摘要: 本实验通过浓度、剪切力、温度、pH、盐度、水化时间、冻融等变化对车前子胶溶液表观黏度的影响,对车前子胶溶液的流变性进行了研究。结果表明:车前子胶溶液为"非牛顿流体",具有"假塑性"。其表观黏度随质量分数的增加逐渐增加;体系温度升高可导致溶液黏度降低,溶液在pH5~11时较稳定;车前子胶对NaCl具有良好的兼容性,Ca2+对车前子胶溶液有显著的增稠效应,其增稠效果与离子浓度呈正相关。此外,车前子胶溶液有良好的抗降解性能,冻融变化使车前子胶溶液黏度有所升高。

Abstract: In this paper, the effects of concentration, shearing, temperature, pH, salt-concentration freazing-thawing on the viscosity of plantasan was studied. Results showed that plantasan was non-Newton fluid, and the solution had pseudoplasticity. Apparent viscosity increased with the increase of concentration; the increasing of temperature can reduce the viscosity of plantasan; the viscosity is not affected by the pH 5~11; it has better compatibility with NaCl, Ca2+ obviously improve its viscosity, and the ability is correlated to the concentration of Ca2+ ions. Plantasan had better stabilization of resisting degradation, its viscosity increased with the freezing-thawing.

Key words: plantasan, rheological property, apparent viscosity
