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:Why should graphite paper be placed between the heater and the graphite electrode?

Heater design, the common heater has three shapes, cylinder, cup, spiral, the vast majority of the current heater is cylindrical, as shown in figure. The spiral heater has complicated processing technology and has been eliminated. Cup shaped heater for hemispherical crucible, the bottom melt temperature is more uniform, because the processing technology is difficult, already no use. Nowadays, most of them use cylinder heaters. The cylindrical heater is not only easy to process, but also is related to the large number of flat crucible used in the direct drawing single crystal furnace.

Q:What are the structures of pyrolytic graphite electrodes? What are their properties and applications? We hope that some details will not be found

The graphite part is called pyrolytic graphite. Stronger than ordinary graphite, strong oxidation resistance.

Q:After electrolysis of CuCl2 solution with graphite electrode for a period of time, we can observe that the graphite surface attached to the DC power supply is attached to the red material,And will the color of the solution be deep or shallow?

Copper ions move toward the cathode, which is the graphite rod connected to the negative electrode of the DC power supply. The color of the solution becomes shallower

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

Instead of copper as discharge material.1. Electrode design1 can reduce the number of individual electrodes / can be made into a composite electrode2, it can save the electrode clamp system and save the cost2, the electrode processing1, high speed milling rough processing copper block 3 times2, high-speed milling finishing faster than copper 5 times3. Good machinability4, complex geometric modeling can be realized3, light weight, its density is less than 1/4 of copper1, good thermal stability (without deformation)2 can reduce the number of individual electrodes / can be made into a composite electrode3, without deburring4. The electrode is easy to clamp4 、 electric discharge machining EDM1, roughing, the electrode loss is small2, high work removal rate3 can reduce the number of individual electrodes / can be made into a composite electrode4. No pollution to the environment in the electrolyte5, light weight, its density is less than 1/4 of copper6, excellent thermal stability, the electrode does not change7, the fine graphite electrode can be used to produce high quality workpiece surfaceDifferent grades of graphite materials can be used for processing different workpieces

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:Why use platinum ferroalloy instead of iron as electrode?

Silica (Silica) is widely used in paint, ink, plastic, rubber and cosmetics, are often added to increase the performance of silica, such as oil absorption, extinction, strengthen the mechanical... Etc., and can reduce the cost of...

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:Graphite electrode specifications, graphite electrode manufacturers which good?

The key is you use and what type of need, say, abroad, what Dongyang, sigley are good, but also, very expensive, you can also choose to try our home

Q:Is the anode of electrolytic water suitable for ordinary titanium wires?

Graphite firstFirst of all, the titanium electrode is usually not pure titanium, it should be titanium with a metal oxide coating. Secondly, the advantages of the titanium electrode is mainly to save electricity, the corrosion resistance of carbon is much stronger than that of industrial production, if the meaning is relatively large, but it is still in laboratory experiments, electrolysis of water, not what meaning.
