2023-08-09Carbon graphite material is a granular structure material made from various raw materials with different particle sizes, through the addition of binders, kneading, forming, roasting, and graphitization. Therefore, the performance of materials is not only related to the particle size, type and dosage of binders, as well as process control and operation during the production process, but also to the type and performance of the raw materials themselves.There are many solid raw materials used in the production of carbon graphite materials, such as ordinary petroleum coke, needle shaped petroleum coke, asphalt coke, artificial graphite, natural graphite, carbon black, anthracite, metallurgical coke, charcoal, sugar charcoal, bone charcoal, and so on; For electrochar products, there are also metal powders such as copper, silver, tin, lead, and artificial resins; For mechanical carbon and furnace lining materials, as well as silicon carbide, carbon dioxide, and patterned clay; For carbon fib
2023-08-08(1) The storage site for carbon raw materials must be a cement floor, and the mixing of external impurities should be minimized when storing raw materials.(2) During the storage of raw materials, it is strictly prohibited to mix dust, sediment, and other impurities. It is best to store low ash materials in storage, and urgently needed raw materials should be kept in stock. For spare raw materials, if there is no warehouse for storage, they can also be stored outdoors, but management must be strengthened and appropriate measures must be taken.(3) During the storage period, carbon raw materials should be prevented from mixing with each other, especially to prevent more ash raw materials from mixing with less ash raw materials. If the raw materials are mixed, they should be downgraded for use. For the same type of raw materials, if the quality inspection results differ significantly, they should be stacked separately.(4) To prevent rain and snow from soaking in raw materials, it is neces
2023-08-08From the lead core of a pencil to the nozzle of a solid fuel rocket; Although the dark and unremarkable mass, this material composed solely of carbon atoms has quietly entered various fields of industrial production and become an indispensable part of people's lives, which is graphite. If you learned that it is still one of the core raw materials for lithium batteries and is at the forefront of the new energy electric vehicle industry today, would you feel that the investment prospects of a graphite processing enterprise are different?Graphite has good electrical conductivity and is often used to make negative electrodes for lithium batteries. Whether it is flake graphite concentrate that can be used as a solid lubricant, or spherical graphite that can more effectively encapsulate particles due to its rounded shape, it is one of the core raw materials for lithium-ion batteries. New energy vehicles are equipped with lithium batteries, so their application prospects are quite broad in d
2023-08-08Carbon rods are made from carbon or graphite materials as the substrate. Carbon rods can be used as electrodes for arc discharge in various electrical equipment that generate thermal or light energy. During arc discharge, high temperature and strong luminous intensity are generated.Carbon rods can be divided into film projection carbon rods, high color temperature photography carbon rods, ultraviolet linear and sunlight type carbon rods, photographic plate making carbon rods, carbon arc air gouging carbon rods, precision casting carbon rods, electrolytic carbon rods, arc lighting carbon rods, spectral carbon rods, battery carbon rods, and welding carbon rods according to their purposes.Arc lighting carbon rods are used in searchlights, as well as in strong arc lamps for film projection, photography, plate making, and ultraviolet light sources. Carbon arc air gouging carbon rods are used for arc cutting of metal materials, drilling, eliminating casting risers and other defects. Spectra
2023-08-07Impermeable graphite is an ideal material with good corrosion resistance and thermal conductivity in chemical production. It can be used to make heat exchangers, reaction tanks, absorption towers, gas combustion towers, hydrochloric acid synthesis furnaces, graphite centrifugal pumps, jet pumps, and various pipelines and joints. Impermeable graphite is divided into three categories:1. Impregnated impermeable graphite products - This is made by impregnating the graphite matrix. Impregnating agents not only reduce the porosity of graphite, but also increase the compressive strength and tensile strength of graphite materials by 1-2.5 times and 4-5 times respectively; Increase bending strength by 2-3 times; Increase the impact strength by 2-2.5 times. Commonly used impregnating agents include phenolic resin, furfural ketone resin, furfural alcohol resin, organic silicon resin, water glass, paraffin, divinylbenzene, asphalt, etc.2. Pressed impermeable graphite product - is a material made
