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?

The copper electrode used for finishing size of the copper electrode discharge speed is not fast but spent graphite electrode is relatively smallRequirements of the high surface, the appearance of products are copper electrode discharge processingThe iron electrode is not clear enough to be used

Q:How do graphitized electrodes differentiate between high power and low power?

Compared with other materials of graphite anode plate has high temperature resistance, good electrical and thermal conductivity, easy machining, good chemical stability, acid and alkali resistance, low ash content; for electrolytic solution, preparation of chlorine, caustic soda, salt alkali electrolytic solution preparation; application such as graphite anode plate can be used as conductive anode electrolytic salt solution preparation of caustic soda. Graphite anode plate can be used as conductive anode in electroplating industry. It is an ideal material for electroplating. It can make electroplating products have the advantages of smoothness, delicacy, wear resistance, corrosion resistance, high brightness and not easy to change color.

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:The difference between graphite electrode and graphite rod

The difference between an electrode and a rod is that the electrode has a lead conductor, and the rod is not.

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

Effect of peak pulse current on electrode wear. The peak current has a great influence on electrode wear, but the curves are very different due to the different materials of the electrode and the workpiece. In the copper electrode machining steel, general peak current, electrode loss is also large, but also have a great relationship with the pulse width, so in practice, we should choose different peak current of different area according to the data processing technology of power supply and discharge pulse width, can make the processing speed is high, and the electrode loss small.

Q:How can the graphite powder be processed into high quality carburizing agent? Thank you

If you are through the material can also be screened and then sold, usually 1-5 of the particle size, fine powder can only add adhesive column

Q:Why use platinum ferroalloy instead of iron as electrode?

General industrial grade silicon dioxide, because the preparation technology is different, can be divided into two types, one is dry, sintered (Fume Type), a wet precipitation type (Precipitated Type), and two of the surface area, the surface with hydroxyl (-OH) are the same, in general, the former the latter is more, less, the two surface has the tendency of hydrophilic, as for lipophilic polymer, such as paint, rubber... Etc.,... If the silica surface pre rendered hydrophobic, has a good effect.

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

Molten sodium hydroxide is ionized out of Na+ and OH-, electrons are lost at the anode OH-, oxygen and water are produced (immediately evaporated at high temperature), and electrons are generated at Na+ at the cathode Na

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

With the development of science and technology, the machine manufacturing technology has undergone profound changes. Due to the social demand for diversification of products is more intense, more varieties, small batch production increasing proportion in WEDM by traditional processing equipment has been difficult to adapt to the processing of high efficiency, high quality, diversified requirements, CNC technology should be used
