钢材表面的预处理:

油脂     •可用溶剂(如脂肪烃或松香水等)凊除油脂。但要除去含油脂的溶剂又是一个难题, 用布抹干必须两至三次方才有效,每次都需要用干净的抹布,只抹一次是不够的,而且可能使油污面积更加扩大,情况更糟。可用化学清洗剂来凊除油渍,但一定要确定其对涂层表面无侵蚀作用,通常先将足够的凊洗剂涂在污物上,等它渗入几分钟,然后用清水彻底冲洗,油漆施工前必须凊除所有清洗剂的残迹。

 

盐类     •应以凊水洗净,以压缩空气吹干。

涂车间底漆   •对预处理的钢材在除锈质量达到要求后,必须立即涂装一道车间底漆,以防在储存、装配涂装过程中钢板生锈,并为涂装后道防锈漆保护好钢板的表面。
 

直接涂装电竞竞猜app哪个好   •釆用分段喷丸或喷砂除锈时,在整个分段的除锈质量达到要求后,可直接涂装第一道防锈漆,而不需要涂装车间底漆。

 

二次除锈     •涂有车间底漆的钢板表面处理
