气相二氧化硅胶体电解液的胶凝时间测定方法

The methods for measuring the gelling time of fumed silica colloidal electrolyte solution

本文建立了测定气相二氧化硅胶体电解液胶凝时间的流变学方法,同时规范了目测方法。由这些方法可以较好地测定气相二氧化硅在硫酸介质中的胶凝时间,可为研制优良性能的铅酸蓄电池胶体电解液提供实验方法支持。

The rheological method measuring the gelling time of colloidal electrolyte generated by fumed silica has been established. Meanwhile the method guided by eye was standardized as well. By the methods, the gelling time of fumed silica in sulfuric acid solution can be well measured, which provides the support of experimental methods to the development of excellent gelled lead-acid battery.
