摘要
本文研究了型砂促硬剂如乙二醇二乙酯、甘油二乙脂及棉油混合单双甘酯的制备工艺条件，并测定了它们促硬水玻璃溶液的速度和温度条件对促硬速度的影响。
The technical conditions of preparing several hardeny agents used for foundry moulding sand are studied in this paper, The velocity of their hardening Na2SiO3 solution was determined and the effect of temperature on the hardening velocity is also studied in the report
