In order to address the issue of microbes slimegenerated by bacteria and microbial breeding sticking on the car bodies and affect E-coat quality, taking bacteria and microbial breeding in pretreatment phosphorization and E-coat process of a painting shop and management as example, this article explores the management of bacteria and microbes from 2 aspects including precautions during production and maintenance during shutdown. Precaution during production refers to improving water rinsing station turnover rate and improving filtration efficiency to prevent microbe slime from contaminating car bodies, whereas maintenance during shutdown refers to dismantling and deep cleaning, combined with bactericide, hot water rinsing and special rinsing tool to form an effective management strategy.
