What are the characteristics of high pure scales graphite

High -pure scales graphite has good high temperature resistance, conductivity, high -pure graphite thermal conductivity, lubrication and chemical stability. Graphite manufacturers are widely used in metallurgical, machinery, environmental protection, chemical, fire, electronics, medicine, military, military, aerospace and other fields. Its status in the national economy is becoming more and more important, and it is an indispensable and important non -metal raw material for modern industry and high -tech development. Trace impurities have a great impact on the performance of graphite products. The higher the carbon content of high pure scales, the better its performance as a functional material.In order to analyze the trace impurities in high pure scales, the sample is usually grayed or wet to digest to remove carbon, dissolved ash with acid, and then determined the impurities in the solution. The grayization method does not need to dissolve gray with ultra -pure acid, avoiding the ri

Graphite mold for antioxidant treatment

1. Heating and conductive: The heterogeneity of graphite is 300 times that of the normal non -non -non -metal mine. Conductivity surpasses non -metal materials such as steel, iron, lead. The conductivity coefficient increased with a decrease in measure, and even at a high degree, graphite became armatologist.2. Chemical stability: Graphite is excellent chemical stability at normal temperature, and the erosion of acid, alkali resistance and inorganic solvents.3. Smooth: The smooth function of graphite originated from the size of the graphite scales. The larger the scales, the smaller the conflict coefficient, and the better the smooth function.4. Plasticity: The graphite is tough and can be crushed into a thin crack. 5. Taxation shock: Graphite can be banned violently at the time of normal temperature and can be banned violently without destruction. When the measurement gradually changes, the volume of the graphite is not large and no cracks will occur.6. Low temperature resistance: T

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

The shortcomings and prevention of graphite mold heat treatment process

Several factors of hot pressure graphite mold damage

1. Broken: Graphite mold directly contacts the matrix powder containing diamond. The contact surface is in a high pressure state. The hardness of diamond and graphite mold is too poor. The surface of the mold that is in contact with diamond tool head will produce concave pits.Second, the type of damage: During the sintering process, the matrix powder infiltrates into the oxidation gap of the graphite mold under the melting state, resulting in the adhesion between the tool head and the mold, making it difficult for molding. The repeated attack of the mold can remove the mold, which causes the lack of edges and metal pit in the mold.Third, the wear size of graphite molds is very poor: some substrate powder will be squeezed out of the mold surface in the melting state to attach to the graphite material. Before using the mold next time, metal residues must be removed manually, which causes the shape and size of the mold to exceed the tolerance.Fourth, surface oxidation and cracking: Becau

The production process and use of expansion graphite

The expansion graphite is a loose and porous worm -like substance prepared by the procedure of graphite scales through the intervening, washing, drying, and high temperature. When the expansion graphite encounters high temperature, it can instantly swell 150 ~ 300 times in volume, which changes from sheet to worm -shaped, thereby loose structure, porous and bending, expanded surface area, improved surface can be enhanced. In this way, it increases its softness, return elasticity and plasticity.The expansion graphite is widely used, and the main development directions are as follows:1. Granules expand graphite: Small particles expand graphite mainly refer to 300 purposes that can expand graphite, and its expansion volume is 100ml/g.
