表面活性剂对十六烷基羟乙基纤维素溶液黏度的影响

Effects of surfactant on viscosity of cetyl hydroxyethylcellulose solution

通过流变仪研究了几种表面活性剂对十六烷基羟乙基纤维素(CHEC)溶液黏度的影响。结果表明,CHEC溶液的黏度随表面活性剂质量分数的增加先升高,达到最大值后逐渐下降;温度对表面活性剂和CHEC混合溶液黏度的影响与表面活性剂和CHEC形成的复合物有关;表面活性剂与CHEC的疏水缔合作用强弱顺序是AES>6501>CAB。

Effects of surfactant on viscosity of cetyl hydroxyethylcellulose （CHEC） solution were investigated by rheometer. Experimental results indicated that the viscosity of CHEC solution increases with increasing of the surfactant concentration, and after a maximum value, then decreases with further addition of the surfactant. The effect of temperature on the viscosity of surfactant and CHEC solution depends upon the formation of surfactant/CHEC complex. The effect of variety of surfactant on the hydrophobic associate interaction of surfactant and CHEC is in the order of AES 〉 6501 〉 CAB.
