Products Description
MMO Titanium Tubular Anode, full name Titanium-based Mixed Metal Oxide Tubular Anode, also called DSA (Dimensionally Stable Anode) insoluble anode. It adopts seamless Grade1 pure titanium tube as substrate, coated with noble metal oxide catalytic layer via high-temperature thermal decomposition. It will not dissolve during electrolysis, maintain constant pole distance and uniform current distribution, the core electrode for Impressed Current Cathodic Protection (ICCP) and industrial electrolysis, suitable for soil, seawater, fresh water, acid & alkaline electrolyte harsh environments.
