Fourth, the main application areas
1. Electrolytic production of chlor-alkali industrial chlorate industrial sodium hypochlorite
The chemical industry for producing chlorine gas, hydrogen gas and caustic soda by electrolyzing salt solution is called chlor-alkali industry. It is widely used in the modern electrochemical industry and plays an important role in the national economy.
In addition to the above, it is also possible to prepare a downstream product of hydrogen chloride (aqueous solution is hydrochloric acid), sodium hypochlorite, chlorinated guanidine, polyvinyl chloride (referred to as PVC Polyvinyl chloride polymer = PVC molecular structure), hydrogen peroxide and the like.
In the production of chlor-alkali, the pure saturated brine is used as the electrolytic solution, the titanium electrode is used as the anode, the iron mesh asbestos is used as the cathode, the anode chamber generates chlorine gas, the cathode chamber generates hydrogen and sodium hydroxide, and after purification, it is widely used in various industries. in production.

The electrode has high catalytic activity for chlorine evolution and has good electrocatalytic activity, mechanical stability and chemical stability for chlorine evolution. It is an irreplaceable electrode material in the chlor-alkali industry today, with a service life of more than five years.
2, electrolytic function water
Functional water is defined as water that has been subjected to artificial treatment to obtain various useful functions. Electrolyzed water is welcomed as a sterilization treatment technology with good sterilization effect, high 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.

4, cathodic protection
In the environment of steel, such as ocean, hull, bridge, etc., due to the corrosion of impurities and micro-batteries in steel, combined with the complex natural environment, although corrosion-resistant alloy steel is selected and the thickness of the material is increased, excellent corrosion-resistant paint is applied. Corrosion of structures is still very serious, which greatly threatens safe production, and cathodic protection is an important and convenient measure for effective protection of permanent steel structures in the ocean.
1) Using the applied current, the entire surface of the protected metal structure becomes a cathode, called impressed current cathodic protection.

