As a general polymer compound, sodium polyacrylate has a wide range of uses. It includes industrial-grade products used in industrial water treatment and food-grade products used as food thickeners. In addition, it can also be processed into water-absorbing materials.
What we need to explain is that the water-absorbing material must first meet the water-insoluble characteristics. The commercially available sodium polyacrylate dry powder type is a water-soluble product. That is, the sodium polyacrylate dry powder is added to the water, and after an appropriate stirring time, the liquid is viscous. Super absorbent polymer is a new type of polymer material that can absorb hundreds of times its own weight of water, non-toxic, harmless, and pollution-free.
Therefore, not all sodium polyacrylate products are super absorbent polymers. The sodium polyacrylate water-absorbing material with excellent water absorption properties obtained through a special production process has a particularly strong water absorption capacity and high water retention capacity. High molecular weight polymer obtained by acrylic acid polymerization → high water retention capacity, can not squeeze the absorbed water through a simple physical method, and can repeatedly release water and absorb water.
