中文摘要: 采用ARES流变仪研究了从1g/L到40g/L不同浓度的黄原胶水溶液在303.15K-343.15K范围内的流变性能。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;浓度为2g/L时,粘度和温度关系满足Arrhenius定律,随着黄原胶浓度增大,温度对粘度的影响不再符合Arrhenius定律;黄原胶水溶液的线性粘弹区范围几乎与浓度无关,同一浓度的黄原胶水溶液弹性模量 G' 远大于粘性模量G",表明溶液中存在类凝胶结构。
Abstract:Rheological properties of different xanthan gum solutions with concentration of 1g/L to 40g/L have been investigated under 303.15K to 343.15K. The results showed that xanthan gum solution behaved like pseudo-plasticity 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 2g/L xanthan gum solution well. The concentration of xanthan gum solutions had little influence on linear viscoelastic range. Storage modulus G'was much higher than loss modulus G"for a given xanthan gum solution,which demonstrated gel-like structure in xanthan gum solutions.
