Graphite

Introduction

Graphite powder has good chemical stability. Specially processed graphite powder, which has the characteristics of corrosion resistance, good thermal conductivity and low permeability, is widely used in the manufacture of heat exchangers, reaction tanks, condensers, combustion towers, absorption towers, coolers, heaters, filtration , pump equipment. Widely used in petrochemical, hydrometallurgy, acid and alkali production, synthetic fiber, paper and other industrial sectors, can save a lot of metal materials.

The preparation process of ultrafine graphite powder

The natural flake graphite and the raw coke are fed into the crushing chamber by the compressed air through the feeding ejector, and are distributed in the nozzle around the pulverizing chamber, and the ultra-high-speed airflow is sprayed to the pulverizing chamber, so that the coke powder collides with each other at high speed and rubs into a fine powder, with a fine powder. The gas stream is discharged into the classification chamber by the outlet pipe, the coarser particles are separated, and the powder is again pulverized by the return pipe, and the remaining fine powder is collected by a cyclone separator and a bag collector. Ultrafine graphite powder was produced.
Ultra-fine graphite powder is widely used in conductive materials, wear-resistant lubricant batteries, atomic energy industry and defense industry, color picture tube and other fields due to its stable nature. Ultrafine graphite powder can be composited with metal to form metal-based graphite composite conductive material for civilian use, superfine graphite powder is used as lubricant in machinery industry, ultrafine graphite powder is used in color picture tube field for color picture tube made of ultra-fine graphite Graphite emulsion, used as a neutron moderator and protective material in atomic reactors in the atomic energy industry and the defense industry.
