Advantages and disadvantages of graphite purification methods

Flotation method is one of the conventional mineral purification methods that consumes the least energy and reagents, and has the lowest cost. This is the biggest advantage of 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) Alkali acid purification method. The carbon content of graphite purified by alkaline acid method can reach over 99%, which has the characteristics of low one-time investment, high product grade, and strong process adaptability. Moreover, it also has the advantages of conventional equipment and stro

Graphite powder is a very widely used industrial material

Graphite manufacturer's graphite powder is a very widely used industrial material. It is obtained by crushing and grinding through high -purity graphite. After screening, the type of graphite powder is key basis. The more the number of sieve networks, the thinner the particle size, the higher the price. In the past, the technical strength of our country could not be achieved, and high -end graphite powder depends on imports. However, at this stage, Chinese manufacturing companies have introduced overseas cutting -edge powder and grinding machines to produce fine graphite powder around the world. EssenceGraphite manufacturers' various graphite powder, moisturizing graphite powder, conductive graphite powder, nano -technology graphite powder, high pure graphite powder, graphite sieve nets are: 150 mesh, 425 mesh, 1000 mesh, 3000 mesh, 5000 mesh, 5000 mesh, 5000 mesh, 5000 mesh, 5000 mesh, 5000 mesh, 5000 mesh, 5000 mesh, 5000 mesh, 5000 mesh, 6500 mesh, 12500 mesh, 15000 mesh, etc. The

The key features of graphite

1. High fever and conduction: In response to the use of raw materials such as graphite with high thermal conductivity, it reduces the time of fusion.2. High temperature resistance: high -temperature resistance has strong impact characteristics, for rapid cold and hot heat, not easy to crack.3. High temperature resistance: high fire resistance, high temperature to 1200 to 1600 ° C.4. Anti -corrosion resistance: strong adhesion to resist melting soup.5. Anti -reflective impact: have a certain anti -reflective impact resistance (when the funds of the melt material are invested, etc.).6. Antioxidant: Graphite is very easy to oxidize at high temperatures in oxidation. Due to the development of oxidation solution, oxidation consumption is less.7. Anti -adhesion: Because graphite is not easy to stick to the soup, the molten soup is soaked and attached with less adhesion.8. There is very little environmental pollution of metal materials: Because there is no bad matter that infiltrate the envi

What is graphite

Graphite is a kind of homogenous alien body for carbon. It is gray -black, opaque solid, stable chemical properties, corrosion resistance, and it is not easy to react with drugs such as acid and alkali. Natural graphite comes from graphite ore. It can also be used as a raw material for oil coke, asphalt coke, etc., and made a series of processes to make a human -made graphite. Graphite is burned in oxygen to generate carbon dioxide, which can be oxidized by strong oxidant such as concentric acid and potassium permanganate. It can be used as an anti -wear agent and lubricant. High -purity graphite is used as a neutron decelerator in the atomic reactor. It can also be used to manufacture crickets, electrodes, brushes, dry batteries, graphite fibers, heat exchangers, coolers, arc furnaces, and arc

What is the use of graphite powder in industry

Because of the characteristics of graphite powder, graphite manufacturers introduced that graphite powder was widely used in industrial applications such as chemical factory, crude oil, metallurgy industry, forging, moisturizing, and sealing. Let's follow the graphite manufacturers to find out what the graphite powder is in the industry:Graphn powder has strong conductivity and heat transfer, high melting point, good lubrication, ductility and chemical resistance. Graphn powder can accept erosion such as strong acid and strong alkali, organic solution, etc.Graphite powder can be used as a guidance raw material to manufacture electrical, carbon brush, carbon tube, carbon stick, TV image pipe coating, etc. in the electrical equipment industry. Graphite powder can be used as refractory insulation materials, and can be used as a protective film for casting and ironmaking as a protective film for cast steel.Graphite can be used as lubricating materials and make lubricating fluid in mechani

The Properties of Graphite and Its Application in Smelting

Graphite undergoes special forming methods to achieve its industrial application characteristics, namely special graphite. The three high graphite is commonly known as the three high graphite in the industry, but not all three high graphite is isostatic pressure graphite. In addition, there are materials such as molded and extruded graphite, which, due to their special structure, have high temperature resistance, conductivity, thermal conductivity, lubrication, chemical stability, and plasticity Characteristics such as thermal shock resistance.The application of graphite in the metallurgical industry is due to its high temperature resistance, thermal conductivity, stable chemical properties, and thermal shock resistance. In the metallurgical industry, graphite is mainly used as a refractory material. We are familiar with graphite crucibles, refractory bricks, and casting molds in the metallurgical industry. Graphite products are closely related to the smelting industry, and in the ste

Precautions for using flake graphite?

Flake graphite is a natural crystalline graphite that resembles fish scales and belongs to the hexagonal crystal system with a layered structure. Therefore, it still has good properties such as high temperature resistance, conductivity, thermal conductivity, lubrication, plasticity, and acid and alkali resistance. Below are some precautions for using flake graphite?Flake graphite is a widely used product in the metallurgical industry for refractory materials and coatings. Such as magnesia carbon bricks, crucibles, etc. Now used as anti-corrosion material. Flake graphite is an anti rust primer made of carbon black, talc powder, and oil, which has good resistance to chemicals and solvents. If chemical pigments such as zinc yellow are added to the formula, its rust prevention effect will be better.

Graphite acid method

The alkaline acid method includes two reaction processes: alkali melting process and acid immersion process. The alkali melting process is to chemically react with the acidic impurities in the molten and graphite under high temperature conditions under high temperature conditions, especially silicon -containing impurities (such as silicate, silicone aluminate, quartz, etc.) to generate soluble salt, and then Remove impurities after washing and improve the purity of
