摘要
介绍了改性水玻璃在有机酯自硬砂中的应用，生产实践证明，有机酯自硬砂中改性水玻璃相比普通水玻璃来说，具有加入量低，强度高，溃散性好，有利于旧砂的再生回用等优点。
The use of modified waterglass in ester-hardened sodium silicate sand is introduced. Production experience has showed that the modified waterglass has the advantage of lower additional amount, higher strength,, improved collapsibility and better reclamability.
