Titanium Mesh for Chlor-Alkali Production

Titanium mesh for chlor-alkali production serves as the core anode component in ion-exchange membrane electrolyzers. During saturated brine electrolysis, it efficiently catalyzes chloride ion oxidation for chlorine evolution, with a chlorine evolution potential <1.13V. This mesh is a key recyclable material for DONGSHENG’s industrial scrap recovery operations.
