Product Description

Amorphous graphite, also known as microcrystalline graphite, is mainly found in provinces such as Inner Mongolia, Shanxi, andan. Amorphous graphite is of high quality, with high fixed carbon content, low harmful impurities, and extremely low sulfur and iron content. It enjoys high reputation in the domestic and international graphite market and is known as the "Golden Sand".
In the foundry industry, coating the surface of solids with graphite can form a smooth film that adheres firmly, which is a example of graphite's excellent coating performance. It serves as an excellent release agent in casting. The commonly used graphite powders in casting are crystalline graphite powder ( graphite powder) or amorphous graphite powder (soil-like graphite powder, also known as microcrystalline graphite powder, black lead powder). To day, many small rural factories that produce thin-walled small parts by hand do not add coal powder to their sand mixtures, but instead brush soil-like graphite onto the surface of wet sand molds with soft brushes. The surface of the castings poured is quite smooth. Although the graphite powder does not form bright carbon when molten iron is poured, the wetting angle of the graphite on the molten iron is much greater than 90 degrees, which means the sand mold not wetted by the molten iron. Moreover, the surface pores are blocked by the soil-like graphite powder, preventing the molten iron from penetrating and drilling the sand particles, which can prevent the casting from sticking to the sand and improve the surface finish of the casting. Graphite powder has good lubricating properties, improves the compacting flowability of the sand mix, reduces its permeability, decreases the resistance to ejection, and improves the molding performance of the sand mix
