【摘要】 采用旋转粘度计研究了HEC/CMC混合物水溶液的流变性质。结果表明 ,混合物体系中羧甲基纤维素 (CMC)含量高时 ,流动曲线符合幂律模型 ;羟乙基纤维素 (HEC)含量高时 ,则偏离幂律模型。同时还探讨了混合体系中溶液粘度的加和性以及温度依赖性更多还原

【Abstract】 The rheological behavior of aqueous solution of the HEC/CMC mixture were studied by rotatary viscometer.The results showed that the fluid-curve of the HEC/CMC solution followed Ostwed-Der Waele model at higher CMC content,but they didn’t follow the model at higher HEC contennt.Viscousity additive-property and thermostability of the mixed HEC/CMC solutions were also studied in this paper.更多还原
