Titanium anode (MMO) is composed of a noble metal iridium coating on titanium substrate by high temperature sintering, are widely used in electroplating (deep hole PCB industry high copper electroplating, plating, electrolysis) wet metallurgy industry. The preparation and application of electrode has been quite mature, it has been 40 years of history, compared with the traditional platinum electrode in alkaline copper plating process, titanium anode has the advantages of platinum electrode can not be compared:

1. technical characteristics

The current has high efficiency, excellent antibacterial corrosion performance, long electrode life, and higher current density. The current density of operation is less than 10000A/M2, which belongs to the oxygen evolution anode with the industrial pure titanium as the base.

2. high catalytic activity

As everyone knows, platinum electrode is a high oxygen potential (1.563V, relative mercurous sulfate electrode), MMO anode is a low oxygen overpotential (1.385V mercury sulfate) electrode, more easily in the anodic region for oxygen evolution. Therefore, electrolysis, the voltage is relatively low, more savings electrical energy. This phenomenon with alkaline copper in the copper foil, has been clearly reflected.

3. pollution-free MMO

The anodic coating is ceramic oxide of iridium oxide, the oxide is a fairly stable, almost insoluble in any acid, and the oxide coating is about 20-40 m, the overall amount of coated oxide is less. Therefore, MMO will not cause pollution to the anode electroplating solution, and that the platinum electrode is basically the same.

4. high cost performance

Has maintained a platinum electrode (coating thickness 3.5mm) as the service life of MMO anode price is about 80% platinum electrode, MMO electrode has better electrochemical stability in alkaline copper plating electrolyte, and the electrolytic has excellent activity and durability. From the analysis of the cost of the company's MMO and PT anode electrode on the MMO electrode obvious economic benefits.
