Currently Pingdu graphite prices, domestic expandable graphite produced using two processes: chemical and electrochemical methods. In addition to two different oxidation step process, the deacidification, washing, dewatering, drying, etc. Other steps. Quality of most manufacturers use chemical products, to achieve GB10698-89 "expandable graphite" standard indicators, to meet the bulk of the production of flexible graphite sheet material requirements and export supply standards. But low volatile (<10%) and production of special requirements of low sulfur content (<2%) of the product more difficult Qingdao graphite prices, production technology, however. 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 chemical Lacey graphite, in order to prevent corrosion of the metal surface sealing, corrosion type requires flexible graphite, generally adding molybdate and other corrosion inhibitors in the flexible graphite. Also in the pipeline leak in order not to stop production, there are strip temperature, Pressure Seal flexible graphite with injectable fillers.
