- 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: Use of carburizing agents
- The particle size is too fine, easy to burn, too coarse, float on the surface of liquid steel after adding, and it is not easy to be absorbed by steel. The particle size of 0.2-6mm in the induction furnace, the steel and other ferrous metal particles in 1.4-9.5mm high carbon steel, low nitrogen, particle size in 0.5-5mm, and according to the specific needs of the furnace smelting specific types of workpiece so the details of specific judgment and selection.
- 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: The difference between silicone and silicone?
- The characteristics of silicone grease:The application of silicone grease is more widely than silica gel. Many industrial heat places are using thermal grease. Many different types of people and grease, by adding some "impurities" to its thermal conductivity to improve pure thermal grease. These impurities are graphite powder, aluminum powder, copper powder, silver powder and so on. Pure pure silicone is pure white or milky white, the color of the doped graphite grease dark black, doped with aluminum grease some gray shiny, slightly gray is silver, and copper doped grease are yellow or yellow.Now some high-grade thermal grease using silver or aluminum powder as filler, with high thermal conductivity of the metal, but relatively large metal particles, filling effect is poor, the performance increase is not large, but the improper use of conductive grease, easy to cause a short circuit.
- Q: The graphite powder production process and the graphite production process are introduced briefly Graphite powder production process, graphite production process, detailed technical parameters where?
- In the process of crushing, the external force applied to the solid has four kinds of rolling, shearing, impact and grinding.
- Q: How to measure the iron content in graphite powder?
- Excessive amounts of dilute sulphuric acid can be used to measure the amount of gas produced, and then the amount of iron is calculated according to the amount of gas.
- 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: Main ingredients of graphite powder?
- These impurities often appear in quartz, pyrite, carbonate and other minerals.
- Q: Does the graphite powder cause explosion? If so, how to prevent the production of graphite products in the workshop?
- Flammable dust is suspended in the air at an appropriate concentration to form dust clouds that are commonly called;All the solid matter which is fine powder is called dust. The dust that burns and explodes is called combustible dust; the dust floating in the air is called suspended dust; the dust deposited on the solid wall is called sedimentary dust.With explosive dust: metal (such as magnesium, aluminum); coal; grain (such as wheat, starch); feed (such as blood meal, fish meal); agricultural and sideline products (such as cotton and tobacco); forest products (such as paper powder, wood flour); synthetic materials (such as plastics, dyes).
