Q:Graphitized coke, graphite, broken, mixed up, how to export?
Graphite fossil oil coke is the best smelting carburizing agent. In the steel-making industry, to produce good steel, there must be good raw materials, including good carburizing agent, and the graphitization of petroleum coke is the best carburizing agent.
Q:Carbon graphite electrode and what is the difference?
The difference between graphite electrode and carbon is mainly composed of graphite manufacturing, the latter for carbon materials,
Q:Synthesis techniques of carbon nanotubes
Catalytic pyrolysis is one of the widely used methods for preparing carbon nanotubes. The method mainly uses transition metal as catalyst, and is suitable for large-scale preparation of carbon nanotubes. The content of carbon nanotubes in the products is higher, but the defects of carbon nanotubes are more.
Q:Thermal expansion coefficient of graphite
The graphite electrode in the thermal expansion coefficient is related with the diameter of the graphite electrode, you have what is the expansion coefficient of specific diameter range not to say it, I put the general heat on high power graphite electrode national Ministry of metallurgical industry YBT/4089--2000 give you a lower coefficient of expansion. For reference only
Q:Graphite electrode in milling machine processing, dust is especially big, boot 5 minutes, workshop can not open the figure, what is the solution?
This is to use the dust collector, the graphite itself is a semiconductor, can not be electrostatic dust removal
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?
Copper ions move toward the cathode, which is the graphite rod connected to the negative electrode of the DC power supply. The color of the solution becomes shallower
Q:The use of graphite as an electrode in alumina electrolysis
Graphite acts as an electrode:The electrical conductivity of graphite, the electrode itself must be electrically conductive;When graphite acts as an anode, it acts as a reducing agent and displaces an element of aluminum in a chemical reaction;Graphite is cheap and cost saving.
Q:Is the anode of electrolytic water suitable for ordinary titanium wires?
Graphite firstFirst of all, the titanium electrode is usually not pure titanium, it should be titanium with a metal oxide coating. Secondly, the advantages of the titanium electrode is mainly to save electricity, the corrosion resistance of carbon is much stronger than that of industrial production, if the meaning is relatively large, but it is still in laboratory experiments, electrolysis of water, not what meaning.
Q:The difference between graphite electrode and graphite rod
The two materials are different.Graphite electrode is mainly in the petroleum coke and needle coke, coal tar pitch as binder, calcination, mixing, kneading, pressing, baking and graphitization, and made the processing machine, is a conductor in an electric arc furnace to form arc release electricity for heating and melting of the charge, according to the quality index level, can is divided into ordinary power, high power and ultra high power.
Q:The reason why graphite is used as electrode
Graphite has good thermal stabilityThe softening point of copper in 1000 degrees, easily deformed by heat, the melting point of graphite is 3850 + 50 DEG C, the boiling point of 4250 DEG C, even after the ultra high temperature arc ignition, the weight loss is very small, the thermal expansion coefficient is small. The strength of graphite increases with the increase of temperature, and the strength of graphite is doubled at 2000 degrees centigrade. In comparison, the thermal expansion coefficient of graphite material is only 1/30 of copper material.
