在酸浸脱除金属表面氧化皮过程中,不可避免要产生酸对金属基体的腐蚀,这不但造成钢材的无谓损失,也造成酸液的大量浪费。据资料报道,酸浸时不加缓蚀剂比添加缓蚀剂酸的浪费竞相差20倍之多。为了尽可能的减小钢材的损失和酸的浪费,一般酸浸过程中均使用缓蚀剂。酸浸开始用硫酸,六十年代改用盐酸。其采用的缓蚀齐品种也有多种牌号。例如硫酸介质中有苏联的КИ-1,日本的IBIT-600L,美国的Rodine-95、Rodine-107等。盐酸介质中有日本的IBIT-710N,美国的Rodine-50、Rodine-1150,西德的
Acid leaching of metal surface oxide scale in the process, inevitably have to produce acid corrosion of the metal matrix, which not only causes deadweight loss of steel, but also caused a lot of waste of acid. According to the information reported, when acid leaching without corrosion inhibitor than adding corrosion inhibitor acid wasted 20 times less. In order to minimize the loss of steel and acid waste, corrosion inhibitors are generally used in the acid leaching process. Acid leaching began with sulfuric acid, hydrochloric acid into the sixties. The corrosion inhibitor varieties also have a variety of grades. For example, sulfuric acid medium in the Soviet Union КИ-1, Japan’s IBIT-600L, the United States Rodine-95, Rodine-107 and so on. There are hydrochloric acid medium in Japan IBIT-710N, the United States Rodine-50, Rodine -1150, West Germany
