淀粉基多孔高吸水树脂致孔剂对吸液速率影响（Effect of Porosity Generators on Absorbency Rate Starch-based Superabsorbent）
高吸水树脂 致孔剂 吸液速率
2009/11/3
研究了淀粉基多孔高吸水树脂的合成及其吸液性质，比较了不同致孔剂如丙酮、碳酸氢钠、蔗糖对树脂吸液速率的影响。结果表明，添加致孔剂能有效提高树脂的吸液速率，碳酸氢钠具有较好的致孔效果。扫描电镜分析证明，合成的高吸水树脂具有疏松的多孔结构，它是提高高吸水树脂吸液速率的主要原因。
Using of geocomposite with superabsorbent synthetic polymers as water retention element in vegetative layers
geocomposite superabsorbent anti-erosion protection water retention
