Abstract
(EN)
The purpose of the present invention is to provide a particulate water absorbing agent having both a high water absorption multiplying factor and a high water absorption rate and a method for manufacturing the same. The present invention is a particulate water absorbing agent for which CRC is 30 - 50 g/g, wherein the weight average particulate diameter (D50) is 200 -600 µm, and the DRC index given by the following formula is a specific value (for example, 43, 30, or 20) or less: DRC index = (49 − DRC5min [g/g])/(D50 [µm]/1000).
(FR)
La présente invention vise à fournir un agent d'absorption d'eau particulaire ayant à la fois un facteur de multiplication d'absorption d'eau élevé et un taux d'absorption d'eau élevé, et son procédé de fabrication. La présente invention concerne un agent d'absorption d'eau particulaire pour lequel le CRC est compris entre 30 et 50 g/g, le diamètre particulaire moyen en poids (D50) étant compris entre 200 et 600 µm, et l'indice DRC donné par la formule suivante est une valeur spécifique (par exemple, 43, 30 ou 20) ou moins : indice DRC = (49 − DRC5min [g/g])/(D50 [µm]/1000).
