为解决电泳固化不良引发粗糙度高，影响车身外观品质的问题，本文通过下调现场电泳槽液颜基比、提高溶剂丙二醇苯醚（PPH）含量、降低烘干炉升温速率和导入新型溶剂的措施，对电泳粗糙度进行改善探讨。结果表明：调整颜基比、溶剂含量、升温速率均无法有效改善粗糙度；添加某新型溶剂至电泳槽，能将电泳粗糙度降低至0.26~0.28 μm。研究表明：导入新型溶剂的措施彻底解决了电泳粗糙度的问题，同时车身外观也提升为光泽高、橘皮低的高品质水准，并且没有产生其他风险。
In order to ensure the high appearance quality of car body by solving the problem of the high electrophoresis roughness caused by inadequate resolution of electrophoretic curing，several measures are applied，such as the reduction of pigment/binder ratio，increase of the propylene glycol phenyl ether（PPH）content，decrease of the heating rate and addition of novel solvent. The results showed that the roughness can’t be effectively solved by adjusting the pigment/binder ratio，the solvent content and the heating rate. However，the addition of the novel solvent can completely solve the roughness which was reduced to 0.26~0.28 μm. The high electrophoresis roughness problem was solved by adding the novel solvent. Meanwhile，the appearance of the car body was improved to a high quality level which means high gloss and low peeling. There was also no additional risks.
