摘要
通过对几种膨润土的分析 ,测定型砂的发气特性及膨润土热失重 ( TG) ,讨论了膨润土的特性对型砂发气量和发气速度的影响 ,其结论对生产实际有着直接指导意义。
The effect of bentonite properties on gas evolution of molding sand is discussed by means of analysis of several kinds bentonite and testing gas evolution of molding sand and TG curves of bentonite. The results will have practical significance in production.
