剪切速率对表面活性剂/水体系的作用研究

A Study about the Effect of Shear Stress on Surfactants/H_2O

本文研究了剪切速率对表面活性剂/水体系粘度的影响.结果表明在低剪切速率下,该体系的粘度随其浓度和温度的变化有两个特征;在粘度突跃区,该体系呈现假塑性流体,遵循时温等效定律:在非粘度突跃区,该体系是现出牛顿流体的特点,此时温度成为粘度的主要影响因素.

The effect of the shear stress on the viscosity of the surfactant/H2O is studied in this paper. The results state that under the low shear rate,two characters,which are the viscosity-jump area and the viscosity-unjump area, lie in the relation between the concentration as well as the temperature and the viscosity of the surfactants/H2O mixture. In the viscosity -jump area,this system becomes a pseudoplastic fluid and obeys the law of time equivalent to temperature. In the viscosity- unjump area,the system becomes Newdonal fluid and the temperature becomes the main effect on the viscosity
