高吸水树脂的溶胀动力学

Swelling Kinetics of Super-Absorbent Polymer

摘要: 基于扩散-松弛模型,分别研究了树脂粒度和溶液浓度对高吸水树脂溶胀行为的影响。实验结果表明:水分子的扩散和树脂大分子链段的松弛对树脂的溶胀均有贡献,但两者贡献大小与树脂粒度和溶液浓度有关。

Abstract: Based on a diffusion-relaxation model,the influence of particle size and solution concentration on super-absorbent polymer(SAP) swelling kinetics is studied in this paper.The diffusion of water molecule and the relaxation of the chains of the polymer both
