$Flake Graphite Powder for Refractories Made in Qingdao City China$

Q:Why does the temperature rise when the graphite powder is turned on?: The presence of resistance, melting point at 3850 + 50 degrees C, graphite powder is a very sensitive chemical substances, in different circumstances, his resistivity will change, that is, his resistance value will change

Q:Distinguish iron powder and graphite powder by chemical method: This problem is very simple, the use of chemical methods to distinguish: there are many ways to give me introduce you to some here, one plus HCl for Fe+HCl=FeCl2+H2, C and HCl reaction, 2: they were put into CuSO4 solution, can replace the red metal iron, whereas C

Q:Graphene with graphite powder where to do ah, high carbon content of the?.: Look at the document, 45 microns will do. Good to buy. Preferably expanded graphite. But then again, if you buy graphite as graphene... The difficulty is not small

Q:What is the ratio of the coated sand to the graphite powder? How to improve the refractoriness of precoated sand: General additives accounted for 0.1-0.5 of the original sand weight. Different demand, of course, the proportion is not the same, there is no fixed number.

Q:Will dust explosion occur in graphite dust? If you have definite or negative judgment, please share it according to data.: Any object that is crushed will have a surface energy (internal energy), but the temperature will not increase, so the specific heat will become largerFuel burns because its energy is already full (reaching a point of fire)When the object reaches the ignition point, internal energy = (ignition +273.15) * specific heat capacity

Q:The axis and drum can use graphite powder lubrication: No, graphite powder is suitable for high temperature environment, and the lubricating effect is better than that of lubricating oil

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:What does composite graphite mean?: It is an ideal sealing material and is widely used in sealing field. Composite graphite is a kind of graphite composite made of graphite powder and rubber plastic and resin. It can increase the conductivity and wear resistance of rubber and plastics, and can be applied in the field of electric conduction.

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: The only way to do this is by using physical methods, high temperature and high pressure, to agglomerate the graphite powder from the molecular level. Now, by simulating the high temperature and pressure of the earth's crust, graphite can be turned into diamond (that is, diamonds)

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.
