摘要
介绍了酯固化水玻璃自硬砂旧砂砂粒表面水玻璃膜的主要化学成分,分析了水玻璃再生砂中Na2O含量的测定(参考方法)[1]产生误差的原因,推荐采用Q/HYT/-51-2012[2]法测定水玻璃再生砂中Na2O含量。
The surface chemical components of used sodium silicate sand were presented.The errer of the measurement（reference method）of Na2O in used sodium silicate sand was analyzed.Q/HYT.51-2007 method for the measurement of Na2O in used sodium silicate sand was recommended.
