1、对于涂层铝卷来说,所有的基板在生产过程中表面会残留一些油脂及润滑剂,当然在运输过程中还可能黏附着其他物质,如果不去除这些油脂及黏附物,会对铝板的涂装和使用造成影响.
1, for the coated aluminum coil, all the substrates will remain some grease and lubricants during the production process. Of course, during transportation, they may stick to other substances. If these oils and adhesions are not removed, the aluminum coating will be affected.
2、在清洁干净的基板表面需要经过化学处理以生成稳定的转化膜,从而提高基板的耐腐蚀性及对涂料的附着力.基板前处理技术是伴随涂层技术的生产而产生的,它是为涂层技术服务的,是为制备涂层打基础的.

In 2, clean up the surface of the substrate through chemical processing to generate stable conversion film, thereby improving the corrosion resistance and adhesion of coating substrate. Substrate pretreatment technology with coating technology production and produce, it is for the coating technical service, is for the preparation of excellent coating and lay the foundation.
3、对于彩涂铝板来说,它的涂装方式是一般彩涂铝板涂装工艺按涂料的涂装层数可分为三涂工艺、二涂工艺及单涂工艺三种.按涂布辊和传动辊的转动方向可分为顺涂和逆涂两种工艺.可以得到所需厚度、外观平整的涂膜.
3, for the color coated aluminum coating, it is usually painted aluminum coating process by coating layers of paint coating process can be divided into three and two coating process and coating process of single three. According to the direction of rotation of the applicator roll and roll can be divided into direct coating and reverse coating two kinds of coating process. Get the required thickness, smooth appearance.
