Pure method of high -carbon graphite

The flotation method is a type of energy consumption and reagent consumption and low cost in the conventional purification method of minerals. This is the advantage of the floating method purification method. For scales -shaped graphite, multi -segment mills cannot be completely unbuttoned, but they are not conducive to protecting large scales of graphite. Therefore, the use of flotal methods to further improve the graphite taste. High carbon graphite containing more than 99%of carbon must use chemical methods to use graphite.(1) Pure method of alkaline acid. The carbon content after the purity method of alkaline acid method can reach more than 99%, which has the characteristics of less one -time investment, high product quality, and strong process adaptability. The purity of metal mines can adopt the advantages of alkaline acid method). The alkaline acid method is a wide range of methods in my country today; its disadvantages are large energy consumption, long response time, large gr

The application of scales graphite in rust protection

Scale graphite should be no stranger. The scales graphite is very wide, such as lubrication, conductivity, etc. So what are the applications of scales graphite in rust?Apply the scales graphite on a solid and then put it in the water. We will find that the solids that have been applied by the scales will not be wet by the water. Even if it is soaked in water, it will not be wet. The layer protective film is separated from the water from water, which is enough to indicate that the scale graphite is not soluble in water. Using the characteristics of graphite can be used as a good rust -proof paint, coated with metal chimneys, roofs, bridges, pipes, and can effectively protect the metal surface from corrosion of atmosphere and seawater, and has good anticorrosive rust and anti -anti -rust performance.This situation is often encountered in life. The connection bolt or steam pipe flange of the cleaning equipment is very easy to rust, which brings great trouble to maintenance and disassembl

Graphite powder has the cause of self -lubrication performance analysis

Graphite powder is a wear -resistant material, and its self -lubrication performance is its most important feature. Graphn powder has a good self -lubrication performance due to its special layer -shaped crystal structure. The following are the analysis of the reasons for the self -lubricating property of graphite powder:The carbon atoms in graphite lattles are arranged in hexagonal on different planes. The distance between the carbon atoms in the same plane layer is 1.42 meters, and the distance between the carbon atom of each plane layer is 3.35. They are staggered along the same direction, repeat the position of the first plane in the third plane, the fourth plane repeats the position of the second plane, and so on. In each plane layer, because the carbon atoms are relatively tight, the binding forces between them are relatively large, and the carbon atom between layers and layers is far from each other, which is easy to separate and relatively slide. This is the main reason why gr

The best way to improve the life of graphite boards to use antioxidant solution

The best way to improve the life of the graphite board is the success of anti -oxidation solution with the development of graphite boards. After delivery and use in many industries, there will still be more and more technical advantages and characteristics in many levels. Among them, the continuous improvement of processing work capacity will still be unusual in the advantages and performance levels of its talents. In more cases, they all feel that their technical standards will still be higher and higher. The selection generated will still have a difference.Therefore, what are the aspects of their technical advantages? Below my graphite board manufacturer in Shanxi Province will introduce the old iron in detail:The antioxidant solution has good performance. Generally speaking, in the whole process of the construction of graphite board projects, the provisions of anti -oxidation levels are getting higher and higher, especially as a wall insulation layer. The advantage can be seen that

Graphite products corrosion -resistant materials

Graphite has good chemical stability. After special processing graphite, it has the characteristics of corrosion resistance, good thermal conductivity, and low penetration rate. , Pump and other equipment. These devices are used in industrial departments such as petrochemical, wet metallurgy, acid -base production, synthetic fiber, and papermaking, which can save a lot of metal materials. 0 for casting, sandwiches, molding, and high temperature metallurgical materials, due to the small expansion coefficient of graphite, and can resist the changes in cold, cold and hot, can be used as the cast mold of glassware. After using graphite The rate is high, and it can be used without processing or processing, so a large amount of metal is saved. The production of hard alloy and other powder metallurgical processes is usually made of graphite materials to be used to durable souls. The crystal growth of single crystal silicon, regional refining containers, brackets, fixtures, inductive heater,

Graphite

One of the main purposes of graphite is to produce refractory materials, including refractory bricks, crickets, continuous casting powder, molding cores, mold casting, detergent and high temperature resistance. In recent years, the two important changes in the refractory material industry are that magnesium carbon bricks are widely used in the inside of the steelmaking furnace, and the application of aluminum carbon bricks in continuous casting. The refractory material for graphite is closely connected to the steelmaking industry, and the refractory material consumed by the steelmaking industry around the world.Because graphite has many excellent performance, it has been widely used in industrial departments such as metallurgy, machinery, electrical, chemicals, textiles, and national defense. Can be used as refractory materials. Graphite products maintain the chemical characteristics of the original scales graphite and have strong self -lubrication performance. The characteristics of

High pure graphite

High pure graphite generally refers to graphite with carbon content of more than 99.99%. It can be divided into three types: coarse particle structure, fine particles structure, and ultra -fine particle structure in the tissue structure. In the furnace. The basic materials of the integrated circuit are mainly silicon single -crystal chips. The current growth process of silicon single crystal mainly adopts a direct pull (CZ) method. Other methods include the magnetic field direct pull method (MCZ), the area (FZ) method, and the double -yarm pull crystal method Law, the global electronic industry uses straight single -crystal silicon to account for 80% of the total amount of single crystal silicon. The graphite in the direct pull single crystal silicon furnace is consumables. Heating system. In 2005, China needed a straight silicon single -crystal furnace to use about 800 t.Another important purpose of high pure graphite is processed into various types, which are used to produce preciou

Graphite mold mold polishing

The mold polishing of graphite mold is accompanied by the common use of plastic products, such as daily chemical tools and drink packaging materials. The appearance must usually specify the surface of the injection molding mold concave mold to be polished. The production of optical lenses, laser laser records and other molds are extremely high in surface roughness, so the provisions of polishing and polishing are also very high. Following and polishing not only enhances the beautiful and generosity of product workpieces, but also improves the corrosion resistance and abrasion resistance of the surface of the raw material, but also enables the mold to have other advantages, so that plastic products are easy to produce and reduce the time of production and manufacturing injection processing cycle. Therefore, polishing and polishing is an important process in the process of injection molding.The mold polishing has two meters; one is to increase the smoothness of the mold, so that the sur
