Usage

Nature Flake Graphite for Refractory Materials with Good Quality

Crystalline flake graphite is widely used as an essential nonmetallic material in almost all industries. It can be used as high quality refractory material or coatings in metallurgical industry, black lead in light industry, and carbon brush in electronics industry, electrode in battery industry and catalyst in chemical fertilizer industry. After being deep processed, crystalline flake graphite can be used to produce TV tube coatings, graphite friction reducing additives and many other high tech product

Q:Does the pencil core go into the baby's face to keep the skin tight?: If there were no broken ends to stay inside and squeeze a little bit of blood out, the problem would not be serious. If you have broken ends, you'd better go to the hospital.

Q:How much is the price of graphite powder for a ton?: Qingdao Chenyang graphite is China's Graphite brand-name products, strong technical force, perfect measuring and testing, quality assurance system.

Q:Is graphite powder conductive?: The bottom current may be the internal resistance of the battery is too large, in addition to graphite reasons, the contact state of battery cathode and graphite copper check, graphite powder, no contact measurement, the conductivity of no experience, resistance measurement of graphite column can be compared (with the current large and small current comparison test),

Q:Crystal graphite of graphite powder: At room temperature, lambda A is about 200 times larger than lambda C. As the temperature increases, this ratio decreases, but remains large. Therefore, the thermal conductivity of polycrystalline graphite composed of microcrystalline is controlled by the thermal conductivity of microcrystalline layer lambda a, and lambda C can hardly be considered. The lambda a of natural flake graphite is between 280 and 500W/ (m * K) at room temperature. The ratio of lambda a/ lambda C is between 3~5, so the perfection of crystal is far better than that of high directional pyrolytic graphite.

Q:Can I use super fine stone powder in grease or lubricating oil?: Yes, it can play a role in increasing extreme pressure. But it has little effect on low temperature and high temperature resistance. It can not play the role of total synthesis of molybdenum disulfide high temperature grease.

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: There is no binder that can withstand 1000 degrees C. At such a high temperature, any binder has been carbonized and has lost its bond effect, so it is impossible if you want to use the binder to make the graphite powder into pieces

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:How can graphite paper be made? Can graphite powder be solidified without brittleness?: Process for the preparation of graphite paper: high carbon flake graphite, graphite by chemical processing into acid (also known as graphite oxide or expandable graphite), in high temperature 960 to 980 DEG C for a few seconds, the level of the graphite lattice moment along the C axis expansion, a fiber floc type vermicular graphite. The expanded graphite is very soft, the roller for the rolling forming, expanded graphite and flexible graphite sheet or foil sheet.

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:What is special graphite powder used in graphene?: In terms of hardness, diamond is of great hardnessI see your supplementThat part of the encyclopedia is wrongThe advantage of graphene is that its hardness is great compared to other materialsBut you can't compare with diamond
