Q:What is the ratio of the coated sand to the graphite powder?
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:Phosphoric acid, two aluminium hydride, with graphite powder and mud
Of a chemical bond, there is a certain minimum energy for molecules can break chemical bonds between the atoms, the energy corresponding to a critical wavelength, can make the chemical bond breaking in the wavelength of light irradiation.
Q:Why can graphite powder conduct electricity?
Graphite and diamond, carbon 60, carbon nanotubes are carbon elements, they are allotropes.Laixi, Shandong Province, is one of the important graphite producing areas in China. The proved graphite reserves are 6 million 871 thousand and 100 tons, and the reserves are 6 million 399 thousand and 300 tonsSoft, black, gray, greasy, dirty 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.
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: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.
Q:Graphite powder made of graphite oxide, how much weight gain?
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.
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 is the use of flake graphite in making flake graphite powder?
Better for corrosion protection coatings, fire retardant coatings and conductive coatings.
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:Like the wolf, adding graphite powder in the failure of electronic instrument air explosion in aircraft rocket season, really make it
If you want to hit the plane down, EMP is more practical! Besides, it is also expensive than with stinger!
