MMO Titanium Anode, also called as MMO anode. MMO is the abbreviation of Mixed Metal Oxide. The substrate is titanium, which is coated with precious metal oxide to gain good electrocatalytic activity and conductivity. It’s also known as DSA anode (Dimension Stable Anode), DSE (Dimension Stable electrode), PMTA (Precious Metal-coated Titanium Anode), OCTA (Oxide Coated Titanium Anode), ATA (Activated Titanium Anode, or NMCA (Noble Metal Coated Anode).

MMO commonly works with Titanium Conductor Strip as cathode protection. Noble metal oxide anode is composed of a layer of metal oxides (such as ruthenium, iridium, platinum, etc.) with electrocatalytic activity on titanium substrate. Oxide coating has small polarization and low consumption rate. By adjusting the composition of oxide layer, it can be adapted to different environments, such as seawater, fresh water and soil. Because precious metal oxide anode has the advantages that other anodes do not have, it has become one of the most ideal and promising auxiliary anode materials.

MMO Titanium Anode Ribbon for the cathodic protection:

The MMO titanium anode ribbon is a kind of insoluble anode (DSA anode). A layer of precious metal oxide with high electrocatalytic activity was coated on the surface of the strip by traditional thermal decomposition method. It is usually used for cathodic protection of tank bottom and reinforced concrete structure on the ground.

The application fields of MMO Titanium Anode Ribbon in impressed current cathodic protection are as follows:

Anti-corrosion of pipeline inner wall
Underground storage tank, ground storage tank and water storage tank
Condensate tank, heat exchanger, water treatment equipment
Anti-corrosion of ship, pavement, bridge and building steel body
Continuous horizontal ground bed, discontinuous horizontal ground bed and shallow buried vertical ground bed

Method of Use

Generally, it is laid vertically with the Titanium Conductor Strip as the auxiliary anode of impressed current cathodic protection. The cross points are spot welded with a special welding machine to form a grid grid grid. The connection of electrified points is connected by special anode joint, which is simple to install and convenient to construct.

Note: the service life and output current of different requirements can be designed and produced by adjusting the coating ratio. The type, thickness and anode size of MMO strip anode coating can be customized according to the user, depending on the required current density, medium environment and design life.

Application: it is applied to the bottom protection of various large storage tanks. In application, it can be directly laid in wet or salty sand without any carbon based filling materials.

Usage environment:

Good sandy soil environment
In the environment of chlorine evolution, oxygen evolution or both
It is usually used in tank bottom and reinforced concrete structure.
