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

The reason is that the resistance increases continuously, the number of ions is limited, and the conductivity is limited

Q:Classification, uses and manufacturers of graphite electrodes

Classification of graphite electrodes:(1) common power graphite electrode (RP), (2) high power graphite electrode (HP), (3) quasi ultra high power graphite electrode (SHP), (4) ultra high power graphite electrode (UHP) Note: poly carbon classification method

Q:How large is the permissible overload current per square millimeter of the graphite electrode cross section?

9A/mm2 safety current should be bare overhead, 5A/mm2 is obviously insulation lines, the indoor environment standards.

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:Which department in the steel plant needs graphite in large quantities?

The variety and specifications of graphite electrodes used in modern EAF steelmaking are mainly determined by the technical parameters of the steelmaking furnace. With the development of EAF steelmaking technology, the steel-making technology is developing towards large scale and ultra high power. The graphite electrode is mainly made of large size graphite electrode and ultra high power graphite electrode.

Q:The future of graphene

Field of semiconductor materials. Graphene is considered to be an ideal material for replacing silicon. A large number of powerful enterprises have developed graphene semiconductor devices. The Han Guocheng Institute has developed a highly stable n type graphene semiconductor that can be exposed to air for a long time. Graphene silicon optoelectronic hybrid chip developed by Columbia University has broad application prospects in optical interconnection and low power photonic integrated circuit. IBM researchers have developed graphene field effect transistors with cutoff frequencies of up to 100GHz, with frequency performance far superior to the cut-off frequency of the most advanced silicon transistors of the same gate length.

Q:National standard for graphite electrodes

The national standard normal power graphite electrode graphite electrode: the standard name standard classification number Q51 Standard No. YB/T 4088-2000 for YB/T 4088-2000 YB/T 4088-1992 2000/12/1, instead of the execution time of 0:00:00 release time 2000/7/26 0:00:00 adoption situation

Q:The graphite electrode made by the machining center adopts cooling method, which is water cooled, oil cooled and blow cold. Which is good?

I had worked on graphite electrodes for 3 years before, and the fact told me that in addition to using the wind to remove the powder, the others were ineffective or disorderly. Because you have to measure size while processing.

Q:What is the graphite furnace electrode with a diameter of 400?

The variety and specifications of graphite electrodes used in modern EAF steelmaking are mainly determined by the technical parameters of the steelmaking furnace.

Q:Graphitized coke, graphite, broken, mixed up, how to export?

The graphite powder is soft, black and gray, greasy and polluting paper. Hardness is 1~2, along the vertical direction with the increase of impurities, its hardness can be increased to 3~5. The specific gravity is 1.9 ~ 2.3. Under isolated oxygen conditions, the melting point is above 3000 degrees Celsius and is one of the most refractory minerals. At room temperature, the chemical properties of stone toner are relatively stable, insoluble in water, dilute acid, dilute alkali and organic solvents. The material has high temperature resistance and conductivity, and can be used as refractory materials, conductive materials, wear-resistant and lubricating materials.
