## Overview

The Electrodialysis Ion Exchange Membrane is a cutting-edge cation exchange membrane designed for high-performance desalination applications. With a film surface resistance of ≤ 2.9 Ω·cm2 and a dry film thickness of 50um, it offers exceptional ion selectivity and thermal stability, making it ideal for various water treatment processes.

## Description

Ion exchange membranes are thin films that selectively allow ions to pass through, roughly divided into cation exchange membranes and anion exchange membranes. In a cation exchange membrane, due to the fixed negative charge exchange group, only cations can pass through, while anions are repelled by negative charges and cannot pass through. The anion exchange membrane utilizes the opposite effect. The homogeneous ion exchange membrane adopts a synthesis method, with bonding between functional groups and no heterogeneous structure. Its is uniform, the membrane surface is small, it is not easy to leak, and its performance is excellent. It is widely used in membrane capacitor deionization, seawater desalination, desalination, and other processes. Product features: High selectivity, higher ion selective permeability, resulting in higher current efficiency. can control the power cost of the device at a lower level; significantly superior to polystyrene ion exchange membranes in terms. Specification: Film surface ≤ 2.9 Ω· cm2 (0.5MnaCl, 25 ℃); Selection permeability ≥ 96%; PH usage range 1-12; Dry film thickness 50um; Blasting strength ≥ 0.25MPa; Water permeability ≤ 0.1mL/h-cm2-MPa; Thermal stability ≤ 50 ℃.
