摘　　要：测定了不同分散相浓度及不同剪切速率条件下蒙脱石粘土 /水分散体系的表观粘度 ,采用将分散相浓度外推到零的方法求得分散体系的极限粘度 ,建立了体系极限粘度与分散相浓度之间关系 。A series apparent viscosity of montomorillite / water suspensions was measured at different shear rate under different montomorillite concentrations. The infinite viscosities of these suspensions, viscosities at infinite shear rate, were obtained by extrapolating montomorillite concentration to zero. Based on the experiment results, a viscosity equation for the suspension of montomorillite / water system was developed, and influence factors on the equation are disussed in this paper.
