  钢结构重防腐工程最常用的三种富锌底漆,即水性醇溶无机富锌底漆,无机富锌底漆和亚博登录亚博登录首页APPAPP:环氧富锌底漆,锌含量接近的三种底漆,生产成本接近,市场卖价接近,基础性能也很接近,用来做重防腐涂料体系的底漆,三种富锌底漆都能满足要求。但是,三种富锌底漆各有特点,根据不同场合及用途,合理选用合适的底漆,是很有必要的。

  其次是醇溶无机富锌底漆,跟环氧富锌底漆比,其耐温性和可焊接性明显优于后者。其不足之处在于,对施工环境要求高,比如要求湿度高,便于漆膜完全固化,固化时间长,最少24h最长3天;配套性较差,如果醇溶无机富锌底漆漆膜没有完全固化,而后面喷涂环氧涂料,后续极有可能出质量问题,加上其VOC很高,未来的需求可能会进一步减弱。

  当然,亚博登录亚博登录首页APPAPP:水性无机富锌底漆做重防腐涂料体系的底漆,确实没有优势,在其他地方,还有很好的用武之地。比如,作为耐温400度的底漆,作为单一涂层使用,作为可焊接不用打掉的预涂底漆,作为各种中性溶剂储罐内壁防锈导静电底漆等等。
