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.

Mold graphite

The casting industry in the mechanical industry uses graphite materials as molds such as pressure casting, centrifugal casting, and hot squeeze of super hard alloy. It can use graphite molds as large as train wheels and small as small as precision parts. Graphite molds can be repeatedly used for multiple times. After the molding, the casting has a high degree of smoothness, and some can be used without further processing. The graphite material used for casting molds should be graphite with a dense texture, low thermal expansion coefficient, and good antioxidant performance. Graphite, which is used for casting with large casting size, can be composed of thicker particle size. It is used for casting small precision parts The graphite must be graphite with fine particles. The number of graphite used to make molds in China is large. In 2005, it was continuously cast about 1500T with graphite and sintering molds were estimated to cost 4000T. Table 4 is the specifications and technical perf

What are the steps of carbon felt purification?

Carbon felt is a major element in many alloy products, so carbon felt purification plays an important role in alloy production. Meanwhile, in the smelting process of metal silicon, silica, ore, etc. are usually used. Silicon slag will also be produced during the smelting process, and silicon slag also contains a certain amount of industrial carbon felt, so we can use carbon felt slag to further purify carbon felt.The first step is to separate the obvious light-colored slag and dark-colored slag from the silicon slag with a manual hammer, and then use the separation principle to further separate the silicon content in the silicon slag.Impurities in silicon slag exist in two forms: reduced and unreduced. In industrial silicon, a flocculant composed of Na2O5~50%, SiO250~95% or Na2O5~50%, SiO250~95%, MgO and CaO is added to industrial silicon. With 35% flux, the melting point of the slag can be reduced from the original 1450 to about 1480 and then down to about 1000. It can also reduce th

What are the advantages of high-purity graphite?

The application fields of high-purity graphite include metallurgy, military, light industry, electrical battery industry, and fertilizer. Can it be called high-purity graphite? In order to make more people familiar with it, here are some related knowledge points about high-purity graphite for everyone? I hope you can bring some better help when choosing in the future.High purity graphite is widely used in fields such as metallurgy, machinery, environmental protection, chemical industry, electronics, medicine, military industry, and aerospace. It has high purity and high strength graphite properties. In fact, the existence of graphite flakes now makes graphite have excellent lubricity. Generally speaking, the larger the ordinary graphite flakes, the better their lubricity. When we use it, we need everyone to know that the graphite industry technology is still at a relatively low level in the world, and the products are mainly raw materials and initial processing products. Therefore, th

Introduce the use of silicon carbide

Silicon carbide has a wide range of uses in industry. Silicon carbide has high hardness and good thermal conductivity. It is a semiconductor that resists oxidation at high temperatures. Although it has many uses, it is not clear to those who have not been exposed to it.1. Application in non-ferrous metal smelting industryThe use of silicon carbide has the advantages of high temperature resistance, high strength, good thermal conductivity, and impact resistance. It is used as a high-temperature indirect heating material, such as solid tank distillation furnaces, rectifier furnaces, aluminum electrolytic cells, copper melting furnace linings, and zinc powder furnaces. Use arc plates, thermocouple protection tubes, etc.2. Application in steel industryTaking advantage of the corrosion resistance, thermal shock resistance, wear resistance, and good thermal conductivity of silicon carbide, it is used in the lining of large blast furnaces to increase the service life.3.

Industrialization process of battery specific Graphene lithium battery

1. Cost issuesThe cost of using Graphene as a conductive agent is much higher than that of ordinary carbon black. The cost of lithium battery is the key control factor. Without reducing the cost of raw materials, even if the electrical performance of Graphene is no better, battery manufacturers can not afford to consume hundreds of thousands of dollars per ton.2. Process issuesThe technical problems caused by the sheet structure of Graphene for batteries are mainly the preparation of electrode paste. The electrode paste requires good fluidity, dispersibility and proper viscosity. The dispersion of Graphene sheets in the electrode paste is a problem, especially the electrode paste cannot be dispersed by adding dispersants. Graphene has a large surface area, which has a great impact on the stability of the slurry settlement, cannot guarantee the consistency of each batch, and affects the battery performance.3. Other factorsThe lamellar structure of Graphene for batteries inhibits the di

Graphite powder from graphite manufacturers is a widely used industrial material

Graphite powder produced by graphite manufacturers is a widely used industrial material, obtained by crushing, grinding, and screening high-purity graphite through rolling. The key to the type of graphite powder is the particle size, which varies from 50 to 30000 mesh. The more mesh the screen, the finer the particle size, and the higher the price. Previously, our country's technological strength could not be reached, and high-end graphite powder had to rely on imports. However, at present, Chinese manufacturing enterprises have introduced cutting-edge overseas powder mills, which can produce and manufacture fine graphite powder with global particle size, and have been used in many industries both domestically and internationally.Graphite manufacturers offer various types of graphite powder, including lubricating graphite powder, conductive graphite powder, nanotechnology graphite powder, high-purity graphite powder, and graphite powder screens with a mesh size of 150, 425, 1000, 3000

The characteristics of silicon graphite

High hardnessThe hardness of silicon graphite is actually the hardness of SIC. It is second only to diamond, boron nitride, boron boronized, and has high hardness than tungsten tungsten and tritenuxide.Excellent corrosion resistanceSIC is a compound of a combination of covalent bonds. The chemical performance is stable. Except for strong oxidized gases and melting alkali, it is almost not eroded by other acid and alkali.Good high temperature antioxidantSICs with dense SI island glass phase at high temperature to prevent oxygen and SIC from contacting and prevent silicon carbide from continuing to oxidize. Therefore, SIC can be used above 1000 ° C for a long time.Excellent heat shocksSilicon fossils are heated to 1200 ° C for 10s, and they are put into room temperature water. It repeatedly repeatedly, as well as before, neither rupture nor peeling.
