Amorphous Graphite Powder, Packaging Type : gray black

APPLICATION：
Actually used mainly in the foundry industry, the graphite powder coating on the surface of the solid, can form a smooth film adhesion strong, this is the appearance of graphite good coating performance, it is a good casting remover casting commonly used graphite powder have crystalline graphite powder (flake graphite powder) or aphanitic graphite powder (earthy graphite powder, also known as microcrystalline toner, black lead powder).So far there are a lot of manual production of thin wall small villages and towns small factory without pulverized coal in the sand, but with a soft brush brush earthy graphite powder to the surface of green sand mold, pouring out of the casting surface is quite smooth.Although when pouring molten iron graphite powder does not form the light carbon, but the graphite iron liquid wetting Angle is greater than 90 °, the sand mould is not iron liquid wetting.And porosity on the surface of the stone toner jam, iron liquid penetration and not easily across the sand, can prevent adhering sand castings and improve casting surface is bright and clean degree.Graphite powder has the good lubrication, raise the tight liquidity of molding sand, permeability is decreased, sample ejection resistance reduction, improve the performance of draw on the sand.
The graphite micro powder specifications：
100 mesh, 200 mesh, 325 mesh, 800 mesh, 1200 mesh, 2000 mesh, 4000 mesh, 5000 mesh, 8000 mesh, 10000 mesh, 12000 mesh such as various models, anticorrosive coatings, rubber, oil is special, special glass fiber reinforced plastic, printing ink, dry cells, decreased sexual battery is special, lubrication coatings, powder metallurgy graphite etc.
