| 摘 要： | 研究了碱性电解液添加剂二乙醇胺[(C2H4OH)2NH]、三乙醇胺[(C2H4OH)3N]及两者混合对锌电极的影响。二乙醇胺单独使用可显著推迟锌电极的钝化,但对腐蚀略有加速,并会使电极的可逆性下降;三乙醇胺单独使用可推迟钝化并提高可逆性,但效果不明显,且对腐蚀略有加速。当两者以适当比例混合时,不但提高了电极的可逆性,而且几乎可以完全抑制钝化,虽然对腐蚀略有加速,但影响不大。当在电解液中加入0.3%二乙醇胺+0.1%三乙醇胺时效果最好。

| Abstract: | The influences of adding diethanolamine[(C2H4OH)2NH],triethanolamine[(C2H4OH)3N] and their mixture into alkaline electrolyte to the zinc electrode were studied.Diethanolamine could obviously delay the passivation performance of zinc electrode,but would accelerate corrosion and decrease the reversibility of electrode.Triethanolamine could delay the passivation performance and the reversibility,but the effect was not obvious.The proper mixing of diethanolamine and triethanolamine could improve the reversibili... |
