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: What is special graphite powder used in graphene?: In terms of hardness, diamond is of great hardnessI see your supplementThat part of the encyclopedia is wrongThe advantage of graphene is that its hardness is great compared to other materialsBut you can't compare with diamond

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: 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?: Graphite powder itself is harmless, and even eat nothing, you smell the so-called graphite powder can only be said to be in (high temperature) such as copper and aluminum smelting gas produced by graphite powder, graphite powder for sulfur, after high temperature will have a S taste great, as far as possible to avoid a long time.

Q: The difference between silicone and silicone?: Silicone grease and silica gel although only two words in the literal sense, and all the thermal materials, but two things is completely different. Relatively speaking, the scope of the grease has a slightly wider, need to fit almost any cooling conditions; and because the silica gel once it is stuck on difficult to remove, so most of the time is used in some occasions only need one-time adhesion, heat sink such as graphics memory and memory of the particle particle. The main use of silica gel is bonding agent. We need to buy is the main heat conduction effect of silicone grease, you can not buy the wrong.

Q: Like the wolf, adding graphite powder in the failure of electronic instrument air explosion in aircraft rocket season, really make it: Unable to do so, although the graphite can make cars, aircraft and other short circuit, but the aircraft is basically insulated, airtight, the engine is not affected. This is the need for film and television work.

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 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: The processing technology of graphite powder is different, will the price of graphite powder be different?: The transportation cost of graphite powder is different: in different areas, transportation costs and prices are different, which will lead to more change in the price of graphite powder.

Q: Does the graphite powder cause explosion? If so, how to prevent the production of graphite products in the workshop?: The graphite powder will cause an explosion. The production of graphite products in the workshop by means of centralized collection and fire protection to avoid explosion.The combustible dust explosion, dust explosion limits in encountered heat (fire or high temperature), flame spread instantly throughout the mixing space dust, fast chemical reactions, while releasing large amounts of heat, resulting in high temperature and high pressure, the system of energy into mechanical energy and light and heat radiation, has a strong destructive power. In the dust explosion with aluminum powder, zinc powder, aluminum powder, grinding a variety of plastic powder, organic synthesis of drug intermediates, wheat flour, sugar, wood, dyes, bakelite ash, milk powder, tea powder, tobacco powder, coal dust, dust and other plant fibers to produce production and processing places.
