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.

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

Graphite physicss

The chemical properties of single -mass carbon at room temperature are relatively stable, insoluble in water, dilute acid, dilute alkali and organic solvents; burning with oxygen at different high temperatures to generate carbon dioxide or carbon dioxide; Below, single -quality carbon is more likely to be oxidized by acid; at high temperature, carbon can also react with many metals to generate metal carbides. Carbon is restored and can smell metal at high temperature.Graphite is soft, black and gray; it is greasy and can contaminate paper. The hardness is 1-2, and the hardness can be increased to 3 to 5 along the vertical direction. The proportion is 1.9 ～ 2.3. The surface area is concentrated at 1-20m2/g. Under the isolation of oxygen conditions, its melting point is above 3000 ° C. It is one of the most temperature-resistant minerals. It can conduct electricity and heat conduction.There is no pure graphite in nature, which often contains impurities such as SIO2, Al2O3, Feo, CAO, P2O

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 application of scales graphite in rust protection

Scale graphite should be no stranger. The scales graphite is very wide, such as lubrication, conductivity, etc. So what are the applications of scales graphite in rust?Apply the scales graphite on a solid and then put it in the water. We will find that the solids that have been applied by the scales will not be wet by the water. Even if it is soaked in water, it will not be wet. The layer protective film is separated from the water from water, which is enough to indicate that the scale graphite is not soluble in water. Using the characteristics of graphite can be used as a good rust -proof paint, coated with metal chimneys, roofs, bridges, pipes, and can effectively protect the metal surface from corrosion of atmosphere and seawater, and has good anticorrosive rust and anti -anti -rust performance.This situation is often encountered in life. The connection bolt or steam pipe flange of the cleaning equipment is very easy to rust, which brings great trouble to maintenance and disassembl

Application of Graphene

Graphene makes indoor people feel like they are in a windless "warm winter sun", with both heating and health care. Unlike traditional heating equipment such as air conditioners, oil heaters, and underfloor heaters, graphene heating paintings are more comfortable, energy-efficient, non boring, noiseless, neither oxygen deficient nor light pollution, and are a classic masterpiece of technological change.In addition to covering and insulating the body, traditional clothing only has value left, and there are few high-tech products that appear. Through skill discussions, medical expert Zhiren has independently developed high-tech intelligent heating clothing in the application field of graphene electric heating film, targeting extremely cold areas, outdoor people in winter and spring, people with weak physique, and people who love beauty in winter.

The purpose of graphite machining

Various carbon graphite products, although they have a certain shape and size after forming, undergo expansion and contraction, deformation and bending, collision or corner dropping during the process of roasting, impregnation, and graphitization treatment from the pressed blank to the graphitized blank. The surface adheres to some fillers and insulation materials, resulting in roughness and unevenness. Their shape and size change to a certain extent, and they cannot achieve the shape of the product during use, Due to strict requirements for size and surface roughness, it cannot be used without mechanical processing. In addition, some products have complex structures and shapes that cannot be directly produced by forming methods, such as metal continuous casting and rolling graphite crystallizers, electric spark machining graphite molds, carbide sintering graphite boats, discs, and other special graphite products. Some products require interconnection when used, such as the connection

Graphite and cold stack

WatereoledgraphiteModer-Fedreactor with graphite as a slow neutron reactor with graphite as a chronic agent and water as a cooling agent. In the early days of the development of the nuclear industry, graphite and cold stacks were mainly used to produce nuclear weapons installation -钚, 氖, etc. This heap is generally fuel with natural uranium metal components. Uranium 235 in the natural uranium in the pile absorbs neutron reactor in neutron and releases neutron and energy. These neutron parts are used to maintain chain nuclear fissure reactions, and some are absorbed by the uranium 238 in natural uranium and converted into it to converted into it into. 钚 239 and other 素 isotopes. Structural graphite and cold stacks use nuclear pure graphite masonry as a chronic agent and reflective layer. There are two or three thousand horizontal tunnels (horizontal piles) or vertical tunnels (vertical piles) in the graphite masonry. Inserting graphite sleeves in these holes, aluminum alloy crafts pipe
