- Q:Graphite can be used in acid towers in chemical plants because of graphite
- The popularization and use of this technology can bring about such economic and social effects: (1) the consumption of graphite electrode units is less, and the production cost is reduced. For example, a steel plant, according to the annual production level did not occur in LF refining furnace 35 week graphite electrode, refining furnace 165 consumption calculation, using anti oxidation technology of graphite electrode, graphite electrode can save 373 per year(153 tons) electrode, each year ultra high power electrode 16900 yuan computation, can save 2 million 585 thousand and 700 yuan rmb.
- Q:Why should the carbon brush for the trolley be made of graphite?
- What you said is the graphite electrode graphite, there may be a high pure graphite graphite conductive rate so high, strong, high density, the graphite is mostly used in motor vehicles, such as generators, and electric tools.
- Q:What kind of asphalt is better for natural graphite coating?
- The graphite electrode includes: (1) ordinary power graphite electrode. Allows the use of current density below 17A / cm 2 graphite electrode, mainly used for steelmaking, smelting silicon, refining yellow phosphorus, such as ordinary power furnace. (2) oxidation resistance coating graphite electrode. A graphite electrode coated with an antioxidant protective layer is applied to form a protective layer that is conductive and resistant to oxidation at high temperature, thereby reducing electrode consumption during steelmaking. (3) high power graphite electrode. A graphite electrode with a current density of 18 ~ 25A / cm 2 is allowed to be used as a high power arc furnace for steelmaking. (4) ultra high power graphite electrode. Permits use of graphite electrodes with current densities greater than 25A / cm 2. Mainly used in ultra high power steelmaking arc furnace.
- 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:Why is graphite a negative pole and copper is an anode?
- Graphite, as an electrode material, can conduct electricity, which belongs to an inert electrode. It only acts as a conductive agent, but does not participate in the electrolytic reaction process. So the anode is made, and copper is oxidized in the electrolysis of monovalent cations, so copper is used as the anode.
- Q:I used 12V direct current, graphite electrode electrolysis sodium sulfide solution, the anode produced a large number of black material, this is why ah?
- Is this principle. Graphite is a layer, each layer, each carbon is SP2 hybrid, and around three carbon connected, finally, between layer and layer formed delocalized covalent bond, making layer and layer can be connected. However, the delocalized covalent bond is not very stable, in attracting Yang Jizheng charge, delocalized covalent bond will certain destruction, the force between the graphite layer and the layer becomes small or not, so as to open.The black stuff is graphite
- Q:How to solve the problem of graphite electrode being crushed during electrolysis
- This graphite electrode is so true because it causes gas to expand and disintegrateTantalum electrodes can be solved and not expensive
- 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:What does graphite electrode GSK mean?
- Graphite board material is GSK, GSK refers to model specifications
- 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
