Both micropowder graphite and flake graphite are crushed and processed from natural flake graphite: flake graphite is the product of primary crushing and pressing of natural graphite, while micropowder graphite is the product of deep crushing of natural graphite. The most important difference between the two is the particle size. The coarser particle size is flake graphite, and the finer particle size is micropowder graphite. Classified according to the level of carbon content: C%>99.9% is high-purity graphite; 94%<C%<99% is high-carbon graphite; 80%<C%<94% is medium-carbon graphite; 50%<C%<80% is low-carbon graphite.
Flake graphite has complete crystallization, thin flakes and good toughness, excellent physical and chemical properties, and has good temperature resistance, self-lubrication, conductivity, thermal shock resistance, corrosion resistance, etc.
Micro-powder graphite Our company adopts high-speed pulverizer, Raymond mill, jet mill and other grinding equipment to produce various types of micro-powder graphite series products.
Flake graphite and fine powder graphite are widely used in advanced refractory materials and coatings in the metallurgical industry, stabilizers for pyrotechnic materials in the military industry, pencil leads in the light industry, carbon brushes in the electrical industry, electrodes in the battery industry, catalysts and additives in the fertilizer industry, etc. After deep processing, flake graphite can produce graphite milk, graphite sealing materials and composite materials, fillers or modifiers for various composite materials of plastics, graphite additives to reduce wear, etc., becoming an important non-metallic mineral raw material in various industrial sectors.
Typical application: Flake graphite is used on the surface of copper smelting furnace to isolate and resist oxidation, prevent oxidation of molten copper water, and ensure the purity of copper water. Parameters for this application:
Particle size:
Min 90% retained on 50 mesh ASTM shieve
Packing:
In paper sacks of 20-30 kg. No metal seals on the sacks allowed
Other requirements:
The graphite has to be free flowing, not dusting and harmful impurities must not dissolve from the product into the melt.
Composition:
C min.99.5%
Si max. 1000 ppm
Al max.500 ppm
Fe max. 400 ppm
S max. 300 ppm
Ca max. 100 ppm
Mg max. 50 ppm
Cr max. 5 ppm
Moisture max.0.2%
Ash max.0.5%
