水玻璃再生砂中Na_2O残留量的分析方法

A Method for Analysing The Residual Na_2O Content in Recycled Sodium Silicate Bonded Sand

水玻璃系再生砂质量与其残留Na2O的数量有较大关系。经过对几种检测水玻璃类再生砂中残留Na2O方法的研究,阐明一种非常简便的方法———盐酸滴定法。实践证明,该方法检测结果稳定、容易掌握、检测耗时少、成本低。

There is very important relation between the soluble glass kind of reborn sand and the leftover Na 2O in it. By studied some kinds of ways to measure the leftover Na 2O in the soluble glass kind of reborn sand,elucidate a simple and convenient way——hydrochloric acid titration.It shows that:the detect result is steady and easy to grasp,and it costs a litlle time, gets Vile cost.
