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

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

Introduction to carbon elements

Carbon is a very common element that exists in the atmosphere and crust in many forms. Carbon monouples have been recognized and used for a long time. A series of carbon compounds -organic matter is the foundation of life. Carbon is one of the ingredients of raw iron, cooked iron and steel. Carbon can form a large number of compounds in chemical self -combination, which is an important molecule in biology and business. Most molecules in organisms contain carbon.Existing formThe form of carbon existence is diverse, including crystalline single -quality carbon such as diamond and pulse graphite; there are fordless carbon and coal; there are complex organic compounds such as animals and plants; carbonate such as marble. The physical and chemical properties of single carbon depend on its crystal structure. High -hardness diamond and soft and smooth pulse graphite crystal structures are different, each with its own appearance, density, melting point, etc.CharacteristicsThe chemical propert

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. Expansion of the swelling temperature at height: The starting expansion temperature is 290-300 ° C, and the expansion volume is ≥230ml/g. This type of expansion graphi
