The processing methods of platinum anode
Platinum titanium anode, also known as platinum plated titanium anode, platinum titanium anode or titanium based platinum plated anode, belongs to insoluble anode. Using electroplating process, platinum is plated on the surface of specially treated titanium substrate, which can be fully platinum-plated or partially platinum plated. Platinum can also be plated on composite materials such as copper clad titanium. Platinum coated titanium electrodes can also be formed by high temperature coating.
Characteristics of platinum-titanium anode
High current efficiency; Excellent corrosion resistance; Long electrode service life; The electrode substrate can be reused many times; No pollution to the medium (in the case of electrolysis); Can withstand higher current density.
The appearance shapes of platinum-titanium anode usually include: Mesh, plate, tubular, rod, etc. and can also be designed according to user requirements;
- Platinum plating thickness: 0.5 ~ 5 microns;
- Applicable pH value: 1-14; Depending on the user’s purpose;
- Surface color: Silver-white, with metallic luster;
- Operating current density: < 10,000 A/sqm;
- Electrode substrate: Pure titanium Gr1/Gr2.
Platinum titanium anodes are used in those industries?
- Electrolytic water hydrogen production: platinum titanium electrode is widely used in the field of electrolytic water hydrogen production, and its efficient catalytic activity makes the electrolytic process more efficient.
- Cathodic protection: In order to prevent the hull, dock steel wharf, bridge trusses, etc. from being attached to Marine organisms and corroded by seawater, platinum titanium anode can be used as an auxiliary anode impressed current cathodic protection system. This protection system is widely used in seawater, fresh water, soil and other metal parts anti-corrosion protection.
- Non-ferrous metal production and recycling: Platinum titanium anodes can be used for electrodeposition to produce non-ferrous metals such as copper, nickel, and diamonds, as well as electrolysis to produce high-purity metals. In addition, it can also be used for electroplating wastewater treatment to achieve metal recovery.
- Electrochemical synthesis: Platinum titanium anode has a wide range of applications in the field of electrochemical synthesis, such as electrolytic seawater, seawater desalination, persulfate production, oxidant regeneration and radioactive pollutants treatment
