摘　　要：针对酯硬化水玻璃砂的实际应用情况，采用正交试验分析了KOH、溃散剂、增强剂对型砂溃散性的影响。结果表明，KOH、溃散剂及增强剂中，溃散剂的加入量对酯硬化水玻璃砂溃散性的影响是最大的。最佳工艺条件为KOH加入量5％，溃散剂加入量6％，增强剂加入量0．1％。Based on the practical application of ester cured sodium silicate sand, the effects of KOH, break- down agent and strengthening agent on the collapsibility of molding sand were analyzed by orthogonal experiment. The results show that among KOH, break-down agent and strengthening agent, the addition of break-down agent is the biggest impact on the collapsibility of ester cured sodium silicate sand. The best process conditions is 5% for KOH, 6% for break-down agent and 0.1% for strengthening agent.
