Q:Why is graphite conductive electrode oxidized?
Coal tar pitch is a kind of high temperature resistant graphite conductive material, which is made of coal tar pitch as binder. It is made by calcination, crushing, mixing, kneading, forming, roasting, graphitization and mechanical processing. It is called graphite electrode
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:Use of graphite in steelmaking
Graphite can be used as an agent for carburizing in the steel making industry. Carburizing uses a wide range of carbonaceous materials, including synthetic graphite, petroleum coke, metallurgical coke, and natural graphite. Worldwide, the use of graphite for carburizing is still one of the main uses of earth like graphite.
Q:What are pyrolytic graphite electrodes used for?
In 1960s, copper is widely used as electrode material, usage rate of about 90%, about graphite only 10%; in twenty-first Century, more and more users start using graphite as the electrode material, in Europe, more than 90% above the graphite electrode material is. Copper, the once dominant electrode material, has almost lost its advantages over graphite electrodes.
Q:What is the reason that the current cannot be increased when the graphite electrode is used for anode electrolysis?Add calcium chloride and sodium bicarbonate into electrolytic water
Because in the process of electrolysis of water in cathode electron generated hydroxyl, the alkaline solution increased. But with the hydroxyl reaction of sodium carbonate and sodium bicarbonate, carbonate and calcium ions exist at the same time, must produce the precipitation of calcium carbonate, the ion in the solution is reduced, thereby conductive resistance increases. Thus weakened over time current cannot be raised
Q:Can Naiduo high temperature graphite
Graphite cut gasket is from pure graphite plate drilling or cutting and it has good corrosion resistance, high / low temperature, compression elasticity and high strength good, complex geometric gasket circular is widely used in all kinds of pipes, valves, pumps, pressure vessels, heat exchanger, and condenser generator, air compressor, exhaust pipe, refrigerator etc..
Q:Can high-purity graphite be used as an electrode?
The high purity graphite electrode has little wear and is suitable for increasing the machining of the cavity;
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: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:What are the losses in graphite electrode?
In what environment is the loss, friction, or in the case of high temperature, high temperature will be oxidized, and if in the case of friction, you can first use more wear-resistant graphite material. So please ask this question clearly, and then answer you, thank you.
