2023-08-17Graphite anode is a graphite plate, block, or rod used as an anode for electrolytic cells in the electrolysis industry. It has characteristics such as high temperature resistance, good conductivity and thermal conductivity, easy machining, good chemical stability, strong acid and alkali corrosion resistance, and low ash content.There are two types of electrolysis industry using graphite anodes, one is aqueous solution electrolysis, and the other is molten salt electrolysis. In the past, the chlor alkali industry, which used to produce caustic soda and chlorine gas by electrolysis of salt water solutions, was the largest user of graphite anodes. However, the chlor alkali industry now widely uses the ion membrane electrolysis process for alkali production, and the graphite anode diaphragm method for alkali production has gradually been phased out. Therefore, the production of graphite anodes is in an extremely shrinking state. Currently, graphite anodes are only used in industries such
2023-08-17Compared with large industries such as machinery, automobiles, electronics and electrical engineering, mining and metallurgy, railways, and transportation, the carbon industry is a small industry, but it occupies an important position and plays an important role in the development of the national economy in China. According to China's first five-year plan, 156 large-scale projects were newly built, of which the carbon industry accounted for two projects. For example, the development of the steel industry cannot be separated from carbon materials and products, especially electric furnaces for smelting alloy steel, which must have graphitized electrodes. Electrolytic aluminum production requires the consumption of 400-450kg of carbon anodes for each ton produced. In addition to ordinary civilian industries, carbon fiber composite materials have a wide range of applications in aviation, aerospace, nuclear energy, military and other fields, such as high specific strength, light weight, an
2023-08-16The basic process of carbon material production includes: pre-treatment (pre crushing, calcination, or drying) of carbon raw materials, crushing, grinding, and screening grading of carbon raw materials, proportioning of carbon raw materials, addition of molten dehydrated binder and kneading, forming of paste after kneading, and roasting of formed green billets. In order to improve the density and strength of products, high-pressure impregnation and secondary roasting cycle densification treatment are carried out on the roasted billets, The graphitization of roasted products involves mechanical processing of carbon and graphite products.Why are the quality indicators of high-power and ultra-high-power graphite electrodes superior to ordinary power graphite electrodes?The current density of graphite electrodes used in high-power and ultra-high-power electric furnaces significantly increases, resulting in the following problems: (1) due to resistance heat and hot airflow, the temperature
2023-06-25The antioxidant treatment process of battery specific graphite includes material preparation, weighing, impregnation solution preparation, impregnation electrode treatment, and drying treatment. After graphite electrode treatment, it can be processed into various specifications of graphite electrode products. The treated graphite electrode is the same as the untreated graphite electrode. Compared with graphite electrodes, it has the characteristics of smooth surface and good conductivity. The mechanical design strength can be increased by 50-60%, the porosity gradually decreases by 10-15%, and the electrode material consumption can be reduced by 20-25%. Electrode consumption can be reduced by 20-25%.The antioxidant treatment of battery specific graphite has the following properties:(1) Preparation material weighing: Weigh the graphite electrode and provide qualified materials to be processed;(2) Preparation and heating of impregnation solution: The composition of impregnation solution
2023-06-25With the gradual breakthrough of mass production and large-scale problems, the industrial application of Graphene is accelerating. Based on the existing technological research and development achievements in China, the first batch of commercial applications may be in the fields of mobile electronic devices, aerospace, and new energy batteries.The bendable screen attracted much attention at the Consumer Electronics Show, becoming the development trend of mobile device displays in the future. The future market of Flexible display is huge, and the future of Graphene as a basic material is full of hope.On the other hand, the commercialization of Graphene for new energy battery is an important field. The college can successfully develop flexible photovoltaic panels with Chinese Graphene nano layers on the surface, which can greatly reduce the cost of manufacturing transparent deformable solar cells, and can be used for small system applications in digital technology equipment such as Night
2023-06-151. As a basic raw material, flake graphite can be processed into ultrafine graphite powder, expanded graphite, nano graphite powder, high-purity graphite powder, etc.2. Flake graphite has good lubricity, high temperature resistance, conductivity, etc. Processed into solid graphite lubricant, widely used in mechanical lubrication.3. The quality of flake graphite depends on its carbon content. By purifying flake graphite, it can be processed into high carbon, medium carbon, and low carbon flake graphite. Each type of graphite has a different carbon content, and the higher the carbon content, the better its industrial use.Flake graphite has strong thermal shock resistance and good corrosion resistance, making it the main carbon material for carbon refractory materials. It has important factors affecting the corrosion resistance and high-temperature working strength of carbon refractory design materials such as magnesia carbon bricks. In the actual production process, carbon refractory ma