It can work stably for more than 4,000 hours and has low cost. It will be an inevitable trend in the development of electroplating zinc and tin production at home and abroad.
Titanium electrodes are currently used in Japan, the United States, Germany, and China, which not only greatly saves plating energy, but also creates conditions for the production of thick galvanized and tin steel sheets because of the increased plating current density.
6, non-ferrous metal extraction
Electrolytic metallurgy occupies a large proportion in the hydrometallurgical industry. Non-ferrous metals produced by electrolytic metallurgy include Zn, Cd, Cu, Mn, Co, Ni, Cr, and the like.
The advantages of electrolytic metallurgy are high selectivity, high purity metals, and the recovery of useful metals. Therefore, it can handle low-grade minerals and complex polymetallic ore components, which is beneficial to the comprehensive utilization of resources. In addition, the pollution to the environment is small, and production is easier to continue and automate.
In recent years, coated titanium electrodes have been widely used in the field of electrolytic extraction of metals, and have become the second industrial field in which titanium electrodes are used on a large scale.
7, electrolytic copper foil
With the development of science and technology, the degree of automation is increasing, which has promoted the rapid development of the electronics industry. The application of large integrated circuits has increased the demand for copper foil in the electronics and instrument industry, and the quality requirements for copper foil are also increasing.
According to the thickness, it can be divided into several types such as 105 μm, 70 μm, 35 μm, 18 μm, 12 μm, 9 μm, and 5 μm, and the copper foil of 12 μm or less is generally referred to as an ultra-thin copper foil.
The electrolytic copper foil is a cathode which is partially immersed in a copper sulfate solution and continuously rotated, and is continuously electrolyzed to produce a foil. The international production of copper foil is mainly controlled by Japan, with about 15 domestic production enterprises and a production capacity of around 35,000 tons.
8, sewage treatment
With the rapid development of industry and agriculture and population growth, the amount of sewage discharged by humans has increased dramatically, causing many waters to suffer from different degrees of pollution. Electrochemical treatment of sewage is divided into direct electrolysis and indirect electrolysis.
1) Direct electrolysis means that contaminants are directly oxidized or reduced on the electrode to be removed from the wastewater. Direct electrolysis can be divided into a cathode process and an anode process. The anode process refers to the oxidation of pollutants on the surface of the anode to be converted into less toxic substances or biodegradable substances, and even inorganic substances to reduce the pollution. The cathode process refers to the reduction of pollutants on the surface of the cathode to be removed. It is mainly used for the recovery and dehalogenation of halogenated hydrocarbons and the recovery of heavy metals.
2) Indirect electrolysis refers to the use of electrochemically generated redox species as reactants or catalysts to convert pollutants into less toxic substances. Indirect electrolysis can be divided into reversible processes and irreversible processes. The reversible process refers to the electrochemical regeneration and recycling of redox species during electrolysis; the irreversible process refers to the oxidation of organic matter by substances produced by irreversible electrochemical reactions.
It is applied to printing and dyeing wastewater treatment, landfill leachate treatment, manure sewage treatment, cyanide-containing wastewater treatment, pharmaceutical wastewater treatment, hospital sewage treatment, and organic wastewater treatment.
9, PCB electronic circuit board factory etching waste liquid recycling
Etching is an important process in the production of printed circuit boards. With etching, the waste etching solution contains a large amount of copper ions or other metal ions, which can be recycled by electrolysis. Through this recycling process, enterprises not only increase the economic benefits by recycling metals such as copper, but more importantly, they meet emission standards and resource recycling, and have long-term social benefits.
The waste liquid includes: acid etching waste liquid, alkaline etching waste liquid, low copper containing waste liquid, waste fixing liquid, waste frame material, nickel-containing waste liquid, waste liquid containing gold and palladium, and waste tin-removed water.
Five, electrode use precautions
1. The titanium electrode is black after being oxidized and sintered, and the uncoated surface is blue without electrode performance, and the black side is used for the cathode.
2. Once the titanium electrode substrate is acid-washed, all the subsequent production and processing steps and procedures must be carried out with strict care. When transporting, wear clean gloves to catch the ends or edges of the anode, preferably in the uncoated portion. Any foreign matter is strictly prohibited from being scratched on the surface of the coating.
Note: The titanium matrix itself is not electrically conductive, and its outer layer coated with noble metal oxide coating has electrocatalytic activity, electrical conductivity and oxidation resistance, but its thickness is only about 20 microns. If it is scratched or damaged, it is electrolyzed. During the process, the electrode first corrodes from the damage, which in turn affects the quality and effectiveness of the entire electrode.
3, the electrolyte maintains stability, especially can not contain cyanide ions and fluoride ions, these impurities will seriously corrode the titanium matrix;
4. The electrolyte should be added to the electrolysis tank before adding the filter device. It should not contain metal particles with a diameter greater than 0.1mm to prevent the accumulation of too much cathode and anode short circuit.
5. When electrolytically recovering metals such as copper, nickel, gold, silver, cobalt, etc., the cathode deposits shall not be too thick to prevent the pole pitch from being too small or the metal thorn formation to cause a breakdown of the cathode and cathode.
6, the anode and cathode spacing can be set according to the actual production, generally 5-25mm. Generally speaking, the pole distance assembly increases the voltage drop, but it should not be too small, otherwise the cathode scale generated on the cathode surface is liable to cause short circuit of the pole plate;
7. Avoid using the pole. Once the noble metal oxide coating is used as a cathode, the surface undergoes a reduction reaction, which is easily converted into a simple metal element, and cannot be effectively combined with the titanium base, causing the coating to fall off.
8. It is not advisable to immerse in the solution in the power-off mode for a long time when stopping. It is best to load a small current of about 5A to protect the plates.
9. When shutting down or other maintenance conditions, add diluted acid or clean the surface of the electrode with water, but do not wash with nylon or mechanical substances.
10, the temperature of the electrolyte should not be too high, the ideal temperature of 25-40 ° C, there are conditions to add heat exchangers to maintain the electrode environment.
11. The normal working current density is less than 2000A/m2. If the current is too large, the reaction is too intense and the anode life is shortened.
12. When starting up, add current to the electrolyzer in a step-by-step manner. Do not raise it in one position at a time, as well as when it stops.
13. Keep the anode clean during production and use, and do not contaminate oil or other deposits, so as not to affect the electrolysis effect and electrode life.
14, the anode has life, to ensure the stability of production is more beneficial to extend the life cycle.
Titanium anode for industrial wastewater treatment
Electrolytic oxidation or electrochemistry, in the process of treating water, including industrial water and factory wastewater, the electrode not only plays a role in transmitting current, but also catalyzes the oxidative degradation of organic matter. In this process, since it does not cause pollution, Known as green water treatment. With the development of industry, the discharge of organic wastewater is increasing, especially the high-concentration wastewater discharged from the chemical, food, pesticide and pharmaceutical industries. The color is highly toxic and contains a large amount of bio-degradable components, which seriously pollutes the rivers and lakes. sea. The new technology of electrolytic treatment of water has no need to add chemical agents, the equipment is small in size, covers a small area, does not produce secondary pollution, and has been used to treat wastewater containing organic pollution such as hydrocarbons, alcohols, aldehydes, ethers and phenols. The removal of COD mainly depends on the oxidation reaction on the surface of the anode, and directly oxidizes and degrades the organic matter on the surface of the anode, so that the organic matter in the sewage is directly or indirectly converted into CO2 and water through electrochemical conversion. The anode potential must be higher than the decomposition potential of the organic matter, so the two catalytic reactions of organic oxidation and oxygen evolution are carried out on the anode.
The noble metal oxide coated titanium anode has a high oxygen evolution overpotential, and the anode potential is higher than the decomposition potential of the organic matter. Suitable for sewage treatment. The shape of the anode is available in various forms such as plate type, tube type, and mesh type, and the quality is reliable. The titanium matrix can be reused.

