Application of graphite cathode carbon block

Carbon blocks made from high-quality anthracite, coke, graphite, etc. Used as a cathode for aluminum electrolysis cells. It is built at the bottom of the electrolytic cell, also known as the bottom carbon block. The characteristic cathode carbon block plays a dual role in conducting electricity and forming the inner lining of the electrolytic cell. Aluminum electrolysis production requires cathode carbon blocks to have high temperature resistance. The characteristics of resistance to molten salt erosion and conductivity, good thermal conductivity, high mechanical strength, good thermal shock resistance, and strong sodium corrosion resistance are conducive to energy conservation and improved cell life in aluminum electrolysis production.Graphite cathode is a conductive material used for the cathode of aluminum electrolysis cells, representing the development direction of the electrolytic aluminum industry. With the technological progress and development of the electrolytic aluminum ind

The black PCB is difficult to see the wiring clearly, which brings difficulties for maintenance

From this point of view, the color of PCB has nothing to do with the quality of PCB. The difference between black PCB and blue PCB, yellow PCB, etc. The difference between PCB is different in the color resistance paint color. If the PCB design and manufacturing process is exactly the same, the color will not have any impact on performance, and it will not have any eff

What are the nature of ultra -fine graphite?

Ultra -fine graphite powder is one of the categories of graphite powder. The raw material of ultra -fine graphite powder is natural scales graphite. The airflow crusher or ultra -fine pieces is used to crush the natural scales graphite. The particle size of ultra -fine graphite powder reaches 6 ~ 10 μm, which is the ultra -fine graphite powder.The preparation process of ultra -fine graphite powder is: natural scales graphite and raw materials focus from compressed air to enter the crushed room by adding feed sprayer, sprayed in the crushing room, spray ultra -high -speed airflow at the crushed room , Fricate into microfimm, with a microfimm airflow, discharge from the exit tube into the hierarchical room, separate the thicker particles, and crushed it again by the rebate tube. Ultra -fine graphite powder was produced.Ultra -fine graphite powder can be widely used in the fields of conductive materials, wear -resistant lubricating materials, atomic energy industry and national defense i

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
