Q: Thermal conductivity and density of graphite powder: For the same type of graphite, the thermal conductivity increases with increasing density, and Figure 11 shows the relation between the density of HDFG and the density of the same graphite.The heat treatment temperature of polycrystalline graphite is mostly made by roasting the semifinished material by high temperature heat treatment. The higher the heat treatment temperature is, the more perfect the crystallite growth is, the La increases, and the thermal conductivity also increases. With calcined petroleum coke and coal tar pitch, roasting sticks made of extrusion, after different heat treatment (HTT), the value of La are shown in Table 4. The axial thermal conductivity will change with temperature is shown in figure 12. The reciprocal of thermal conductivity 1/ lambda is called thermal resistance. At different temperatures, the relationship between the axial thermal resistance of graphite is shown in Figure 13 and l/La / 1/.

Q: How to identify iron powder and graphite powder in a simple way?: According to the nature of the difference between the two substances: graphite powder has a greasy feeling, iron powder does not;

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: 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: 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: 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: Can graphite powder be used as a carburizing agent?: Basically can be, but to look at your purity, if many impurities can not be used if the carburant is a general term, is all can increase the carbon content of the material referred to a molten iron, graphite powder is then dust too much, when the operation is not clean, too small it is easy to burn and water oxidation, not good,

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

Q: How can graphite paper be made? Can graphite powder be solidified without brittleness?: Single layer graphite paper is thin, thickness less than 1mm, strength is low, it is the raw material of electric heating felt and advanced gasket sealing material. It is widely used. The single graphite paper and multilayer plate are rolled into thick composite boardI hope it works for you

Q: The axis and drum can use graphite powder lubrication: This doesn't seem good. Graphite powder is a solid lubricant. It is suitable for heavy equipment lubrication. The axis and drum or low viscosity lubricating grease is better, so fast.
