摘 要:利用電化學測試技術研究了乙醇胺(ETA)、四正丁基溴化胺(TBA)和氯化十六烷基吡啶(CPC)三種陽離子型阻銹劑在不同NaCl濃度的混凝土模擬孔溶液中對鋼筋的防腐蝕性能的影響。研究結果表明:在低濃度的NaCl模擬體系中,阻銹劑對鋼筋的腐蝕防護效果較好;結合動電位極化測試和交流阻抗譜測試結果得出,CPC阻銹劑屬于混合型阻銹劑,通過在鋼筋表面吸附成膜抑制腐蝕過程,CPC對鋼筋的防腐蝕效果更佳。
Abstract: In the present work, the performance of several cationic corrosion inhibitors were studied by the electrochemical techniques in simulated corrosion solution containing different concentrations of NaCl. Results show that the inhibitors demonstrate obvious efficiency in the low concentration NaCl solution. Combined with potentiodynamic polarization test and electrochemical impedance spectroscopy, the chlorine pyridine (CPC) show good performance in corrosion protection. CPC is a mixed type inhibitor, which can restrain corrosion process by the quick adsorption of active component on steel surface.
