Non-asbestos diaphragm in chlorine-alkali electrolysis
For decades in diaphragm electrolysis, asbestos containing diaphragms have been utilized to separate the anode and cathode compartments. Due to the harmful characteristics of asbestos. its world-wide prohibition in diaphragm manufacturing is expected. The objective of this work was focussed on the development of a diaphragm with sufficient mechanical and chemical stability to substitute the modified asbestos diaphragm currently used. Suitable materials for the manufacture of non-asbestos diaphragms were identified and a deposition technology was developed which fulfils the requirements of industrial production plants.
