摘要

应用极化曲线、表面张力、放电实验和SEM等测试方法,研究了阴离子表面活性剂十二烷基苯磺酸钠(简称SDBS)和非离子表面活性剂吐温-20(简称Tween)之复配体系(简称ST)在碱性介质中对锌电极电化学性能的影响及其作用机理.实验表明,复配缓蚀剂ST具有比单一添加SDBS或Tween更高的缓蚀效率,并且二者具有明显的协同作用,Tween在复配体系中的作用是使活性物质于锌电极表面的临界胶团浓度显著降低,吸附分布更加均匀.从而可更有效的抑制锌电极腐蚀,改善锌电极的表观形貌,达到延迟钝化的效果,使活性物质利用率得到显著提高.

Abstract

The synergetic influence of sodium dodecyl benzene sulfonate(SDBS) with Tween-20(Tween) on zinc electrode was studied by polarization experiment,surface tension test,discharge test and SEM.It is found that the composite inhibitor ST has a much higher efficiency.The addition of Tween reduced the critical micell concentration of SDBS on zinc electrode remarkably and the distribution of adsorption became more homogeneous.ST inhibits corrosion of zinc electrode and improves discharge capacity of the whole battery.Through electrochemical morphological observation of anodic passivation behaviors of zinc electrode,the absorption of ST on electrode surface makes discharged production much smaller and keeps crude porous structure intact.Passivation of zinc electrode has been postponed.
