- 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.
