研究氯磺化聚乙烯(CSM)的流变性能,特别是剪切速率、剪切应力和温度对CSM熔体表观粘度的影响。试验结果表明,CSM熔体在试验温度范围内为假塑性流体,随温度的升高其非牛顿性减弱;CSM熔体的表观粘度随表观剪切速率和剪切应力的增大以及温度的升高而降低;剪切应力对CSM的粘流活化能影响不大。
The rheological properties of chlorosulfonated polyethtylene (CSM),especially the effect of the shear rate,shear stress and temperature on the apparent viscosity of CSM melt,were investigated.The test results showed that the CSM melt was a pseudoplastic fluid and its non-Newtonian behaviour weakened as the temperature raised;the apparent viscosity of CSM melt decreased as the apparent shear rate and shear stress increased and the temperature raised;and the shear stress had little effect on the activating energy of CSM viscous flow.
