CN105780026A 一种渗铝钢管的酸洗钝化剂及酸洗钝化方法 无效 - 驳回

一种渗铝钢管的酸洗钝化剂及酸洗钝化方法
摘要：
本发明公开了一种渗铝钢管的酸洗钝化剂及酸洗钝化方法，由按质量百分数为5％～20％的硝酸、2％～10％的氢氟酸、5％～15％的盐酸、5％～15％的硫酸、0.5％～2％的缓蚀剂、0.5％～2％的添加剂、其余为水组成。本发明对渗铝钢管进行酸洗钝化的过程中不会产生酸雾，该酸洗钝化方法对渗铝钢管进行处理的操作工艺较为简单。
摘要（英）：

The invention discloses a pickling passivator and pickling passivation method for an aluminized steel pipe. The pickling passivator is composed of, by mass, 5%-20% of nitric acid, 2%-10% of hydrofluoric acid, 5%-15% of hydrochloric acid, 5%-15% of sulfuric acid, 0.5%-2% of corrosion inhibitors, 0.5%-2% of additives and the balance water. According to the pickling passivator and pickling passivation method for the aluminized steel pipe, acid mist does not occur in the pickling passivation process of the aluminized steel pipe, and the pickling passivation method for processing the aluminized steel pipe is simple in operation technology.
