研究了含氮杂环天然高分子改性水处理剂ＦＮＰ—Ｃ在１－０ ｍｏｌ／Ｌ 盐酸溶液中对Ａ３ 钢的缓蚀性能。评价了投加量、温度等对缓蚀性能的影响，比较了ＦＮＰ—Ｃ、ＥＤＴＭＰ、ＣＧ—Ａ 的缓蚀能力，考察了ＦＮＰ—Ｃ与ＥＤＴＭＰ的协同缓蚀作用，探讨了ＦＮＰ—Ｃ的缓蚀机理。研究结果表明，ＦＮＰ—Ｃ在中低温、低浓度盐酸介质中对Ａ３ 钢具有良好的缓蚀作用，是一种以抑制阴极反应为主的混合型缓蚀剂。
The corrosion inhibition of A3 steel with nitrogen-containing heterocyclic natural polymer modified water treatment agent FNP-C in 1-0 mol / L hydrochloric acid solution was studied. The corrosion inhibition capacity of FNP-C, EDTMP and CG-A were evaluated. The synergistic corrosion inhibition effect of FNP-C and EDTMP was investigated. The effects of FNP-C Corrosion inhibition mechanism. The results show that FNP-C has a good corrosion inhibition effect on A3 steel in medium and low temperature and low concentration hydrochloric acid medium, and is a mixed type corrosion inhibitor that mainly suppresses cathode reaction.
