【摘要】 对水玻璃砂再生的质量控制进行了数理分析。结果认为,水玻璃砂采用螺旋振动再生,脱膜率是一定的,通过调整新砂加入量,即可使Na2O%的含量趋于并达到一个稳定的水平上,从而可以实现水玻璃干法再生砂的单一砂使用。更多还原

【Abstract】 Mathematical analysis for quality control of the reclamation of the used water glass sand has been described in this paper. The result shows that water glass sand shall be reclaimed by helical vibration with certain stripping rate. Through the adjusting of the amount of new sand, the content of Na 2O% trend to a stable level so as to realize water glass sand with the dry reclaimed method to be available.更多还原
