Hydrogel moldings for absorbing or releasing liquid

【Task】 Providing a water-absorbing and water discharge excellent in hydrogel moldings. A A water-soluble organic polymer having organic acid salt structure or an organic acid anion structure, a silicate, a hydrogel containing a dispersant of the silicate was pulverized, mixed with a compound having a divalent or more positive charges, by cross-linking process, characterized in that the water retention, excellent hydrogel water absorption and drainage properties are obtained, hydrogel moldings. .BACKGROUND
