涂装车间前处理电泳工艺细菌微生物治理

Countermeasures for Bacteria and Microbes Multiplying at Pretreatment and E-Coat Process in Paint Shop

为解决细菌微生物孳生形成的微生物粘泥粘附在车身上影响电泳质量问题,以某涂装车间前处理磷化和电泳工艺过程中细菌微生物孳生问题及治理方法为例,从生产期预防和停产期维保的2个维度对细菌微生物的治理进行了探索,生产期预防主要采用提高水洗工位更新率和提高过滤效率的方法来避免微生物粘泥污染车身。停产期维保采用拆开深度清洁,结合杀菌剂杀菌+热水清洗+专用清洗工具清洁相结合的方法,共同形成了有效的治理策略。

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.
