- Q: Is graphite electrode good for foreign trade?
- Foreign sales commission depends on the price you talk to the customer, and the profit is objective.
- Q: Why is graphite conductive electrode oxidized?
- The reason for its oxidation is that it is oxidized at atmospheric temperature by reacting with the oxygen in the air
- Q: What are the skills of hardfacing process for wear-resistant alloy powder blocks?
- The power supply adopts the DC arc welding machine with steep drop characteristic, adopts the positive connection method, the electrode is negative, and the electrode is a high strength spectrum pure graphite rod,
- 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: Which department in the steel plant needs graphite in large quantities?
- The variety and specifications of graphite electrodes used in modern EAF steelmaking are mainly determined by the technical parameters of the steelmaking furnace. With the development of EAF steelmaking technology, the steel-making technology is developing towards large scale and ultra high power. The graphite electrode is mainly made of large size graphite electrode and ultra high power graphite electrode.
- Q: What kind of asphalt is better for natural graphite coating?
- Graphite anode is mainly made of petroleum coke as raw material and coal pitch as binder. It is made by calcination, batching, kneading, pressing, roasting, impregnating, graphitization and machining. Conductive anode used for electrolysis equipment in electrochemical industry. Including: (1) anode plate for various chemical industries. (2) all kinds of anode rods.
- Q: Can Naiduo high temperature graphite
- Graphite gasket medium: hot water, steam, oil, acid, alkali, ammonia, hydrogen, organic solvents, hydrocarbons, cryogenic liquids, etc..Maximum use pressure of graphite gasket: 30MPa.Service temperature of graphite gasket: -200~650
- Q: How should carbon deposits be treated?
- At certain temperature, can make alloy and carbon can react in the engine surface coated with a layer of graphene film, graphene nano particles can fill the pores, wear scratches, on the friction surface repair function.
- Q: I used 12V direct current, graphite electrode electrolysis sodium sulfide solution, the anode produced a large number of black material, this is why ah?
- The problem is this. I have done the test of electrolytic copper sulfate, and the anode produced the same phenomenon. Finally, the chemistry teacher told me that it was because the graphite was broken in the process of electrolysis
- 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
