表面漂浮阳极的应用及推广

Application and Promotion of Floating Anode

在Ro-Dip(全旋反向浸渍输送系统)电泳涂装过程中,门槛由于位于槽体的上部且会受到四门的遮挡作用,使漆膜的上电受到一定程度的影响,导致门槛部位膜厚较其他部位偏薄。针对这种特殊位置,增加表面漂浮阳极,可以在保证其他部位膜厚不变或降低的情况下提高局部车身膜厚,并降低车身的电泳单耗。对表面漂浮阳极的试制及其在使用过程中遇到的一些问题及解决方案进行了介绍。

During Ro-Dip electrophoresis coating process, the threshold was at the top of the tank and obscured by four doors which affected the power-on of the paint film to a certain extent. GeneraUy the thickness of threshold area was thinner than that of other area. Addition of floating anode at special position could increase local thickness and reduce unit consumption of electrophoresis, at the same time, ensured that the film thickness of other parts was constant or reduced. The difficulties and solutions in development and application of the floating anode were introduced.
