Q:How to distinguish between iron powder, aluminum powder and graphite powder (pencil core powder), there are two ways: Method three: in reverse order with method(1) take a little powder and add dilute hydrochloric acid respectivelyIf bubbles are produced and green light is generated, the solution is iron powder (chemical equation Fe+2HCl = FeCl2+H2)The reaction is more intense, there are more bubbles, the color of the solution does not change, it is aluminum (chemical equation 2Al+6HCl = 2AlCl3+3H2)No obvious phenomenon is graphite powder (not reaction)(2) if the difference between the bubble phenomenon is not obvious, then two kinds of powder with magnetCan be the magnet is not attracted by the permanent magnet is iron powder; powder(high school can also use NaOH solution to identify iron aluminum, aluminum reacts to dissolve hydrogen, iron does not respond)

Q:Does graphite allow lubrication of rusted doors?: Sure。 When we were young, the teacher reminded us that we could use the pencil core to scrape the end and put it into the keyhole to lubricate it.

Q:Antistatic concrete with graphite powder and conductive carbon black, which effect is good?More specific. I don't quite understand: Suggested carbon blackBecause of the good lubricity of graphite, the addition of graphite will increase the lubricity of the concreteIn addition, compared with the same amount of graphite and carbon black, the volume of carbon black is larger, the surface area is also large, the contact area increases, and the conductive network is easier to formFirst of all, I hope I can help you

Q:The principle of a graphite missile: Graphite conducts graphite on the wire to short-circuit the circuit

Q:The graphite powder production process and the graphite production process are introduced briefly Graphite powder production process, graphite production process, detailed technical parameters where?: In the process of crushing, the external force applied to the solid has four kinds of rolling, shearing, impact and grinding.

Q:How to measure the conductivity of powdered graphite?: Some other factors for measuring the resistivity of conductive graphite powderConductivity varies with external factors and is sensitive. The early microphones were made with graphite powder, because the vibration of the voice changed the electrical conductivity between the graphite powders and changed the current to produce analog signals. One can imagine that you need to test his electrical conductivity for the experimental environment.

Q:Sunshine door lock winter treatment: When the lock is in use, a small stone powder or pencil powder can be put in the lock core slot for regular (half a year or year) or when the key is not inserted smoothly, so as to ensure that the key is inserted and inserted smoothly. But avoid adding any other oils to lubricate to prevent grease sticking to the spring, causing the lock to rotate and not open.

Q:Can ultrafine powder iron conduct heat? How many purpose graphite powder can be called superfine stone powder? Pingdu graphite powder which good?: Ultrafine toner is a thermal conductive function, because ultrafine toner is processed from natural graphite, which inherits the characteristics of natural graphite conduction and heat conduction.

Q:Whether the lubricating oil toner is coupled with the conductor?: Not really. It depends on the amount of graphite powder. If the graphite powder forms a continuous through zone, it can be considered a conductorYou can use lubricating oil, preferably not with graphite, which will cause the sliding rheostat to fail

Q:Know how the colloidal graphite powder comes in: Colloidal graphite is a kind of nano material of graphite. The particle size between 1 and 100 nm is called colloidal graphite.Colloidal graphite prices are mainly based on the grain size and carbon content to develop, according to the amount of carbon graphite into high purity, high and medium carbon and low carbon four files, each grade of the difference between the price of a large, but since processed into colloidal graphite, then the carbon content of high carbon should at least be above, if there is no way know the amount of carbon it can only roughly estimate the price of 4-6 million / ton, if it is pure graphite (carbon 99.9%-99.99% above) the price is at least 100 thousand / ton
