摘要：采用ARES流变仪研究了质量浓度为1.0-40.0 g/L的黄原胶水溶液在303.15-343.15 K的流变性能。结果表明：黄原胶水溶液为假塑性流体,幂律模型能很好地关联其流变方程;当质量浓度为2.0 g/L时,黏度和温度关系满足Arrhenius定律,随着黄原胶质量浓度增大,温度对黏度的影响不再符合Arrhenius定律;黄原胶水溶液的线性黏弹区范围几乎与质量浓度无关;同一质量浓度的黄原胶水溶液弹性模量G′远大于黏性模量G″,表明溶液中存在类凝胶结构。
Rheological properties of xanthan gum solutions with concentration range of 1.0 g/L to（40.0） g/L are investigated under 303.15 K to 343.15 K.The results showed that xanthan gum solution behaved like pseudoplastic fluid and the relationship between its viscosity and shear rate could be described by the power-law model.The Arrhenius equation could only fit the viscosity and temperature data of 2.0 g/L xanthan gum solution well.The concentration of xanthan gum solutions had little influence on their linear viscoelastic range.Storage modulus G′ was much higher than loss modulus G″ for a given xanthan gum solution,which demonstrated the existence of gel-like structure in xanthan gum solutions.
