    Do you know the difference between carbon felt purification and graphite felt?

    Carbon felt is a felt made of carbon fiber, which has a wide absorption spectrum and a large capacity. Graphite felt can be made by high temperature graphitization. Graphite felt is mainly used as thermal insulation material for monocrystalline silicon smelting furnace.Carbon felt purification can be used as adsorption purification material, as insulation material for vacuum furnace and inert gas furnace. In addition, carbon fiber materials have advantages in fields that have strict requirements on strength, stiffness, weight, fatigue characteristics, etc., and in occasions that require high temperature and high chemical stability. The carbon content is about 90%, and the service temperature is about 1000 degrees Celsius.The main use of graphite felt is as insulation material for monocrystalline silicon smelting furnace. It can be used as a filter material for high-purity corrosive chemicals in the chemical industry. Under the condition of non-oxidizing atmosphere, the service tempera

    Application of graphite cathode carbon block

    Carbon blocks made from high-quality anthracite, coke, graphite, etc. Used as a cathode for aluminum electrolysis cells. It is built at the bottom of the electrolytic cell, also known as the bottom carbon block. The characteristic cathode carbon block plays a dual role in conducting electricity and forming the inner lining of the electrolytic cell. Aluminum electrolysis production requires cathode carbon blocks to have high temperature resistance. The characteristics of resistance to molten salt erosion and conductivity, good thermal conductivity, high mechanical strength, good thermal shock resistance, and strong sodium corrosion resistance are conducive to energy conservation and improved cell life in aluminum electrolysis production.Graphite cathode is a conductive material used for the cathode of aluminum electrolysis cells, representing the development direction of the electrolytic aluminum industry. With the technological progress and development of the electrolytic aluminum ind

    Graphite anode usage

    In an electrolytic cell, the current flowing into the electrolyte from this point is called a graphite anode plate. In the electrolysis industry, the anode is generally made into a plate shape, so it is called a graphite anode plate. It is widely used in ferries, wastewater treatment, industrial anti-corrosion equipment, or as a special material.Compared with other materials, graphite anode plates have advantages such as high temperature resistance, good conductivity and thermal conductivity, easy mechanical processing, good chemical stability, acid and alkali corrosion resistance, and low ash content; Used for electrolyzing aqueous solutions, producing chlorine, caustic soda, and electrolyzing salt solutions to produce alkali; For example, graphite anode plates can be used as conductive anodes for electrolysis of salt solution to produce caustic soda. Graphite anode plates can be used as conductive anodes in the electroplating industry, making them an ideal material for various elect

    Graphite material properties

    Graphite materials are mainly composed of polycrystalline graphite and belong to inorganic non-metallic materials. However, they are called semi metals due to their excellent thermal and electrical conductivity. Graphite has higher thermal and electrical conductivity than certain metals, and also has a much lower coefficient of thermal expansion, high melting point, and chemical stability than metals. This makes it of great value in engineering applications. Graphite has good corrosion resistance and does not react with any organic compoundsGraphite is another high-temperature resistant material that does not melt at high temperatures. It also has good thermal shock resistance and excellent self-lubricating propertiesThe disadvantage of graphite is its poor seismic performance. It begins to oxidize at 500 ℃ in the atmosphere, and the oxidation rate increases with the increase of temperature

    electronic effect

    The load migration rate of graphene at room temperature is about 15000cm2/(v · s). This value exceeds 10 times the silicon material. More than twice. Under certain conditions such as low temperature, the load migration rate of graphene can even be as high as 250000cm2/(v · s). Unlike many materials, the electronic migration rate of graphene is less affected by temperature changes. At any temperature between 50 and 500K, the electronic migration rate of a single laye

    graphite expansion graphite environmental materials

    The effect of expanding graphite on water pollution has a large number of research results. In terms of governing oil and organic pollution in the control of water bodies, expansion graphite is far more effective and economical than ordinary activated carbon now. But expansion graphite is inconvenient to transport and needs to be prepared at the application site. The preparation, use, recycling, and regeneration of expansion graphite environmental protection materia
