Graphite Powder is an Important Production Raw Material in the Field of Industrial Production
1. Why is graphite powder an important production raw material in the field of industrial production?
Graphite powder is an important production raw material in the field of industrial production. There are many types of graphite powder, which can meet the needs of various fields of industrial production. There is an important relationship between the use and performance of graphite powder. The performance of graphite powder determines the use and application of graphite powder.
Graphite powder has good lubricating properties, high temperature resistance, electrical conductivity, corrosion resistance, etc. Therefore, graphite powder can be used in various fields of industry. Graphite powder is soft, dark gray; it has a greasy feeling and can contaminate paper.
The hardness is 1~2, and its hardness can increase to 3~5 along the vertical direction with the increase of impurities. The specific gravity is 1.9~2.3. In the absence of oxygen, its melting point is above 3000°C. Graphite powder is one of the most temperature-resistant minerals.
The chemical properties of graphite powder are relatively stable at room temperature, insoluble in water, dilute acid, dilute alkali and organic solvents; react with oxygen at different high temperatures to generate carbon dioxide or carbon monoxide; among halogens, only fluorine can directly react with elemental carbon;
Under heating, graphite powder is easily oxidized by acid; at high temperature, it can also react with many metals to form metal carbides, and metals can be smelted at high temperatures.
Graphite powder uses natural flake graphite as the production raw material, and is processed into various specifications of graphite powder through mechanical crushing. There are many specifications of graphite powder, and the specification of graphite powder is the particle size.
The particle size of graphite powder affects the lubrication performance of graphite powder. The smaller the particle size of graphite powder, the better the lubrication performance of graphite powder. The application of graphite powder in the field of lubrication is ultra-fine graphite powder and nano-graphite powder with small particle size.
Carbon content is also an important factor affecting the conductivity of graphite powder. The higher the carbon content of graphite powder, the better the conductivity of graphite powder. Such graphite powder can be used in the field of conductive material production.
Different production processes of graphite powder produce different graphite powders. The particle size and carbon content of these graphite particles determine the use and performance of graphite powder. Graphite powder can be produced according to its performance, particle size, carbon content, etc. to classify.
Various graphite powders correspond to their respective graphite powder uses. Graphite powder has played an important role in the production fields of industrial lubrication, electrical conductivity, and refractory materials.
