COATING SLAG SEDIMENTING AGENT, TREATING AGENT FOR COATING BOOTH CIRCULATION WATER CONTAINING COATING SLAG SEDIMENTING AGENT AND METHOD OF TREATING COATING BOOTH CIRCULATION WATER USING THEM

摘要

PROBLEM TO BE SOLVED: To provide treating agents for coating booth circulation water capable of quickly sedimenting/separating the coating slag mixed in the coating booth circulation water and recovering without fail and with ease the uncoated coating material left in the coating booth circulation water and a method of treating the coating booth circulation water using them.;SOLUTION: The coating slag sedimenting agent, which is for sedimenting and treating the coating slag in the coating booth circulation water, contains the coating slag powder prepared by hardening and crushing the coating slag recovered in advance from the coating booth circulation water and is for wet coating booth circulation water. The coating booth circulation water treating agent, which is for sedimenting and treating the coating slag in the coating booth circulation water, contains the coating slag powder prepared by hardening and crushing the coating slag recovered in advance from the coating booth circulation water and a blocking resistance treating agent and is for wet coating booth circulation water. As for the treating method for the coating slag which is contained in the coating booth circulation water and collects uncoated paint left in the coating booth, the above said coating slag sedimenting agent containing the coating slag powder prepared by hardening and crushing the coating slag recovered in advance from the coating booth circulation water is added to the coating booth circulation water, the coating slag is sedimented and removed from the coating booth circulation water, and the coating booth circulation water is used for circulation.;COPYRIGHT: (C)2005,JPO&NCIPI
