分析了电泳二次流痕缺陷形成的原因,通过调整优化车身折边胶位置及涂胶直径等一系列措施,有效减少了包边间隙,避免了涂装后包边缝隙积液,改善了包边电泳二次流痕缺陷,提升了漆膜的耐腐蚀性能.

The root causes of electrophoresis secondary flow marks in bending for car’s door are analyzed. A series of measures, such as adjusting and optimizing the position and the diameter of the coating, can effectively reduce the gap in the bending, avoid the effusion of the gap after coating, improve the defect of the secondary flow marsk, and improve the corrosion resistance of the paint film.
