- Q: How does graphite powder solidify into a lump? What bond is best used?After solidification can be more than 1000 degrees high temperature does not change
- There is no binder that can withstand 1000 degrees C. At such a high temperature, any binder has been carbonized and has lost its bond effect, so it is impossible if you want to use the binder to make the graphite powder into pieces
- 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: How much is one graphite used as electrode?
- Graphite particles 6800 yuan / ton, graphite fine powder 8000 yuan / ton, you buy 30 yuan / kg is the natural graphite powder? Not made of graphite electrodes. The graphite powder used in the electrode is actually synthetic graphite powder.
- Q: Is graphite powder conductive?
- Qingdao Huatai graphite powder solution for you is a conductive graphite powder, graphite powder for non-metallic mineral matters, graphite powder has good conductivity, high temperature resistance, lubrication, thermal properties, graphite powder used in industry is very broad, conductive graphite powder can be made of conductive coating, battery the production of materials, conductive composite materials,
- Q: Method for identifying iron powder, aluminium powder and graphite powder
- 1. aluminum powder is silver, black substance attract rest with a magnet that attracted iron, not be attracted to the graphite2. Add equal mass, such as concentration of dilute hydrochloric acid, the gas is fast aluminum powder, slow iron, and do not produce gas is graphite.
- Q: The difference between silicone and silicone?
- The characteristics of silicone grease:The application of silicone grease is more widely than silica gel. Many industrial heat places are using thermal grease. Many different types of people and grease, by adding some "impurities" to its thermal conductivity to improve pure thermal grease. These impurities are graphite powder, aluminum powder, copper powder, silver powder and so on. Pure pure silicone is pure white or milky white, the color of the doped graphite grease dark black, doped with aluminum grease some gray shiny, slightly gray is silver, and copper doped grease are yellow or yellow.Now some high-grade thermal grease using silver or aluminum powder as filler, with high thermal conductivity of the metal, but relatively large metal particles, filling effect is poor, the performance increase is not large, but the improper use of conductive grease, easy to cause a short circuit.
- Q: Antistatic concrete with graphite powder and conductive carbon black, which effect is good?More specific. I don't quite understand
- But the conductive carbon black in plastic system can achieve better quality with less graphite is because in polymer systems, factors of conducting conductivity in addition to the conductive powder itself, but also with the distribution of conductive particles in the polymer related. The same quality of the carbon black and graphite carbon black, due to a smaller proportion, occupy a large volume fraction of the polymer, is conducive to the formation of conductive network, which was better than the effect of conductive filler graphite.But in the high aggregation state, the conductivity of graphite aggregate is much better than that of carbon black. The good conductive electrode material is made of graphite instead of carbon black.
- Q: How much is the price of graphite powder for a ton?
- Qingdao Chenyang graphite is China's Graphite brand-name products, strong technical force, perfect measuring and testing, quality assurance system.
- Q: Can graphite powder be used as a carburizing agent?
- You can consult the Qingdao permanent Carbon Industry Co. Ltd. is a professional, they do carburetant, buy their products never mind, you can consult, will give you a very good answer, their service is pretty good
- Q: Why can graphite powder conduct electricity?
- Dense crystalline graphite is also called massive graphite. These crystals are crystalline and visible to the naked eye. Particle diameter greater than 0.1 mm. The crystals are arranged in a dense and blocky structure. The graphite is characterized by a very high grade, general carbon content is 60 ~ 65%, sometimes up to 80 ~ 98%, but its plasticity and unctuousness as fine flake graphite.
