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: What's the conductivity of graphite powder, silver powder?: The resistivity of silver is about 1.6*10-8.M at room temperature

Q: How does graphite powder look good or bad?: The graphite powder is soft, black and gray, greasy and polluting paper. Hardness is 1~2, along the vertical direction with the increase of impurities, its hardness can be increased to 3~5. The specific gravity is 1.9 ~ 2.3. Under isolated oxygen conditions, the melting point is above 3000 degrees Celsius and is one of the most refractory minerals. At room temperature, the chemical properties of stone toner are relatively stable, insoluble in water, dilute acid, dilute alkali and organic solvents. The material has high temperature resistance and conductivity, and can be used as refractory materials, conductive materials, wear-resistant and lubricating materials.

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: 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: Why should the lubrication of automobile leaf springs be made of graphite grease?: This ultra high temperature grease in high temperature above 200 DEG when the base oil volatilize slowly, will be attached to the graphite solid lubrication lubrication is formed on the surface of graphite, itself is a kind of solid lubricant for heavy load / load impact or damp / high temperature friction parts and bearing lubrication under the pollution of the environment, to provide maximum anti rust corrosion protection

Q: Crystal graphite of graphite powder: Pure graphite flake graphite and high directional pyrolytic graphite, which have less defects and larger sizes, can generally be considered as perfect graphite single crystals. Considerable research has been done on the thermal conductivity of such graphite. Under compressive stress, the pyrolytic graphite above 3000K processing, the bulk density is 2.25g/cm, 2.266g/cm is close to the theoretical density of the single crystal, the half width of the diffraction peak (002) show only 0.4 degree angle (mosaic angle), is also very close to the theoretical value of zero. The thermal conductivity of this graphite is shown in table 1. These values are generally considered to represent the corresponding values for single crystal graphite. The thermal conductivity along two principal directions is denoted as lambda a along the layer, and is marked by lambda C along the vertical plane.

Q: Is the graphite powder produced with sulphuric acid?: Graphite powder can smash through physical production method, also can be produced by sulfuric acid and other chemical methods, according to different types of graphite powder, the production process is not the same, I hope there is help for you, hope to adopt, thank you.

Q: The processing technology of graphite powder is different, will the price of graphite powder be different?: The transportation cost of graphite powder is different: in different areas, transportation costs and prices are different, which will lead to more change in the price of graphite powder.

Q: What kinds of graphite powder has it? What's the function?: Its main use focuses on sealing and lubrication, and stone toner is powder, is the basis of other graphite products
