汽车涂装线前处理除杂质系统

The removal of impurity system for Pretreatment in car coating line

前处理作为涂装的重要工序,直接决定着电泳涂装效果的好坏,前处理过程会产生大量的铁屑、胶体、油污和纤维等杂质,不仅影响脱脂液的质量,又污染环境。研究高效环保的新型除杂质工艺技术具有重大意义。论文就现有的前处理除杂质系统进行对比研究,对不同类型的前处理除杂质方式的应用进行探索。

Pretreatment is an important process for car coating,which directly decides the effect of coating.The pretreatment process can produce a large amount of iron filings,colloids,oil and fiber impurities,which not only affect the quality of degreasing fluid,but also pollute the environment.It is a great significance to study the high efficiency technology of environ-mental protection.In this paper,a comparative study is made on the existing pretreatment impurity system,and the application of different types of pretreatment and impurities is explored.
