Q:Graphite graphite graphite graphite electrode what is the use?

Natural graphite electrode is the main raw material with graphite, high purity flake graphite powder or high carbon flake graphite powder as raw material, because carbon or graphite powder purity is high, the effect of conductive graphite powder is better in smelting alloy steel, iron alloy, electrode graphite powder as raw material. The electrode produced, then the strong current through the melting zone, the arc electrode into the electric furnace, the electrical energy into heat, the temperature rises to 2000 degrees Celsius, so as to achieve the purpose of melting or reaction.

Q:Why should the carbon brush for the trolley be made of graphite?

Graphite conducts electricity and is self lubricant, resistant to wear. As for why, high school chemistry textbooks have ah.

Q:I remember the more lively metal, the electron?

C metal is copper, because a dilute sulfuric acid into the H2 precipitation, then definitely not copper. And the inactive first precipitate

Q:Where is the graphite electrode scrap?

Finally, a bright white Ar-ICP discharge is formed, especially like a drop of water droplets.

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:Why is graphite conductive electrode oxidized?

Graphite electrode uses petroleum coke (carbon), pitch coke (carbon) as granule material

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

You can think so, since sodium has been reduced, so there is always an atom is oxidized, it can only be oxygen oxidation reaction

Q:What is the difference between SGL graphite electrode and graphite electrode in general?

Can not say that the more detailed the better, is relative, must be uniform within the range (after all, it is very important to choose the aggregate), such as spectral pure graphite, is not due, he is a lot of technology to producing stains, then burning, and then producing stains, the strength is quite good,

Q:In EDM, the electrodes are made of graphite and copper. Please tell us the difference between them

For operators, copper is certainly better, graphite will have dust, the human body has serious harm

Q:Specification for graphite electrodes commonly used in steel works

In general, the graphite electrode used in steelmaking furnace is mostly made of ordinary power and high power graphite electrode. Now, the use of ultra high power graphite electrode increases year by year, accounting for almost half of the graphite electrode.
