Platinum and titanium anodes are insoluble anodes. The platinum plating layer is firmly bonded to the titanium substrate and has stable performance. It can replace pure gold and pure platinum anodes and is used in gold and other precious metal plating tanks. Appearance shapes are: mesh, plate, tube, rod, wire (minimum diameter 1 mm), etc., the largest processing size: 1200 × 1500mm; the surface is silvery white, with metallic luster.
Technical characteristics of platinum titanium anode: high current efficiency; excellent corrosion resistance; long electrode life; the shape of the electrode can be designed according to user needs; the electrode substrate can be reused multiple times; no pollution to the medium (electrolysis situation); can Withstand higher current densities.
Platinum titanium anode suitable PH value: 0.1 ~ 14; Platinum plating thickness: 0.5 ~ 25 microns, according to user’s application; Operating current density: <10000A / sqm; Electrode type: Oxygen evolution electrode; Electrode base material: Pure titanium.
Platinum titanium anode application areas: non-ferrous metal production and recycling: electrodeposition production of copper, nickel, diamond, electrolytic production of high-purity metals; electroplating: precious metal plating (gold, silver, rhodium, platinum and ruthenium), surface chemical plating of copper, nickel, Zinc, pot, chromium plating, chemical plating of printed circuit boards; metal recovery: electroplating solution wastewater treatment; electrochemical synthesis: electrolytic plum water, seawater desalination, persulfate preparation, oxidant regeneration, radioactive pollutant treatment; cathodic protection: Cathodic protection of pipelines, cathodic protection of heat exchangers, coastal steel junctions
Structure, water pipelines and seawater pump valves.
The characteristics of platinum titanium anode is that it has three outstanding effects as an electrode material:
1. It is stable, corrosion-resistant, and can be used in various media
2. For the oxygen release reaction, the overpotential is high
3. For the hydrogen release reaction, the overpotential Very low titanium platinized electrode has a wide range of applications. It has the best performance compared with others, but the disadvantage is that it is expensive. The platinum plating layer is electrodeposited in an acidic or alkaline plating solution after the oxalic acid etching of the titanium substrate to obtain a platinum plating layer, which is currently a relatively expensive electrode material.
At present, there are other noble metal oxide coatings that can replace it, and the price is 1/3. Such as ruthenium iridium titanium anode, iridium tantalum titanium anode, etc.
As an electrode material, platinum is widely used in the fields of electroplating, electrolytic synthesis, electrochemical treatment of wastewater and fuel cells. Platinum electrodes have characteristics such as strong corrosion resistance, high catalytic activity, high oxygen evolution potential, and low hydrogen evolution potential. The anode material is also a cathode material with excellent performance. Except for a few mixed acids, platinum shows excellent corrosion resistance in hydrochloric acid, nitric acid, sulfuric acid, hydrofluoric acid, phosphoric acid and most electrolyte solutions. Many important electrochemical industry fields, such as the production of hydrogen peroxide, ammonium persulfate, electrolytic water, etc., can be used as anode materials. However, platinum resources are scarce and expensive. In particular, the area of electrode materials used in industry is large. It is not feasible to directly use pure platinum anodes in production, which limits the promotion and application of platinum electrodes in the electrochemical industry. In order to save electrode costs and platinum resources, titanium-based platinum anodes need to be used instead of pure platinum anodes. At present, the titanium-based platinum anodes mainly use the P salt plating process. The main problem of this process is the large waste of plating solution, high cost, and the electroplating of platinum The bonding force of the platinum metal layer is poor.
