Q: Thermal conductivity and density of graphite powder: In the formula, P is porosity, and lambda 0 is the thermal conductivity without hole (P=0). This formula is of historic significance. For graphite, the pores are not spherical or more unequal, but of course they do not apply. But it shows that the larger the porosity (the smaller the density), the smaller the thermal conductivity. This qualitative conclusion is correct.

Q: Can graphite powder be used in lithium batteries?: Qingdao Huatai graphite more than 20 years experience in the production of graphite powder to tell you that graphite powder can be used in lithium batteries.

Q: How to identify iron powder and graphite powder in a simple way?: Iron powder can be attracted by magnet, graphite powder can not; iron powder can react with acid, graphite powder can not wait, optional take first magnet attract, and then drip acid or hand touch method to identify two substances;

Q: Is graphite powder dangerous?: Will pour into the dry drying workshop, drying after bagging, namely ordinary graphite powder, the carbon content of the finished product is 90%.x0d on average use making pencil graphite electrode, battery, cable lubricant morphological characteristics of a dark metallic luster and opaque fine flake graphite solid. Very soft, creamy sense.

Q: Like the wolf, adding graphite powder in the failure of electronic instrument air explosion in aircraft rocket season, really make it: The graphite bomb is real, but the main is to destroy the enemy power plant and other fixed objects, the damaged helicopter is unlikely, because the rocket explosion scope is limited, that not what eggs with graphite. It's better to use a bullet warhead than a graphite warhead.

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: How to measure the iron content in graphite powder?: Take a certain amount of samples, adding dilute hydrochloric acid, excessive filtering and drying. The quality of the filter residue. By weighing the quality of the sample quality is the quality of minus slag containing iron. With this value divided by the sample quality, the mass fraction of iron.

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: 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: Is the graphite powder produced with sulphuric acid?: Not only by crushing crusher can achieve, such as high purity stone toner, expanded graphite by sulfuric acid and other chemical methods for purification, preparation and so on
