Classification of Natural Flake Graphite:
1. According to the fixed carbon content, flake graphite can be divided into high purity graphite, high Carbon Graphite, medium carbon graphite and low carbon graphite.High purity graphite (fixed carbon content greater than or equal to 99.9%) is mainly used in flexible graphite sealing materials, nuclear graphite, instead of platinum crucible for chemical reagent melting and lubricant base material;High carbon graphite (fixed carbon content 94.0% - 99.9%) is mainly used in refractories, lubricant base materials, brush raw materials, electric carbon products, battery raw materials, pencil raw materials, fillers and coatings;Medium carbon graphite (fixed carbon content 80% - 94%) is mainly used in crucibles, refractories, casting materials, casting coatings, pencil raw materials, battery raw materials and dyes, etc;Low carbon graphite (fixed carbon content 50.0% ~ 80.0%) is mainly used in casting coatings. - Flake graphite is classified according to particle size: when the particle size is less than 38 μ m, it is called micro powder graphite.
Production Technology :High speed pulverizer, Raymond pulverizer, air flow pulverizer and other advanced grinding equipment are used for micro powder graphite. Application area :It is mainly used in the research and development of power, powder metallurgy, lubricating oil, grease, dry battery, conductive coating, lubricating coating, science and Technology Commission for national defense, scientific research of scientific research institutions, civil nuclear power, aerospace and strategic power interference weapons, smoke shielding weapons, etc.
