- 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:How do graphitized electrodes differentiate between high power and low power?
- 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
- Carbon nanotube discharge using graphite electrode is one of the earliest studies in various synthetic techniques. The researchers did a lot of work in optimizing arc discharge for carbon nanotubes. In recent years, in addition to people by adjusting the current and voltage, pressure and velocity change, change the electrode composition, improved electrode feeding mode optimization of arc discharge process, but also through changes the arc medium, simplified arc device. In the process of preparing carbon nanotubes, arc method is mature by changing the arc discharge conditions, catalyst, electrode size, feed mode, the distance between the poles and the raw materials. The carbon nanotubes formed by arc method are straight and wall (multi wall or even single wall). But the production rate is low, the arc discharge process is difficult to control, and the preparation cost is too high. The industrial scale production needs to be explored.
- Q:MITSUBISHI machine graphite electrode processing, how does not accumulate carbon?
- The three is difficult cold start, is sparking difficult, not easy car, and finally the combustion chamber carbon Yan will cause a heavy cylinder knock, low speed and acceleration noise, causing damage to the piston and crankshaft, causing the engine temperature which can seriously affect the automobile safety. Emission standards exceeded, not only through the annual inspection, but also directly aggravate the pollution of the environment
- Q:National standard for graphite electrodes
- Page 7 the international standard specifies the shape, dimensions and tolerances, technical requirements, test methods, packaging, marking, storage, transportation and quality certificates of graphite electrodes. This standard applies to high quality petroleum coke, asphalt, coke as the main raw material, through molding, roasting, impregnation, graphitization and mechanical processing made of, power supply arc furnace as conductive material of ordinary power graphite electrode. Common power graphite electrode GB
- Q:Why use platinum ferroalloy instead of iron as electrode?
- Silica (Silica) is widely used in paint, ink, plastic, rubber and cosmetics, are often added to increase the performance of silica, such as oil absorption, extinction, strengthen the mechanical... Etc., and can reduce the cost of...
- Q:How to solve the problem of graphite electrode being crushed during electrolysis
- There's no way. It's an industrial problem, and that's how graphite works.
- 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.
- Q:The graphite electrode made by the machining center adopts cooling method, which is water cooled, oil cooled and blow cold. Which is good?
- I had worked on graphite electrodes for 3 years before, and the fact told me that in addition to using the wind to remove the powder, the others were ineffective or disorderly. Because you have to measure size while processing.
- 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
