The Chlor-Alkali membranes are made from ion-exchange polymers. The perfluorinated polymer provides chemical and thermal stability similar to that of fluoropolymer resin.The polymer is, therefore, permeable to many cations and polar compounds—their size and electrical properties determine their mobility through the polymer—and can almost completely reject anions and non-polar species
Perfluoroionic Ion-exchange membranes are widely used in
Chlor-alkali industries, electro-dialysis, recovery of copper from
etching solutions, synthesis for gold potassium cyanide, chlorine
dioxide, and electrochemical reaction for amino acid. The membrane
performs as a conducting separator and solid electrolyte in a
variety of electrochemical cells which require the membrane to
selectively transport cations across the cell junction.
The Ion-exchange membranes are reinforced membranes based on
chemically stable perfluorosulfonic acid (PFSA) copolymer.
Incorporation of the PTFE mesh reinforcement improves the
mechanical property of the composite membrane and allows the
membrane to restrict its swelling. The membranes show significant
improvements in features such as better resistance to chemical
attack and longer operating durability under electrolysing cell
conditions.Â
Excluding
China, there are three suppliers for chlor-alkali ion-exchange
membrane all over the world, we compared the properties with the
three suppliers as follows:(Reference Standard):
