Immersion graphite

Plug -in graphite, also known as immersive graphite or immersion immersion graphite. Category of non -transparent graphite.Immersion graphitePinyin: jinzishimoEnglish name: ImpregNated GraphiteNote: Use synthetic resin to penetrate graphite to fill its surface and internal pores, and then make the heat treatment to curing the resin and make it. Compared with graphite, mechanical strength is improved and thermal conductivity is unchanged. With the difference in penetrating resin, there are different varieties such as phenolic graphite and bran glycoling graphite.

Graphite lithium battery negative electrode material

From 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

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

Many new main uses of graphite have already been developed and designed

Many new main uses of graphite have long been developed and designed with the development trend of scientific and technological progress. Graphite has many new main uses. High -purity graphite products are used for high -purity metallurgical industry, electronics industry, Chinese nuclear industry and mold processing; general graphite products can be used as a wall -building raw material for mining with aluminum electrolytic grooves, non -metallurgical tunnel furnaces, and non -ferrous metal furnaces. Calcium residual raw materials can be used as carbon increases for ironmaking industry. There are many types of carbon quality raw materials used to seepage nitrogen, including artificial synthesis of graphite, petroleum coke, casting focus, and pure natural graphite.Graphite products are at least within 2000 degrees. This is because carbon must be graphite at a high temperature natural environment of 2000-3300 degrees at a high temperature and natural environment of at least 10 days and

Silicon fossil system

Chemical gas deposition (CVD) method) methodSilicon and carbon -containing gases have a heat decomposition through high -temperature graphite matrix, and SIC is deposited on the surface of the graphite matrix. The raw materials are trichloronetas (CH3SIC3), silicon chloride, hydrogen, silicon steam, etc. The deposition temperature range is wide, from 1175 ° C to 1775 ° C. The SIC layer generated by this method is very dense, the thickness is uniform, and the general thickness is about 0.1 to 0.3mm. However, the combination of SIC and graphite matrix is a combination of pure machinery, and the combination force is weak. When the temperature changes, the SIC layer is prone to cracking and peeling.Chemical Qi Evidence Method (CVR)The raw materials are coke powder and excessive quartz sand or non -fixed silicon powder. Chemical reactions occur when heated to 2000 ° C to generate SIO vapor. SIO steam and carbon -based reactions generate SIC. There is no obvious interface between SIC layers

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
