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

How to use expansion graphite

1. Protective useExpansion graphite can be used as protective materials, which can be used to protect metal and other damaged objects, such as circuit boards and steel. Because expansion graphite can expand 10 times, it can effectively block the flames and make these objects from burning with flames.2. InsulationExpansion graphite can also be used as insulation materials, because it has good thermal resistance and can effectively block heat, so it can be used for insulation, such as electronic products. It can also be used for cooling, preventing the loss of heat, thereby playing the role of heat preservation.3. Filtering useExpansion graphite can also be used as filtering materials, because it has adsorption and can be used to adsorb toxic substances, such as pollutants used in water treatment, which can effectively remove pollutants in water. It can also be used for air purification to block the entry of harmful substances.4. Reinforcement useExpansion graphite can also be used as r

Expansion graphite, a new multifunctional insulation material

Expansion graphite is a kind of graphite that can expand and shrink in high temperature environments. This material has very special physical and chemical properties. Graphite is a kind of carbon, and its structure is connected by hexagonal carbon atoms. Generally, graphite can be completely melted, but at high temperature, due to the enhancement of the interaction between carbon atoms, graphite can form more stable stability The structure of the expansion is achieved.1. The development of expansion graphiteThe development of expansion graphite dates back to the 1960s. At that time, scientists discovered that graphite can be deformed regularly within a certain temperature range, and the translucent graphite can remain stable. Subsequently, scientists also found that under certain conditions, graphite at high temperature can be used to create a variety of structures, and these structures can be used to support greater weight and develop the technology of expanding graphite.Second, the

Several physical and chemical indicators that need to be understood when selecting graphite materials

Graphite is an allotrope of elemental carbon, where each carbon atom is surrounded by three other carbon atoms (arranged in a honeycomb like pattern with multiple hexagons) that are covalently bonded to form covalent molecules. Due to its excellent properties, graphite is used to make many materials. Below are several physical and chemical indicators that need to be understood when selecting graphite materials:1. Average particle diameter of the materialThe average particle diameter of a material directly affects its discharge condition. The smaller the average particle size of the material, the more uniform the discharge of the material, the more stable the discharge condition, and the better the surface quality. For forging and die-casting molds with low surface and precision requirements, it is usually recommended to use materials with coarser particles; For electronic molds with high surface and precision requirements, it is recommended to use an average particle size of 4 μ Mater

The densification process of carbon graphite materials

With the continuous expansion of the application field of graphite materials, more and higher requirements have been put forward for it. Therefore, it is necessary to introduce new supplementary process methods in industrial production to facilitate the acquisition of products with special properties that cannot be obtained using ordinary methods. This process method is the compaction of carbon graphite materials.Carbon graphite material is a porous material, with a densification process that involves filling the pores or coating surface of carbon graphite material with different forms of carbon, metal, alloy, or other non-metallic substances. The purpose of densification process is mainly to improve the density, strength, conductivity, thermal conductivity, corrosion resistance, and wear resistance of the product, and sometimes to ensure that the product is impermeable to gases and liquids. However, there is a limit to compaction, and it is not possible to require all the pores in th
