The main characteristics of artificial graphite

Crystal structure

Graphite artificial synthesis

(1) Taking natural scales graphite as raw materials, use Hummers legal oxygen graphite, and use thermal peeling into graphene, or use ultrasonic dispersion to divert into graphene, and then chemically restore into graphene. Use SEM, TEM, HRTEM, XRD, and RAMAN systems to examine the appearance and structure of graphene.(2) Taking graphene as the basis, titanate tetraododes as titanium sources. First, the solution-water thermal legal system is used to prepare titanium dioxide/graphene nano-composite materials. Use XRD, SEM, TEM, and RAMAN to characterize the crystal structure, granular appearance and chemical composition of titanium dioxide/graphene nano -composite materials. The results show that the synthetic titanium dioxide nanocrystal is a sharp titanium structure, the crystalline condition is good, titanium dioxide and graphite The composite effect is better. The photocatalytic performance of nano crystals was studied, and the results showed that titanium dioxide/graphene catalyti

What is the difference between scales graphite and asbestos?

1. Scale graphite has better high temperature resistance performanceThe scale of the scale graphite enhanced composite pads can withstand the high temperature of 1650 ° C. Even if the chemical equipment is melted, it is still safe and intact. When the asbestos products are at 500 ° C, the crystalline water inside will decompose to make itself powder and lose its effect. In many industrial fields, it is carried out at high temperatures. The nature of scales graphite makes it more suitable for this role.2. Synthine graphite is easier to useThe pads of scales graphite are only half of asbestos products, which means that to achieve the same sealing effect, the power of tightening the screw can be much smaller. The scales graphite not only has the above obvious characteristics, but also has excellent sealing performance, good compression, elasticity, elasticity, elasticity, The characteristics of good antioxidant, strong self -lubrication and plasticity, good conductivity, high gravity, an

How to turn a graphite block into a carbon increase agent

How to turn graphite blocks into carbon increases Gentle blocks are indispensable in the production process of carbon and graphite products in the production process of carbon and graphite products. Equipment external forces to get rid of the adhesion between the molecular structure of the raw material and break the raw materials. Since then, everyone can divide them into rough, shattered, sophisticated, fine grinding, etc., but they can divide them according to the broken and boring size and their particles. The same industrial production has a broken specification for different industrial production.Today, as far as everyone is concerned, the three crushing levels in the production of graphite products can be divided into pre -fragmentation, medium crushing and fine grinding. The crushing in front of the burning furnace is generally broken up to 50-70mm on the large graphite block of 200mm. The medium crushing means that the particle size is broken after forging. At this moment, the

Introduce the asphalt rubber pendant penetration processing process

The general operating process of graphite immersion is after being loaded into the product, first vacuum packaging (gas in the gas in the pores in the pores of the product) and then put it in the impregnation agent to submerge the product, then pressure it to the liquid level, so that Essence It is used for different intentions, and the standards of impregnation agent processing process are not thorough. Below, I will introduce the asphalt rubber mud impregnation processing process of graphite board in detail.The whole process of processing the processing technology of asphalt rubber -soaking small graphite board, electrode connector and its graphite anode board:First of all, the semi-finished processing surface of the graphite board was burn, and then put it into the product box and put it in the temperature of about 4 hours in the temperature of about 240-Soot. After the heat, the product is quickly installed into the impregnation tank with the iron frame (the immersion can be heate

Carbon and graphite products

（1） Graphite electrodes are mainly made from petroleum coke and needle coke as raw materials, and coal tar pitch as a binder. They are made by calcination, batching, kneading, pressing, roasting, graphitization, and machining. They are conductors that release electrical energy in the form of an arc in an electric arc furnace to heat and melt the furnace material. According to their quality indicators, they can be divided into ordinary power, high power, and ultra-high power. Graphite electrodes include:(1) Ordinary power graphite electrode. Allowing the use of graphite electrodes with a current density below 17A/cm2, mainly used for ordinary power electric furnaces such as steelmaking, silicon smelting, and yellow phosphorus smelting.(2) Anti oxidation coated graphite electrode. A graphite electrode coated with an antioxidant protective layer on the surface forms a protective layer that is both conductive and resistant to high-temperature oxidation, reducing electrode consumption duri

Why add graphite powder to glass fiber?

Glass fiber enhanced plastic (FRP) is a composite composite material based on synthetic resin. It has the advantages of light weight, high strength, corrosion resistance, microwave transmission, electrical insulation, and reasonable performance design according to requirements. It has been widely used in aerospace, petrochemicals, transportation, construction, shipbuilding, machinery, environmental protection, textile and other fields. Glass fiber enhanced plastic (FRP) has good electrical insulation property. Under normal circumstances, the amount of graphite powder is 2.5 ~ 5%, which can reach 30 ~ 50%. So why add graphite powder to glass fiber?From an economic and technological perspective, it is best to choose inorganic abrasive materials, so the amount of graphite powder in the abrasion -resistant material of the glass fiber reinforcement is relatively large. In short, glass fiber wear -resistant materials, because its matrix is a polymer material, fills solid lubricants and vari

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

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.
