Popular Science Knowledge of Graphite Crucibles

Crucibles can be divided into three categories: graphite crucibles, clay crucibles, and metal material crucibles. In graphite crucibles, there are three types: regular graphite crucibles, irregular graphite crucibles, and high-purity graphite crucibles. Various types of graphite crucibles differ in performance, main uses, and application standards, resulting in differences in commonly used raw materials, production methods, production processes, and product specifications and models.The main raw material of graphite crucible is pure natural graphite in crystalline form. Therefore, it maintains the various physical and chemical characteristics of pure natural ink.Namely, it has excellent thermal conductivity and heat resistance, and has a small coefficient of linear expansion throughout the high-temperature application process. It has certain strain resistance performance for rapid heating and quenching. Strong corrosion resistance to acid and alkaline solutions, with high-quality orga

Excellent characteristics of graphite plates

Graphite plate is a good technical property, and its good properties are widely used in various industries. Due to the excellent chemical and physical properties of the product, it has gradually become a key raw material for making grinding tools. Graphite belongs to the raw material of graphite carbon. During the production process, alkaline resistant organic chemical compounds are added, and then subjected to high-pressure manufacturing and forming. After undergoing high-temperature heat treatment, production and processing are carried out, thereby reducing the porosity of graphite products, improving the relative density of products, and possessing good alkali resistance and wear resistance. Graphite plates have high-quality characteristics and are suitable for industries such as forging, metallurgy, and grinding tools. CNC lathe processing machines and equipment further enhance the overall production and manufacturing level, and consider the requirements for precision and surface

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

Skin graphite mineral procurement agent

Scales graphite is a crystalline crystal carbon. It has high electrical and thermal conductivity, high temperature resistance, stable chemical properties, low hardness and slippery. It is easy to adhere to the solid surface and can draw clear dark stripes on the paper. These excellent properties of the mineral selection process and minerals have made it widely used in industry. The following is the scales graphite minerals introduced by scales graphite manufacturers:Graphite ingredients, mining agents are mainly flotal, sometimes shaking sorting. This thin piece uses a static electricity selection method, but because the electrical selection needs to be fully dry and accurate, it is difficult to manage high -voltage power management in a humid environment, difficulty in processing fine particles, and cannot be promoted.In non -metal minerals, graphite is a relatively easy to float mineral. Therefore, scales graphite can only float well with foaming agents (such as pine oil oil, methax

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

Analysis of the scope of application of industrial graphite in graphite products

Graphite products maintain the original chemical properties of flake graphite, namely acid resistance, corrosion resistance and physical properties, namely high temperature resistance 3000C and low temperature resistance 204C. Its compressive strength is greater than 800kg/cm2, and it is anti-oxidation. It loses weight in air at 450°C by 1 % , the rebound rate is 15-50% (density 1.1-1.5). It also has strong self-lubricating properties. Therefore, graphite products have been widely used in metallurgy, chemical industry, petrochemical industry, high energy physics, aerospace, electronics and so on.Using the characteristics of graphite, people have deftly made different types of products according to the needs of engineering: such as high-purity graphite products, flexible graphite products, composite graphite products and so on. In order to improve the performance, graphite and fiber (including synthetic fiber), graphite wire, metal mesh, and metal processing plate are combined to make

Many new main uses of graphite have 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
