DIAPHRAGM CELLS

摘要

MD 29465 An electrolytic diaphragm cell for the production of halogen, hydrogen and an alkali metal hydroxide solution by electrolysis of an aqueous alkali metal halide solution the cell comprising a plurality of anodes vertically mounted at one side of the cell, a cathode box mounted at the opposite facing side of the cell providing cathodes between adjacent anodes, and a hydraulically permeable diaphragm between adjacent anodes and cathodes, comprising a sheet of a porous non-melt-processable fluorinecontaining polymer connected to an upper and lower slotted supports of a melt-processable fluorine--containing polymer by means of strips of a meltprocessable fluorine-containing polymer fused to the upper and lower edges of the diaphragm. The diaphragm preferably comprises a plurality of sheets of the non-melt-processable fluorine-containing polymer which are joined together by joining strips of melt-processable fluorine-containing polymer fused into the sheets at or near juxtaposed edges of the sheets.
