Q:What is the difference between SGL graphite electrode and graphite electrode in general?
Can not say that the more detailed the better, is relative, must be uniform within the range (after all, it is very important to choose the aggregate), such as spectral pure graphite, is not due, he is a lot of technology to producing stains, then burning, and then producing stains, the strength is quite good,
Q:MITSUBISHI machine graphite electrode processing, how does not accumulate carbon?
Carbon deposition can cause insufficient combustion of gasoline and cause engine chattering.
Q:Why is the production of one ton of ultra high power graphite electrode requires 1.05 tons of coke?
After calcined to eliminate ash and volatile part of the points in this process will be a lot of weight loss, in the process of crushing mixing in process of baking or graphite in high temperature heat treatment, another part of the impurities were excluded, so the raw material is higher than the rate of finished products.
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: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:How can hydrogen be produced by electrolysis of sodium hydroxide with graphite as an electrode?
Molten sodium hydroxide is ionized out of Na+ and OH-, electrons are lost at the anode OH-, oxygen and water are produced (immediately evaporated at high temperature), and electrons are generated at Na+ at the cathode Na
Q:I remember the more lively metal, the electron?
C metal is copper, because a dilute sulfuric acid into the H2 precipitation, then definitely not copper. And the inactive first precipitate
Q:Graphite can be used in acid towers in chemical plants because of graphite
A graphite electrode coated with an antioxidant protective layer (graphite electrode, antioxidant). The utility model has the advantages of forming a protective layer capable of conducting electricity and resisting oxidation at high temperature, reducing electrode consumption (19%~50%) during steelmaking, prolonging the service life of electrodes (22%~60%), and reducing the electric energy consumption of electrodes.
Q:What are the losses in graphite electrode?
So tell, this problem is to answer a lot, graphite under high temperature oxidation, generally around 400 degrees, began a slight oxidation, but the human eye is to be observed, with the increase of temperature, the graphite oxide will increase, this time should be used to protect gas or vacuum to protect what you said is, nitrogen protection, and general protection of nitrogen can reach more than 2000 degrees, if the high temperature to 3800 degrees, will you say that vapor formed in graphite surface. To achieve this temperature, it is necessary to add inert gas to achieve, otherwise, can not reach, generally to 4350 degrees, the graphite began to soften.
Q:Graphite powder produced by graphite electrode and what we usually call graphite is a kind of thing?
Graphite electrode is mainly in petroleum coke, coke as raw material
Graphite electrodes are widely used in electric arc furnace and ladle refining furnace for steel making; and used in electric smelting furnace for producing ferroalloys, yellow phosphorus, corundum . The products are well sold to more than 30 countries and regions including Europe, America, Japan, Brazil, South Africa, Australia, the Middle East and so on , and enjoy good reputation. We sincerely welcome domestic and overseas customers to our company for cooperation.
