Two ways of formation of scales graphite

The application of scales graphite in the industry is very widely used, and it plays a pivotal role. my country is one of the countries with rich scales in the world in the world. So how does the scales graphite ore formed? Two causes of biology, the following editors will explain the two formation methods of scales graphite for everyone:1. Bio -graphite biological causesBiological causes refer to the scales graphite directly from organic matter, commonly in marble, sliced rocks, or hemp rocks. Coal seams or carbon -containing sedimentary rocks can form scales graphite. It is the metamorphic mineral of graphite, which is made of organic or charcoal.Second, the non -biological cause of graphiteNon -biological causes refer to the reducing carbon out of CO and CO2. In the contact zone between magma rocks and limestone, scales are often produced. This is due to the decomposition of carbon dioxide by limestone and degenerate. The formation of mineral beds must concentrate and have suitable

Pure method of high -carbon graphite

The flotation method is a type of energy consumption and reagent consumption and low cost in the conventional purification method of minerals. This is the advantage of the floating method purification method. For scales -shaped graphite, multi -segment mills cannot be completely unbuttoned, but they are not conducive to protecting large scales of graphite. Therefore, the use of flotal methods to further improve the graphite taste. High carbon graphite containing more than 99%of carbon must use chemical methods to use graphite.(1) Pure method of alkaline acid. The carbon content after the purity method of alkaline acid method can reach more than 99%, which has the characteristics of less one -time investment, high product quality, and strong process adaptability. The purity of metal mines can adopt the advantages of alkaline acid method). The alkaline acid method is a wide range of methods in my country today; its disadvantages are large energy consumption, long response time, large gr

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.

Knowledge points related to flake graphite

As a functional filler for coatings, flake graphite is mainly used for anti-corrosion coatings, fireproof coatings, and conductive coatings. As an anti-corrosion material, it is a rust resistant primer made of carbon black, talc powder, and oil, which has good chemical resistance and solvent corrosion resistance. If chemical pigments such as zinc yellow are added to the formula, the rust prevention effect will be better.In lithium-ion battery materials, anode materials are the key to determining battery performance. As a high crystallinity graphite material, the particle size of flake graphite directly affects the specific surface area of the electrode and the proportion of edge carbon atoms, which has a significant impact on the irreversible specific capacity of electricity. Therefore, flake graphite plays a crucial role in batteries.Flake graphite is one of the important materials for lithium batteries due to its high electronic conductivity, large lithium ion diffusion coefficient,

The Electronic Effect of Graphene

Graphene already exists in nature, but it is difficult to peel off a single layer structure. Graphene is stacked layer by layer to form graphite, with a thickness of 1 millimeter containing approximately 3 million layers of graphene. A pencil lightly scratches on paper, leaving traces that may be several or even just one layer of graphene.The carrier mobility of graphene at room temperature is about 15000 cm2/(V · s), which is more than 10 times that of silicon material and more than twice that of the known material indium antimonide (InSb) with the highest carrier mobility. Under certain specific conditions, such as low temperature, the carrier mobility of graphene can even reach up to 250000 cm2/(V · s). Unlike many materials, the electron mobility of graphene is less affected by temperature changes. At any temperature between 50 and 500K, the electron mobility of single-layer graphene is around 15000 cm2/(V · s).In addition, the semi integer quantum Hall effect of electron carriers

Classification of graphite blocks

Classification of graphite blocks of graphite block classification of graphite blocksThe crushing of graphite blocks can be divided into three items, do you know?Pre -fragmentation (or crushing): This also refers to the crushing of block -shaped graphite block raw materials after entering the factory. Generally, it refers to crushing the block of the block of 200mm to 50 ~ 70mm.Middle crushing: This also refers to the granular block of graphite blocks that is further broken until the granularity necessary for the seasoning. Generally, the block degree of up and down 50mm after the forging is crushed to 1 ~ 20mm.Essence (or grinding): It is the following powders to grind some graphite raw materials to 0.15mm or 0.075mm particle size. Every time it goes through, the granularity of the raw materials has become smaller. The larger diameter of the large raw material before crushing is the ratio of the diameter of the larger block of the raw material after crushing, which is called a crushi

What are the effects of graphite products?

What are the effects of graphite products? The scope of graphite applicable is to produce artworks that can manufacture fire insulation materials and high -temperature raw materials. In recent years, fire prevention insulation and insulation materials have not been widely used in industrialized production. So what are the efficacy of graphite products? Beijing graphite pot manufacturers summarize the scope and efficacy of graphite products.Industries such as national defense and safety have been widely used, and graphite products have long been widely used in metallurgical industry, chemical enterprises, petrochemical equipment machinery equipment, high -energy physics, aerospace, electronic components, etc. High -purity graphite can be used to manufacture insulation bricks, tongs, constantly built -in powder, molding cores, mold casting, detergent and high temperature resistance, which is closely linked to the steelmaking industry.

How to maintain graphite processing into graphite stick products?

1. During the use of graphite stick products, the graphite stick products are turned once a week to extend the life of graphite stick products;2. Using an appropriate amount of combustion agent, additives will reduce the life of graphite sticks;3. Keep a proper distance between the graphite stick and the wall of the furnace, and the graphite stick products should be placed in the furnace positive;4. When removing the inside of the graphite rod product, the inside of the wall of the graphite and sticking should be tapped to prevent damage to damaging graphite rod products;5. Graphite products are strictly preventing humidity. They must be placed on a dry place or wooden stand during storage.

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.
