Q:What is the reason that the current cannot be increased when the graphite electrode is used for anode electrolysis?Add calcium chloride and sodium bicarbonate into electrolytic water: The first answer to the equation above is quite right, or it may be that a layer of calcium carbonate is attached to the surface of the electrode, which prevents the electrode from conducting and leads to an increase in resistance

Q:The reason why graphite is used as electrode: Graphite is good in plasticity and easier to be machined preciselyGraphite material has the advantages of high processing accuracy and good surface effect, especially in the processing of precise, complex, thin-walled and Gao Ying material mold cavity. Because the cutting resistance of graphite is only 1/5 of copper material, it is easier to do manual grinding and polishing on the operation. There is no burr after graphite processing, and it is easier to realize automatic production. Complex geometric modeling can be realized.

Q:Graphite is made of high-strength graphite, it is a kind of graphite grade specification.: Most of the graphite electrodes are cylindrical, but also have square and multi ribbed shapes. Graphite blank refers to the firing of raw materials without processing graphite.

Q:Graphite electrode in milling machine processing, dust is especially big, boot 5 minutes, workshop can not open the figure, what is the solution?: Because will cause a short circuit, the best selection of bag type dust collector, our company is graphite in Linzhou, and before you like, then Xinxiang Keli machinery to help us to design a set of dust removal equipment, and then the operation almost no dust, you can consult the specific

Q:What is the difference between pyridine type nitrogen and graphite type nitrogen?: High purity graphite is said to produce graphite electrode, ash is very low, generally below 10 million.

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:Electrolytic salt water why use iron as a cathode, all with graphite can not?: The iron electrode is easier to be installed in the electrolytic cell, which is more convenient than the graphite electrode, and the density of the graphite is small. After being adsorbed by hydrogen, the graphite is easy to float up, and the density of the iron is larger. This problem does not exist in the.5

Q:How can the graphite powder be processed into high quality carburizing agent? Thank you: So that impurities on the high, so basically can not be processed into so-called quality, and can leave a contact, discuss each other

Q:Synthesis techniques of carbon nanotubes: Laser evaporation is an effective method for the preparation of single-walled carbon nanotubes. Single walled carbon nanotubes and single-walled carbon nanotube bundles were prepared by evaporation of carbon targets doped with Fe, Co, Ni or their alloy by high energy CO2 laser or Nd/YAG laser. The diameter of the tubes can be controlled by laser pulses. The researchers found that the shorter the laser pulse interval, the higher the yield of SWNTs, while the SWNT structure was not affected by the pulse interval time. Using CO2 laser evaporation method for single wall carbon nanotubes at room temperature, if the use of fast imaging technology and emission spectra can be observed in morphology of smoke and carbon containing debris flow evaporation in argon, the diagnostic technology makes the growth process of single wall carbon nanotubes tracking possible. The main disadvantage of laser evaporation (ablation) is that the purity of single walled carbon nanotubes is low and easy to entangle.

Q:Please senior doubts. The graphite electrode is used in the mold cavity In what case is graphite processing taken?: Graphite electrode has better machining stability and high production efficiency. It is easy to be used as EDM electrode material in EDM when it is processed with long pulse width and high current.

Our products have been sold to Europe, Southeast Asia, South America, India, and other countries and regions. Meanwhile, Our Graphite Electrodes and nipples have already been ISO9001:2000 approved. We will pay attention to product quality and offer you the best price. We hope that we could establish business relationships with all friends on the basis of equality and mutual benefits.
