What is "super absorbent resin"? Talk specifically

Polymer water-absorbent resin has been widely used in disposable sanitary products, agricultural fields, optical cable industry and waterproof industry, mainly including infant care sanitary products, women care sanitary products and adult incontinence sanitary products, because of its large water absorption capacity, strong water retention capacity and many properties of polymer, such as mechanical properties, plasticity, easy processing and easy use. Because the liquid treated by the above products is not simple water, but a mixture containing salt, minerals and blood. Therefore, we use physiological saline and artificial plasma when testing polymer absorbent resin and diaper, which is more in line with the actual use. The diaper is an absorbent core composed mainly of wood pulp and polymer absorbent resin, as well as harmless cloth, paper towel, elastic band and adhesive. Consumers' requirements for diapers are that babies will not leak, absorb water and retain water when wearing them, and make the baby's skin surface dry and comfortable to wear. The performance requirements of diaper manufacturers are mainly manifested in water retention, penetration speed, liquid diffusion and leakage prevention. The raw materials of diapers make different contributions to each performance of diapers. For example, the innocuous cloth on the surface guide layer has a great influence on the penetration speed and liquid diffusion range, while the polymer water-absorbent resin has a great influence on the re-infiltration performance of diapers. The appearance of polymer water-absorbent resin has led to the revolution in the use and production of diapers. Because of its high water absorption and good water retention performance, modern disposable diapers bring convenience to mothers and comfort to babies.
