摘　　要：分析了不同粉末装载量下,喂料内黏结剂和粉末分布情况,估算出临界粉末装载量值;通过对同一配方黏结剂,不同粉末装载量的喂料,以及在转矩流变仪中混料过程的研究及毛细管流变仪中表观黏度的测定,得出最佳粉末装载量的试验值。试验结果表明,最佳粉末装载量试验值比估算值小约2%,本文中的方法可以作为最佳粉末装载量的简易测定方法。This paper analyzed the binder and powder distribution within the feedstock of the different powder loadage, and estimated the value of the critical powder loadage. The mixing process of feedstock based on the same recipe of binder but different powder loading was studied through torque rheometer and apparent viscosity was measured by capillary rheom eter, the experimental values of optimal powder loading were gained. The results showed that experimental values were a- bout 2% smaller than the estimated values, the method in this paper can be used as a simple method for optimal powder loading.
