- Q:What is the reason that the current cannot be increased when the graphite electrode is used for anode electrolysis?Add calcium chloride and sodium bicarbonate into electrolytic water
- Because in the process of electrolysis of water in cathode electron generated hydroxyl, the alkaline solution increased. But with the hydroxyl reaction of sodium carbonate and sodium bicarbonate, carbonate and calcium ions exist at the same time, must produce the precipitation of calcium carbonate, the ion in the solution is reduced, thereby conductive resistance increases. Thus weakened over time current cannot be raised
- Q:The reason why graphite is used as electrode
- Graphite has good thermal stabilityThe softening point of copper in 1000 degrees, easily deformed by heat, the melting point of graphite is 3850 + 50 DEG C, the boiling point of 4250 DEG C, even after the ultra high temperature arc ignition, the weight loss is very small, the thermal expansion coefficient is small. The strength of graphite increases with the increase of temperature, and the strength of graphite is doubled at 2000 degrees centigrade. In comparison, the thermal expansion coefficient of graphite material is only 1/30 of copper material.
- Q:What is the application of wire cutting with graphite electrode?
- Machine: wire cutting wire, wire EDM, wire EDM wire is the cutting machine.
- Q:After electrolysis of CuCl2 solution with graphite electrode for a period of time, we can observe that the graphite surface attached to the DC power supply is attached to the red material,And will the color of the solution be deep or shallow?
- During electrolysis, cations move toward the cathode, electrons are reduced at the cathode, anions are moved toward the anode, electrons are lost at the anode and oxidized. And you use both sides of the graphite rod, is inert electrode, so there will be no copper ions added to the solution, copper in the solution of consumption, the color of natural shallow.
- Q:Which department in the steel plant needs graphite in large quantities?
- Steelmaking department. The graphite electrode steelmaking is to enter the electric energy through the graphite electrode to the electric arc furnace, and takes the arc between the electrode end and the furnace charge as the heat source to carry on the steel smelting. The electric arc furnace takes electric energy as heat source, and can adjust the atmosphere in the furnace. It is very beneficial to smelt the steel which contains more easily oxidized elements. Smelting a variety of alloys
- 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:Synthesis techniques of carbon nanotubes
- Catalytic pyrolysis is one of the widely used methods for preparing carbon nanotubes. The method mainly uses transition metal as catalyst, and is suitable for large-scale preparation of carbon nanotubes. The content of carbon nanotubes in the products is higher, but the defects of carbon nanotubes are more.
- Q:What's the purpose of the electrode material?When the electrolytic molten state of NaCl is said, what is the use of the graphite electrode and the iron electrode?
- 1. graphite (two kinds of EDM3 and EDM200)2. copperIn general, graphite electrode for extensive escape material (graphite texture loose, discharge energy is relatively large, removal of materials faster, but face flowers that roughness is relatively large
- Q:Excuse me, why does the graphite electrode flake when electrolyzed salt water is used?
- For example, according to connection of the electrode, which can be divided into two types of unipolar and bipolar type electrolyzer (see photo). The electrode is connected with the DC power supply parallel polarity monopolar electrolyzer, electrodes on both sides of the same, at the same time as anode or cathode. At the same time as the positive and negative electrode bipolar type electrolyzer ends respectively with DC power supply connected, as anode or cathode. The current through the electrode through the electrolysis cell in series, each side of the intermediate electrode as the anode, the other side is the cathode, so it has a bipolar electrode. When the total area at the same time, the current bipolar type electrolyzer is small, high voltage DC power supply, the required investment ratio monopolar, bipolar type filter press used. The general structure, more compact. But easy to leakage and short circuit, slot structure and operation management is more complex than the monopolar type. The monopolar electrolyzer section is generally rectangular or square, cylindrical covers a large, empty The utilization rate is low and the adoption rate is less
- Q:Can Naiduo high temperature graphite
- The reinforced graphite gasket is made of flexible graphite tape or flexible graphite and is molded into ring products of different sizes. Suitable for hot water, high temperature, high pressure steam, heat exchange liquid, nitrogen gas, organic solvent, hydrocarbon, low temperature liquid and other medium. Used in compressors, machines, pumps, valves, chemical instruments, instruments, etc..
