Q: What is special graphite powder used in graphene?: Graphene special graphite powder is specially used for the development of graphene, graphene graphene from graphite powder is special in stripping out, universities and research institutions of graphene special graphite powder, graphite powder, graphene special quality of Qingdao Huatai provide very good, have a good reputation among colleges and universities, scientific research institutions in such help, hope to adopt L.

Q: How can the clinker graphite powder be dissolved in water?: To achieve this purpose many methods; the titanate coupling agent and silane coupling agent is used in simple water dispersion system of the surface modification, hydrophilic group will make Shi Mofen (film) dispersed in water while stirring under shear stress.

Q: Use of carburizing agents: In the smelting process, due to improper ingredients or improper loading and excessive decarburization, the carbon content in the steel sometimes does not meet the requirements of the top stage. The commonly used carburizing agents include carburized pig iron, electrode powder, petroleum coke powder, charcoal powder and coke powder. When smelting medium and high carbon steel in converter, the oil containing little impurity is used, and Jiaozuo is used as carburizing agent. For BOF steelmaking using recarburizer requirement is high to low fixed carbon, ash, volatile matter and sulfur, phosphorus, nitrogen and other impurities, and dry, clean, moderate size.

Q: Can graphite be made directly from graphite powder? How about the effect?: Let the graphite powder stick into shape. The commonly used asphalt in the industry is used as binder, and graphite powder and asphalt are mixed and pressed to form. It is also necessary to heat, roast and graphitized the asphalt in the graphite blocks to obtain certain heat conducting, conductive or other uses of Shi Mobang.

Q: What graphite powder made of graphite products, high hardness?! Wear-resisting！ Good moisture! It can be made into graphite products at 100-200 degrees high temperature: 100~200 C is not called high temperature for the preparation of carbon graphite products, but only resin can be prepared at this temperature.

Q: Like the wolf, adding graphite powder in the failure of electronic instrument air explosion in aircraft rocket season, really make it: The graphite bomb is real, but the main is to destroy the enemy power plant and other fixed objects, the damaged helicopter is unlikely, because the rocket explosion scope is limited, that not what eggs with graphite. It's better to use a bullet warhead than a graphite warhead.

Q: Are graphite powders soluble in water, dilute acids, dilute bases, and organic solvents?: Under heating, the graphite powder is more easily oxidized by acid. At high temperature, it can react with many metals to produce metal carbides, which can smelt metals at high temperature

Q: Know how the colloidal graphite powder comes in: There are two ways to make colloidal graphite: (1) mechanical method. Natural graphite is crushed and treated with hydrochloric acid and hydrofluoric acid to remove impurities. Added to the aqueous solution of tannic acid, which is repeatedly inverted into paste. Colloidal graphite can be obtained by adding a certain proportion of water and ammonia, and then by ultrasonic treatment to further reduce the particle size. (2) chemical method. After being purified and crushed, the natural graphite is added with concentrated nitric acid and concentrated sulfuric acid and water at 90 DEG C, and then obtained by cleaning, drying, adding water, ethanol, acetone and other dispersing agents to obtain colloidal graphite. Add stabilizer such as sodium oleate, sulfate and so on, so that graphite particles do not agglomerate. Ammonia transfers the graphite colloid to the gum solution and regulates the pH value.

Q: The axis and drum can use graphite powder lubrication: This doesn't seem good. Graphite powder is a solid lubricant. It is suitable for heavy equipment lubrication. The axis and drum or low viscosity lubricating grease is better, so fast.

Q: Does the graphite powder cause explosion? If so, how to prevent the production of graphite products in the workshop?: Flammable dust is suspended in the air at an appropriate concentration to form dust clouds that are commonly called;All the solid matter which is fine powder is called dust. The dust that burns and explodes is called combustible dust; the dust floating in the air is called suspended dust; the dust deposited on the solid wall is called sedimentary dust.With explosive dust: metal (such as magnesium, aluminum); coal; grain (such as wheat, starch); feed (such as blood meal, fish meal); agricultural and sideline products (such as cotton and tobacco); forest products (such as paper powder, wood flour); synthetic materials (such as plastics, dyes).
