ION EXCHANGER, WATER TREATMENT DEVICE PROVIDED WITH SAME, AND HOT WATER SUPPLY DEVICE

WIPO Patent Application WO/2014/091726

A1

[Problem] To provide an ion exchanger capable of efficiently adsorbing ions. [Solution] The present invention is provided with: a porous positive-ion exchanger (2) which is formed into a sheet shape, and which has, mixed therein, binder particles (5) and positive-ion-exchange resin particles (4); and a porous negative-ion exchanger (3) which is formed into a sheet shape, and which has, mixed therein, binder particles (7) and negative-ion-exchange resin particles (6). The positive ion exchanger (2) and the negative ion exchanger (3) are bonded to each other to form an interface, and the capacity of the negative ion exchanger (3) is configured so as to be greater than that of the positive ion exchanger (2). As a result, a porous ion exchanger (1) is formed and ion adsorption performance is increased. Furthermore, the capacity of the negative ion exchanger (3) is set so as to be greater than that of the positive ion exchanger (2), thereby ensuring reclamation performance of the ion exchanger with respect to ion adsorption performance, and enabling ion adsorption and reclamation to be performed efficiently.
