The use of scales graphite and colloid graphite

Scales graphite is a very widely used non -metallic powder product, with good thermal conductivity, conductivity and lubrication effect; colloid graphite is a graphite product that uses natural scales graphite as the main raw material. There are certain differences in use. The following editor will introduce the purpose of scales graphite and colloid graphite:The scales graphite has a strong conductive capacity. It can replace the metal as a conductive material. The scale graphite can also be directly used as a carbon conductive filler or a composite conductive filler for conductive coating. The quality of scales graphite powder has a lot to do with its carbon content. Natural scales graphite collected from natural mines often contain a lot of impurities. It needs to be purified to get graphite powder with high carbon content because of high purity scales. The use of graphite is more widely used, providing an effective solution for the miniaturization and high integration of electroni

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

Application of scales graphite, come and collect!

Scale graphite is a non -metallic mineral with unique physical chemical properties such as high temperature resistance, antioxidant, corrosion resistance, heat shock, high strength, good toughness, high self -lubricating strength, high heating, and strong conductivity. Graphite series products are mainly used for metallurgy, machinery, electronics, battery, chemical, light industry, military, defense, aerospace, fire -resistant materials and other industries. Scales graphite is an important non -metallic material for modern high -tech.What are the characteristics of scales graphite?

The advantages and disadvantages of high -carbon graphite purification methods

Floating method is a type of energy consumption and reagent consumption in traditional mineral purification methods. This is the advantage of the floating method to purify graphite. However, the use of floating selection and purifying graphite can only achieve limited graphite taste. For scales graphite, multi -level grinding not only can not completely dissolve the monomer, but it is not conducive to protecting large huge graphite. Therefore It is not economical and unscientific. To obtain high carbon graphite with a carbon content of more than 99%, graphite must be purified by chemical methods.(1) Alkaline purification method. The carbon content purified by alkalinic acid method can reach more than 99%, which has the characteristics of less one -time investment, high product quality, and strong process adaptability. It also has the advantages of conventional equipment and strong versatility.(2) hydrogen fluoric acid method. The main advantage of the hydrofluoric acid method is that

Which raw materials are selected for the production of traditional carbon materials

Various metallurgical furnace carbon blocks (such as blast furnace carbon blocks, ferroalloy furnace carbon blocks, calcium carbide furnace carbon blocks, and aluminum electrolysis cell cathode carbon blocks, etc.) are used at a certain high temperature. Therefore, carbon blocks should have high mechanical strength, thermal stability, and corrosion resistance, but the ash content requirements are not too strict. Except for the bottom carbon blocks used in aluminum electrolysis cells, it is not necessary to measure conductivity. The production of carbon blocks mostly uses anthracite as the aggregate and metallurgical coke as the filling material. To improve the thermal conductivity and corrosion resistance of carbon blocks, a certain amount of graphite fragments (or natural graphite) can be added. In order to improve the thermal conductivity and conductivity of carbon blocks, semi graphite carbon blocks can be produced by electrocalcining anthracite.The raw materials used for conductiv

Why add graphite powder to glass fiber?

Glass fiber enhanced plastic (FRP) is a composite composite material based on synthetic resin. It has the advantages of light weight, high strength, corrosion resistance, microwave transmission, electrical insulation, and reasonable performance design according to requirements. It has been widely used in aerospace, petrochemicals, transportation, construction, shipbuilding, machinery, environmental protection, textile and other fields. Glass fiber enhanced plastic (FRP) has good electrical insulation property. Under normal circumstances, the amount of graphite powder is 2.5 ~ 5%, which can reach 30 ~ 50%. So why add graphite powder to glass fiber?From an economic and technological perspective, it is best to choose inorganic abrasive materials, so the amount of graphite powder in the abrasion -resistant material of the glass fiber reinforcement is relatively large. In short, glass fiber wear -resistant materials, because its matrix is a polymer material, fills solid lubricants and vari

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
