随着工农业生产的迅速发展,用户对汽车质量的要求越来越高,就涂装技术而言,无论对装饰性还是耐腐蚀性都提出了更高的要求。尤其是近几年出国车数量不断增加,要求更为严格。国产汽车在装饰性和耐腐蚀性等方面与先进国家相比还存在着一定差距,如加拿大标准规定,汽车使用一年半外表面不允许出现锈点,而我们的车子使用一年在驾驶室及车箱边板等部位己产生严重锈蚀,有的新车存放几个月就出现锈点。锈蚀都是从狭缝及中空零件的内表面开始,经常可以看到,从这些部位往外流锈水,并 With the rapid development of industrial and agricultural production, users are demanding higher and higher quality automotive products. As far as coating technology is concerned, higher demands are placed on both decorative and corrosion resistance. In particular, the number of overseas vehicles has been on the increase in recent years and demands are more stringent. Domestic cars in the decorative and corrosion resistance and other aspects compared with the advanced countries there are still some gaps, such as Canadian standards, the use of cars a year and a half outside the surface does not allow rust, and our car a year in the cab And the car side panels and other parts have serious corrosion, some new car rust rust appears a few months. Rust is from the inner surface of the slit and hollow parts, you can often see, from these parts out of rust flow and
