研究了石英粉耐火骨料的粒度分布对消失模铸造涂料的透气性和粘度的影响。为了得到性能优良的涂料 ,在配制涂料时应使用粒度集中的耐火骨料。
The effect of grain size distribution of refractory aggregate on the air permeability and viscosity of the lost foam casting coating was studied. In order to get excellent performance coatings, the preparation of coatings should be used when the particle size of the fire-resistant aggregate.
