Spherical graphite

Spherical graphite is a graphite product that is made from high-quality, high carbon natural flake graphite and uses advanced processing techniques to modify the surface of the graphite. It produces graphite products with different fineness, resembling elliptical spheroids.Spherical graphite material has good conductivity, high crystallinity, low cost, high theoretical lithium intercalation capacity, low and flat charge discharge potential. It is an important part of the negative electrode material for lithium-ion batteries and a replacement product for negative electrode materials used in foreign lithium-ion battery production. It has excellent conductivity and chemical stability, high charging capacity, long cycle life, and is green and environmentally friendly.The process of processing spherical graphite first involves roughly crushing, dressing, magnetic separation, and other processes in the spherical graphite workshop to form the initial product spherical graphite. Then, it ente

Graphite and cold stack

WatereoledgraphiteModer-Fedreactor with graphite as a slow neutron reactor with graphite as a chronic agent and water as a cooling agent. In the early days of the development of the nuclear industry, graphite and cold stacks were mainly used to produce nuclear weapons installation -钚, 氖, etc. This heap is generally fuel with natural uranium metal components. Uranium 235 in the natural uranium in the pile absorbs neutron reactor in neutron and releases neutron and energy. These neutron parts are used to maintain chain nuclear fissure reactions, and some are absorbed by the uranium 238 in natural uranium and converted into it to converted into it into. 钚 239 and other 素 isotopes. Structural graphite and cold stacks use nuclear pure graphite masonry as a chronic agent and reflective layer. There are two or three thousand horizontal tunnels (horizontal piles) or vertical tunnels (vertical piles) in the graphite masonry. Inserting graphite sleeves in these holes, aluminum alloy crafts pipe

What are the key applications of graphite shells?

With the development of science and technology, graphite slowly turns into selected raw materials for mold production with its excellent physics and organic chemical characteristics. Graphite molds are generally used in various industries. Below I take the old iron to take a look at the key use of graphite mold!1. Rare metal forging and semi -continuous forging for graphite moldIn recent years, countries around the world have been marketing and promoting the situation of fusion metal materials and continuously (or semi -continuous) production and manufacturing bars or pipes. China has gradually selected this method at the level of copper, alloy copper, aluminum, aluminum alloy profiles. Artificial synthetic graphite is a continuous forging or semi -continuous forging as a rare metal. Manufacturing practice has proved that because of the selection of graphite mold shells, it has excellent thermal transmission performance (the heat transfer performance decided to condense the condensate

What aspects will endanger the use period of graphite board

First, the quality of the production and processing of graphite board is the direct cause of the life of the application of its application. Graphite board production and processing must be careful to reach the overall goal of the standard. For example, pre -immersing this level must be well -proportioned, so that its resistance is basically unremittingly consistent, so that the conductivity can be proportioned to prevent the entire production process from occurring in the process of production Some part is complete, but some of the erosion is serious, so that all personnel come out to consume.In the second place, the graphite board must have an excellent office environment, which is the fundamental to prolong life. During the entire production process, reduce the impact and clean up the office environment. It can check the power circuit on time, produce at the best temperature, and reduce the air oxidation of the gas to its air.In the end, high -quality graphite boards are used to im

What are the advantages of high pure graphite?

Simplified graphite is an inorganic non -metallic material. High -pure graphite is a common advantage in processing and manufacturing structure casting molds, exercise of high -pure metal, sintering mold, metal coating, and transmitting electron tube. High pure graphite has corrosion resistance, the substrate is uniform and small, delaying the degree of corrosion of the product. In addition, it also has high thermality. High -content fixed carbon ensures good thermal conductivity, shorten the dissolution time, and significantly reduces energy consumption. In particular, its quality stability, the manufacturing technology and quality assurance system of high -voltage molding methods fully ensure quality stability. If graphite molds and graphite processing products of various shapes and uses can be achieved in the metallurgical industry, graphite with accuracy and roughness can be processed. High -pure graphite is specially designed according to the conditions of rapid heating and fast

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

The application of scales graphite in the coating industry

The functional fillers of scales are mainly used for anti -corrosion coatings, fireproof coatings and conductive coatings.As an anticorrosive material, it has a good rust -proof primer made of charcoal black, talc powder and oil. It has good chemical resistance and solvent corrosion performance. If you add chemical pigments such as zinc yellow to the formula, its rust -proof effect is better. EssenceIt is used as a fireproof filler. It is expandable graphite. It is a graphite intervertebral compound obtained by natural graphite scales. 300 times) suffocating the flame, and at the same time, the expansion material is generated to achieve the effect of isolation of the flame, delay or interrupting the flame spread, and it is not burning, soft, high on the surface, and good coach layer. However, the volume and dosage of the expansion body should be appropriate.
