| 摘 要： | 目的研究CP-CI021海水介质预膜缓蚀剂的缓蚀行为及复配工艺。方法主要采用失重法和电化学阻抗谱(EIS)研究CP-CI021对Q235碳钢在海水介质中的缓蚀行为,并优化出预膜缓蚀剂最佳复配工艺。结果 CP-CI021预膜缓蚀剂具有优异的缓蚀性能,经预膜处理的Q235碳钢测试的EIS阻抗模值增大了2个数量级。结论得到了预膜缓蚀剂的最佳复配工艺,有机膦PHA质量浓度为7.3 g/L,助剂A质量浓度为3 g/L,助剂B质量浓度为5 g/L,缓蚀效率高达98.4%。

| Abstract: | Objective To study the inhibition behavior and the optimal composition of CP-CI021 pre-filmed inhibitor for Q235 steel in seawater. Methods The inhibition behavior of CP-CI021 for Q235 steel in seawater and the optimal composition were investigated with weight loss method and electrochemical impedance spectroscopy. Results The CP-CI021 pre-filmed inhibitor had excellent inhibition property, and the EIS impedance modulus of pre-filmed Q235 steel increased by 2 orders of magnitude compared to the Q235 steel without pre-filming. Conclusion The optimal composition of CP-CI021 pre-filmed inhibitor was: PHA, 7.3 g/L, assistant A, 3 g/L, assistant B, 5 g/L, and the inhibition efficiency reached 98.4%. |
