Graphite

Graphite is a carbon element crystalline mineral, and its crystalline grid is hexagonal layered structure. The distance between each network layer is 3.40å, and the distance between the carbon atom in the same network layer is 1.42å. It belongs to the hexagonal crystal system, with a complete layer -like lapse. The molecular keys are mainly attractive to the molecular keys, so its natural floatingability is very good. Graphite and diamond, carbon 60, and carbon nanotubes are both the monomer of carbon, and they are similar aliens.Six carbon atoms form a rumor-shaped ring on the same plane, stretching into a layer structure. Here the key length of the C-C key is 142pm, which is exactly the length of the keys of the atomic crystal. Therefore It is an atomic crystal. There is a P orbit left in the carbon atoms of the same plane, which overlap each other. Electronics is more free, which is equivalent to free electronics in metal, so graphite can conduct heat and conductivity, which is ex

The Function and Conditions of Adhesive

Carbon graphite material is a powder structure material similar to refractory materials and concrete. Except for non-ferrous brushes and mechanical metal graphite products, which are formed as a whole with a certain strength by phase transformation of metal powder at sintering temperature, the powder particles of typical carbon graphite materials cannot spontaneously bond together even at high temperatures. In order for them to bond into a whole with a certain shape and strength, a certain amount of substance that can bond carbon powder particles or fibrous fine substances into a whole must be added, and this substance is called a binder.The conditions that the adhesive should meet:1) The adhesive should be able to mix with the main material to form a plastic substance.2) The binder becomes a viscous liquid within an appropriate temperature range. And it can have good adhesion and adsorption with the particles of the main material, and has a large adsorption force.3) The binder should

How to Use Expanded Graphite

1. Protective purposesExpanded graphite can be used as a protective material to protect metals and other easily damaged objects, such as circuit boards and steel. Due to the fact that expanded graphite can expand up to 10 times, it can effectively block flames and prevent these objects from being burned by flames.2. Insulation purposeExpanded graphite can also be used as insulation material because it has good thermal resistance performance and can effectively block heat, so it can be used for insulation, such as electronic products. It can also be used for cooling, preventing heat loss, and thus providing insulation.3. Filtering purposeExpanded graphite can also be used as a filter material because it has adsorption properties and can be used to adsorb toxic substances, such as pollutants in water treatment, effectively removing pollutants from water. It can also be used for air purification to block the entry of harmful substances.4. Reinforcement purposeExpanded graphite can also b

What are the factors that affect scales graphite quality?

The quality of scales graphite determines the product quality of the processed scale graphite powder. The scales graphite resources are natural graphite of the light crystal, which is formed by deteriorating quality under the action of long -term geology. The scales graphite crystals are scales -shaped. The scale of the scales of scales graphite and the amount of carbon content is the key factor affecting the quality of scales. The following editors will take you to understand:As the basic processing raw materials of various graphite powder products, the quality of scales graphite is an important condition. According to scales graphite quality, various parameters, etc., scales can be processed into graphite products such as scales graphite, ultra -fine graphite powder, high pure graphite, nanim graphite, colloid graphite and other graphite products. The scale size of the scales graphite determines the lubrication performance of processed. The larger the scale graphite size, the better

What is the heating principle of vacuum furnace heating graphite tubes?

The principle is to quantitatively inject the sample into a graphite tube using a sampler, and use the graphite tube as a resistance heating element. After being energized, the sample quickly heats up to achieve atomization. The heating power supply, maintenance gas control system, and graphite tube furnace are composed. An external power supply is added to both ends of the graphite tube to supply energy to the atomizer. The current flows through the graphite tube to generate a temperature of up to 3000 ℃, causing the measured element in the graphite tube to become ground state atomic vapor. The maintenance gas control system is used to control the instrument startup of maintenance gas, maintain the flow of Ar gas, and cut off the Ar gas flow after the air combustion is completed. The Ar gas in the external gas path flows along the outer wall of the graphite tube to maintain it from being burned, while the Ar gas in the internal path flows from both ends of the tube to the center of t
