1. Introduction I produced the precious metal oxide anode is covered with a electro-catalytic activity of metal oxides (iridium, ruthenium and titanium oxides) in titanium substrate (ASTMB 265 primary titanium) constituted on oxide coatings polarization is small and the consumption rate is very low, the oxide layer by adjusting the composition, it can be adapted to different environments, such as sea water, fresh water, soil medium, a noble metal oxide anode and the strip-like conductive titanium sheet welded cross the composition of the anode mesh, mesh anode cathodic protection system as an auxiliary anode cathodic protection is widely used at home and abroad the new tank floor. 2, Specification: Product Name Specification Dimensions (W × m) Remarks precious metal oxide anode strip MMOD 6.35 × 0.635 general 152.4 meters per roll
