The role and use of graphite

Graphite is an allotrope of carbon with various excellent properties, and is therefore widely used in many fields. The following are the main functions and uses of graphite:

The key features of graphite

1. High fever and conduction: In response to the use of raw materials such as graphite with high thermal conductivity, it reduces the time of fusion.2. High temperature resistance: high -temperature resistance has strong impact characteristics, for rapid cold and hot heat, not easy to crack.3. High temperature resistance: high fire resistance, high temperature to 1200 to 1600 ° C.4. Anti -corrosion resistance: strong adhesion to resist melting soup.5. Anti -reflective impact: have a certain anti -reflective impact resistance (when the funds of the melt material are invested, etc.).6. Antioxidant: Graphite is very easy to oxidize at high temperatures in oxidation. Due to the development of oxidation solution, oxidation consumption is less.7. Anti -adhesion: Because graphite is not easy to stick to the soup, the molten soup is soaked and attached with less adhesion.8. There is very little environmental pollution of metal materials: Because there is no bad matter that infiltrate the envi

Graphite physicss

The chemical properties of single -mass carbon at room temperature are relatively stable, insoluble in water, dilute acid, dilute alkali and organic solvents; burning with oxygen at different high temperatures to generate carbon dioxide or carbon dioxide; Below, single -quality carbon is more likely to be oxidized by acid; at high temperature, carbon can also react with many metals to generate metal carbides. Carbon is restored and can smell metal at high temperature.Graphite is soft, black and gray; it is greasy and can contaminate paper. The hardness is 1-2, and the hardness can be increased to 3 to 5 along the vertical direction. The proportion is 1.9 ～ 2.3. The surface area is concentrated at 1-20m2/g. Under the isolation of oxygen conditions, its melting point is above 3000 ° C. It is one of the most temperature-resistant minerals. It can conduct electricity and heat conduction.There is no pure graphite in nature, which often contains impurities such as SIO2, Al2O3, Feo, CAO, P2O

Many new main uses of graphite have been developed and designed

Many new main uses of graphite have long been developed and designed with the development trend of scientific and technological progress. Graphite has many new main uses. High -purity graphite products are used for high -purity metallurgical industry, electronics industry, Chinese nuclear industry and mold processing; general graphite products can be used as a wall -building raw material for mining with aluminum electrolytic grooves, non -metallurgical tunnel furnaces, and non -ferrous metal furnaces. Calcium residual raw materials can be used as carbon increases for ironmaking industry. There are many types of carbon quality raw materials used to seepage nitrogen, including artificial synthesis of graphite, petroleum coke, casting focus, and pure natural graphite.Graphite products are at least within 2000 degrees. This is because carbon must be graphite at a high temperature natural environment of 2000-3300 degrees at a high temperature and natural environment of at least 10 days and

Application of expanded graphite

Graphite products manufacturers introduce the use of graphite block on cement back kiln in detail

The concrete flip kiln is the insulation machinery and equipment that conducts actual operation under negative pressure. The sealing situation on both sides is immediately associated to the production of cement clinkers, quality and energy consumption. In the work of improving and improving kiln heads and kiln tails, it is one of the effective ways to flip the high -yield and energy -saving of the kiln chemical plant. However, because the working conditions on both sides of the flip kiln are extremely high, not only the temperature is high, but also has flipping and shaking together. Therefore, the sealing work of the flip kiln chemical plant is both the key and difficult. Graphite block has the inevitable heat resistance characteristics and excellent authenticity characteristics, which can achieve a good regulation of flip kiln sealing. Therefore, in China, the graphite block has been used as a sealed material in the early 1950s. At this stage, the current stage. The use of use is st
