Professional Perfluorinated Ion-Exchange Membrane(PIEM) and Selective Ion Exchange Membrane manufacturer in China

Perfluorinated Ion-Exchange Membrane for  Electrolysis

The Ion-Exchange Membrane SY-14P series 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 Chlor-alkali Membrane SY-14P series 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 electrolyzing cell conditions.

1, Measurements taken with membrane conditioned to 23°C,50% RH.
2, Conductivity measurements at 23°C,100% RH.
3, A base titration procedure measures the equivalents of sulfonic acid in the polymer, and uses the measurement to calculate the acid capacity or equivalent weight of the membrane.
4, Water content of membrane conditioned to 23°C and 50% RH (dry weight basis).
5, Water uptake from dry membrane to conditioned in water at 100°C for 1hour (dry weight basis ).
