- Q: It's hard to remove a lot of graphite powder on the glass cake. Who has a good way to remove the graphite powder above?
- Suggestion: use a certain amount of concentrated nitric acid infiltrated graphite part, nitrate solution the best there is a certain amount of 1-2 weeks (timing can also be placed with a glass rod, pour stirred) acid, diluted with water to acid and then scrub brush. Because the temperature nitric acid reaction is very slow, but the long-term infiltration, the graphite surface. Especially with the glass contact surfaces may be immersed in a small amount of acid, oxidation, then scrub may have the effect.
- Q: The principle of a graphite missile
- When graphite sticks to point wires, numerous circuits are formed, but they are short circuited.So the circuit was broken.
- Q: Where are the graphite powders sold?
- Graphite powder is a kind of non metallic mineral, and graphite powder can substitute carbon powder for a great extent
- Q: Method for identifying iron powder, aluminium powder and graphite powder
- 1. with a magnet and dilute hydrochloric acid!2. direct use of hydrochloric acid, aluminum powder, gas faster; iron powder moderate; graphite powder does not respond!
- Q: Use of carburizing agents
- In the smelting process, due to improper ingredients or improper loading and excessive decarburization, the carbon content in the steel sometimes does not meet the requirements of the top stage. The commonly used carburizing agents include carburized pig iron, electrode powder, petroleum coke powder, charcoal powder and coke powder. When smelting medium and high carbon steel in converter, the oil containing little impurity is used, and Jiaozuo is used as carburizing agent. For BOF steelmaking using recarburizer requirement is high to low fixed carbon, ash, volatile matter and sulfur, phosphorus, nitrogen and other impurities, and dry, clean, moderate size.
- Q: Can graphite be made directly from graphite powder? How about the effect?
- Because of the low activity of graphite powder, a kind of binder is needed.
- Q: Are graphite powders soluble in water, dilute acids, dilute bases, and organic solvents?
- Under heating, the graphite powder is more easily oxidized by acid. At high temperature, it can react with many metals to produce metal carbides, which can smelt metals at high temperature
- Q: Why is there a range of electrode powder powder resistivity? The reasons for the high and low are not good.
- A cylinder is inserted in the pipe, and the cross section of the pipe is slightly smaller than the inner diameter of the sample tube. The lower cylinder is fixed on the base of the instrument, and the upper cylinder can move up and down in the tube as a prop to pressurize the sample. The sample is located in the insulating casing on the cylinder between the positive and negative pole and galvanometer millivoltmeter are respectively connected to the drum two cylinder, rotary measuring height, driven by the leading screw rod lifting rod to balance, balance level, sample by 3.92MPa pressure, then switch on the current, the current adjustment into the sample to 300mA, then open the switch millivoltmeter,
- Q: Two simple physical methods are used to identify iron powder and graphite powderHurry up, you need it urgently! Thank you
- A magnet attracts iron powder... Take the same volume of two substances, respectively, in the hands of weighing, the heavier iron powder
- Q: Are graphite and carbon black the same?
- The difference is great, although graphite and carbon black are of the same kind
