利用Instron3211型毛细管流变仪和Instron3325型流变力学谱仪研究了棉纤维素/N-甲基吗啉-N-氧化物一水合物(NMMO·H_2O)溶液流变性能,讨论了剪切速率、温度和溶液中的纤维素的质量分数对棉纤维素/NMMO·H_2O溶液流变性能的影响,计算了不同质量分数溶液的粘流活化能。
The rheological properties of cotton cellulose / N-methylmorpholine-N-oxide monohydrate (NMMO · H 2 O) solution were investigated by using Instron3211 capillary rheometer and Instron3325 rheological mechanical spectrometer. The effects of shear rate , Temperature and the mass fraction of cellulose in the solution on the rheological properties of the cotton cellulose / NMMO · H_2O solution were calculated. The viscous flow activation energies of different mass fractions were calculated.
