分析了电泳漆膜上形成气泡露底缺陷的原因。通过调整电泳槽中部分循环喷嘴方向，对作为阴极的车身下表面形成冲刷，可有效避免电解水产生的氢气聚集，改善气泡露底缺陷，提升漆膜质量。

The causes for holiday defect on electrophoretic coating were analyzed. The bottom surface of car body as cathode was scoured by adjusting the direction of some nozzles used for bath circulation at the tank bottom, which can effectively avoid hydrogen gathering produced by electrolysis of water. Thus the bubble-caused holiday defect is ameliorated and the coating quality is improved.
