摘要
以阳离子型聚丙烯酰胺水溶液为实验对象,研究了质量浓度、剪切速率、温度对聚丙烯酰胺溶液流变特性的影响。结果表明：PAM水溶液在质量浓度为0.5-2.0g/L时,其表观黏度呈现线性增长,随着质量浓度升高而增加;表观黏度随着剪切速率的增大而减小;随温度的增加而降低。流动特性指数n和稠度系数K随温度、质量浓度的变化符合幂律流体特性。综合温度、质量浓度的影响,拟合出表观黏度关于质量浓度、温度的关联式。
With cationic polyacrylamide aqueous solutions being an experimental obj ect,the experiment studied the effects of mass concentration,shear rate and temperature on the rheological properties of polyacrylamide aqueous solution.Experimental results indicate that the apparent viscosity of PAM solution increases linearly with increasing concentration at concentrations of 0.5-2.0g/L;the apparent viscosity decreases with the increasing of shear rate and temperature. With the changing of temperature and concentration,the flow behavior index n and consistency coefficient K behave similar to power-law fluid. Considering the combined effects of temperature and concentration, the experiment fitted an equation of the apparent viscosity with the regard to concentration and temperature.