Titanium anode manufacturing process and process:
1, welding
According to the customer’s drawings, some products need to be welded after punching and punching. The welding of titanium materials mainly adopts the method of argon arc welding, and only the same materials can be welded together. Plate and tube welding methods are first fixed by spot welding, then welded, and only spot welding can be performed on the net.

2, sandblasting
A process of spraying onto the surface of a titanium substrate by means of a sand blasting machine by means of compressed aerodynamic forces. The sand material is sprayed onto the substrate for impact grinding to remove impurities, mottling and oxide layers on the surface, and the sand blasting machine roughens the surface of the titanium substrate to improve the effective contact area of ​​the titanium surface and enhance the adhesion between the coating and the surface.
The main point of sand blasting, the pitting and pitting of the spray should be uniform and should not leak.
3. Annealing
Annealing is a metal heat treatment process in which the metal is slowly heated to a certain temperature for a sufficient period of time and then cooled at a suitable rate.
When cutting, some materials are inherently curved or deformed. We can use some methods and tools to make simple corrections, so that they do not overly affect the next work. However, after the local high temperature of the welding and the air pressure of the sandblasting, the deformation of the titanium substrate is obvious.
Place the board (net) on a very thick steel plate. It is required to lay flat and align the corners. You can put another steel plate on the board (net) and diagonally. The lower two steel plates are sufficiently pressed against the intermediate plate (net). After that, it is sent to a furnace having a temperature of about 500 to perform heating correction, and after a certain period of time, it is kept for 2 hours.
4, brushing
The prepared precious metal liquid is evenly brushed on the substrate with a brush, and dried in a drying oven to quickly combine the liquid with the substrate, and also prevent the trace left by the liquid flowing down the substrate. When the first 5 brushes are applied, the liquid can be applied more and can fill the surface of the substrate. The latter needs to brush less liquid to make the liquid brush more uniform, and also cover the front of the brush to make the coating beautiful. Wear a mask when brushing. It is environmentally friendly, ventilated, dust-free, and especially water is not visible. In order to ensure the purity of the liquid, the appearance of the board.
5, baking
After the plates are dried, the furnaces that have reached a certain temperature are kept warm for a certain period of time, so that they are naturally cooled and oxidized. Then go to the next program.
Repeat the procedure: brushing, drying, heating, cooling, cooling.
Brushing program about 14~20 times
