附着力是影响涂膜外观和性能的关键指标。针对生产现场发现的一次面漆涂膜脱落问题,对缺陷产生原因进行了多层次分析。通过减少冲压件表面油量和优化后门内板供件料架的方式彻底解决了该问题,同时以该问题的解决过程为例探讨了生产现场问题的解决思路。

The adhesion force is a key indicator affecting the appearance and performance of coating film.In view of the film peeling off found at the production site,the causes of defects were analyzed at multiple levels.This problem was completely solved by reducing the surface oil of the stamping parts and optimizing the feed frame of rear door inner plate.At the same time,the solution of this problem was taken as an example to discuss the on-site problem-solving process.
