    What is graphite

    Time：2023.02.07Browse：1

    Share:


    Graphite is a kind of homogenous alien body for carbon. It is gray -black, opaque solid, stable chemical properties, corrosion resistance, and it is not easy to react with drugs such as acid and alkali. Natural graphite comes from graphite ore. It can also be used as a raw material for oil coke, asphalt coke, etc., and made a series of processes to make a human -made graphite. Graphite is burned in oxygen to generate carbon dioxide, which can be oxidized by strong oxidant such as concentric acid and potassium permanganate. It can be used as an anti -wear agent and lubricant. High -purity graphite is used as a neutron decelerator in the atomic reactor. It can also be used to manufacture crickets, electrodes, brushes, dry batteries, graphite fibers, heat exchangers, coolers, arc furnaces, and arc furnaces, and arc furnaces, and arc furnaces, and arc furnaces, and arc furnaces, and arc furnaces. Arc light, pencil core, etc.

    Basic overview of high-purity graphite?

    High purity graphite is widely used in various industries, so its use is definitely very extensive. In fact, this high-purity graphite mainly means that the carbon content of graphite is more than 99.99%. It is also widely used in advanced refractory materials and coatings in metallurgical industry, stabilizers for military initiating explosive devices, pencil lead in light industry, carbon brushes in electrical industry, electrodes in battery industry, catalyst additives in fertilizer industry, etc. Of course, the scale crystals of the product are complete, thin and tough, with excellent physical and chemical properties. It has good thermal conductivity, temperature resistance, self-lubrication, conductivity, thermal shock resistance, corrosion resistance, and other properties. In addition, the high-purity graphite (also known as flake high thermal conductivity carbon powder) mentioned today has high strength. Of course, in addition to this, it also has advantages such as good therma

    Graphite products and other purposes

    Defense industryIn the defense industry, the nozzle of solid fuel rockets is also used to make solid fuel rockets, the nasal cone of the missile, the parts of the universe navigation equipment, the insulation material and the anti -ray material.Anti -anti -rust and anti -rust materialGraphite can prevent boilers from scaling. Tests from relevant units show that adding a certain amount of graphite powder (about use per ton of water) to the water can prevent the surface of the boiler from scaling. In additionWith the continuous development of science and technology, people have also developed many new uses on graphite. Flexible graphite products. Flexible graphite, also known as expansion graphite, is a new graphite product developed in the age. The United States has studied successful flexible graphite sealing materials, solving the problem of atomic energy valve leakage, and then Germany, Japan, and France have also begun to develop and produce. In addition to the characteristics of n

    What you need to know in the daily use of graphite mold

    Due to the special structure of the graphite mold. Therefore, in daily use, these special properties should also be understood by us.1. High temperature resistant type: the melting point of graphite is 3850+50°C, and the boiling point is 4250°C. Even in ultra-high temperature arc burning, the thermal expansion coefficient is very small, and the strength of graphite increases with the increase of temperature. At 2000°C , graphite strength increased - times;2. Lubricity: The lubricating performance of graphite depends on the size of the graphite flakes. The larger the flakes, the smaller the friction coefficient and the better the lubricating performance;3. Plasticity: Graphite has good toughness and can be made into very thin sheets;4. Chemical stability: Graphite has good chemical stability at room temperature, and is resistant to acid, alkali and organic solvents;5. Thermal shock resistance: When graphite is used at room temperature, it can withstand drastic changes in temperature wi

    Precautions during the storage process of carbon material raw materials

    (1) The storage site for carbon raw materials must be a cement floor, and the mixing of external impurities should be minimized when storing raw materials.(2) During the storage of raw materials, it is strictly prohibited to mix dust, sediment, and other impurities. It is best to store low ash materials in storage, and urgently needed raw materials should be kept in stock. For spare raw materials, if there is no warehouse for storage, they can also be stored outdoors, but management must be strengthened and appropriate measures must be taken.(3) During the storage period, carbon raw materials should be prevented from mixing with each other, especially to prevent more ash raw materials from mixing with less ash raw materials. If the raw materials are mixed, they should be downgraded for use. For the same type of raw materials, if the quality inspection results differ significantly, they should be stacked separately.(4) To prevent rain and snow from soaking in raw materials, it is neces

    The application of scales in the casting industry

    1. Scales graphite is the main raw material for the casting industry.During the casting process, the scale graphite should be added to the casting, which helps the product to complete it faster and better, and improve the quality of the casting product. Therefore, the scale graphite for casting is the key raw material for the casting industry.2. How is graphite used to cast?Processing the cast -specific scales graphite into powder, and then add it to the outer surface of the casting and casting to make the casting easy to remove the mold. Casting dedicated scales graphite improves the surface quality of the casting, making the castings more abrasion and high temperature. This is the application of cast -specific scales graphite in casting and its abrasion resistance and high temperature resistance. There are many specifications for casting special sliced graphite powder. In different cast production areas, different thermal scale graphite should be used with different aims of casting.
