Q:Graphitized anode, cathode and graphite electrode, respectively How can one differentiate and use differently?
In electrolysis industry, using graphite anode plate as the anode has a history of more than 100 years, the metal anode is in recent decades, the research and application of metal anode in China late last century, only in 70s the technology related to the research and experiment of metal anode, anode on electrolysis industry, mainly through the silver (2%) (0.5%): low silver lead silver alloy, lead and silver tin antimony alloy, lead calcium alloy and lead silver alloy adding nucleating agents and several stages
Q:Excuse me, why does the graphite electrode flake when electrolyzed salt water is used?
Device for electrolytic reaction. The electrolysis bath comprises a tank, an anode and a cathode, the majority of diaphragm separates the anode chamber and a cathode chamber. According to the different electrolyte aqueous solution electrolysis, molten salt electrolytic cell and nonaqueous solution electrolysis. When three kinds of direct current through the electrolytic cell, the anode oxidation the reaction solution and at the interface in the cathode and the electrolyte interface reaction, to produce the required products. To optimize the design of electrolytic cell structure, reasonable selection of electrode and diaphragm material is the key to improve the current efficiency, decrease cell voltage and energy saving.
Q:Thermal expansion coefficient of graphite
Thermal expansion coefficient (100 degrees Celsius --600 degrees Celsius) diameter 200--500 graphite electrode body is not greater than 2.410 of the negative four times per degree Celsius
Q:Graphite powder produced by graphite electrode and what we usually call graphite is a kind of thing?
Coal tar pitch as binder is made by calcination, batching, kneading, pressing, roasting, graphitization and machining
Q:Specification for graphite electrodes commonly used in steel works
General specification for graphite electrode diameter Phi 300 Phi 500mm, Phi Phi 550 - the current usage of 800mm graphite electrodes is also great, the graphite electrode length was between 1600 and 2700mm.
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 high purity graphite component is put into the furnace, and nitrogen and methane are produced under vacuum high temperature. Then graphite is shown to produce 10% coating.
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:Can graphite be used as an electrode for electrolysis of silver in silver nitrate?
Xiaoyi Liyang said the principle is correct, but can get silver? I think we can solve the problem if we take proper measures to get the silver elements, such as separating the anode and the cathode from the salt water!
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.
Q:After vacuum melting of quartz crucible, there are three graphite electrode rods. What's the adjustment?
Or did you adjust the electrode when it was installed? There are two electrode distance, two away, causing melting after different lengths.
