Improve the performance of consumer electronics. The product is uniformly dissipated while providing heat isolation in terms of thickness. The molecular structure diagram of the thermal graphite sheet is as follows:The unique combination of heat dissipation and thermal insulation performance of graphite heat conductive solutions allows heat -conducting graphite to become an outstanding material option for heat management solutions. The thermal graphite plane has the ultra-high thermal conductivity within the range of 150-1500 W/m-K.The chemical composition of Thermal Flexible Graphite Sheet is mainly a single carbon (C) element. It is a natural element mineral. The film polymer compound can obtain a graphized thin film under high temperature and high pressure because the carbon element is non -metal.

Do you know the development history of graphite?

Graphite occupies an important position in the industry, and because of its good performance, graphite is widely used in many industries, and its use effect is good, so it is loved by users. Some basic knowledge of graphite must be known to everyone. The following is the development history of graphite. Presumably very few people know this. So today, let us take a closer look. The following is the introduction made by graphite manufacturers.Graphite is a kind of carbide accidentally discovered in the laboratory by Acheson of the United States in 1891 when he was conducting molten diamond experiments. At that time, it was mistaken for a mixture of diamonds, so it was named emery. The industrial method of smelting graphite, also known as the Acheson furnace, is still in use today. The electric resistance furnace with carbonaceous material as the furnace core generates graphite by heating the mixture of quartz SIO2 and carbon.Several events about graphiteGraphite was first discovered in

How to classify the carbon material production industry

In the development history of China's carbon material industry, the management scope is mainly divided according to the application direction and distribution system of carbon materials. There are roughly the following types of carbon material production enterprises:(1) A carbon material enterprise that produces graphite electrodes, graphite anodes, carbon blocks for metallurgical furnaces, and self baking electrodes primarily for the steel, metallurgical, and chemical industries. Its main products are graphite electrodes, graphite anodes, carbon blocks, and electrode paste for electric arc furnaces. The equipment and technology for producing graphite electrodes can also be used to produce high-strength, high-purity, and high-density graphite. These carbon materials have a wide range of applications in the nuclear industry, aerospace industry, and other industries.(2) Enterprises that produce carbon materials for power supply and aluminum electrolysis. The electrolytic aluminum indust

Electromagnetic properties of carbon and graphite

Artificial graphite is not necessarily a good conductor of electricity, but structurally belongs to the so-called polycrystalline graphite. Polycrystalline graphite is a carbon material with good graphitization performance obtained by heating at high temperatures. Carbon materials are generally obtained by treating organic matter in a reducing atmosphere, inert atmosphere, or vacuum. The carbon material obtained by heating below 1000 ℃ is not called carbonized material, but rather considered as an insulator. Only by heating the carbonized material above 1000 ℃ can the specific resistance rapidly decrease and become a good conductor of electricity. The polycrystalline graphite obtained by this method is still a carbon material in a sense, and artificial graphite requires temperature treatment above 2500 ℃ under atmospheric pressure. The change in electrical properties of carbon materials and carbides during simultaneous heating treatment is a very interesting and profound issue.A solid

What should be paid attention to when processing refractory materials with flake graphite?

Do you know what is the difference between graphite powder and coal powder?

The chemical elements of the two are the same, but the structure is completely different. The coal is a molecular crystal, and the graphite is a atomic crystal. Usually we usually say that C powder is molecular crystals.Graphite: Natural crystal graphite, shaped like fish phosphorus, is a hexagonal crystal system, with layer -like structure, high temperature resistance, conductivity, heat conduction, lubrication, plasticity, acid and alkaline resistance. The scale graphite is divided into four categories according to the fixed carbon content: high pure graphite, high carbon graphite, medium carbon graphite, low -carbon graphite.Graphite powder is soft, gray -black; raw materials have heat -resistant conductivity, which can be used as refractory insulation materials, conductive raw materials and wear -resistant moisturizing raw materials. Graphite's unique process is processed into milk products. It is smooth and exquisite in viewing. It must use containers such as barrels and other co

What are the characteristics of the thermal stability of the film -shaped graphite

Sheet -shaped graphite is a natural ore, with a thin piece or scale, and the aggregate is in the form of soil. It is a hidden crystal. Film graphite has many high -quality physical and chemical characteristics, including good thermal stability. Compared with other products, the thermal stability of film -like graphite has great advantages.Film graphite is one of the most high -temperature -resistant materials at present. Generally, the strength of the material is gradually decreased at high temperature. However, when heating to 2,000 degrees Celsius, the strength of the sheet -shaped graphite is twice the temperature at room temperature.Sheet -shaped graphite has excellent heat shock resistance. When the temperature suddenly changes, the thermal expansion coefficient is small, so it has good thermal stability. When the temperature changes rapidly, cracks will not occur.Sheet -shaped graphite is a material with excellent thermal shock. For graphite electrodes used in electric furnace s
