Abstract
Based on the structural characteristics of painting equipment in metal jewelry industry,the performance of paint mist flocculant was investigated through sampling test of circulating water and field pilot test,and the optimal concentration and proportion of paint mist flocculant was selected,so as to achieve the purpose of complete debonding and flocculation of overspray paint.After field testing,the optimal pH control range was 8.5~9.5,the additive concentration of paint mist flocculant RC-2502A was 0.25%,the additive concentration of RC-2502C was 1.45%,which had the best treatment effect on paint slag.The problems of circulating pump and pipeline blockage and the pungent smell in the painting workshop which had existed for a long time before was obviously improved.After long-term use,the circulating water system equipment was running stably,so the paint mist flocculants were expected to be widely promoted and applied in the spraying system of jewelry industry.
