Immersion graphite

Plug -in graphite, also known as immersive graphite or immersion immersion graphite. Category of non -transparent graphite.Immersion graphitePinyin: jinzishimoEnglish name: ImpregNated GraphiteNote: Use synthetic resin to penetrate graphite to fill its surface and internal pores, and then make the heat treatment to curing the resin and make it. Compared with graphite, mechanical strength is improved and thermal conductivity is unchanged. With the difference in penetrating resin, there are different varieties such as phenolic graphite and bran glycoling graphite.

Advantages and disadvantages of high carbon graphite purification methods

The flotation method is one of the conventional mineral purification methods that consumes less energy and reagents, and has a lower cost. This is a major advantage of the flotation method for purifying graphite. However, using flotation to purify graphite can only achieve a limited increase in its grade. For flake graphite, using multi-stage grinding not only cannot completely dissociate its monomer, but also is not conducive to protecting the large scale of graphite. Therefore, using flotation to further improve graphite grade is neither economical nor scientific. To obtain high carbon graphite with a carbon content of over 99%, chemical methods must be used to purify the graphite.（1） Chlorination roasting method. The low roasting temperature and low chlorine consumption of the chlorination roasting method significantly reduce the production cost of graphite. At the same time, the carbon content of graphite products is equivalent to that after treatment with hydrofluoric acid, and t

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

Graphite flotation method

Floating is a commonly used and important mineral method. Graphite has good natural floating. Basically, all graphite can be purified by floating methods. In order to protect graphite scales, most of the graphite flotation uses multiple sections of processes. Graphite flotation collecting agents are generally used for kerosene, with a dosage of 100 to 200g/t. The foaming agent is generally used with pine or butad ether, and the amount is 50 to 250g/t.

Cast iron graphite

The formation process of graphite in cast iron is called graphization process. The basic process formed by cast iron tissue is the formation of graphite in cast iron.The graphite type and size of the gray cast iron depends on the graphite branches and growth rate in the common crystal group. When the common crystal group stops growing, the graphite will stop. They are separated and not connected. Using scanning electron microscope to observe the complete graphite in the common crystal groupThe three -dimensional form indicates that they are connected to each other. Only on the gold phase grinding surface is isolated.The national standard has the following divisions of the graphics of cast iron graphite: type A fine sheet, B -shaped flower shape, C -shaped thick blockbuster, D -shaped dot, E has directional points, f spider -like or planetary. The longest (100 times, greater than 100mm is 100mm. It is called 100mm long). The shortest graphite is the shortest (100 times at 100 times, le

How to use expansion graphite

1. Protective useExpansion graphite can be used as protective materials, which can be used to protect metal and other damaged objects, such as circuit boards and steel. Because expansion graphite can expand 10 times, it can effectively block the flames and make these objects from burning with flames.2. InsulationExpansion graphite can also be used as insulation materials, because it has good thermal resistance and can effectively block heat, so it can be used for insulation, such as electronic products. It can also be used for cooling, preventing the loss of heat, thereby playing the role of heat preservation.3. Filtering useExpansion graphite can also be used as filtering materials, because it has adsorption and can be used to adsorb toxic substances, such as pollutants used in water treatment, which can effectively remove pollutants in water. It can also be used for air purification to block the entry of harmful substances.4. Reinforcement useExpansion graphite can also be used as r

Maintenance and upkeep of graphite crucibles

The graphite crucible must be strictly protected from moisture and must be stored in a dry place or on a wooden frame. When handling graphite crucibles, it is important to handle them with care and prevent them from falling or shaking. Before using them, they should be baked in a drying equipment or by the furnace to raise the temperature to 500 ℃. The graphite crucible should be placed below the surface of the furnace mouth to prevent wear and tear on the furnace cover. When adding materials, it should be based on the solubility of the crucible, and too much material should not be added to prevent tightening the crucible. The furnace outlet and crucible clamp should conform to the shape of the crucible, and the clamp in the middle should prevent damage to the crucible due to stress on the department. When removing slag and coke from the inner and outer walls of the crucible, it should be gently knocked to prevent damage to the crucible. A suitable distance should be maintained betwee
