Nuclear and chemical requirements for low-sulfur and high-purity flexible graphite, general nuclear grade flexible graphite 500PPM less sulfur content; the nuclear island part of its requirements are higher. Petrochemical especially fine chemicals, in order to prevent corrosion of the metal surface of graphite seal, flexible graphite Lacey requires inhibition type graphite, generally adding molybdate and other corrosion inhibitors in the flexible graphite. Also in the pipeline leak in order not to stop production Pingdu graphite prices, there with warm, Pressure Seal flexible graphite with injectable fillers. By conventional production process for the preparation of carbon graphite blocks using ordinary carbon production processes can be made of porous carbon and porous graphite block, the difference is the addition of a pore-forming agent, carbon graphite factory in the ingredients, pore forming agent volatile or during firing and graphitization decomposed pores. Commonly used pore formers sodium chloride, sodium fluoride, sawdust, etc., to control the amount of pore-forming agent and the pore forming agent added size, can substantially control porous carbon and porous graphite porosity and pore size.
