摘要
通过傅立叶红外光谱、旋转挂片法、极化曲线法、交流阻抗法研究了醇胺开环改性聚天冬氨酸的缓蚀性能及缓蚀机理。研究表明,乙醇胺、二乙醇胺、三乙醇胺开环改性PASP中以加入乙醇胺所得改性产物的缓蚀性能最好,缓蚀率达到70.18%。醇胺改性的PASP是一种以抑制阳极为主的缓蚀剂。
The corrosion inhibition capacity and mechanisms of alcoholamime modified PASP has been studied by using FT-IR, methods of rotary coupon,Tafel polarization curves, and AC impedance. The results show that PASP modified by ethanolamine has the best performance, and the corrosion inhibition rate amounts to 70.18%. Alcohola- mime modified PASP is a kind of corrosion inhibitor that inhibits anode mainly.
