摘要

采用结构流变模型描述了聚丙烯酰胺水解水溶液的流变行为。固定流动过程中粘度的变化可以用大分子间接触引起的聚合物溶液结构变化来解释。除高剪切速率区域出现剪切增厚现象外，广义流动方程可以很好地近似于流动曲线。流变方程系数随聚合物浓度变化的行为与结构流变模型的结论一致。

Non-Newtonian Flow of Hydrolyzed Polyacrylamide Solution

Structural rheological model is used to describe the rheological behavior of hydrolyzed polyacrylamide aqueous solutions. The change in viscosity during stationary flow is explained by structure change of the polymer solution associated with contacts between macromolecules. Flow curves are well approximated by the generalized flow equation, except for the region of high shear rates, where the phenomenon of shear thickening is observed. The behavior of the rheological equation coefficients with a change in the polymer concentration is consistent with the conclusions of the structural rheological model.
