Q:National standard for graphite electrodes
Page 7 the international standard specifies the shape, dimensions and tolerances, technical requirements, test methods, packaging, marking, storage, transportation and quality certificates of graphite electrodes. This standard applies to high quality petroleum coke, asphalt, coke as the main raw material, through molding, roasting, impregnation, graphitization and mechanical processing made of, power supply arc furnace as conductive material of ordinary power graphite electrode. Common power graphite electrode GB
Q:How to solve the problem of graphite electrode being crushed during electrolysis
There's no way. It's an industrial problem, and that's how graphite works.
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:Does the silicon carbide heat plant require a fine structure graphite electrode? What kind of graphite products do you need?
But because the silicon carbide is too hard, it is difficult to machining, good workability, such as non special requirements, using graphite instead of silicon carbide, instead of the effect is not good, but can use a silicon carbide, easy processing, small life than silicon carbide.
Q:What are the structures of pyrolytic graphite electrodes? What are their properties and applications? We hope that some details will not be found
The graphite part is called pyrolytic graphite. Stronger than ordinary graphite, strong oxidation resistance.
Q:What are the factors affecting the service life of graphite electrode in ultra high power arc furnace?
The ultra high power graphite electrodes produced in China are 300mm, 350mm, 400mm, 450mm, 550mm, 600mm, 650mm, 500mm and 700mm, with lengths of 1600mm, 1800mm, 2000mm, 2200mm, 2400mm and 2700mm.
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: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:How do graphitized electrodes differentiate between high power and low power?
In electrolysis industry, using graphite anode plate as the anode has a history of more than 100 years, the metal anode is in recent decades, the research and application of metal anode in China late last century, only in 70s the technology related to the research and experiment of metal anode, anode on electrolysis industry, mainly through the silver (2%) (0.5%): low silver lead silver alloy, lead and silver tin antimony alloy, lead calcium alloy and lead silver alloy adding nucleating agents and several stages.
Q:Electrolytic water solution, two electrodes are graphite electrode, the negative electrode can produce large amounts of hydrogen, the anode does not produce half of oxygen, and only a small amount of it?
Graphite electrodes react with oxygen to form carbon dioxide, soluble in water
