Natural Flake Graphite Powder

Q:Can graphite powder be found in plastic?: Graphite powder can be used in plastics, plastics are not resistant to wear, high temperature, acid and alkali corrosion, plastics are widely used in industry

Q:What is the industry standard of graphite powder coating for casting?: The two is fine, the finer the better, generally with the "eye" as a unit, that is, sieve stone toner used in the screen, square inch area included in the number of holes, the larger the number the better.

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: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?: Suggestion: use a certain amount of concentrated nitric acid infiltrated graphite part, nitrate solution the best there is a certain amount of 1-2 weeks (timing can also be placed with a glass rod, pour stirred) acid, diluted with water to acid and then scrub brush. Because the temperature nitric acid reaction is very slow, but the long-term infiltration, the graphite surface. Especially with the glass contact surfaces may be immersed in a small amount of acid, oxidation, then scrub may have the effect.

Q:Where are the graphite powders sold?: Graphite powder is a kind of non metallic mineral, and graphite powder can substitute carbon powder for a great extent

Q:What's the conductivity of graphite powder, silver powder?: These two values show that the resistivity of silver is small, so the conductivity of silver powder is better

Q:How does graphite powder look good or bad?: High quality graphite powder has high carbon content, superior performance, good quality and wide application range. This is the reason why the quality of graphite powder is higher than other graphite powder.

Q:Graphite powder made of graphite oxide, how much weight gain?: 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: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:Method for identifying iron powder, aluminium powder and graphite powder: 1. aluminum powder is silver, black substance attract rest with a magnet that attracted iron, not be attracted to the graphite2. Add equal mass, such as concentration of dilute hydrochloric acid, the gas is fast aluminum powder, slow iron, and do not produce gas is graphite.
