We have established the international advanced quality management system，every link from raw material to final product we have strict quality test；We resolutely put an end to unqualified products flowing into the market. At the same time, we will provide necessary follow-up service assurance.
- Q: How to solve the problem of graphite electrode being crushed during electrolysis
- This graphite electrode is so true because it causes gas to expand and disintegrateTantalum electrodes can be solved and not expensive
- 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: Will the concentration of electrolytic sodium sulfite be increased with graphite as electrode?
- Can't。 During electrolysis, there is depletion of sulfite ions.
- Q: Graphite can be used in acid towers in chemical plants because of graphite
- Ultra high power graphite electrode. A graphite electrode that allows current densities greater than 25A/ cm 2 is allowed. Mainly used in ultra high power steelmaking arc furnace
- Q: Are graphite and carbon electrodes the same? What kinds of ore furnaces are used?
- The main components of carbon electrodes are graphite, carbon powder and other impurities which are not converted into graphite. The resistivity is higher than that of graphite electrode. These electrodes are mostly used in electric furnace steelmaking, smelting aluminium oxide and other electric arc furnaces.
- Q: How should carbon deposits be treated?
- It is very necessary to clean the throttle valve, clean the nozzle, and clean the carbon in the engine cylinder! However, in order to reduce the trouble of cleaning, it is best to join the regular application of graphene Moqi additive in lubricating oil for engine.
- Q: 800KVA and 12500 EAF transformer data graphite electrode furnace.
- The graphite electrode must be roasted by a cathode or anode baking furnace, and a large amount of harmful gas and dust will be produced during the roasting process.
- Q: How about graphite electrode high-temperature oxidation resistant coating?
- Heat resistant coating is generally able to withstand 300 degrees below the temperature, commonly used aluminum heat-resistant paint, high temperature resistance can withstand higher temperatures, such as 800 degrees or more, commonly used silicone heat-resistant paint
- Q: Graphitized anode, cathode and graphite electrode, respectively How can one differentiate and use differently?
- In an electrolytic cell, the current from a class called graphite anode plate into the electrolyte electrolysis industry, the anode is made of plate shape, so called graphite anode plate, widely used in electroplating, wastewater treatment, industrial anti-corrosion equipment or special materials.
- Q: What is the difference between SGL graphite electrode and graphite electrode in general?
- In fact, the graphite electrode abroad (including Japan) in several ways than we can control the fine, one is pure, another is anisotropic (resistance, thermal conductivity ah) usually do some control, in the strength of domestic now is also doing well, but when we are comparing high quality products, general domestic products it is basically a piece of the indicators are poor
