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:Will the brush grease not short-circuit the commutator?: Graphite, on the other hand, has good lubrication. The graphite base electrode will form a layer of carbon film when it rotates on the surface of the motor commutator. It can reduce the friction coefficient between the brush and the commutator and reduce the wear of the commutator effectively.

Q:How large is the permissible overload current per square millimeter of the graphite electrode cross section?: Overhead wires, radiating the best conditions, allowed the current largest. The insulated wire in the house is laid in the wall, which has the worst heat release conditions and the smaller permissible current, so there are different safety currents.

Q:What is the composition of petroleum coke and what is its use?: Medium sulphur and common cooked coke; used in large quantities for aluminium smelting. High sulfur, ordinary coke is used in chemical production, such as the manufacture of calcium carbide, silicon carbide, etc., but also as a metal casting and other fuels. Most of the petroleum coke produced in China belongs to low sulfur coke, which is mainly used for smelting aluminium and making graphite.

Q:Why should the carbon brush for the trolley be made of graphite?: Graphite conducts electricity and is self lubricant, resistant to wear. As for why, high school chemistry textbooks have ah.

Q:I used 12V direct current, graphite electrode electrolysis sodium sulfide solution, the anode produced a large number of black material, this is why ah?: Is this principle. Graphite is a layer, each layer, each carbon is SP2 hybrid, and around three carbon connected, finally, between layer and layer formed delocalized covalent bond, making layer and layer can be connected. However, the delocalized covalent bond is not very stable, in attracting Yang Jizheng charge, delocalized covalent bond will certain destruction, the force between the graphite layer and the layer becomes small or not, so as to open.The black stuff is graphite

Q:What's the use of carbon?: Oxidation resistant coating graphite electrode. A graphite electrode coated with an antioxidant protective layer is applied to form a protective layer that is conductive and resistant to oxidation at high temperature, thereby reducing electrode consumption during steelmaking.

Q:How can I electroplate iron? I would like to use graphite as an electrode. Iron is plated on graphite with iron solution, so it can be processed into iron parts. I wonder if it can be done: Iron plating can be, with 2 valence iron, but on the graphite joint force is good, it is difficult to say, electroplating is bad, peeling is also common. Relatively speaking, iron parts on nickel plating is relatively simple, also more applicable

Q:Graphite can be used in acid towers in chemical plants because of graphite: The popularization and use of this technology can bring about such economic and social effects: (1) the consumption of graphite electrode units is less, and the production cost is reduced. For example, a steel plant, according to the annual production level did not occur in LF refining furnace 35 week graphite electrode, refining furnace 165 consumption calculation, using anti oxidation technology of graphite electrode, graphite electrode can save 373 per year(153 tons) electrode, each year ultra high power electrode 16900 yuan computation, can save 2 million 585 thousand and 700 yuan rmb.

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.

Our products have been sold to Europe, Southeast Asia, South America, India, and other countries and regions. Meanwhile, Our Graphite Electrodes and nipples have already been ISO9001:2000 approved. We will pay attention to product quality and offer you the best price. We hope that we could establish business relationships with all friends on the basis of equality and mutual benefits.
