Carbon / the process of graphite materials impregnated with PTFE impregnated with phenolic resin, epoxy resin, furan resin and metal process similar, but due to using impregnated materials of different process conditions is also slightly different. The process is as follows: Graphite billet cleaning, canning, vacuum, input PTFE dispersion, pressure relief, remove the blank, drying, sintering, cooling furnace. PTFE impregnated carbon / graphite materials development began in the early 1950s. At that time, British Morgan carbon company, Union Carbide Corporation figure, France Roland carbon company, SGL company, the former Soviet Union Moscow electric pole factory has both the Teflon impregnated carbon graphite materials technology research and development and the technical application in motor with brush, mechanical sealed with parts and…
The graphite plates are in the shape of plates , according to the use requirements and exact use situation , it can be divided by the raw material , vibracation graphite plates , molded graphite plate and isostatic graphite plates , with different use life and prices , the application of the graphite plates as below: 1) refractory materials: in the smelting industry, with graphite manufacturing graphite crucible, ingot protective agent, smelting furnace lining magnesia carbon brick. 2) a conductive material: in the electrical equipment industry, the widespread adoption of graphite electrode, carbon brush, flashlight, carbon nanotubes and TV picture tube coating. 3) wear resistant materials and lubricants: in many mechanical equipment, using graphite as wear-resistant and lubricating materials, can…
Carbon carbon composite material are carbon matrix composite material reinforced by carbon fiber and its fabric. With the advantages such as low density (<2.0g/cm3), high strength, high modulus, high thermal conductivity, low expansion coefficient, good friction performance, good thermal shock resistance and high size stability.It is a few alternative materials in above 1650℃ application now , the theoretical maximum temperature as high as 2600℃. So it is considered to be one of the most promising high temperature materials. Carbon carbon composite consist of three different components, namely, resin carbon, carbon fiber and pyrolytic carbon. Because it is almost entirely composed of elemental carbon, it can withstand extremely high temperatures and a great heating rate. By means of reinforcing the orientation…
