- Q: Classification, uses and manufacturers of graphite electrodes
- Graphite as electrode(1) the processing speed is faster: normally, the mechanical processing speed of graphite can be 2~5 times faster than copper, while the discharge processing speed is 2~3 times faster than copper;More material is not easily deformed: obvious advantages in the processing of thin electrodes; copper softening point at about 1000 degrees, easily deformed by heat; graphite sublimation temperature is 3650 degrees; the thermal expansion coefficient of copper is only 1/30.(2) lighter weight: the density of graphite is only 1/5 of copper. When large electrode is used for discharge machining, it can effectively reduce the burden of machine tools (EDM). It is more suitable for large-scale die applications.
- Q: Which department in the steel plant needs graphite in large quantities?
- 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: What's the use of carbon?
- Common power graphite electrode. Allows the use of current density of less than 17A/ cm 2 graphite electrode, mainly used for steelmaking, smelting silicon, yellow phosphorus and other ordinary power furnace.
- Q: Can graphite be used as an electrode for electrolysis of silver in silver nitrate?
- Xiaoyi Liyang said the principle is correct, but can get silver? I think we can solve the problem if we take proper measures to get the silver elements, such as separating the anode and the cathode from the salt water!
- 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?
- The team at the Massachusetts Institute of Technology has confirmed that electrodes based on graphene and ITO devices are comparable in efficiency. Although the power conversion efficiency of graphene is 4.2% lower than that of a general silicon cell, it will be competitive for special use in the future.
- Q: Do electroplating experiments, graphite as an electrode, graphite how to pre process to ensure that the coating will not fall, resulting in increased color of the solution
- Use a tight filter cloth as an anode pack
- Q: Graphite electrode press device
- Ultra high power graphite electrodes. Use of graphite electrodes with a current density greater than 25A / cm 2. Used primarily in ultra high power arc furnaces
- Q: Excuse me, why does the graphite electrode flake when electrolyzed salt water is used?
- The structure of the electrolytic cell is different when the electrolytic cell is constructed with different electrolytes
- Q: Graphite is made of high-strength graphite, it is a kind of graphite grade specification.
- The difference is: the graphite bar may be machined graphite electrode materials may be insulated with material of graphite. Graphite electrode is an electrode product to guide the processing of graphite material with good electrical properties. Bars are usually cylindrical.
