2023-05-15One 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
2023-05-15The high -carbon graphite extraction method and the flotation method is low in the purity of minerals and the loss of reagents. This is the advantage of purifying high -carbon graphite. However, the application of floating and purifying graphite can only make the graphics of graphite unlimited improvement. For sheet -shaped graphite, not only can not solve its complete monomer, but it is not conducive to maintaining large hungusgogi. High carbon graphite must be chemically purified for graphite.(1) Pure method of high carbon alkali acidic acid. The carbon content purified by alkaline is more than 99%of the carbon content, which has the characteristics of less one -time investment, high product grade, and strong process adaptability. It also has a strong generality. The purity of non-metal minerals can use the advantages of alkali-acid method, and the alkali-acid method is the most commonly used method in my country today.(2) High -carbon graphite chloride and roasting method. The chlo
2023-05-10Graphite is one of the better minerals in my country. This new type of natural graphite material produced and processed by new technology has played a key role in various industries such as electronic devices, chemical factories, light industry, military industry enterprises, national defense safety, aerospace and other industries. The spherical graphite is based on high -quality high -carbon steel natural scales graphite as the raw material. It uses advanced manufacturing processes to modify the surface of graphite to produce graphite products with different fineness and near -ellipse spherical.First: Graphite is divided into crystal graphite (shell -like) and hidden crystal graphite (soil) according to the crystal degree. Ballog graphite is suitable for spherical or spherical graphite products processed by mechanical and physical methods with natural scale graphite. It emphasizes that the physical and chemical performance of natural graphite should meet the following requirements:Se
2023-05-10With the development of social industry, graphite has been regarded as one of the important industrial minerals at home and abroad. In recent years, with the development of graphite processing technology, graphite parts have played an important role in all walks of life.China-carbon graphite workpiece maintains the original scales graphite original resistance, corrosion resistance and physical properties, high temperature resistance of 3000 degrees, low temperature-204 degrees, pressure resistance is greater than 800kg/cm2, and the pressure resistance is large in 450 degrees air. Lost 1%, rebound rate of 15-50%, strong self-lubrication performance.According to the needs of different industries, the graphite materials are made into different Chinese carbon graphite pieces. In order to improve the performance of graphite, graphite tablets are specially treated. It plays an important role in many fields such as wear -resistant and antioxidant.With the continuous development of science an
2023-05-10How to avoid the corrosion of the equipment on the equipment, thereby reducing the cost of equipment investment and maintenance, and improving production efficiency and profit. It is a problem that each chemical enterprise always needs to solve. Many products are resistant to corrosion but high temperature. Both. The following editors will introduce the problem of the device corrosion in detail how to solve the equipment of the scales:1. Excellent thermal conductivity. The scales graphite also has good thermal conductivity. It is a non -metal material with a thermal conductivity higher than the metal. It ranks in the front position in non -metal materials. Heat transfer equipment.2. Excellent corrosion resistance. Various types of carbon and graphite have excellent corrosion resistance to all concentrations of hydrochloric acid, phosphate and hydrofluoric acid, including fluoride-containing medium, and the maximum use temperature is 350 ° C-400 ° C. It is the temperature that starts t
2023-05-10Scales graphite has good conductivity and thermal conductivity. It is widely used in sealing, lubrication, metallurgy, chemical industry and other industries. Different industries have different requirements for the specific parameters of scales graphite. Choosing the correct graphite graphite is closely related to its effect. Today, I will explain the correct method of choosing the graphite size of the scale:1. The effect of scale graphite particle size on expansionThe degree of particle size on the expansion of scales also has a certain effect. After experiments, the expansion rate of scales graphite is directly proportional to the particle size of graphite. The expansion graphite has a rich pore structure. The smaller the grain size of the graphite. The smaller, the lower the expansion coefficient, and vice versa. Therefore, in the fields of sealing and fire -resistant coatings, large -scale scales should be selected as materials.2. The effect of scale graphite particle size on smo
