a cathode 2 provided on the side wall of an electrodeposition painting bath tank 1 in such a way as to cover the contact surface of the cathode 2 with the paint liquid, thereby devide the inside of the tank 1 into a cathode zone 4 and an anode zone 5. The electrodeposition paint of a high neutralizer concn. in the zone 4 accumulated with the neutralizer as a result of continuous electrodeposition painting is removed arbitrarily to the outside of the tank 1, and is transferred into a diluting tank 8, after which this is utilized for dissolution and dilution of paint 7 for replenishing consisting essentially of a polycarboxylic acid resin of 0.1W0.5 degree of neutralization. As a result, the dissolution and dilution of the paint for replenishing are simple, the compsn. fluctuations of the electrodeposition paint bath are controlled to a min. and the electrodeposition painting exhibiting a superior paint film appearance is accomplished stably.
