钛与MMO涂层

Titanium mesh with MMO coating MMO coatings with Titanium anode (titanium mesh/titanium plate/titanium tube) are made of precious metal iridium salt coatings which is applying on titanium and sintering by high temperature. It is widely used in electroplating (high-demanded copper plating and gold plating of Printed circuit board industry), electrolysis and other hydrometallurgical industry. Preparation and application of have been a mature state which is 40 years history as so far. Comparing with the process of traditional platinum electrode in alkaline copper plating, titanium anode plating has unmatched been following advantages: 1. Technical features High-efficiency current, excellent anti-bacterial rot; long term service life of electrode; higher current density withstand and higher current density operate: <10000A/M2 (It belongs to oxygen evolution anode basing on industrial purity titanium)2. High catalytic activityAs all is well know, platinum-plated electrode is a high peroxo potential electrode (1.563V according to mercury sulfate) and the MMO anode is a low oxygen evolution potential electrode (1.385V according to mercury sulfate) which is more easily oxygen evolution in the anode oxygen zone. Therefore,the voltage of electrolysis is relatively lower and save more energy. This phenomenon in the copper foil after alkaline copper plating has been clearly manifested.3.Non-pollution MMO anodeAnode coatings are iridium ceramic oxides of precious metals which got an excellent stability, hardly soluble in any acid-alkalic solution, 20-40μm MMO coating oxides and less total volume of MMO coating oxides .Therefore, MMO anode will not cause pollution by electroplating solution. This is basic asPlatinum-plating electrode.4. Cost-effectiveWorking lifetime is the same as the platinum-plating electrode (3.5mm coating thickness), The price of MMO anode is 80% of pure platinum-plating electrode.The electrochemical stability of MMO anode electrode is more excellent in electrolyte solution for alkaline copper-plating, also it has an excellent activity and durability. Compared the cost between PT and MMO anode electrode, MMO anode would be the best choice5. with titanium anode was forbidden (the chloride of sulfuric acid electrolyte exists in this current environment, MMO platinum coating will be dropped after working a period time). However, choosing the suitable size of MMO anode could solve this matter and achieve the performance advantages successfully in thisApplications6. Less maintenance. It doesnt need to stop the production line to clean and replenish the anode. Also no need to do the replacement of anode bags and re-coating (improving the productivity and cost reduction)7. The service life of MMO anode depends on coatings, operating current density and plating chemical agents
