High purity graphite means that the carbon content of graphite is more than 99.99%. High purity graphite has the advantages of high strength, high density, high purity, good seismic resistance, high temperature resistance, oxidation resistance, small resistance coefficient, corrosion resistance, easy precision machining, etc. It is an ideal inorganic non-metallic material, which is used for processing and manufacturing electric heating elements, Electrical discharge machining graphite, sintering mold, electronic tube anode, etc, Widely used in advanced refractory materials and coatings in the metallurgical industry, stabilizers for military pyrotechnic materials, pencil leads in light industry, carbon brushes in electrical industry, electrodes in battery industry, and catalyst additives in fertilizer industry, high-purity graphite can be further processed to produce high-tech products such as graphite emulsion, graphite sealing materials and composites, graphite products, and graphite wear reducing additives, Becoming an important non-metallic mineral raw material for various industrial sectors.
High purity graphite flakes have complete crystallization, thin and good toughness, excellent physical and chemical properties, good thermal conductivity and temperature resistance, and are widely used in industrial fields such as metallurgy, chemical industry, aerospace, electronics, machinery, nuclear energy, etc. Especially high purity graphite with large specifications and high quality, as an alternative material, has broad application space in high-tech and new technology fields, and has broad application prospects.
There are two purification methods for high-purity graphite, one is wet purification, and the other is pyrometallurgical purification. Wet purification includes flotation method, acid-base method, and hydrofluoric acid method; Fire purification includes chlorination roasting method and high-temperature method.
2023-12-11We all know that graphite has excellent chemical stability. After special processing, graphite also has the characteristics of corrosion resistance, good thermal conductivity, and low permeability. Therefore, it is widely used as heat exchangers, reaction tanks, condensers, combustion towers, absorption towers, coolers, heaters, filters, and pump equipment.
Modeling method is to put a certain total paste in the mold and specifications of the specified mold and specifications, and then press it from the top or below. Sometimes it also increases a certain working pressure on the paste from the left and right positions at the same time, so that the paste is reduced in the mold. The processing of semi -finished products has been checked by model refrigeration. Then accumulate. The molding machine equipment has a column -type pressure machine, which is also a stand -up pressure machine. Modeling method generally only press a piece of goods at a time, and the productivity is relatively low. However, it can be allowed to systematically squeeze and mold.The squeezing molding method is to squeeze the main cylinder of the paste of the paste -loaded manner. The pressure machine should be relatively installed in front of the previous installation and can be effectively disassembled and replaced. The front is equipped with a partition that can be mov2023-02-22Graphite products production and processing in the middle of pressure molding and extrusion molding method
