消除汽车车身中涂层颗粒缺陷的若干方法

摘要

总结了工作人员、升降台升降速率、输送管路、中涂烘干炉、中涂漆内高沸点溶剂、电泳涂层研磨工具、台车等因素对中涂层颗粒缺陷的影响.明确了导致颗粒缺陷的主要原因是烘干炉出现焊缝缝隙以及台车被污染.给出了相应的解决措施,有效地降低了颗粒缺陷的发生.%The effects of worker,lifting speed of lifting platform,delivery line,midcoat furnace,high-boiling-point solvent in midcoat,grinding tool for electrophoretic coating and skid conveyor on particle defects in midcoat of car body were summarized.The causes for particle defects mainly includes cracking on weld seam of the furnace and contamination of skid conveyor.Some countermeasures were given,effectively reducing the appearance of particle defects.
