1. Technical characteristics
High current and high efficiency, excellent antibacterial corrosion performance; long electrode life; can withstand higher current density, operating current density: <10000A/M2 is an oxygen evolution type anode based on industrial pure titanium.
2. High catalytic activity
It is well known that the platinized electrode is a high peroxygen potential (1.563V, relative to mercuric sulfate) electrode, while the MMO anode is a low oxygen evolution overpotential (1.385V vs. mercuric sulfate) electrode, which is more in the anode oxygen evolution zone. Easy to analyze oxygen. Therefore, the cell pressure is also relatively low during electrolysis, which saves energy. This phenomenon has been evident in the copper foil post-treatment of alkaline copper-plated walls.
3. Pollution-free MMO
The anodic coating is a ceramic oxide of noble metal cerium, which is a relatively stable oxide and is hardly soluble in any acid or alkali.
And the oxide coating is about 20-40 Um, and the amount of overall coating oxide is small. Therefore, the MMO anode does not pollute the plating solution, which is basically the same as the platinized electrode.
While maintaining the same service life of the platinized electrode (coating thickness 3.5mm), the price of the MMO anode is about 80% of the platinized electrode. The MMO electrode has better electrochemical stability in the alkaline electroplating copper electrolyte. It has excellent electrolysis activity and durability. From the analysis of the cost of the company’s MMO anode and PT electrode, it is obvious that the MMO electrode is economical.
5. Due to the use of pulse period reversal (PPR) technology in the application of copper in printed circuit boards, we know that the use of platinized dissolved anodes is prohibited (chlorides in sulfuric acid electrolytes are present in this current environment, after a while) Peel off the platinum layer). However, the use of dimensionally stable anodes avoids this phenomenon and allows the insoluble anode technology to successfully achieve performance advantages in such applications.
6. Anode maintenance is minimal. There is no need to stop the production line to clean and replenish the anode, replace the anode bag and re-coat the anode (increased productivity and reduced labor costs;
7. The life of the insoluble anode depends on the type, working current density and contact of the plating chemical;
