Q:Synthesis techniques of carbon nanotubes

The synthesis techniques of carbon nanotubes are mainly arc method, laser ablation (Zheng Fa) method, catalytic cracking or catalytic chemical vapor deposition (CCVD), and directional control growth method based on various synthesis techniques.

Q:After electrolysis of CuCl2 solution with graphite electrode for a period of time, we can observe that the graphite surface attached to the DC power supply is attached to the red material,And will the color of the solution be deep or shallow?

Negative poleThe color becomes lighter (the copper ion gets electrons in the cathode and becomes copper)

Q:What about graphite electrodes for steel mills?

Hebei North graphite electrode factory produces various specifications of graphite electrode, with low resistance, high density, small ash, and so on, so that less tons of steel-making, quality is good

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.

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:Graphite powder produced by graphite electrode and what we usually call graphite is a kind of thing?

In the electric arc furnace, the electric energy is released in the form of an arc, and the conductor is heated and melted. According to the quality index, the conductor can be divided into ordinary power, high power and ultra high power.

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:The use of graphite as an electrode in alumina electrolysis

The technical knowledge of electrolytic aluminum, cleaning and maintenance of alumina equipment, you can search for Baidu on the green, looking for.

Q:What is the composition of petroleum coke and what is its use?

Petroleum coke can be used for the manufacture of graphite, smelting and chemical industries, depending on its quality. For example, the quality of cooked sweet coke coke, mainly used in the manufacture of ultra high power graphite electrode and some special carbon products; needle coke in steelmaking industry is an important material new technology development of EAF steelmaking.

Q:The production of one ton of steel required graphite electrode

The consumption of graphite electrode in steelmaking in arc furnace, according to the different material, different specifications of graphite electrode used (normal power graphite electrode, high power graphite electrode, ultra high power graphite electrode) have relations.
