By conventional production process of producing graphite carbon blocks using ordinary carbon production process can be made porous carbon and porous graphite block, except that the pore forming agent is added in the ingredients, a pore forming agent to generate pores volatilization or decomposition during firing and graphitization. Conventional graphite pore formers sodium chloride, sodium fluoride, sawdust, etc., is added to control particle size Lacey graphite addition amount of the pore forming agent and a pore forming agent, can be substantially controlled porosity of the porous carbon and porous graphite and aperture . Nuclear and chemical requirements for low-sulfur and high-purity graphite flexible, general nuclear grade flexible graphite sulfur content below 500PPM; nuclear island part of its requirements are higher. Petrochemical especially fine chemicals, in order to prevent corrosion of the metal surface sealing graphite prices, requiring corrosion-type flexible graphite is generally added molybdate inhibitor such as flexible graphite. There are leaks in the pipeline in order not to stop production, there with warm, Pressure Seal flexible graphite with injectable fillers.
