对具有络合作用及能使亚硝酸分解的化合物在硝酸——钢铁腐蚀体系中的缓蚀作用进行了探索。结果表明,最佳复配缓蚀剂在一般酸洗、除垢的条件下,缓蚀率在99.6％以上。
Corrosion inhibition of compounds with complexation and decomposition of nitrous acid in nitric acid-steel corrosion system was explored. The results showed that under the conditions of general pickling and descaling, the corrosion inhibition rate of the best compound corrosion inhibitor was over 99.6%.
