- Q: The future of graphene
- Sensor domain. Graphene due to its unique two-dimensional structure is widely used in sensor, has the advantages of small size, large surface area, high sensitivity, fast response time, fast and easy electron transfer protein immobilization and maintained its activity and other characteristics, can improve the performance of sensor. Mainly used in the production of gas, biological molecules, enzymes and DNA electrochemical sensors. Singapore Nanyang Technology University developed a graphene light sensor sensitivity is 1000 times the ordinary sensor; the Rensselaer Polytechnic Institute developed performance than the existing commercial gas sensor cheap graphene sponge sensor.
- Q: Why should the carbon brush for the trolley be made of graphite?
- What you said is the graphite electrode graphite, there may be a high pure graphite graphite conductive rate so high, strong, high density, the graphite is mostly used in motor vehicles, such as generators, and electric tools.
- Q: The reason why graphite is used as electrode
- Graphite is good in plasticity and easier to be machined preciselyGraphite material has the advantages of high processing accuracy and good surface effect, especially in the processing of precise, complex, thin-walled and Gao Ying material mold cavity. Because the cutting resistance of graphite is only 1/5 of copper material, it is easier to do manual grinding and polishing on the operation. There is no burr after graphite processing, and it is easier to realize automatic production. Complex geometric modeling can be realized.
- Q: Specification for graphite electrodes commonly used in steel works
- The variety and specifications of graphite electrodes used in modern EAF steelmaking are mainly determined by the technical parameters of the steelmaking furnace. With the development of EAF steelmaking technology, the steel-making technology is developing towards large scale and ultra high power. The graphite electrode is mainly made of large size graphite electrode and ultra high power graphite electrode.
- Q: Graphite can be used in acid towers in chemical plants because of graphite
- A graphite electrode coated with an antioxidant protective layer (graphite electrode, antioxidant). The utility model has the advantages of forming a protective layer capable of conducting electricity and resisting oxidation at high temperature, reducing electrode consumption (19%~50%) during steelmaking, prolonging the service life of electrodes (22%~60%), and reducing the electric energy consumption of electrodes.
- Q: How much does a graphite electrode cost about a ton?
- According to purity and quality, the price is 1-6 tons / tonDo not calculate the processing cost
- Q: Can Naiduo high temperature graphite
- The reinforced graphite gasket is made of flexible graphite tape or flexible graphite and is molded into ring products of different sizes. Suitable for hot water, high temperature, high pressure steam, heat exchange liquid, nitrogen gas, organic solvent, hydrocarbon, low temperature liquid and other medium. Used in compressors, machines, pumps, valves, chemical instruments, instruments, etc..
- Q: How does graphite produce solar cells?
- In addition, the Research Report of the first author, Massachusetts Institute of Technology Department of materials science and engineering postdoctoral Zhang Shenggen said, different from other semiconductor temperature has been rising continuously, the graphite electrode coating Zinc Oxide nanowires can be temperature controlled at 175 degrees celsius.
- Q: Iron and graphite as electrodes and Nacl as electrolyte solutions. Why do they produce electric current? Graphite and iron react not with solution, can they be connected by wires?
- What happens is oxygen etching negative pole: Fe-2e-=Fe2+ positive electrode: O2+2H2O+4e-=4OH-, of course, the current is produced.
- Q: How can the graphite powder be processed into high quality carburizing agent? Thank you
- Basically, it can no longer be a "good" carburizing agent
