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: Which shipping company can pick up the name of graphite? Graphite products are mainly exported to India, Italy and the United states!: Is mainly for a graphite export of dual-use technology permits other electronic key can not what Beijing permit the electronic key to table is generally 3-5 days of our electronic key you can apply for 2-3 months

Q: Does anyone know how to change graphite powder into graphite?! What kind of equipment do you need?!: Graphite powder, the first thing you should do is broken to a certain number of graphite powder, then add oil glue, is what we often say that the asphalt rubber, but imports of stone glue made less than impurities, suggest you use imported oil glue mixer, stir evenly into the mold machine with hydraulic pressure, hydraulic machine is 3000T this is a general, graphite block grinding pressure type, pressure oil well placed after the glue soak for seven days, and then go to the three or four roasting roasting, can be used, according to your different purposes, different adjustment process.

Q: Whether the lubricating oil toner is coupled with the conductor?: But with graphite, it will make the metal contact sheet and the whole resistance to form the passage, rheostat can not change the role of resistance. I actually lubricate, that is, with cotton swabs dipped in lubricating oil, and then put a touch on it.

Q: Graphite powder screening process, because with static holding together, resulting in vibration screen plugging network how to solve?: The other is to install an electrostatic eliminator when the material falls into the vibrating screen. When the material is dropped, the powder static electricity is removed and the mass will not be assembled again.

Q: What graphite powder made of graphite products, high hardness?! Wear-resisting！ Good moisture! It can be made into graphite products at 100-200 degrees high temperature: Graphite powder and resin mixing, molding, and then "high temperature" curing made graphite products, but the intensity of what will not be very high. Usually graphite products are not prepared directly with graphite powder, but with various kinds of coke, such as asphalt coke, petroleum coke, etc. the graphite products prepared by this method have high strength.

Q: Is the graphite powder poisonous?: There are three kinds of substances that fly out of the black spot from the carbon factory:1. Bituminous dust.2. A relatively fine particle of calcined coke (petroleum coke after calcination).3. A fine particle of calcined and graphitized Shi Mofen (calcined coke and bituminous mixture).Both poisonous.

Q: Crystal graphite of graphite powder: The crystal structure of highly structured pyrolytic graphite, La above 2000Nm, from low temperature to high temperature, the thermal conductivity changes with the temperature is bell shaped, see Figure 1, figure 2.

Q: What is the simple test method for graphite powder used in casting?: Mainly depends on its carbon content, hand stick a little bit on the white paper uniform, if there is a clear scratch is graphite powder

Q: Why can graphite powder conduct electricity?: Pure graphite in nature is not there, which often contains Si02, A1203, Fe0, CaO, P2O5, Cu0 and other impurities. These impurities often appear in quartz, pyrite, carbonate and other minerals. In addition, there are water, asphalt, CO2, H2, CH4, N2 and other parts of the gas. Therefore, the determination of graphite, in addition to the determination of fixed carbon content, but also the simultaneous determination of volatile and ash content.
