Flexible graphite sheet is wildly used in all kinds of industry field. Flexible graphite roll uses: composite panels, cylinder head gaskets, packing, and so made manufacturing gaskets, sealing elements such as static gauge, mold, flange gasket. Attached to a variety of metal surfaces, improving sealing performance. Flexible graphite sheet / plate, after high purity natural flake graphite by chemical and heat treatment, made of molded rolling, without any binder. In the harsh working conditions still has excellent sealing performance, long life, low maintenance costs. Character and Appearance: black with metallic luster, high dispersion, never bonded graphite powder. Touch greasy feel can heat and good thermal stability, rich conductivity, thermal conductivity, chemical stability, acid and alkali plasticity and organic solvents, corrosion,…
1.carbon/carbon composites, refers to in carbon fiber (or graphite) and its fabric as the reinforced material, carbon (or graphite) as matrix, through processing and handling all the carbon composite material made of carbide. Carbon/carbon composite material is carbon fiber reinforced carbon composites, light quality, good erosion resistance, good thermal shock, high damage tolerance, high temperature and high strength, can be designed as a prominent feature, is used in aviation, spaceflight, circuit level and the production of solar energy silicon, high temperature furnace and other applications. 2. carbon - carbon composite material performance characteristics (1) physical properties: C/C composites at high temperature after heat treatment, the chemical composition of carbon element is higher than 99%, low density, with strong affinity, high…
High purity graphite is refers to the carbon content is more than 99. 99% which is high strength, high density, high purity, high chemical stability, compact structure, high temperature resistance and high conductive rate,also has a good wear resistance. High purity graphite is widely used in metallurgy, chemical industry, aerospace, Electronics, Mechanics, Nuclear power industry etc. Graphite purification method is mainly divided into two categories,one is the wet purification, including flotation, acid-alkali, hydrofluoric acid.The other is the fire purification method, including chlorination roasting method and high temperature method.In addition,with petroleum coke as raw materials to produce high grade fine particles of high purity graphite is also widely used. The production process is: Raw material→calcinations→crocus→ingredients→mix and knead→fine powder→molding→baking→dipping→graphitization. Under the 2000~2800℃…
