Titanium anode is mainly used in industrial production such as chlor-alkali and sodium hypochlorite, electrolytic synthesis of organic compounds, sewage treatment, seawater desalination, electrolysis of dilute brine, anode for sodium hypochlorite, anode for sodium chloride electrolysis, disinfection of tap water, series of electrode products for sewage treatment, seawater desalination Electrodes, elimination of plankton in industrial circulating water, etc.
The main categories are: platinum titanium electrode, lanthanide titanium electrode, super titanium electrode, lanthanide titanium electrode, noble metal plating electrode group.
Today, the main introduction is platinum titanium anode for electh
The tap water is filtered and passed through an electrolysis plate (platinum titanium anode) of the ion water generator for electrolysis. The positively charged ions such as potassium, sodium, calcium and magnesium in the water flow to the cathode to form alkaline ionized water; the negatively charged ions such as chlorsulfuron flow toward the anode to form acidic electrolyzed water. The electrolysis water machine uses activated carbon as a filtration layer, filters the tap water to purify it to the standard (to meet the national drinking water standard), and then generates two kinds of active water by electrolysis, that is, electrolyzed water. The concentrated electrolyzed water (for drinking) is concentrated on the cathode; the acidic electrolyzed water is concentrated on the anode.
Electrolyzed water is popular as a sterilization treatment technology with good sterilization effect, strong practicability and no secondary pollution. The functional water is produced by electrolyzing drinking water or a trace amount of light brine through a titanium electrode, and is widely used in an electrolysis machine.
(1) The use of electrolysis produces hypochlorite, neo-oxygen, hydroxyl radicals and other strong oxidizing substances to kill microorganisms.
2 The electrolysis electrode is directly applied to the microorganism to cause it to die.
3 alkaline ionized water can directly treat a variety of diseases, effectively improve the body’s metabolic function, eliminate harmful acidic metabolites, and enhance the body’s ability to prevent and improve disease resistance.
4 Acidic ionized water has the effect of inhibiting bacterial growth, disinfection and astringent, and the effect is the same as that of cosmetic astringent water, and applying strong oxidizing property for sterilization and disinfection treatment.
Platinum titanium anode for electrolytic ionized water is an insoluble anode. The platinum plating layer is firmly bonded to the titanium substrate and has stable performance. It can replace pure gold and pure platinum anode and is used in gold and other precious metal plating tanks. Appearance shapes are: mesh, plate, tube, rod, filament (minimum diameter 1 mm), the largest processing size: 1200 × 1500mm; surface silver white, metallic luster.
Technical characteristics: high current efficiency; excellent corrosion resistance; long electrode life; electrode shape can be designed according to user requirements; electrode base can be reused many times; no pollution to the medium (electrolysis); can withstand higher Current density.
Applicable PH value: 0.1 ~ 14; Platinum thickness: 0.5 ~ 25 microns, according to user’s use; operating current density: <10000A / sqm; electrode type: oxygen evolution type electrode; electrode substrate: pure titanium.
Applications: Non-ferrous metal production and recycling: Electrodeposition of copper, nickel, diamond, electrolytic production of high-purity metals; electroplating: precious metal plating (gold, silver, antimony, platinum and rhodium), surface electroless copper, nickel, zinc, pot , electroplating chrome, printed circuit board electroplating; metal recycling: electroplating solution wastewater treatment; electrochemical synthesis: electrolyzed plum water, seawater desalination, persulfate preparation, oxidant regeneration, radioactive pollutant treatment; cathodic protection: cathode of pipeline Protection, heat exchanger cathodic protection, coastal steel structure construction, water pipelines and sea water pump valves.
The platinized anode is characterized by its three outstanding effects as an electrode material:
1. It is stable, corrosion resistant and can be used in various media.
2. For the oxygen evolution reaction, the overpotential is very high
3. For the hydrogen evolution reaction, the overpotential is very low. The application range of the titanium platinized electrode is also relatively wide. It has the best performance with other advantages, and the disadvantage is that the price is expensive.
The platinized layer is electrodeposited in an acidic or alkaline plating solution after etching with a titanium substrate, and then a platinum plating layer is obtained, which is currently an expensive electrode material.
