Graphite heater

Graphite powder from graphite manufacturers is a widely used industrial material

Graphite powder produced by graphite manufacturers is a widely used industrial material, obtained by crushing, grinding, and screening high-purity graphite through rolling. The key to the type of graphite powder is the particle size, which varies from 50 to 30000 mesh. The more mesh the screen, the finer the particle size, and the higher the price. Previously, our country's technological strength could not be reached, and high-end graphite powder had to rely on imports. However, at present, Chinese manufacturing enterprises have introduced cutting-edge overseas powder mills, which can produce and manufacture fine graphite powder with global particle size, and have been used in many industries both domestically and internationally.Graphite manufacturers offer various types of graphite powder, including lubricating graphite powder, conductive graphite powder, nanotechnology graphite powder, high-purity graphite powder, and graphite powder screens with a mesh size of 150, 425, 1000, 3000

Mechanical performance of expansion graphite at different temperatures

Expansion graphite has excellent chemical stability, heat resistance, sealing, self -lubricating, radiation resistance and high heat -conducting. It is widely used in industrial fields such as machinery, oil, chemical, metallurgy, aerospace, navigation, transportation, and transportation. It is an ideal advanced sealing material. The mechanical property of expanded graphite may be different at different temperatures.1. Within the temperature range of 400 degrees Celsius, the compressed elastic modulus, rebound rate, and compression rate of expansion graphite sealing materials are not significantly affected by the temperature, and the impact is not greatly affected.2. There are significant differences in the compression modulus, rebound rate, and compression rate of two samples made of different materials formulas and processes, and there are also appropriate differences in the compression strength.3. Within the temperature range from room temperature to 400 degrees, the pressure resis

Battery material, promote renewable energy development

In recent years, with the increasingly serious problems of environmental pollution and energy shortage, renewable energy as a clean, low -carbon, and sustainable development model has gradually been given important strategic significance. Among the applications of renewable energy, batteries as energy storage equipment are also an indispensable part of them. In order to further promote the development of renewable energy, we need to continuously explore new battery materials to improve the power density, cycle life and security of the battery.At present, researchers have proposed many new battery materials, such as lithium ion batteries, sodium ion batteries, zinc air batteries, etc. These battery materials can better meet the needs of energy storage and utilization compared to traditional lead -acid batteries, nickel -metal hydride batteries. Moreover, in the production process, the energy and materials they consume are also greatly reduced, which is more in line with the requirement

Some related knowledge of mold processing

1. Use as conductive materialsWhen using an arc furnace or mineral heat electric furnace to smell all kinds of alloy steel, iron alloys or production stones (carbonized calcium), and yellow phosphorus, strong current passes through carbonic electrodes (or continuous self -roasting electrodes -that is, electrode paste) or graphite electrode introduction The melting area of the electric furnace generates an arc, which translates the electrical energy into thermal energy, and the temperature increases to about 2000 degrees Celsius, so as to meet the requirements of smelting or reaction. Metal magnesium, aluminum, and sodium are generally removed with melting salt electrolysis. At this time, the anode conductive material of the electrolytes use graphized electrodes or continuous self -baking electrodes (anode paste, sometimes pre -baking anode). The temperature of melting salt electrolytic is generally below 1,000 degrees Celsius. The anode conductive material for producing alkaline (sodi

Precautions for using flake graphite?

Flake graphite is a natural crystalline graphite that resembles fish scales and belongs to the hexagonal crystal system with a layered structure. Therefore, it still has good properties such as high temperature resistance, conductivity, thermal conductivity, lubrication, plasticity, and acid and alkali resistance. Below are some precautions for using flake graphite?Flake graphite is a widely used product in the metallurgical industry for refractory materials and coatings. Such as magnesia carbon bricks, crucibles, etc. Now used as anti-corrosion material. Flake graphite is an anti rust primer made of carbon black, talc powder, and oil, which has good resistance to chemicals and solvents. If chemical pigments such as zinc yellow are added to the formula, its rust prevention effect will be better. When used, it has strong thermal shock resistance and good corrosion resistance, and is the main carbon raw material used in conjunction with refractory materials. It has a significant impact
