涂装工艺分析可以消除或者降低车身结构缺陷引起的涂层质量问题。从排液性方面对影响车身涂装前处理及电泳质量的结构进行了分析,重点对四门两盖结构及车身底部总成结构中常见的积液问题进行了案例说明并提出相应优化措施。 Coating process analysis eliminates or reduces coating quality problems caused by body structure defects. From the liquid drainage aspect, it analyzes the structure that affects the pretreatment and electrophoresis quality of the bodywork, and emphatically illustrates the case of effusion which is common in the four-door two-cover structure and the bottom body assembly structure and puts forward the corresponding optimization measures.
