摘要： A gelling material is composed of water-absorbent resin 12 wrapped in a bag composed of two laminated water-soluble sheets 1.1, the water-absorbent resin being prepared so as to enable the bag to be disintegrated by an inner pressure generated when an expanded volume of the water-absorbent resin by absorbing water through the bag exceeds a maximum volume capacity. When the gelling material is added to the aqueous fluid, the water-absorbent resin 12 is spread in the aqueous fluid at a stroke, and is diffused uniformly. Thus, the water-absorbent resin 12 is brought fully in contact with the aqueous fluid. Since this enables the aqueous fluid to be gelled in a short period of time, the aqueous fluid can be processed speedily. Even the aqueous fluids, which are difficult to be handled by the conventional gelling material, can be gelled conveniently in a short period of time, and the resulting gell can be easily handled, thereby enabling an easy disposal of the aqueous fluids, i.e., the gell. Additionally, since the water-absorbent resin is spread in the aqueous fluid at a stroke, and is diffused uniformly, a troublesome operation of agitating the aqueous fluid can be eliminated during the gelling process, thereby enabling a simplified gelling process.
摘要翻译：凝胶材料由包裹在由两层叠水溶性片材1.1构成的袋子中的吸水性树脂12组成，吸水性树脂被制备成使得袋子能够通过膨胀容积产生的内部压力而分解的吸水性树脂通过吸收水通过袋超过最大体积容量。当将水凝胶材料添加到水性流体中时，吸水性树脂12在水溶液中中和地扩散，并均匀扩散。因此，使吸水性树脂12与水性流体完全接触。由于这样能够使水性流体在短时间内凝胶化，所以能够快速地处理含水流体。即使是常规胶凝材料难以处理的含水流体也可以在短时间内方便地凝胶化，并且可以容易地处理所得的凝胶，从而能够容易地处理水性流体，即，凝胶。此外，由于吸水性树脂一度在水性液体中扩散，并且均匀地扩散，因此在胶凝过程中可以消除搅拌含水流体的麻烦的操作，从而能够进行简化的胶凝化处理。

摘要： A method of preparation of an absorbent composite in which an aqueous solution containing a water-soluble radical polymerization initiator and a water-soluble ethylenically unsaturated monomer which can be converted into an absorbent polymer by polymerization is applied to a substrate, and the monomer is polymerized while the substrate to which the aqueous solution is applied is, on both the sides, held in contact with polymerization-inert surfaces facing each other. A continuous manufacturing method includes the sequential steps of continuously passing a substrate through (1) a region applying to the substrate an aqueous solution containing a water-soluble radical polymerization initiator and a water-soluble ethylenically unsaturated monomer which can be converted into an absorbent polymer by polymerization, and (2) a region of polymerizing the monomer while maintaining the substrate, on both the sides, in contact with polymerization-inert surfaces facing each other.

摘要： A water-absorbent resin is produced by crushing a mass of crosslinked hydrogel polymer having high adhesion and elastic properties without kneading it, and drying the crushed crosslinked hydrogel polymer. In the case when the crosslinked hydrogel polymer includes cells therein, the crosslinked hydrogel polymer is crushed so as to restrain reduction in the number of cells contained in the crosslinked hydrogel polymer. The crosslinked hydrogel polymer is crushed by any of crushing methods including: shearing the crosslinked hydrogel polymer with a fixed blade and a rotary blade; cutting the crosslinked hydrogel polymer with a cutter having a pair of rotary blades that are mounted on different shafts and rotate while at least partly overlapping each other; cutting the crosslinked hydrogel polymer with a cutter having a rotary blade using a lubricant; and crushing the crosslinked hydrogel polymer after freezing. With the use of the above methods, it is possible to industrially and easily mass-produce porous water-absorbent resins with excellent absorption properties while restraining reduction in the number of cells contained in the crosslinked hydrogel polymer.
