摘要
含铝量55%的铝锌合金镀层很难采用常规的铬酸钝化液钝化,为给覆以这种镀层的钢板(带)提供再保护膜,本文提供一种新型的铬酸钝化工艺,其溶液中含有一种具有润湿、活化、氧化、封孔等综合效果的表面处理剂,能在这种铝锌合金表面形成致密的保护膜.
It is difficult to carryout conventional chromate treatment on the surface of steel plated with an Al-Zn alloy coating containing 55% A1. A novel chromating solution containing an additive which acts as a comprehensive agent in wetting, activating, oxidizing and sealing the surface has been found effective in forming a dense chromate film for the protection of such surfaces.
