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


The anion exchange membrane, also called anion permselective membrane is a class of high molecular polymer membranes that contain basic active groups and have selective permeability to anions. They are also called ion-selective membranes. The anion exchange membrane is composed of three parts: the polymer main chain with a fixed group, that is, the polymer matrix (also known as the base membrane), the positively charged active group (ie, the cation), and the anion that can move freely on the active group.
The anion exchange membrane has a very wide range of applications. It is an important part of separation devices, purification devices, and electrochemical components. It plays an important role in the fields of Chlor-alkali industry, water treatment industry, heavy metal recycling, wet metallurgy and electrochemical industry Role. In recent years, with the development of new chemical power sources, the application of anion exchange membranes as battery separators in flow energy storage batteries, alkaline anion exchange membrane fuel cells, and new supercapacitors has also received attention and research.

Characteristics of Ion Exchange Membrane

  • High acid and alkali resistance, good chemical and physical structure stability
  • Membrane materials are made of acid-and alkali-resistant macromolecule materials. The tolerance of acid and alkali reaches 6 moL at room temperature. The interface is bonded by covalent bonds, and the structure is stable for a long time. There is no stratification or bubbling in use.
