- 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: Use of graphite in steelmaking
- Graphite can be used as an agent for carburizing in the steel making industry. Carburizing uses a wide range of carbonaceous materials, including synthetic graphite, petroleum coke, metallurgical coke, and natural graphite. Worldwide, the use of graphite for carburizing is still one of the main uses of earth like graphite.
- Q: Electrolytic salt water why use iron as a cathode, all with graphite can not?
- When electrolyzed salt water is used, the cations in the solution (H+, ionized by H2O) are moved to the cathode by the electric field force, and electrons are generated at the cathode to produce H2 hydrogen, and the hydrogen H2 generated does not react with iron
- Q: Why should graphite paper be placed between the heater and the graphite electrode?
- Heater design, the common heater has three shapes, cylinder, cup, spiral, the vast majority of the current heater is cylindrical, as shown in figure. The spiral heater has complicated processing technology and has been eliminated. Cup shaped heater for hemispherical crucible, the bottom melt temperature is more uniform, because the processing technology is difficult, already no use. Nowadays, most of them use cylinder heaters. The cylindrical heater is not only easy to process, but also is related to the large number of flat crucible used in the direct drawing single crystal furnace.
- 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: How can hydrogen be produced by electrolysis of sodium hydroxide with graphite as an electrode?
- You can think so, since sodium has been reduced, so there is always an atom is oxidized, it can only be oxygen oxidation reaction
- Q: Jiqiu conductive graphite electrode, how to compare with copper is relatively large resistance value?
- Look at what kind of graphite electrode you need. Now, the resistivity of ordinary power graphite electrode in our factory is 7.5-8.5. It is not clear that the graphite electrode is dipped in 6--7.3. copper
- Q: What do carbon products include?
- High power electrode and ultra high power electrode. The carbon block can be divided into blast furnace carbon block, aluminum carbon block and electric furnace block. Carbon products can be divided into carbon products, graphite products, carbon fibers and graphite fibers according to the depth of processing. Carbon products can be divided into graphite products, carbon products, carbon fibers and special graphite products according to the raw materials and the production process. Carbon products according to their ash content, and can be divided into multi gray products and less ash products (including ash below l%).
- Q: Electrolysis of CuCl2 solutions with graphite electrodes
- The energization is the electrolysis of CuCl2 solutions, i.e., redox reactions. So you can't mix ionization and electrolysis.
- Q: Graphitized anode, cathode and graphite electrode, respectively How can one differentiate and use differently?
- 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.
