Abstract:
A process for storing a particulate free-flowing water-absorbent resin, which comprises a step of storing a particulate water-absorbent resin in a storage apparatus where said particulate water-absorbent resin is obtained by pulverizing a dry water-absorbent resin product,with the process for storing being characterized by all of the steps of: (1) heating at least one portion of a surface of said storage apparatus making contact with the particulate water-absorbent resin, where said storage apparatus is heated from the outside, (2) maintaining the temperature of at least one portion of said surface of a storage apparatus making contact with the particulate water-absorbent resin where said surface is at a temperature of 30 to 150Â° C., and (3) maintaining the temperature of at least one portion of a surface of said storage apparatus making contact with the particulate water-absorbent resin where said surface is at a temperature above a temperature that is lower than a temperature of the particulate water-absorbent resin by 20Â° C., when storing the particulate water-absorbent resin.
