1、對于涂層鋁卷來說,所有的基板在生產過程中表面會殘留一些油脂及潤滑劑,當然在運輸過程中還可能黏附著其他物質,如果不去除這些油脂及黏附物,會對鋁板的涂裝和使用造成影響.
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、在清潔干凈的基板表面需要經過化學處理以生成穩(wěn)定的轉化膜,從而提高基板的耐腐蝕性及對涂料的附著力.基板前處理技術是伴隨涂層技術的生產而產生的,它是為涂層技術服務的,是為制備涂層打基礎的.

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、對于彩涂鋁板來說,它的涂裝方式是一般彩涂鋁板涂裝工藝按涂料的涂裝層數可分為三涂工藝、二涂工藝及單涂工藝三種.按涂布輥和傳動輥的轉動方向可分為順涂和逆涂兩種工藝.可以得到所需厚度、外觀平整的涂膜.
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.
