摘要
测定了聚丙烯腈 -硫氰酸钠水溶液在不同浓度下的流变性能 ,分别建立了剪切速率、温度、浓度与粘度的关系 ,进一步得到以剪切速率、温度、浓度为自变量的粘度关联式 ,将关联式应用于浓度的计算 ,计算值与实验值误差小于 2 %。
The rheological properties of acrylonitrile copolymer in NaSCN\|aqueous were measured at various concentration. The relationships between shear rate, temperature or concentration and viscosity were established. The viscosity was characterized as a function of shear rate, temperature and concentration. The equation was used to viscosity calculation, giving the calculating uncertainty below ±2% as compared with the experimental result.
