The graphite crucible has good thermal conductivity and high temperature resistance, high temperature in use process, small thermal expansion coefficient. It has a certain anti strain properties. The acid alkali solution, corrosion resistance strong, excellent chemical stability. The graphite crucible, because has more excellent performance, so in casting, metallurgy, machinery, chemical and other industrial sectors, is widely used for smelting alloy tool steel and non-ferrous metal and alloy smelting. And have a good technical and economic effect. The main raw material of graphite crucible is the crystallization of natural graphite, keep the physical and chemical properties of various original natural graphite. Graphite for acid and alkaline solution of stronger corrosion resistance, excellent chemical stability. There are two kinds of domestic…
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…
