主要对比了磷酸锌与磷酸钛表调对车身电泳底漆的影响。磷酸锌表调能细化磷化晶粒,减少成膜时间,对磷化槽液温度要求低,且寿命长、耐污染。这不仅能提升车身质量和磷化膜性能,还能节省成本。因此,磷酸锌表调在汽车涂装中有广泛应用前景。

This article compares the impact of zinc phosphate and titanium phosphate surface conditioning on the E-coat of car bodies.Zinc phosphate surface conditioning can refine phosphating grains,reduce the film-forming time,have lower requirements for phosphating bath temperature,and have a longer lifespan and better resistance to pollution.This not only improves the quality of the car body and the performance of the phosphating film,but also saves production costs.Therefore,zinc phosphate surface conditioning has broad application prospects in automotive painting.
