G grade Carbon Electrode 500-700 CNBM China Silicon Production

Q:Why is the production of one ton of ultra high power graphite electrode requires 1.05 tons of coke?: Petroleum coke is divided into needle coke and sponge coke and projectile reef, fixed carbon content components of petroleum coke is around 80%

Q:Are graphite and carbon electrodes the same? What kinds of ore furnaces are used?: Graphite electrode should be relatively pure, composed of graphite.

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:Electrolysis of CuCl2 solutions with graphite electrodes: CuCl2 refers to a copper chloride ionization ionization ion and chloride ion in aqueous solution, the equivalent of CuCl2 does not exist, but there are only Cu2+ and Cl-, even if there is no electricity, the ionization will happen, because this is the nature of it.

Q:Jiqiu conductive graphite electrode, how to compare with copper is relatively large resistance value?: Look at what kind of graphite electrode you need. Now, the resistivity of ordinary power graphite electrode in our factory is 7.5-8.5. It is not clear that the graphite electrode is dipped in 6--7.3. copper

Q:What are pyrolytic graphite electrodes used for?: Discharge consumption; because the spark oil also contains C atoms in the discharge process, high temperature oil spark decomposition of C atom, and form a protective film on the surface of the graphite electrode, graphite electrode loss compensation.

Q:Graphite electrode press device: (1) ordinary power graphite electrode, using graphite electrode with current density lower than 17A / cm 2, is mainly used in steel-making, smelting silicon, refining yellow phosphorus and other common power electric stove(2) anti oxidation coating graphite electrode. The surface is coated with an anti oxidation protective layer of graphite electrode to form a protective layer which has both conductive and high-temperature oxidation resistance, thus reducing the electrode consumption during steelmaking

Q:What's the purpose of the electrode material?When the electrolytic molten state of NaCl is said, what is the use of the graphite electrode and the iron electrode?: 1. graphite (two kinds of EDM3 and EDM200)2. copperIn general, graphite electrode for extensive escape material (graphite texture loose, discharge energy is relatively large, removal of materials faster, but face flowers that roughness is relatively large

Q:Excuse me, why does the graphite electrode flake when electrolyzed salt water is used?: Device for electrolytic reaction. The electrolysis bath comprises a tank, an anode and a cathode, the majority of diaphragm separates the anode chamber and a cathode chamber. According to the different electrolyte aqueous solution electrolysis, molten salt electrolytic cell and nonaqueous solution electrolysis. When three kinds of direct current through the electrolytic cell, the anode oxidation the reaction solution and at the interface in the cathode and the electrolyte interface reaction, to produce the required products. To optimize the design of electrolytic cell structure, reasonable selection of electrode and diaphragm material is the key to improve the current efficiency, decrease cell voltage and energy saving.

Q:Why is graphite a negative pole and copper is an anode?: Electrolysis (Electrolysis) is the current through the electrolyte solution or molten electrolyte (also called electrolyte), caused by the redox reaction in the cathode and the anode, the electrochemical cell can occur when an external DC voltage in the electrolysis process.
