Manufacturers introduce the application of titanium anode!

Because of its excellent electrochemical and mechanical properties, the surface modified titanium anode plate materials can be widely used in chlor-alkali industry, chemical industry, metallurgy, electroplating, water treatment, environmental protection, Marine, cathodic protection and other fields. Specific analysis is as follows:

1. Titanium anode for chlor-alkali industry

Titanium anode for chlor-alkali industry Titanium electrode was used in chlor-alkali industry by DeNora Company in Italy as early as 1968. At present, the total production capacity of caustic soda in China is 730× 104T (1998), while the United States and other countries are 3000× 104T, basically using titanium anode electric tank. The domestic type 30 titanium anode tank needs 210kg titanium material for each set, so the titanium electrode used in the chlor-alkali industry all over the world will consume titanium material about 1.54× 104T, is an effective way to promote the application of titanium material, at the same time, precious metal surface modification can effectively improve the deep processing value of titanium metal, can achieve large capacity and high profit.

2. electrodeposition extraction of non-ferrous metal with titanium anode

Electrodeposition extraction of metal using insoluble anode, so that after leaching, purification treatment of the electrolyte to extract metal ions in the cathode reduction, preparation of pure metal. Electrolytic metallurgy has occupied a large proportion in hydrometallurgical industry. The non-ferrous metals produced by electrolytic metallurgy include Zn, Cd, Cu, Mn, Co, Cr and so on. The difficulty of metal extraction by electrodeposition is to select suitable anode material. The anode is required to be stable, corrosion-resistant, and can be used for a long time. It has good electrocatalytic activity for the anode process, so as to reduce the anode reaction overpotential and cell voltage. In recent years, coated titanium electrodes have been widely used in the metal extraction industry by electrodeposition. As hydrometallurgy technology becomes the mainstream technology, precious metal surface modified titanium anode plate materials will become the key materials in this field.

3.electrolytic method to obtain ionized water (basic ionized water and acidic ionized water) titanium anode

Normal healthy human ph ranges from pH7.36 to 7.4 (which is necessary for the body to carry out normal metabolism. But with the high living standard, the ratio of acidic food (fish, meat, eggs, sugar, rice and alkaline food (vegetables, fruits, milk, etc.) in people's diet far exceeds the normal ratio (1:2). In addition, urban environmental pollution and the accelerated pace of life caused by the spirit of Zhang, so that the body's PH balance system imbalance, leading to the formation of acidic constitution. And acidic constitution, which is sub-health state, is an important cause of modern diseases (high pressure, hyperlipidemia, hyperglycemia, etc.). Long-term consumption of alkaline water beverage, will make people from the acid constitution to the normal state. Alkaline ionized water can directly treat chronic dysentery, dyspepsia, gastrointestinal fermentation, excessive acid and other four diseases, the other modern diseases is through reform.Electrolytic ionized water generator for household use. Is the tap water through the filtration, through the electrolytic action, in the cathode area to produce basic ionized water, in the anode area to produce acidic ionized water. The anodes and cathodes of ionized water generators at home and abroad used titanium plated platinum electrodes. Platinum plated titanium electrode is expensive and scarce. Titanium plated platinum pole needs to be imported from abroad, the tariff is particularly high. As a result, the price of ionized water generator is high and it is difficult to sell in China. Using precious metal surface modified titanium anode plate material, the electrolytic cell can be operated under the high cell voltage of 30V, the general electrolytic cell working voltage is 3-4V, the output of high quality basic ionized water and acid ionized water, the performance of all aspects can be compared with titanium platinum plated electrode. And the precious metal surface modified titanium anode has low price, which is conducive to localization.

4. Titanium anode for electroplating industry

(1) Gold plating

The gold plating process used to use titanium plating platinum electrode, one is expensive, the other is the need to import from abroad, there are also two problems: the oxidation of gold ions into trivalent gold ions, reduce the current efficiency, oxidation damage citric acid buffer, destroy the stability of plating solution. The plating solution can be kept stable by using precious metal surface modified titanium anode plate material, and the surface state of the plated parts is no different from that of the platinum plated titanium electrode. Precious metal surface modified titanium anode plate material price is cheap, is 1/3 of the price of titanium plating platinum, and do not need to import.

(2) Chromium plating

Lead - based anodes are usually used for chromium plating. In the electroplating process, lead chromate with poor electrical conductivity is easy to form on the surface of lead electrode, which increases the voltage of the tank and even causes the anode not to conduct electricity. When NORMAL PRODUCTION, MUST UNDERTAKE SCRUB REGULARLY, INCREASED LABOR intensity thus ALREADY, POLLUTED THE ENVIRONMENT AGAIN. Chrome plating solution is made of sulfuric acid and chromic acid, which is highly corrosive. The current density of chromium plating is very high, up to 50 A/dm2. Such a harsh plating environment, the general electrode material is difficult to adapt to. Using precious metal surface modified titanium anode plate material can greatly reduce the above problems.

5. Titanium anode for water treatment

In the processing of industrial water, hospital sewage treatment, electroplating factory of cyanide waste water treatment, as well as the power plant circulating water cooling to adopt high performance in processing of titanium anode materials, precious metal surface modification of titanium anode materials can effectively purify processing, make the scale inhibition rate is more than 94%, descaling rate is greater than or equal to 94%, the sterilization rate is more than 97%, the algae removal rate was 100%, Full compliance with sewage discharge standards.
