摘要:采用旋转法测定吐温80纯液体及其水溶液在不同温度下的动力粘度,试验结果表明:吐温80纯液体的动力粘度随温度升高而下降,当温度达到45℃以上时,下降趋缓;少量柠檬酸钠等无机电解质对吐温80水溶液的粘温行为没有明显影响;少量极性有机物无水乙醇使吐温80水溶液的动力粘度相应地下降;吐温80与吐温20纯液体混合后,体系的粘温行为介于2种纯液体之间.

关键词: 吐温80, 粘度, 温度, 旋转法

Abstract: The dynamic viscosity of pure liquid and its aqueous solution of Tween 80 was  measured by rotational method.The result of test shows that the dynamic
 viscosity of pure Tween 80 drops with temperature up,and drops slowly as temperature comes at 45 ℃.Morsel inorganic electrolyte such as sodium citric acid doesn't have an apparent effect on the behaviour of viscosity and temperature of Tween 80 aqueous,and morsel polarity organic substance hold the dynamic viscosity of aqueous solution of Tween 80 to drop.The behaviour of viscosity and temperature of mixed system by Tween 80 and Tween 20 is between them.

Key words: Tween 80, viscosity, temperature, rotational method
