2023-05-17Defense 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
2023-05-17Graphite 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,
2023-05-16Graphite is widely used in the electrical industry for electrodes, brushes, carbon rods, carbon pipes, mercury tubes, cashiers, cashmerers, telephone parts, televisions, coatings of televisions, and so on. Among them, the application of graphite electrodes is the most widely used. When smelting various alloy steel and iron alloy, use graphite electrodes. At this time, the powerful current passes through the melting area of the electric furnace to generate an arc, which translates the electric energy to the heat energy, and the temperature is increased to the left and right. So as to achieve the purpose of melting or reaction. In addition, when electrolytic metal magnesium, aluminum, and sodium, the anode of the electrolytic groove also uses graphite electrodes. The resistance furnace that produces rigid sand was also used as a furnace head conductive material with graphite electrode. The graphite used in the electrical industry is high in granularity and taste. For example, alkaline b
2023-05-16Magnesium carbon brick -and -magnesium carbon resistance materials were in the middle of the age. It was successfully developed by the United States. In the age, the Japanese steel refining industry began to use magnesium carbon bricks in water cooling electric arc furnaces. Magnesium carbon bricks have been used in large quantities worldwide, and have become a traditional use of graphite. At the beginning of the age, magnesium carbon bricks began to blow the furnace lining of the oxygen top.Aluminum carbon brick and aluminum carbon resistance materials are mainly used for continuous casting, flag cover of flat steel billet transmission pipelines, underwater nozzles, and oil well explosion cylinders. Steel that is continuously cast in Japan accounts for above the total production volume.The molding and refractory 坩埚 of the relevant products and the fire -resistant 坩埚 and its related products, such as 坩埚, curly bottle, plug head and nozzle, etc., have high fire resistance, low thermal
2023-05-16First, graphite products have good adsorption.The gap structure of charcoal makes charcoal good adsorption, so charcoal is often used as adsorption materials for adsorption of water, odor, toxic substances, etc. We have done experiments. The graphite baking sheet used in the barbecue a few days ago looks very clean, but it will be heated on the induction cooker. We will see the fat and harmful substances adsorbed during the last time. Wipe it with a clean dining paper and use it.Second, graphite products have good thermal conductivity, fast heat transfer, uniform heating, and saving fuel.The baking sheet made of graphite, the pot, etc. heated quickly, and the fired food is evenly heated, cooked from the inside, the heating time is not only pure, but it can also lock the original nutrients of the food. We have done experiments. When we use graphite baking pan to barbecue, the induction cooker is hitting the fire at the beginning. It can be preheated in only 20-30 seconds. When you star
2023-05-15How to avoid the corrosion of the equipment on the equipment, thereby reducing equipment investment and maintenance costs, and improving production efficiency and profits is a problem that each chemical enterprise always needs to solve. Many products are resistant to corrosion but not high temperature, but scales graphite has both advantages. 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. Scales graphite also has good thermal conductivity. It is the only non -metallic material with a thermal conductivity higher than the metal. The thermal conductivity coefficient is 2 times that of carbon steel and 7 times that of stainless steel. Therefore, it is suitable for 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, includin
