Using heat adhesive fibrous ion exchanger, reported in previous paper, the study of preparation of ion exchange membrane was carried out as follows.
1) The ion exchange paper is made of very fine fibrous ion exchanger.
2) After drying, the paper is heat-pressed under the pressure of 100_??_150kg/cm2, at 150°C, for a few minutes to form a membrane structure. The characteristics of the ion exchange membrane are as follows.
a) The ion exchange membrane has a well-uniformed cross section, in which the figure of the fibrous ion exchanger disappears initially.
b) Through the treatment of the above membrane in hot water, the micro cracks bring forth. This is available for decreasing the specific resistance and controlling the ionic transport coefficient number.
3) The main characteristics of the ion exchange membrane under optimum condition are as follows:
Through this method, various membranes - membrane of cation-anion stucked together, fiber reinforced membrane and cation-anion mosaic membrane are easily prepared.
