Q:The processing technology of graphite powder is different, will the price of graphite powder be different?
The supply and demand of graphite powder: the use of graphite powder is very extensive, so that the supply and demand of some areas is insufficient, which will make the price of graphite powder soar.
Q:Antistatic concrete with graphite powder and conductive carbon black, which effect is good?More specific. I don't quite understand
But the conductive carbon black in plastic system can achieve better quality with less graphite is because in polymer systems, factors of conducting conductivity in addition to the conductive powder itself, but also with the distribution of conductive particles in the polymer related. The same quality of the carbon black and graphite carbon black, due to a smaller proportion, occupy a large volume fraction of the polymer, is conducive to the formation of conductive network, which was better than the effect of conductive filler graphite.But in the high aggregation state, the conductivity of graphite aggregate is much better than that of carbon black. The good conductive electrode material is made of graphite instead of carbon black.
Q:What's the conductivity of graphite powder, silver powder?
The resistivity of graphite is approximately (8~13) * 10-6.M at room temperature
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: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: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. An extruded graphite core with different impregnation treatments
Q:It's hard to remove a lot of graphite powder on the glass cake. Who has a good way to remove the graphite powder above?
Just add some water and rub it over and over again with wooden sticks or bamboo strips. The effect will be better with water. Do not use hard objects such as glass bars, or your glass becomes a flower.
Q:Does graphite allow lubrication of rusted doors?
Into the rusty iron graphite powder can play the role of lubrication, graphite powder can open the door locks rust.
Q:Can graphite powder be used as a carburizing agent?
You can consult the Qingdao permanent Carbon Industry Co. Ltd. is a professional, they do carburetant, buy their products never mind, you can consult, will give you a very good answer, their service is pretty good
Q:Can graphite powder be found in plastic?
Can effectively improve these shortcomings of plastic, so graphite powder can be used in plastic, and I hope to help you, I hope to adopt, thank you very much.
