摘　　要：利用腐蚀实验，比较了几种缓蚀剂对锌在铵型及锌型电解质溶液中的缓蚀效果，从析氢速度看，文中所选的Ⅰ号季铵盐型缓蚀剂对抑制锌上氢的析出效果最佳。又用测量锌电极的阴、阳极极化曲线的方法研究了缓蚀剂Ⅰ的用量范围，并涂布成无汞浆层纸，做成Ｒ６Ｐ和Ｒ６Ｃ型电池。按照国标ＧＢ７１１２－８６对电池进行考查，结果证明，无汞电池的新电及储存之后的各项性能指标均达到和有汞电池相当的水平，并远远超过国家规定的标准。本文所用缓蚀剂的价格略低于汞，使用该缓蚀剂取代汞时，浆层纸的涂布工艺或电池的生产路线都不需作任何改动，电池的生产成本下降。因此，该技术十分易于在电池生产中推广应用。Abstract The effect of various Hg free additives on the corrosion of Zn in NH 4Cl based and ZnCl 2 based electrolytes has been compared by the corrosion experiments. It is shown that the quaternary ammonium salt type additive (designated as I #) is the best one to inhibit the hydrogen evolution on Zn. The quantity range of inhibitor I # is investigated with the cathodic and anodic polarization curves measurements. The R6P and R6C type cells with inhibitor I # have been tested. The results show that the performances of the Hg free cells are as good as those with Hg, meeting and beyond the specification of national standard GB 7112 86. The inhibitor I # has a little lower cost than HgCl 2, so it is beneficial to disseminate this new inhibitor in battery industry.
