Introduction to Graphite Carbon Products

1. Used as refractory material: Graphite and its products have properties of high temperature resistance and strength, and are mainly used in the metallurgical industry to manufacture graphite crucibles. In steelmaking, graphite is commonly used as a protective agent for steel ingots and as a lining for metallurgical furnaces.2. As a conductive material: used in the electrical industry to manufacture electrodes, brushes, carbon rods, carbon tubes, positive electrodes for mercury positive current transformers, graphite gaskets, telephone parts, coatings for television tubes, etc.3. As a wear-resistant lubricating material: Graphite is often used as a lubricant in the mechanical industry. Lubricating oil often cannot be used under high-speed, high-temperature, and high-pressure conditions, while graphite wear-resistant materials can work without lubricating oil at high sliding speeds at temperatures of 200-2000 ℃. Many devices that transport corrosive media are widely made of graphite m

What are some related knowledge points about high-purity graphite?

The application fields of high-purity graphite include metallurgy, military, light industry, electrical battery industry, and fertilizer. Can it be called high-purity graphite? In order to make more people familiar with it, here are some related knowledge points about high-purity graphite for everyone? I hope you can bring some better help when choosing in the future.High purity graphite is widely used in fields such as metallurgy, machinery, environmental protection, chemical industry, electronics, medicine, military industry, and aerospace. It has high purity and high strength graphite properties. In fact, the existence of graphite flakes now makes graphite have excellent lubricity. Generally speaking, the larger the ordinary graphite flakes, the better their lubricity. When we use it, we need everyone to know that the graphite industry technology is still at a relatively low level in the world, and the products are mainly raw materials and initial processing products. Therefore, th

The artificial synthesis process and equipment application of scales graphite

At present, the production process of scales graphite is to produce graphite products through the production of natural graphite ore through the production, ball grinding, and flotation, and provide artificially synthetic scale graphite production technology and equipment. Using this device, the grinding graphite particles can be reinstated into large -shaped graphite to improve the utilization rate of graphite. The following editor introduces the artificial synthesis process and equipment application of scales in detail:This device has two relatively rotating ring rules semi -round tanks, or two irregular semi -circular grooves that can be relatively rotated, one of which is fixed as a fixed ring groove, and the feed pores are engraved on the fixed ring groove; The power connection allows the power to drive it to rotate. It is a cycle groove, engraved with the material outlet, and the gap between the fixed ring groove and the mobile ring groove can be adjusted; when the two ring groo

Unique chemical properties of industrial graphite products

Graphite is an important mineral resource in the 21st century, and China ranks first in the world in terms of graphite ore reserves. With the improvement of graphite product processing technology, it has been widely used in fields such as chemical engineering, smelting, casting, new materials, molds, aerospace, etc. We often see many chemical properties of graphite products in the industry, such as graphite crucibles, graphite heaters, graphite molds, etc(1) High temperature resistance: In smelting, the melting point of graphite products is 3850 ± 50 ℃, and the boiling point is 4250 ℃. Even after being ignited by an ultra-high temperature arc, the weight loss and thermal expansion coefficient are very small. The strength of graphite increases with temperature, and at 2000 ℃, the strength of graphite doubles.(2) Good conductivity and thermal conductivity: The conductivity of graphite products is 100 times higher than that of ordinary non-metallic minerals. The thermal conductivity exce

What should be paid attention to when processing refractory materials with flake graphite?

Graphite Product Materials advantage

Graphite products (including graphite rods, graphite products, graphite blocks, graphite boards, graphite carbon pipes, graphite rings) are important strategic resources. Graphite is a degeneration of carbon substances, which is most common in Dali, sliced rocks, or hemp rocks. The coal seam can form graphite through the thermal deterioration, while a small amount of graphite is a native mineral of fire rock.The industrial graphite ore is divided into two categories: crystal (scale) graphite ore and steady crystal (earth -shaped) graphite ore. Crystal graphite ore can be divided into two types: scale -like and dense. Chinese graphite ore is the type of scales -like crystal, followed by hidden crystal type, and dense crystal graphite is only seen in individual mining plants such as Tocobra, Xinjiang.Due to its special structure, graphite products are resistant to high temperature resistance, heat shock resistance, conductivity, lubrication, chemical stability, and plasticity.

Application of graphite

1. Sealing materials: Mix the raw material high -carbon graphite with concentrated sulfuric acid and concentrated nitric acid for acidification, and then suppress the molding after heat treatment. The prepared flexible graphite is a new type of high -performance sealing material. Compared with traditional sealing materials such as asbestos rubber, it has good performance of compression, reflection, elasticity, self -adhesion, low density, etc., and can be used for a long time under high temperature and high corruption. The graphite board and sealing elements made are widely used in industries such as Aerospace, Machinery, Electronics, Nuclear Energy, Petrochemical, Power, Ship, Small, and other industries. The excellent characteristics of lubrication, plasticity and chemical stability are known as the "king of sealing" in the world.2. The field of environmental protection: The expansion graphite obtained by high temperature puffing has a rich hole structure, so it has excellent adsorp
