Q: Whether the ordinary graphite powder is sprinkled on the electronic instrument can lead to the malfunction of the instrument: Graphite powder mainly high pure graphite, graphite powder, nano graphite powder, each is toner has a specific map, if abused, graphite powder will have a certain impact on the letter together, Ruida professional build thermal field | graphite graphite graphite | | isostatic graphite graphite mold, hope this the answer can help to you

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.

Q: Are sand and particle powders used for casting quartz sand? Detailed and accurate.: Not necessarily. It depends on what product you make to determine what sand or powder you use

Q: The principle of a graphite missile: Graphite conducts graphite on the wire to short-circuit the circuit

Q: Can graphite powder be used for concrete?: Generally, stone toner is not used for concrete.There is no standard used or not used in this respect.Individuals believe that in order to form black concrete, it is feasible to add a small amount of graphite powder to concrete, but it should be proved to be in conformity with concrete standards and shall be reported to the business management department for approval. In other cases, even graphite powder can be used for concrete and is also a waste of resources. From the point of view of resource saving, graphite powder should not be used in concrete.

Q: What companies use graphite powder, graphite particles, graphite ball, silicon carbide alloy ball?: Refractory industry, because of the high temperature resistance of graphite and silicon, it will be applied in refractory industry.

Q: What is the simple test method for graphite powder used in casting?: Now the domestic inspection method of carburizing agent is the national standard of coal inspection method, the specific test of carbon content, volatile content, moisture, ash, sulfur and so on. The easiest way is to draw on the paper, drawing trace smooth, obvious is not obvious graphite products, may be coal or petroleum coke graphite the powder

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: Influence and protection of graphite dust on electrical equipment in workshop: Graphite powder is very easy to cause static electricity and short circuit, especially for the weak point, the graphite powder must be filtered out, or the electric distribution box is placed separately.

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.
