【摘要】：针对在某次汽车水性银色漆的涂装中面漆出现"黑点"问题,分析涂装工艺、材料本身变质、外来污染源等因素,通过排查,并依据喷板试验及红外光谱分析,最终确定喉封液渗入水性银色漆导致了"黑点"问题的发生,通过维修输漆管路系统动力泵的密封性及更换罐体内污染的水性银色漆,解决了水性漆色漆的"黑点"问题。
[Abstract]:Aiming at the``black spot'' problem in the coating of the water-based silver paint of a certain automobile, the paper analyzes the painting process, the deterioration of the material itself, the external pollution source, etc. Through the troubleshooting, and according to the spray plate test and the infrared spectroscopy analysis, it is determined that the seepage of the laryngeal liquid into the water-based silver paint leads to the``black spot'' problem. The problem of``black spot'' problem is solved by repairing the maintenance of the power pump of the power pump of the paint conveying system and replacing the water-borne silver paint in the tank body.
