Q:How do you use graphite powder in copper?

It is to drill holes on the copper block and pour the graphite into the hole to ensure that the stone toner can not run out and play the role of oil-free lubrication

Q:Refractive index and absorbance of graphite powder

Color changes indicate that the absorption of light inside the material has changed, it can not be compared by the size of the relative content of absorbance. By absorbance, the content must be of the same substance and comparable at the same wavelength.

Q:Are graphite and carbon black the same?

The difference is great, although graphite and carbon black are of the same kind

Q:Crystal graphite of graphite powder

The crystal structure of highly structured pyrolytic graphite, La above 2000Nm, from low temperature to high temperature, the thermal conductivity changes with the temperature is bell shaped, see Figure 1, figure 2.

Q:What if the key is inserted in the hole and can not be drawn out?

This is not a simple question, to the dorm there, there will be someone to help you repair

Q:Is the graphite powder poisonous?

Qingdao Huatai graphite for you to answer, graphite powder itself is no poison, graphite powder is powder, a long time in the graphite powder prone to pneumoconiosis and other occupational diseases, work should bring masks, ventilation conditions, eat more fungus and so on to prevent,

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:Influence and protection of graphite dust on electrical equipment in workshop

The graphite dust in the workshop is conductive, and the adhesion to the electric apparatus will affect the electrical insulation and lead to accidents. So we need to have the electrical box of graphite dust workshop to closed treatment, to prevent dust into the electrical cabinet.

Q:How to deal with graphite powder? Anyone recycle it?

We have a lot of graphite, and now we have it

Q:Whether the lubricating oil toner is coupled with the conductor?

Not really. It depends on the amount of graphite powder. If the graphite powder forms a continuous through zone, it can be considered a conductorYou can use lubricating oil, preferably not with graphite, which will cause the sliding rheostat to fail
