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

Material characteristics of graphite powder

Graphite powder is a substance that is very sensitive to chemical reactions. In different environments, its resistivity will change, which means its resistance value will change. However, there is one thing that does not change. Graphite powder is one of the good non-metallic conductive substances. As long as the graphite powder is kept uninterrupted in an insulated object, it will also be electrified like a thin wire. However, there is no accurate number for the resistance value, Because the thickness of graphite powder varies, the resistance value of graphite powder will also vary when used in different materials and environments. Due to its special structure, graphite has the following special properties:1) High temperature resistant type: The melting point of graphite 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 te

The purpose and function of graphitization

Graphitization is a high-temperature heat treatment process in which the roasted product is placed in a high-temperature furnace and heated to a temperature above 2300-2500 ℃ in a protective medium, transforming the hexagonal carbon atom plane grid from a two-dimensional disordered arrangement to a three-dimensional ordered graphite structure.Its purpose and function are:1. Improve the thermal and conductive properties of materials;2. Improve the thermal stability, thermal shock resistance, and chemical stability of materials;3. Improve the lubrication and wear resistance of materials;4. Remove impurities from the material and improve purity;5. Reduce the hardness of the material to facilitate mechanical processing.

Factors affecting the impregnation effect

The factors that affect the impregnation effect include: firstly, the impregnation process conditions (such as temperature and pressure), and secondly, the physicochemical properties of the impregnation.Influence of process conditions(1) Temperature (product preheating temperature, impregnation tank temperature, impregnation agent temperature), depending on the impregnation process: 1. The product is preheated too high and is prone to oxidation; The temperature is too low, and when it comes out of the preheating box, it quickly cools down and enters the impregnation tank. When the impregnating agent encounters cold products, its viscosity increases and its fluidity deteriorates, resulting in poor impregnation effect. 2. If the tank temperature is too high, asphalt is prone to oxidation condensation reaction, viscosity will also increase, and flowability will deteriorate; The tank temperature is too low, the fluidity of asphalt is also poor, and the impregnation effect is not ideal.(2)

Brief Introduction to the Use Technology of Graphite Electrodes

1. Varieties of graphite electrodesElectric arc steelmaking furnaces are generally divided into three categories, namely ordinary power electric furnaces, high-power electric furnaces, and ultra-high power electric furnaces. Corresponding to the power level of electric furnace steelmaking, graphite electrodes are also divided into three types, namely ordinary power graphite electrodes (code RP level), high-power graphite electrodes (code HP level), and ultra-high power graphite electrodes (code UHP level). The nominal diameter of the electrode ranges from 75mm to 700mm. The physical and chemical properties of high-power and ultra-high-power graphite electrodes are superior to ordinary power graphite electrodes, such as low resistivity, high bulk density, high mechanical strength, low linear expansion coefficient, and excellent antioxidant performance. The physical properties of three types of graphite electrodes are shown in Table 1.Selection of graphite electrodes for AC arc steelmak

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

Characteristics of Mechanical Processing of Carbon Materials

(1) The organizational structure of carbon materials is formed by the preparation of carbon solid aggregate particles and powder raw materials through a series of production processes, so its cutting is composed of a certain number of particles and dust. The large amount of carbon dust generated during the cutting process not only pollutes the operating environment and affects the health of operators, but also the silicon carbide impurities contained in graphite dust can cause certain wear and tear on machine tool components. Therefore, efficient ventilation and dust removal equipment must be installed in the mechanical processing workshop of carbon materials.(2) Carbon material is a heterogeneous and brittle material, with a considerable range of hardness fluctuations. Roasted carbon products have a high hardness, which makes processing more difficult. Graphite products have a low hardness, making them easy to cut and process. The surface roughness of products processed with carbon m

Electronic effect of graphene

Graphene already exists in nature, but it is difficult to peel off a single layer structure. Graphene is stacked layer by layer to form graphite, with a thickness of 1 millimeter containing approximately 3 million layers of graphene. A pencil lightly scratches on paper, leaving traces that may be several or even just one layer of graphene.
