Q:Please senior doubts. The graphite electrode is used in the mold cavity In what case is graphite processing taken?

Because of the great loss of graphite electrode in finishing, it is not suitable to be used as finishing electrode material. Because of the small coefficient of thermal expansion of graphite, it can also be used as a big electrode material in perforation processing.

Q:Why is the production of one ton of ultra high power graphite electrode requires 1.05 tons of coke?

Petroleum coke is divided into needle coke and sponge coke and projectile reef, fixed carbon content components of petroleum coke is around 80%

Q:Is graphite flammable?Why do I bake pencil cores with a fever that doesn't burn?

In theory, as long as a certain temperature is reached, any substance can be burned, and the diamond is converted to graphite at 2000~3000 DEG C under anaerobic conditions. That is to say, graphite (flake graphite)

Q:Why is graphite a negative pole and copper is an anode?

The process of causing a chemical change by passing through a substance. Chemical change is the process in which material is lost or obtained by electrolysis (oxidation or reduction). Electrolysis is performed in an electrolytic cell. The electrolytic cell is composed of two electrodes, yin and Yang, which are respectively immersed in the solution containing positive and negative ions. The current into the negative electrode (cathode), are positively charged ions migrate to the cathode solution, and with the combination of electronic elements, become neutral or negatively charged molecules; negative ion transfer to another electrode (anode), electrons are given into neutral elements or molecules.

Q:Jiqiu conductive graphite electrode, how to compare with copper is relatively large resistance value?

This is not a good estimate of the sheet graphite resistance after 5mm

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

Mainly used for making carbon products, such as graphite electrodes, anode arc, steel, non-ferrous metals, with aluminum for use; silicon carbide products, such as grinding wheel, rubber, sandpaper; producing goods for the production of synthetic fiber, calcium carbide acetylene and other products; also can be used as fuel for fuel, but for grading impact for grinding superfine grinding, through the JZC-1250 device can be made of coke powder after combustion, using coke powder as fuel is mainly some glass factory, coal water slurry plant etc..

Q:How can hydrogen be produced by electrolysis of sodium hydroxide with graphite as an electrode?

Because there is no hydrogen ions in the molten state of sodium hydroxide, sodium hydroxide and the onlyThis reaction should have occurred,Na+ + e=Na4OH-- 4e=O2+H2O

Q:Can high-purity graphite be used as an electrode?

The thin and deep bone electrode can not be deformed, and the pure graphite electrode is brittle. It is better to break or deform, and can bear high temperature without deformation.

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,
