保水剂是近年来国内外研究合成的一种新型高分子材料。与水接触时能迅速吸收等于自身重量数百倍乃至上千倍的水,成透明凝胶状,而不溶于水和有机溶剂。吸收的水分能保持相当长时间,缓慢释放,失水后成膜或颗粒状。这种吸收—释放水的性能可以重复
Water-retaining agent is a new type of polymer synthesized at home and abroad in recent years. When in contact with water can quickly absorb equal to hundreds of times its own weight or even thousands of times the water into a transparent gel, but not soluble in water and organic solvents. Absorbed moisture can be maintained for a long time, slow release, dehydration after the film or granular. This absorption-release of water can be repeated
