6. Product usage background and introduction:
     The principle of producing sodium hypochlorite by the electrode method is to use diaphragm-free electrolysis to generate sodium hypochlorite through a homogeneous secondary chemical reaction. The reaction principle of the anode is to electrolyze sodium chloride (tablet form) put into the swimming pool. During the electrolysis process, sodium hypochlorite is formed. The most suitable salt concentration is 3%-5%. The electrodes used in sodium hypochlorite generators include plate electrodes and tubular electrodes.
     The anode material can be coated titanium electrode. The mixed oxide coated titanium anode has a long service life. The overpotential of this coated titanium anode is also relatively low, the chlorine evolution current efficiency is high, and the energy saving effect is good.
     Sodium hypochlorite generators are divided into two categories: sanitary disinfection and environmental protection. The titanium anodes currently produced by our company are used in sanitary disinfection: swimming pool disinfection, tableware disinfection, hygienic food disinfection and other sodium hypochlorite generators that are directly related to human health. In terms of environmental protection, there are mainly sodium hypochlorite generators for hospital sewage treatment and various industrial wastewater treatment. The specifications, shape and coating performance requirements of titanium anodes can be processed according to customer needs.
The water flows through the electronic processor and receives electronic field treatment, which can prevent dirt deposition, destroy old dirt, kill Bacillus subtilis, Pseudomonas aeruginosa, cholera bacteria, harmful bacteria, dysentery bacteria, salmonella, and Escherichia coli, and has broad-spectrum sterilization capabilities.

     Precious metal oxide-coated titanium electrodes can disinfect swimming pool water and can also be used to disinfect domestic water in water tanks in high-rise buildings.

4) The titanium anode adopts new materials and structures, which greatly reduces its weight and facilitates daily operation.
5) Long service life, and the substrate can be reused, saving costs
6) The oxygen evolution overpotential is about 0.5V lower than that of the lead alloy insoluble anode, which reduces the cell voltage and energy consumption.

6. Product usage background and introduction:
In the field of electroplating applications, the required coating metal is dissolved in the electrolyte, the plated metal substrate serves as the negative electrode, and the anode serves as the positive electrode, forming a complete current transmission cycle. A chemical reaction that occurs simultaneously with electroplating in the electroplating bath is the evolution of oxygen on the anode surface.
     Compared to non-inert anodes such as graphite, the advantage of titanium anodes is that they maintain a stable positive-to-negative distance (distance between electrodes) over their service life. Graphite anodes will gradually dissolve during use, causing the distance between electrodes to increase, while inert titanium anodes can ensure stable voltage and product quality. Due to the catalytic properties of the platinum group elements, the exchange current density on the electrode surface is large and the oxygen precipitation overpotential is low. A special process is used to form a fine-structured oxide film on the titanium surface, which achieves maximum results per unit electrode area. active surface area, so it is particularly suitable for high-speed and high-current density electroplating production.
    In addition to titanium anodes and graphite, lead anodes can also be used in this field. However, when lead anodes dissolve, their reactants can negatively impact the environment. These problems can be avoided by using titanium anodes. The oxygen-evolving titanium anode has a lower operating voltage, which can also save energy.
    Another advantage of using titanium anodes is that the titanium matrix can be reused. When the titanium anode coating reaches the end of its useful life

    Anodized aluminum foil is a material commonly used in the lithographic printing industry. It works on the same principle as the electroplating process. A very thin layer of metal is coated on the surface of the base metal. By placing aluminum in an anode state, the surface of the aluminum is oxidized. After the anodizing (oxidation) process of aluminum, the surface of the aluminum can bond better with the photosensitive coatings used in the lithographic printing industry.
     In the electroplated metal industry, anodes are used to plate a variety of substrates, from small batches of jewelry to continuous large-scale production of electroplated steel sheets. The company's anode products help realize the diversification of electroplating substrates, and its diversification is also reflected in the diversification of the company's anode products.

7. Product usage background and introduction:
When people use electric water heaters, they sometimes experience water leakage, electricity leakage, and reduced water output. This phenomenon is most likely caused by corrosion and perforation of the inner tank and heating tubes caused by failure to replace the magnesium rods in time after consumption. Generally speaking, the magnesium rods of electric water heaters must be replaced every two years. However, there are also products from manufacturers with poor manufacturing standards that cannot meet the design life. They corrode quickly and are even consumed in less than a year. They have short lifespans and are frequently replaced. , increased use costs, etc. are many disadvantages of magnesium rod anti-corrosion technology. The life of the water heater liner is the most prominent problem plaguing the water heater industry. Once the water heater liner leaks, it means the life of the water heater is terminated and may even cause economic losses to the user. The main cause of water heater leakage is the corrosion of anions in tap water. The water quality varies greatly across China. It is difficult to find a liner protection technology that is effective for all water qualities.
When current passes through the electrode, the Cl_ in the tap water moves toward the metal oxide-coated titanium electrode as the anode, and is enriched near the anode. Near the water heater liner as the cathode, its Cl_ concentration will be greatly reduced, slowing down the water heater's inner tank. The corrosion rate of the gallbladder greatly extends the service life of the water heater liner and also reduces the consumption of magnesium rods.
