Chlor-alkali Ion Exchange Membrane
Chlor-alkali Ion Exchange Membrane covers ion-selective membranes separating the electrolyzer's electrode compartments. Selective transport can depend on pores, solubility-diffusion or fixed ionic groups; module form alone does not establish the mechanism.

Product & engineering
Understand the product.
Chlor-alkali Ion Exchange Membrane is used in electrolyzers at electrolysis plants in which brine is decomposed. It plays a key part in manufacturing caustic soda (sodium hydroxide)/caustic potash (potassium hydroxide), chlorine, and hydrogen-basic chemical products required in our daily lives. The chlor-alkali processes rely on an ion-exchange membrane to separate the sodium and chloride ions of the sodium chloride.
A membrane caustic soda plant with manufacturing capacity of 10 K MT demands 300 sq.m Chlor-alkali Ion Exchange Membrane. The replacement cycle of the membrane is usually 2.5-4 years.
The distinguishing feature is ion-selective membranes separating the electrolyzer's electrode compartments. Compare selectivity and electrical resistance under the actual electrolyte, temperature and hydration. Swelling, crossover and chemical attack can change both efficiency and service life. A sheet's color or thickness cannot establish its fixed-charge chemistry or suitability for a particular electrochemical process.
What turns activity into demand
Separation throughput creates demand through validated area, flux and replacement life. Feed pretreatment, recovery and cleaning determine module count.
The commercial boundary
Separate sheet, element and packaged system; water filtration, gas separation and ion transport use different mechanisms and units.
Which membrane properties govern ion transport and stability together?
