汽车车身由很多块薄钢板经冲压成形再拼焊而成。钢板表面的油污、铁锈,若不在漆前处理干净,就会造成漆层脱落,既影响车身外观又降低耐蚀性。车身漆前处理的方式有喷射式、半喷半浸式和全浸式三种。从1983年开始,我厂采用喷射或综合漆前处理工艺,获得了良好的效果。该工艺的设备投资少,占地面积少,处理成本低,生产效率高,是提高漆层附着力和车身耐蚀性的好方法。 Car body by a lot of thin steel sheet by stamping and then welded together. Steel surface oil, rust, if not clean before the paint, paint layer will fall off, both affect the appearance of the body and reduce corrosion resistance. Body paint pre-treatment methods are jet, half-jet half-immersed and all-immersed three. Since 1983, our factory has adopted the spray or integrated paint pre-treatment process, and achieved good results. The process of equipment investment, small footprint, low processing costs, high production efficiency, paint adhesion and body corrosion is a good way to improve.
