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: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:Excuse me, why does the graphite electrode flake when electrolyzed salt water is used?
Aqueous solution electrolytic cell has no diaphragm and diaphragm. Two kinds of commonly used diaphragm electrolyzer. In chlorate production and mercury method to produce chlorine and caustic soda, with no diaphragm electrolyzer. Try to increase the surface area per unit volume, can improve the production strength of electrolytic cell. Therefore, the modern electrode diaphragm electrolyzer the vertical components due to internal electrolysis. The material and structure and installation of different performance and different characteristics.
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.
Q:Synthesis techniques of carbon nanotubes
Catalytic pyrolysis is one of the widely used methods for preparing carbon nanotubes. The method mainly uses transition metal as catalyst, and is suitable for large-scale preparation of carbon nanotubes. The content of carbon nanotubes in the products is higher, but the defects of carbon nanotubes are more.
Q:I remember the more lively metal, the electron?
Metal ion is more inert electron, graphite electrode for electrolytic salt solution containing the same amount of substance A and C two metals, C first precipitated, so C is copper. In a dilute sulfuric acid with H2 precipitation, certainly not a copper. The more active metal betatopic ability is strong, have the corresponding ion electronic ability weaker. First metal ions corresponding to metal electrons are not active.
Q:What are the factors affecting the service life of graphite electrode in ultra high power arc furnace?
The ultra high power graphite electrodes produced in China are 300mm, 350mm, 400mm, 450mm, 550mm, 600mm, 650mm, 500mm and 700mm, with lengths of 1600mm, 1800mm, 2000mm, 2200mm, 2400mm and 2700mm.
Q:What is the graphite furnace electrode with a diameter of 400?
The variety and specifications of graphite electrodes used in modern EAF steelmaking are mainly determined by the technical parameters of the steelmaking furnace.
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:The graphite electrode made by the machining center adopts cooling method, which is water cooled, oil cooled and blow cold. Which is good?
I had worked on graphite electrodes for 3 years before, and the fact told me that in addition to using the wind to remove the powder, the others were ineffective or disorderly. Because you have to measure size while processing.
