针对硅烷电泳涂装线复产调试期间车身出现明显的电泳漆膜针孔问题进行研究。通过实验室模拟及随线挂板验证的方式,对板材、前处理槽液、电泳槽液、设备等排查,最终确定漆膜针孔问题在电泳工序产生。通过对电泳工序槽液温度、溶剂含量、施工电压、软起时间等参数调整,漆膜针孔问题得到有效控制,确保了涂装线复工复产的顺利达成。

This article focuses on the obvious problem of pinholes in the electrophoretic paint film on the vehicle body during the resumption and debugging of the silane electrophoretic coating line.Through laboratory simulation and verification by hanging boards along the line,we investigated the board,pre-treatment tank solution,electrophoresis tank solution,equipment,etc.,and ultimately determined that the problem of paint film pinholes occurred in the electrophoresis process.By adjusting parameters such as the bath temperature,solvent content,construction voltage,and soft start time in the electrophoresis process,the problem of paint film pinholes has been effectively controlled,ensuring the smooth resumption of work and production on the painting line.
