| titleOfInvention | Method for producing water absorbent resin and method for improving liquid permeability |
| abstract | In the production of the water-absorbent resin, the physical properties of the water-absorbent resin, for example, liquid permeability, are improved and stabilized by a simple method without requiring a change of raw materials or expensive capital investment. A polymerization step of polymerizing an acrylic acid (salt) aqueous solution to obtain a hydrogel crosslinked polymer, a drying step of drying the hydrogel crosslinked polymer to obtain a water absorbent resin powder, and classifying the water absorbent resin powder And a surface cross-linking step of surface cross-linking the surface of the water-absorbent resin powder before or after the classification step, characterized in that the charge is removed in the classification step. |
