高吸水树脂是一种新型功能高分子聚合物，可以作为吸水剂、增稠剂、脱水剂、缓释剂、保鲜剂等使用。他是一种能迅速吸收自身重量几百倍甚至上千倍的水分而变成凝胶状，一般压力难于将水排除的高分子交联物质。本文简单介绍了超强吸水剂的合成，重点介绍了在大田应用效应。实验证明ＰＰＡＣ－超强吸水剂是农业开发上一个很好的材料，具有明显的经济效益和社会效益，应用于不同农作物上可增产１５－２５％，效果明显。
High water-absorbing resin is a new type of functional polymer, which can be used as water-absorbing agent, thickener, dehydrating agent, release agent and preservative. He is a polymer that quickly absorbs hundreds of times or even thousands of times its own weight into a gel and is generally hard pressed to remove water. This article briefly introduces the synthesis of superabsorbent, highlighting the application effects in the field. Experiments show that PPAC-super absorbent is a good agricultural development material, with significant economic and social benefits, applied to different crops can increase 15-25%, the effect is obvious.
