- Q: Can I use super fine stone powder in grease or lubricating oil?
- Yes, it can play a role in increasing extreme pressure. But it has little effect on low temperature and high temperature resistance. It can not play the role of total synthesis of molybdenum disulfide high temperature grease.
- Q: Classification of graphite powders
- High purity sub micron graphite particles have a very wide range of applications: electronic information industry, CRT display manufacturing black conductive coatings, by the use of liquid crystal display device, a sensor and a color decomposition device on the photosensitive black film, flat panel display color liquid crystal color plasma for improving emission effect and part of state color contrast, ultrafine tungsten, molybdenum wire drawing and other senior paint, lubricating oil and grease manufacturing, high performance battery manufacturing and foam iron nickel film is widely used in many industries such as high purity sub micron graphite particles.High pure graphite superfine powder colloidal graphite powder, mainly used in powder metallurgy, pen special, special lubricating oil, lubricating grease, special special batteries special conductive coating, special, special coating, lubrication of defense, scientific research institutions of scientific research, civilian nuclear power, aerospace and special special strategic weapons power interference smoke bomb, shielding, colloidal graphite powder production in China is the development of industry of our country graphite industry pacesetter, part of the technology has reached the international advanced level.
- Q: How does graphite powder look good or bad?
- The graphite powder is soft, black and gray, greasy and polluting paper. Hardness is 1~2, along the vertical direction with the increase of impurities, its hardness can be increased to 3~5. The specific gravity is 1.9 ~ 2.3. Under isolated oxygen conditions, the melting point is above 3000 degrees Celsius and is one of the most refractory minerals. At room temperature, the chemical properties of stone toner are relatively stable, insoluble in water, dilute acid, dilute alkali and organic solvents. The material has high temperature resistance and conductivity, and can be used as refractory materials, conductive materials, wear-resistant and lubricating materials.
- 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: Method for identifying iron powder, aluminium powder and graphite powder
- 1. with a magnet and dilute hydrochloric acid!2. direct use of hydrochloric acid, aluminum powder, gas faster; iron powder moderate; graphite powder does not respond!
- 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: Is oxygen allowed in the oxygen pipe?
- Graphite is a stable substance, and oxygen pipes permit graphite
- Q: Distinguish iron powder and graphite powder by chemical method
- Add dilute sulfuric acid, there is a bubble generated iron powder, the phenomenon is Shi Mofen
- Q: Why does an electromagnetic point timer not prick a needle and use toner paper?
- Needles can increase friction! Will increase the error!
- Q: Does graphite allow lubrication of rusted doors?
- Sure。 When we were young, the teacher reminded us that we could use the pencil core to scrape the end and put it into the keyhole to lubricate it.
