Many new main uses of graphite have already been developed and designed

Many new main uses of graphite have long been developed and designed with the development trend of scientific and technological progress. Graphite has many new main uses. High -purity graphite products are used for high -purity metallurgical industry, electronics industry, Chinese nuclear industry and mold processing; general graphite products can be used as a wall -building raw material for mining with aluminum electrolytic grooves, non -metallurgical tunnel furnaces, and non -ferrous metal furnaces. Calcium residual raw materials can be used as carbon increases for ironmaking industry. There are many types of carbon quality raw materials used to seepage nitrogen, including artificial synthesis of graphite, petroleum coke, casting focus, and pure natural graphite.Graphite products are at least within 2000 degrees. This is because carbon must be graphite at a high temperature natural environment of 2000-3300 degrees at a high temperature and natural environment of at least 10 days and

What role does flake graphite play in our lives

Graphite is divided into two types: natural graphite; The second is artificial graphite. Although with the improvement of manufacturing technology, the function of artificial graphite is no less than that of natural graphite in many cases, natural graphite has always maintained its unique advantages in some fields.Among natural graphite resources, flake graphite (crystalline graphite) has low reserves and high value. It has good conductivity, thermal conductivity, lubrication, and oxidation resistance, and is widely used in industries such as metallurgy, machinery, chemical engineering, refractory materials, aerospace, etc. It is one of the indispensable non-metallic materials for the development of high-tech today.Natural flake graphite peelingThe flake graphite structure is flaky and has good surface properties, making it one of the best floatable minerals in nature. According to the size of the scales, flake graphite can be divided into large flake graphite (with particle sizes of

Let's take a look at the uses of battery specific graphite in industrial applications

The special graphite for batteries has good chemical stability, and the specially treated graphite has the characteristics of corrosion resistance, good thermal conductivity, and low permeability, so it is widely used to make heat exchangers, reaction tanks, condensers, combustion towers, absorption towers, coolers, heaters, filters, and pumps, and is widely used in petrochemical, hydrometallurgy, acid-base production, Synthetic fiber, paper making and other industrial sectors, Can save a large amount of metal materials.It is a material for casting, casting, pressing and high-temperature metallurgy. Because of its low coefficient of thermal expansion of graphite and its resistance to rapid cooling and heating, it can be used as a mold for glassware. After graphite is used, Ferrous can be used to obtain castings with accurate size, smooth surface and high yield, which can be used without machining or slightly processing, saving a lot of metal. In the powder metallurgy process of produc

Optical and mechanical properties of graphene

Graphene has excellent optical properties, with an absorption rate of about 2.3% over a wide wavelength range, making it almost transparent. Within the thickness range of several layers of graphene, with each increase in thickness, the absorption rate increases by 2.3%. Large area graphene films also have excellent optical properties, and their optical properties change wi

The Function and Conditions of Adhesive

Carbon graphite material is a powder structure material similar to refractory materials and concrete. Except for non-ferrous brushes and mechanical metal graphite products, which are formed as a whole with a certain strength by phase transformation of metal powder at sintering temperature, the powder particles of typical carbon graphite materials cannot spontaneously bond together even at high temperatures. In order for them to bond into a whole with a certain shape and strength, a certain amount of substance that can bond carbon powder particles or fibrous fine substances into a whole must be added, and this substance is called a binder.The conditions that the adhesive should meet:1) The adhesive should be able to mix with the main material to form a plastic substance.2) The binder becomes a viscous liquid within an appropriate temperature range. And it can have good adhesion and adsorption with the particles of the main material, and has a large adsorption force.3) The binder should

What is the role of scales when galgling?

The application of scales graphite is widely used in industries. Mulchogenic sand is one of the applications of them. Cover sand refers to the sand or core sand with a solid resin film on the surface of the sand grain. In the middle, scales need to be used. Today, I will explain what the scales have the functions when gog graphic is covered with membrane sand:The scaled graphite is used as a lubricant in the lubricant in the sandy sand. The littering of the luster sand can play a lubrication and high temperature resistant role in the sandwich sand. For the requirements of scales with scales in gifsta, it is required to be lubricated as a lubricant and high melting point, and the littering of the lubrication is a natural scale graphite with good lubrication. Carbon content. The melting point of the scale graphite itself is very high. After the production process processing, the high temperature resistance of scales graphite with scales with scales will be higher, and the lubrication ef

Optical and mechanical properties of graphene

Graphene has excellent optical properties, with an absorption rate of about 2.3% over a wide wavelength range, making it almost transparent. Within the thickness range of several layers of graphene, with each increase in thickness, the absorption rate increases by 2.3%. Large area graphene films also have excellent optical properties, and their optical properties change with the thickness of graphene. This is an unusual low energy electronic structure possessed by single-layer graphene. At room temperature, a voltage is applied to a double-gate double-layer graphene field-effect transistor, and the bandgap of graphene can be adjusted between 0 and 0.25 eV. When a magnetic field is applied, the optical response of graphene nanoribbons can be tuned to the terahertz range.When the intensity of the incident light exceeds a certain critical value, graphene's absorption reaches saturation. These characteristics allow graphene to be used as a passive mode-locked laser. This unique absorption

What are the characteristics of the thermal stability of the film -shaped graphite

Sheet -shaped graphite is a natural ore, with a thin piece or scale, and the aggregate is in the form of soil. It is a hidden crystal. Film graphite has many high -quality physical and chemical characteristics, including good thermal stability. Compared with other products, the thermal stability of film -like graphite has great advantages.Film graphite is one of the most high -temperature -resistant materials at present. Generally, the strength of the material is gradually decreased at high temperature. However, when heating to 2,000 degrees Celsius, the strength of the sheet -shaped graphite is twice the temperature at room temperature.Sheet -shaped graphite has excellent heat shock resistance. When the temperature suddenly changes, the thermal expansion coefficient is small, so it has good thermal stability. When the temperature changes rapidly, cracks will not occur.Sheet -shaped graphite is a material with excellent thermal shock. For graphite electrodes used in electric furnace s
