Troubleshooting Methods for Electrophoretic Pinhole Problems During the Resumption of Coating Line Production
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.
