Q: What is the difference between pyridine type nitrogen and graphite type nitrogen?: The fine structure graphite is the raw material used in the production of graphite electrode. The particle size is relatively small, generally below 0.5.

Q: Why should the carbon brush for the trolley be made of graphite?: Graphite conducts electricity and is self lubricant, resistant to wear. As for why, high school chemistry textbooks have ah.

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: The reason is that the resistance increases continuously, the number of ions is limited, and the conductivity is limited

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: 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: 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: What's the use of carbon?: Oxidation resistant coating graphite electrode. A graphite electrode coated with an antioxidant protective layer is applied to form a protective layer that is conductive and resistant to oxidation at high temperature, thereby reducing electrode consumption during steelmaking.

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?: The copper electrode used for finishing size of the copper electrode discharge speed is not fast but spent graphite electrode is relatively smallRequirements of the high surface, the appearance of products are copper electrode discharge processingThe iron electrode is not clear enough to be used

Q: What are the losses in graphite electrode?: In EDM, discharge principle is to remove the workpiece material by using the tool and the workpiece anode spark discharge explosion, spark discharge is bidirectional, not only will the workpiece removal part, forming processing, will cause some loss of electrode. Electrode loss is one of the main causes of machining errors in machining, and is an important technical parameter affecting the accuracy and quality of EDM

Q: How about graphite electrode high-temperature oxidation resistant coating?: Heat resistant coating is generally able to withstand 300 degrees below the temperature, commonly used aluminum heat-resistant paint, high temperature resistance can withstand higher temperatures, such as 800 degrees or more, commonly used silicone heat-resistant paint

Our products have been sold to Europe, Southeast Asia, South America, India, and other countries and regions. Meanwhile, Our Graphite Electrodes and nipples have already been ISO9001:2000 approved. We will pay attention to product quality and offer you the best price. We hope that we could establish business relationships with all friends on the basis of equality and mutual benefits.
