通过对不同的初始含水量的水玻璃旧砂进行干法再生处理，经抽样化学分析检测再生效果，揭示了旧砂含水量与再生砂的NaO2残留量的关系。含水量小于0.1%干法再生效果很佳，含水量越大再生效果越差，含水量大于0.7%的水玻璃旧砂难以机械干法再生。

Reclaimed sodium silicate sand with diff erent of initial watercontent,sampled and detected effection of sand reclamatio n by chemistry test.Announced relation of water content of used sand with residu a l Na2O.The effection of reclamation is worse as water content is larger.When content of water bleow 0.1%,the effection is the best,and it is hard to reclaim as water content greater than 0.7%.
