Graphite powder produced by graphite manufacturers is a widely used industrial material, obtained by crushing, grinding, and screening high-purity graphite through rolling. The key to the type of graphite powder is the particle size, which varies from 50 to 30000 mesh. The more mesh the screen, the finer the particle size, and the higher the price. Previously, our country's technological strength could not be reached, and high-end graphite powder had to rely on imports. However, at present, Chinese manufacturing enterprises have introduced cutting-edge overseas powder mills, which can produce and manufacture fine graphite powder with global particle size, and have been used in many industries both domestically and internationally.
Graphite manufacturers offer various types of graphite powder, including lubricating graphite powder, conductive graphite powder, nanotechnology graphite powder, high-purity graphite powder, and graphite powder screens with a mesh size of 150, 425, 1000, 3000, 5000, 6500, 12500, 15000, etc. The purity of commodities should be above 99.95%, which can be used as: positive and negative electrode materials for lithium ion batteries, conductive agents for Nickel–metal hydride battery and Nickel–cadmium battery, and superconducting conductive powder for other rechargeable batteries Conductive powder for corrosion resistance; Conductive powder for conductive building coatings and conductive printing inks; Graphite sheet for CPU heat pipe heat sink; Architectural coatings and release agents for precision castings
The high-purity graphite ultrafine powder produced by graphite manufacturers includes colloidal graphite powder, with models and specifications including 001, 01, 1, and other specifications of colloidal graphite powder (with a carbon content of 99.99%): -100 mesh, -200 mesh, -325 mesh, -400 mesh, -600 mesh, -800 mesh, -1200 mesh, -2000 mesh, -3000 mesh, -5000 mesh, -8000 mesh, -10000 mesh, -12000 mesh, 10um%, 5um%, 3um%, 2um%, 1um%, and other specifications and technical parameters, It is widely used in the research and development of signature pen, powder metallurgy, lubricating grease, lubricating grease, Dry cell, conductive building paint, moistening building paint, science and technology commission of national defense, scientific research institutes, residential electricity, Aeronautics and strategic power engineering influence weapons and equipment, smoke screen shielding equipment, etc.
Characteristics of graphite powder from graphite manufacturers:
Black Hexagonal crystal family silicon micropowder with lamellar molecular structure, with a metallic texture, a sense of smoothness when touching, high permeability, and no bonding. Density, frictional resistance, hardness, melting point, gradually air oxidation at 450; At room temperature, it is inactive and can be solved only by concentrated sulfuric acid or Potassium chlorate oxidant to obtain graphitic acid or graphite metal oxide without conductive deafness; Digestion and absorption at 420 to form carbon, resulting in matte and conductive hearing loss; Compared to other vapors, only physical adsorption does not reflect, so it has good heat resistance, conductivity, heat transfer, ductility and acid resistance, alkali resistance, solvent corrosion resistance, chemical resistance, and significant lubricity. However, it will lose its lubricity in a vacuum pump environment.
