Q:Electrolytic water solution, two electrodes are graphite electrode, the negative electrode can produce large amounts of hydrogen, the anode does not produce half of oxygen, and only a small amount of it?

Graphite electrodes react with oxygen to form carbon dioxide, soluble in water

Q:The reason why graphite is used as electrode

Good chemical stabilityGraphite has good chemical stability at room temperature. It can resist acid, alkali and organic solvent.

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

Ultra high power electrode of the main raw material is coke, but in order to increase the strength of the product will add some metallurgical coke, another is in the process of producing stains in coal tar pitch in after graphitization has become one of the A

Q:What are the factors that affect the electrode wear rate of machine tools?

In the pulse peak voltage, current and pulse width decreased, the electrode loss increase, and the heat produced from the processing of large pulse width, is conducive to the adsorption of copper electrode graphitization induced by carbon, which is commonly referred to as the covering effect".

Q:What is the striking electrode in the die making? Where is the technical point?

Electrical discharge machining (EDM) is a spark discharge in a liquid medium at a lower voltage range to meet the required shape and size.

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 utility model has the advantages of small density and suitable tool electrodes for processing large parts or moulds, and the whole quality is small.

Q:What is the application of wire cutting with graphite electrode?

Greatly shorten the preparatory time of mechanical processing, and improve the level of automation of the whole process of machining, and also enhance the ability of the manufacturing system to adapt to changes in production conditions.

Q:How does graphite produce solar cells?

The team at the Massachusetts Institute of Technology has confirmed that electrodes based on graphene and ITO devices are comparable in efficiency. Although the power conversion efficiency of graphene is 4.2% lower than that of a general silicon cell, it will be competitive for special use in the future.

Q:The graphite electrode made by the machining center adopts cooling method, which is water cooled, oil cooled and blow cold. Which is good?

Use oil cold. Air cooling will cause graphite dust flying, on the one hand, toxic, on the one hand there are security risks (caused by circuit short circuit). Water cooling is virtually out of use, taking into account the maintenance and maintenance of the CNC.
