Do you know our material of the graphite electrode?

The regular power graphite electrode is made from petroleum coke with a little pitch, which meets

the state standards YB/T4088-2000

The high power graphite electrode is made form 70% petroleum coke and 30% imported needle

coke, which meets the state standards YB/T4089-2000

The ultra high power graphite electrode is made form 100% imported needle coke, which meets

the state standards YB/T 4090-200

Note: Needle coke is one kinds of very important material to produce the high grade graphite

electrode,which is rapid development in carbon graphite industry. The needle coke own the

following characteristics: low electric resistance, low dilatation coefficient, good electric and

thermal conductivity,high oxidation resistance, greater resistance to thermal and mechanical

shock, high mechanical strength, high machining accuracy, low consume.

Graphite Electrode/High Purity CNBM Graphite

Q:What's the purpose of the electrode material?When the electrolytic molten state of NaCl is said, what is the use of the graphite electrode and the iron electrode?: 1. graphite (two kinds of EDM3 and EDM200)2. copperIn general, graphite electrode for extensive escape material (graphite texture loose, discharge energy is relatively large, removal of materials faster, but face flowers that roughness is relatively large

Q:MITSUBISHI machine graphite electrode processing, how does not accumulate carbon?: The three is difficult cold start, is sparking difficult, not easy car, and finally the combustion chamber carbon Yan will cause a heavy cylinder knock, low speed and acceleration noise, causing damage to the piston and crankshaft, causing the engine temperature which can seriously affect the automobile safety. Emission standards exceeded, not only through the annual inspection, but also directly aggravate the pollution of the environment

Q:Can graphite be used as an electrode for electrolysis of silver in silver nitrate?: If it is molten, it can be made out of silverFor solution, only AgNO3+H2O== electrolysis ==Ag+HNO3+O2 is analyzedWhen the HNO3 concentration is enough, it will continue to react with Ag.... So you can't get Ag elements.

Q:What is the difference between pyridine type nitrogen and graphite type nitrogen?: In fact, this problem is very simple, the carbon graphite is six square lattice ordered, natural graphite and artificial graphite is divided into two kinds: the classification of natural graphite flake graphite and graphite is earthy, basically it is not forming soil shaped graphite graphite, are rough machining, the battery core and do more. The use ratio of flake graphite.

Q:What is the role of the Pt electrode? What is the difference between the graphite electrode and the graphite electrode?: In the electrochemical process, the electrode should not affect the reaction on the working electrode, so platinum and graphite are often chosen

Q:What kind of asphalt is better for natural graphite coating?: The graphite electrode includes: (1) ordinary power graphite electrode. Allows the use of current density below 17A / cm 2 graphite electrode, mainly used for steelmaking, smelting silicon, refining yellow phosphorus, such as ordinary power furnace. (2) oxidation resistance coating graphite electrode. A graphite electrode coated with an antioxidant protective layer is applied to form a protective layer that is conductive and resistant to oxidation at high temperature, thereby reducing electrode consumption during steelmaking. (3) high power graphite electrode. A graphite electrode with a current density of 18 ~ 25A / cm 2 is allowed to be used as a high power arc furnace for steelmaking. (4) ultra high power graphite electrode. Permits use of graphite electrodes with current densities greater than 25A / cm 2. Mainly used in ultra high power steelmaking arc furnace.

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:What are the losses in graphite electrode?: In what environment is the loss, friction, or in the case of high temperature, high temperature will be oxidized, and if in the case of friction, you can first use more wear-resistant graphite material. So please ask this question clearly, and then answer you, thank you.

Q:How does graphite produce solar cells?: Gerrit J said: "despite the modifications, but the inherent nature of graphene remains unchanged, is a significant advantage of composite materials."

Q:How can I electroplate iron? I would like to use graphite as an electrode. Iron is plated on graphite with iron solution, so it can be processed into iron parts. I wonder if it can be done: Iron plating can be, with 2 valence iron, but on the graphite joint force is good, it is difficult to say, electroplating is bad, peeling is also common. Relatively speaking, iron parts on nickel plating is relatively simple, also more applicable
