Expandable flake graphite flake graphite is widely used in advanced refractory materials and coatings in the metallurgy industry, such as magnesia carbon brick, crucible, etc Stabilizers for initiating explosive materials in the military industry, desulfurizing accelerators in the refining industry, pencil leads in the light industry, carbon brushes in the electrical industry, electrodes in the battery industry, catalysts in the fertilizer industry, etc After in - depth processing, flake graphite can produce graphite emulsion, which is used for lubricants, release agents, wire drawing agents, conductive coatings, etc It can also produce expanded graphite for raw materials of flexible graphite products, such as flexible graphite seals and flexible graphite composite products Flake graphite varieties are classified according to the carbon content: for example, high-purity graphite with a carbon content of 99.99-99.9%; High carbon graphite with a carbon content of 99-94%; Medium carbon graphite with a carbon content of 93-80%; Low carbon graphite with a carbon content of 75-50% When classified by particle size: when the particle size is smaller than W38 fine graphite Properties of flake graphite: flake crystal is complete, flake is thin and toughness is good Excellent physical and chemical properties, good temperature resistance, self lubrication, thermal conductivity, conductivity, thermal shock resistance, corrosion resistance and other properties Main technical indicators of expandable flake graphite: expandable ink is made of high-quality large flake graphite through special chemical treatment. It has good expandability It has the advantages of uniform particle size distribution, uniform and stable expansion. It is mainly used as raw material for flexible graphite products, protective slag for metallurgical industry, flame retardant materials, etc. the main technical indications are shown in the following table. Model: fixed carbon is not less than%, volatilization is not more than%, moisture is not more than%, expansion multiple pH screening amount is% main purpose: KP 3280-99.5 13 2.5 200-400 3-6 ≥ 80 flexible graphite product raw material, protective slag for metallurgical industry Flame retardant materials, etc
