摘要
在陶瓷粉末注射成型中,用不同比表面积的氧化铝粉分别以50%,55%,60%和65%的装载量制成不同的喂料,通过测出各喂料的粘度,讨论了粉末的比表面积、喂料装载量和剪切应力对喂料流动性的影响.喂料的粘度随剪切应力的增大而下降;随装载量的提高而增大;随着粉体比表面积的减小而减小.
The viscosity of feedstock is influenced by various factors in ceramic injection molding. In this paper different feedstocks by different loading capacity of 50% ,55% and 60% are made from a variaty of specific surface area of alumina powders. By measurement of viscosity of feedstock, much attentions are paid to the effects of specific surface area of powder, loading capacity and shearing stress on the fluidity of feedstock. The viscosity will decrease with the increase of shearing stress, increase with the enlargement of loading capacity, and decrease with the reduce of specific surface area.
