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:Can Naiduo high temperature graphite
Graphite gasket medium: hot water, steam, oil, acid, alkali, ammonia, hydrogen, organic solvents, hydrocarbons, cryogenic liquids, etc..Maximum use pressure of graphite gasket: 30MPa.Service temperature of graphite gasket: -200~650
Q:How to solve the problem of graphite electrode being crushed during electrolysis
I can only use the experience of the past to tell you that if you want to save money easily, the time can be considered as the costA thick graphite stick; inexpensive
Q:The production of one ton of steel required graphite electrode
Can not generally say, a ton of steel production consumes much of graphite electrode.
Q:The use of graphite as an electrode in alumina electrolysis
Graphite acts as an electrode:The electrical conductivity of graphite, the electrode itself must be electrically conductive;When graphite acts as an anode, it acts as a reducing agent and displaces an element of aluminum in a chemical reaction;Graphite is cheap and cost saving.
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: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:Will the concentration of electrolytic sodium sulfite be increased with graphite as electrode?
Not alwaysIt depends on the rate of electrolyzed water or the rate at which sodium sulfite is oxidized.
Q:How can I electroplate iron? I would like to use graphite as an electrode. Iron is plated on graphite with iron solution, so it can be processed into iron parts. I wonder if it can be done
Iron plating can be, with 2 valence iron, but on the graphite joint force is good, it is difficult to say, electroplating is bad, peeling is also common. Relatively speaking, iron parts on nickel plating is relatively simple, also more applicable
Q:800KVA and 12500 EAF transformer data graphite electrode furnace.
The graphite electrode must be roasted by a cathode or anode baking furnace, and a large amount of harmful gas and dust will be produced during the roasting process.
