- Q: Thermal expansion coefficient of graphite
- In the graphite electrode, the national standard, the volume density in more than 1.60 of both high power graphite electrode, of course because of the national standard index is low now, the volume density of normal power graphite electrode factory can reach 1.65, such as Chengde and long carbon factory.
- Q: Synthesis techniques of carbon nanotubes
- The synthesis techniques of carbon nanotubes are mainly arc method, laser ablation (Zheng Fa) method, catalytic cracking or catalytic chemical vapor deposition (CCVD), and directional control growth method based on various synthesis techniques.
- Q: The original battery is not necessary to form the electrode potential? Why can we use graphite as electrode only? No potential difference.
- External electronic wire and the directional movement of ions in the solution of the directional movement between the poles of a closed loop, so that the two electrode reaction, electron transfer process, ordered a current converting chemical energy to electrical energy.Attention, here, "the ion does not go ashore, the electron does not enter the water"." That is the external circuit of graphite electrode is composed of electron flow and electrolyte ion flow; graphite electrode is to produce voltage and electrolyte, and to provide or absorb electrons
- Q: How long is the graphite electrode machining cycle?
- Industrial graphite is hard and brittle, and the tool is worn more seriously during machining. It is generally recommended to use carbide or diamond coated cutting tools. When the graphite is rough, the cutter can be directly worked on the workpiece. When it is finished, it is necessary to use light knife to walk quickly to avoid the occurrence of chipping and chipping
- Q: What is the application of wire cutting with graphite electrode?
- With the development of science and technology, the machine manufacturing technology has undergone profound changes. Due to the social demand for diversification of products is more intense, more varieties, small batch production increasing proportion in WEDM by traditional processing equipment has been difficult to adapt to the processing of high efficiency, high quality, diversified requirements, CNC technology should be used
- 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..
- Q: How should carbon deposits be treated?
- It is very necessary to clean the throttle valve, clean the nozzle, and clean the carbon in the engine cylinder! However, in order to reduce the trouble of cleaning, it is best to join the regular application of graphene Moqi additive in lubricating oil for engine.
- Q: Classification of graphite electrodes
- 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 the steelmaking process of the poly carbon graphite electrode, prolonging the service life of the electrode (22%~60%), and reducing the electric energy consumption of the electrode. The popularization and use of this technology can bring about such economic and social effects:The unit consumption of graphite electrode is less, and the production cost is reduced.The power consumption of the graphite electrode is less, the energy consumption per unit of steelmaking is saved, the production cost is saved, and the energy saving is saved.Because the number of graphite electrodes is changed less, the labor quantity and danger coefficient of operators are reduced, and the production efficiency is improved.Graphite electrode is a kind of low consumption and low pollution product. It has a very important social significance in today's energy saving, emission reduction and environmental protection.
- Q: Iron and graphite as electrodes and Nacl as electrolyte solutions. Why do they produce electric current? Graphite and iron react not with solution, can they be connected by wires?
- Graphite here acts only as an electrode, and the real reaction on the graphite is oxygen, the galvanic cell reaction called iron oxygen corrosion
- Q: What is the composition of petroleum coke and what is its use?
- Petroleum coke can be used for the manufacture of graphite, smelting and chemical industries, depending on its quality. For example, the quality of cooked sweet coke coke, mainly used in the manufacture of ultra high power graphite electrode and some special carbon products; needle coke in steelmaking industry is an important material new technology development of EAF steelmaking.
