1、對于涂層鋁卷來(lái)說(shuō),所有的基板在生產(chǎn)過(guò)程中表面會(huì )殘留一些油脂及潤滑劑,當然在運輸過(guò)程中還可能黏附著(zhù)其他物質(zhì),如果不去除這些油脂及黏附物,會(huì )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(jīng)過(guò)化學(xué)處理以生成穩定的轉化膜,從而提高基板的耐腐蝕性及對涂料的附著(zhù)力.基板前處理技術(shù)是伴隨涂層技術(shù)的生產(chǎn)而產(chǎn)生的,它是為涂層技術(shù)服務(wù)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(lái)說(shuō),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(dòng)輥的轉動(dòng)方向可分為順涂和逆涂?jì)煞N工藝.可以得到所需厚度、外觀(guān)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.
