Graphite products conductive material

Graphite is widely used in the electrical industry for electrodes, brushes, carbon rods, carbon pipes, mercury tubes, cashiers, cashmerers, telephone parts, televisions, coatings of televisions, and so on. Among them, the application of graphite electrodes is the most widely used. When smelting various alloy steel and iron alloy, use graphite electrodes. At this time, the powerful current passes through the melting area of the electric furnace to generate an arc, which translates the electric energy to the heat energy, and the temperature is increased to the left and right. So as to achieve the purpose of melting or reaction. In addition, when electrolytic metal magnesium, aluminum, and sodium, the anode of the electrolytic groove also uses graphite electrodes. The resistance furnace that produces rigid sand was also used as a furnace head conductive material with graphite electrode. The graphite used in the electrical industry is high in granularity and taste. For example, alkaline b

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 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. This product is mainly used for flame retardant coatings, and its demand is very large.2.

What should be paid attention to when processing refractory materials with flake graphite?

Several physical and chemical indicators that need to be understood when selecting graphite materials

Graphite is an allotrope of elemental carbon, where each carbon atom is surrounded by three other carbon atoms (arranged in a honeycomb like pattern with multiple hexagons) that are covalently bonded to form covalent molecules. Due to its excellent properties, graphite is used to make many materials. Below are several physical and chemical indicators that need to be understood when selecting graphite materials:1. Average particle diameter of the materialThe average particle diameter of a material directly affects its discharge condition. The smaller the average particle size of the material, the more uniform the discharge of the material, the more stable the discharge condition, and the better the surface quality. For forging and die-casting molds with low surface and precision requirements, it is usually recommended to use materials with coarser particles; For electronic molds with high surface and precision requirements, it is recommended to use an average particle size of 4 μ Mater
