Another side of the flexible graphite sealing material development, is the development of flexible graphite lower indices. Japanese endemic lowest flexible graphite carbon content of 90% graphite Qingdao, reducing the cost and selling price. Indeed, for some devices, such as farm machinery, chemical machinery, and other extensive Pingdu graphite factory, there is no need to use high-grade flexible graphite. Low-grade flexible graphite sealing performance is better than asbestos and can meet the technical requirements, and costs are low, so low-end products in the market has a strong competitive edge sweep graphite, thus promoting the development of the industry. Chemical vapor deposition process of producing graphite blocks carbon felt as a substrate, using a chemical vapor deposition process to produce charcoal filter plates (porous carbon), porous carbon plate this legal system, the tensile strength of 43MPa, compressive strength of 105-- 130MPa, a porosity of 20 to 30%, the mechanical strength than. above conventional carbon production processes pore pore former material prepared much carbon graphite sell, you can filter> particles 5pm, you can use the following in 5001 , acid and alkali resistance, corrosion resistance and thermal fluoride solution for Ni-base superalloys chemical separation of tantalum and niobium. _ Sea Dragon Lacey Graphite Carbon Co.
