- 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: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:Antistatic concrete with graphite powder and conductive carbon black, which effect is good?More specific. I don't quite understand
- With graphite powder, the specific explanation is some chemical principle not elaborate
- Q:What solvent can be used to dissolve Teflon?
- PTFE is not dissolved after Teflon, it is impossible to mix with graphite powder this thing.
- Q:Main ingredients of graphite powder?
- In nature there is no pure graphite, which often contains SiO2, Al2O3, FeO, CaO, P2O5, CuO and other impurities.
- Q:Can graphite powder be used in lithium batteries?
- Because graphite powder is an important raw material for lithium battery production, graphite powder has conductive use, and graphite powder in conductive graphite powder is used to produce negative electrode materials for lithium batteries. Hope to help you, I hope to adopt, thank you.
- Q:For thermal grease skills, the more detailed the better
- But this is not possible, the metal lid heat sink and CPU looks smooth, but with a magnifying glass, you can see many holes in metal surface concave stripes and irregular tunnel, lead contact surface with many gaps, these gaps are impeding heat dissipation, thermal grease is liquid, can fill the gaps. Improved radiating surface contact, the heat dissipating effect than when there is no good thermal grease. But if the thermal grease is too thick, it will become a film on the contact surface of the middle, but hindered the direct contact of metal, worse than not coated with thermal grease.
- Q:What effect does graphite powder and graphite gas have on people? Also, I smell graphite gas as if I can't breathe. What's the harm to people?
- This is determined by the quality of the graphite powder. Graphite workers in our factory are equipped with masks to prevent dust. (formerly, Shandong, South villa, graphite mine) more than 5000 state-owned enterprises, workers have worked for 20-40 years, and has yet to find too much harm to the body. Pay attention to dust protection measures.
- 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 mask should be used to prevent stone powder?
- As an enterprise employee, we must actively advocate the right of labor protection to the enterprise owner, and the stone powder can be worn with industrial masks
