What kind of wonderful use of graphite powder?

Graphite powder is widely used. Resources are carbon products, and the melting points are very high. Graphn powder can withstand high temperatures above 3000 ° C. Therefore, graphite powder has excellent high temperature resistance, and graphite powder resistance high temperature resistance can be widely used in high temperature resistance fields. Graphite powder is widely used in high temperature resistance. Casting is carried out in high temperature environments. In order to prevent the casting from deforming and broken at high temperatures, it is necessary to add graphite powder to the casting. Casting graphite powder can withstand the high temperature generated during the forging process, make the surface of the casting clean, without sticky sand, and ensure the quality of the casting.Graphite powder has unique physical chemical properties with high temperature resistance, corrosion resistance, good toughness, good thermal conductivity, good conductivity, and high carbon content.

Let's take a look at the uses of battery specific graphite in industrial applications

The special graphite for batteries has good chemical stability, and the specially treated graphite has the characteristics of corrosion resistance, good thermal conductivity, and low permeability, so it is widely used to make heat exchangers, reaction tanks, condensers, combustion towers, absorption towers, coolers, heaters, filters, and pumps, and is widely used in petrochemical, hydrometallurgy, acid-base production, Synthetic fiber, paper making and other industrial sectors, Can save a large amount of metal materials.It is a material for casting, casting, pressing and high-temperature metallurgy. Because of its low coefficient of thermal expansion of graphite and its resistance to rapid cooling and heating, it can be used as a mold for glassware. After graphite is used, Ferrous can be used to obtain castings with accurate size, smooth surface and high yield, which can be used without machining or slightly processing, saving a lot of metal. In the powder metallurgy process of produc

Selection and use of graphite

What are the choices of is used for refining, and usually the temperature is extremely high. Therefore, the raw materials for manufacturing should have high refractory resistance and have a strong high temperature resistance coefficient. There are also sufficient strength of ingredients. If the impact of high temperature, etc. during the smelting process, there will be wear. Therefore, if the strength of the raw material is not high, it is likely that the more waves will be used, and the more toughness will be lacking. The contraction coefficient must be small, and the temperature changes sharply without deformation and breaks. There must be not to afford the chemical response with the melted metal in the selection of materials, and the high temperature resistance of chemical metals should be high. Loss. When the melting metal is demanded at high temperature, the selection of should ensure that chemical stability at high temperature should be learned. It can be seen that there are a

Graphite flotation method

Floating is a commonly used and important mineral method. Graphite has good natural floating. Basically, all graphite can be purified by floating methods. In order to protect graphite scales, most of the graphite flotation uses multiple sections of processes. Graphite flotation collecting agents are generally used for kerosene, with a dosage of 100 to 200g/t. The foaming agent is generally used with pine or butad ether, and the amount is 50 to 250g/t.

Spherical graphite

The spherical graphite is based on high -quality high -carbon natural scales graphite as the raw material. It uses advanced processing technology to modify the surface of graphite. The production is different, like an oval spherical graphite product.Ballog graphite material has good conductivity, high crystallization, low cost, high theoretical embedded lithium capacity, low charging potential and flat, and is an important part of the lithium -ion battery negative material. Replacement products have excellent conductivity and chemical stability, high charging capacity, long cycle life, and green environmental protection.The spherical graphite processing process is first to form initial products spherical graphite through rough, repair, magnetic selection and other processes in the spherical graphite workshop, and then enter the purified workshop and enter the high temperature and purify it into high purifiers.There are two main indicators to measure the quality of spherical graphite,

The purpose of graphite machining

Various carbon graphite products, although they have a certain shape and size after forming, undergo expansion and contraction, deformation and bending, collision or corner dropping during the process of roasting, impregnation, and graphitization treatment from the pressed blank to the graphitized blank. The surface adheres to some fillers and insulation materials, resulting in roughness and unevenness. Their shape and size change to a certain extent, and they cannot achieve the shape of the product during use, Due to strict requirements for size and surface roughness, it cannot be used without mechanical processing. In addition, some products have complex structures and shapes that cannot be directly produced by forming methods, such as metal continuous casting and rolling graphite crystallizers, electric spark machining graphite molds, carbide sintering graphite boats, discs, and other special graphite products. Some products require interconnection when used, such as the connection
