Product Description
Graphite crystals have a hexagonal network planar layered structure composed of carbon elements. The carbon atoms on the layer plane are bonded by strong covalent bonds, while the layers are bonded by van der Waals forces. The bonding is very weak, and the distance between layers is large. Therefore, under appropriate conditions, various chemicals such as acids, alkali metals, and salts can be inserted between graphite layers and combine with carbon atoms to form a new chemical phase - Graphite Intercalation on Compounds (GIC). ). This interlayer compound can decompose rapidly in an instant when heated to an appropriate temperature, producing a large amount of gas, which causes the graphite to expand along the axis into a new worm-like substance, namely expanded graphite. This unexpanded graphite interlayer compound is expandable graphite.

Application
High-energy
battery
material Expandable graphite is used as a battery material to convert the free energy change of the interlayer reaction of expandable graphite into electrical energy. Usually expandable graphite is used as the cathode, lithium is used as the anode or expandable graphite composite silver oxide is used as the cathode, and zinc is used as the anode.
The
sealing
material is made by mixing the raw material high-carbon graphite with concentrated sulfuric acid and concentrated nitric acid for acidification treatment, heat treatment and then pressing and molding. The prepared flexible graphite is a new type of high-performance sealing material and a nanomaterial grown in situ. Compared with traditional sealing materials such as asbestos rubber, it has excellent properties such as good compressibility, resilience, self-adhesiveness, and low density, and can be used for a long time under harsh working conditions such as high temperature and high corrosion. Graphite sheets and sealing components made from it are widely used in machinery, electronics, electric power, shipbuilding, smelting and other industries. Because it has excellent properties such as light weight, electrical conductivity, thermal conductivity, high temperature resistance, acid and alkali corrosion resistance, good resilience, lubricity, plasticity and chemical stability, it is known as the "King of Sealings" in the world.
Application on
coatings
Adding fine particles of expandable graphite to ordinary coatings can produce flame-retardant and anti-static coatings with better effects, and improve their high temperature resistance and fire resistance. A large number of light non-combustible carbon layers formed in the fire can effectively block the radiation of heat to the substrate and effectively protect the substrate. In addition, because graphite is a good electrical conductor, the prepared coating can prevent the accumulation of static charges, and it can be used in petroleum storage tanks to achieve the double effect of fire prevention and anti-static.
