FAQ
Why do the normal eletrodes existe broken situation?
There are several reasons, but two are more important:
a. The power is too high, and the electrode can't suport it;
b. The connection between two parts is not good.
- Q:Why is the production of one ton of ultra high power graphite electrode requires 1.05 tons of coke?
- Ultra high power electrode of the main raw material is coke, but in order to increase the strength of the product will add some metallurgical coke, another is in the process of producing stains in coal tar pitch in after graphitization has become one of the A
- Q:What is the role of the Pt electrode? What is the difference between the graphite electrode and the graphite electrode?
- In the electrochemical process, the electrode should not affect the reaction on the working electrode, so platinum and graphite are often chosen
- Q:The original battery is not necessary to form the electrode potential? Why can we use graphite as electrode only? No potential difference.
- Indeed, the original battery electrode potential using two different electrodes, produce potential difference, so that the electron flow generated current. Graphite is used as an electrode because of its excellent electrical conductivity and stability
- Q:Thermal expansion coefficient of graphite
- Thermal expansion coefficient (100 degrees Celsius --600 degrees Celsius) diameter 200--500 graphite electrode body is not greater than 2.410 of the negative four times per degree Celsius
- Q:Electrolytic salt water why use iron as a cathode, all with graphite can not?
- When electrolyzed salt water is used, the cations in the solution (H+, ionized by H2O) are moved to the cathode by the electric field force, and electrons are generated at the cathode to produce H2 hydrogen, and the hydrogen H2 generated does not react with iron
- Q:Why should supercapacitors use graphite as electrode material?
- Because the graphite material's electrochemical stability is good, can let the super capacitor withstand the higher monomer voltage. The electrode is not easy to wear out.
- Q:Graphite electrode specifications, graphite electrode manufacturers which good?
- Graphite electrode to Qingdao Chenyang graphite Co., quality assurance, trustworthy, we have been purchasing graphite electrode for them, you can ask them,
- Q:How about graphite electrode high-temperature oxidation resistant coating?
- Can be used, temperature characteristics of nano composite ceramic coating is more stable, and nano composite ceramic nano high temperature oxidation resistant coatings of different graphite products according to the use conditions, can the temperature of 1600 degrees, forming a dense coating on graphite coated with rust, corrosion, high temperature resistance, oxidation resistance, wear resistance and other properties.
- Q:What's the use of carbon?
- High power graphite electrode. Allows the use of current density of 18 ~ 25A/ cm 2 graphite electrode, mainly used in steel-making high power arc furnace
- Q:National standard for graphite electrodes
- The national standard normal power graphite electrode graphite electrode: the standard name standard classification number Q51 Standard No. YB/T 4088-2000 for YB/T 4088-2000 YB/T 4088-1992 2000/12/1, instead of the execution time of 0:00:00 release time 2000/7/26 0:00:00 adoption situation
