Example Embodiment
[0019] Example 1: As shown in Figure 1 and Figure 3, the heterogeneous ion exchange membrane is divided into anion exchange membrane and cation exchange membrane. It is composed of a membrane 1 and a reinforced mesh 2 embedded between the two membranes 1. The reinforced mesh Cloth 2 is composed of an inert reinforced mesh with ion exchange groups after treatment.
[0020] The membrane is manufactured by a well-known technology. The inert mesh is coated with ion exchange resin to make it carry ion exchange groups, and then the treated reinforced mesh is embedded between the two membranes.
Example Embodiment
[0021] Example 2: As shown in Fig. 2 and Fig. 4, the heterogeneous ion exchange membrane is divided into anion exchange membrane and cation exchange membrane. It is composed of a membrane 1 and a reinforced mesh 2 laminated on both surfaces of the membrane 1. The reinforced mesh It is composed of ion exchange fibers of different lengths.
[0022] The membrane is manufactured by a well-known technology, the length of ion exchange fibers is woven into an active mesh, and then the active reinforcing mesh is laminated on both surfaces of the membrane.
Example Embodiment
[0023] Example 3: As shown in Figures 2 and 4, the heterogeneous ion exchange membrane is divided into anion exchange membrane and cation exchange membrane. It consists of a membrane 1 and a reinforced mesh 2 laminated on both surfaces of the membrane 1. The reinforced mesh It is composed of inert mesh cloth modified by bonding ion exchange fibers of different lengths.
[0024] The diaphragm is manufactured by a well-known technology. Ion exchange fibers of different lengths are bonded to the reinforced mesh, and then the modified reinforced mesh is laminated on one surface of the diaphragm, and the other surface of the diaphragm is laminated with inert reinforcement. net.
