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。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.
