摘　　要：研究了1种硅酸盐无机粘结剂树脂砂的强度和发气特性,通过对比试验确定了粘结剂加入的最佳比例。结果表明,发气特性曲线显示该树脂砂的发气量很低,发气速度较慢,粘结剂的加入量对发气量、发气速度影响很小。用该粘结剂制作大长径比的油路型芯,可以消除油路呛气缺陷。The strength and gas-evolution characteristics of a kind of silicate inorganic binder resin sand were studied,and the optimum proportion of binder was determined by contrast test.The results show that the gas-evolution characteristic curve of the resin sand is very low and the gas emission velocity is slow,and the amount of binder has little effect on the gas-evolution and gas-evolution velocity.The gas defects in long and small oil channel can be eliminated by the core made by this silicon inorganic resin sand can be eliminated.
