Q: What's the conductivity of graphite powder, silver powder?: The resistivity of graphite is approximately (8~13) * 10-6.M at room temperature

Q: How can the clinker graphite powder be dissolved in water?: To achieve this purpose many methods; the titanate coupling agent and silane coupling agent is used in simple water dispersion system of the surface modification, hydrophilic group will make Shi Mofen (film) dispersed in water while stirring under shear stress.

Q: How to identify iron powder and graphite powder in a simple way?: Can also take the first touch, using magnets to attract or drop method with acid identification of three substances. [a] analytical method (first touch after magnet): touch the two kinds of powder by hand, are oily powder graphite powder, and then take the other two kinds of powder with a magnet, the magnet can be as for iron, can not be sucked up into powder;

Q: What if the key is inserted in the hole and can not be drawn out?: This is not a simple question, to the dorm there, there will be someone to help you repair

Q: How to measure the iron content in graphite powder?: Excessive amounts of dilute sulphuric acid can be used to measure the amount of gas produced, and then the amount of iron is calculated according to the amount of gas.

Q: What solvent can be used to dissolve Teflon?: PTFE is not dissolved after Teflon, it is impossible to mix with graphite powder this thing.

Q: What companies use graphite powder, graphite particles, graphite ball, silicon carbide alloy ball?: Other industries, mainly the use of carbon components or graphite characteristics of the place.

Q: Why does an electromagnetic point timer not prick a needle and use toner paper?: It's a combination of graphite powder and current to mark the surface of the tape. You can imagine it as an inkjet printer

Q: Are graphite and carbon black the same?: But they are not the same as the atomic structure, physical properties are not the same, the graphite conductive carbon black than how many times, lubricating graphite is much higher than carbon black, graphite and carbon black light can be separated from these two points is not the same, there are more different places.
