る。[Problems to be solved by the invention] After the membrane and gasket are laminated and installed in an electrodialyzer and electrodialysis operation is performed, when the membrane and gasket are attached and detached, the gasket and the fastening frame stick to each other and are easily peeled off. It may not be possible to do so. If you forcefully remove it, the gasket may crack or even break. In particular, in the case of an integrated membrane and gasket for a small electrodialysis device used for the purpose of simplifying the handling of the membrane and gasket, if the gasket and the fastening frame stick together, strong force will be applied to the joint of the integrated product during attachment and detachment. In some cases, the joint may come loose and the integrated product may separate.

FIG. 3 is a side view of the assembled members shown in the figures. To explain with these drawings,
The fastening frame 1 forming the electrode chamber is brought into close contact with both sides of the membrane/gasket laminate 2 in which the ion exchange membrane and the gasket or the ion exchange membrane, the semipermeable membrane, and the gasket are laminated, forming the current-carrying surface 5. Fasten and assemble as shown in Figure 2. An electrode liquid pipe 3 is attached to the fastening frame 1 so that a predetermined electrode liquid can be supplied into and discharged from the electrode chamber.

い。 Here, the ion exchange membrane is an anion exchange membrane,
Ion exchange membranes used in ordinary electrodialysis, such as cation exchange membranes, can be used without particular limitation. The semipermeable membrane is not particularly limited, and various neutral membranes such as those made of polyvinyl alcohol without ion selectivity can be used.

ことが必要である。 As the gasket, those used in ordinary electrodialysis such as rubber gaskets and plastic gaskets can be used. In particular, in the case of integrated membrane and gasket materials, materials such as ethylene/ethyl acrylate copolymer or ethylene/vinyl acetate copolymer can be used to bond gaskets to each other, or materials that can be used to bond gaskets to each other or the membrane and gasket. It is necessary that

することができない。 The surface roughening may be carried out by surface corrosion with a chemical, sputtering of ionic particles, etc., but it is preferable to use abrasive paper or abrasive cloth because of its simplicity and the fact that no chemical remains after treatment. As for the degree of surface roughening, it is desirable to use abrasive paper or abrasive cloth with a grain size of 400 to 800 from the standpoint of preventing liquid leakage and preventing adhesion between the gasket and the fastening frame. Using abrasive paper or abrasive cloth with a particle size of less than 400 may cause leakage;
The purpose of anti-sticking using abrasive paper over 800 cannot be achieved.

ができる。 Although the surface roughening of the present invention may be carried out in a large-sized electrodialysis device, it is particularly desirable to use it in a small-sized electrodialysis device with an effective current-carrying area of 10 cm 2 or less. By combining this with an integrated membrane and gasket, an electrodialysis device that is easy to handle can be obtained.

Particularly in the case of a membrane/gasket integrated product, it becomes possible to attach and detach the integrated product without separating it, which greatly improves the ease of handling.
