Q:Use of carburizing agents: In the smelting process, due to improper ingredients or improper loading and excessive decarburization, the carbon content in the steel sometimes does not meet the requirements of the top stage. The commonly used carburizing agents include carburized pig iron, electrode powder, petroleum coke powder, charcoal powder and coke powder. When smelting medium and high carbon steel in converter, the oil containing little impurity is used, and Jiaozuo is used as carburizing agent. For BOF steelmaking using recarburizer requirement is high to low fixed carbon, ash, volatile matter and sulfur, phosphorus, nitrogen and other impurities, and dry, clean, moderate size.

Q:Are graphite and carbon black the same?: The difference is great, although graphite and carbon black are of the same kind

Q:Will dust explosion occur in graphite dust? If you have definite or negative judgment, please share it according to data.: Dust explosion condition(1) flammable dusts are suspended in the air at proper concentration to form dust clouds which are often called;(2) adequate air and oxidizing agents;(3) there is fire or strong vibration and friction. Generally believed that the explosive dust as long as the conditions (1) and conditions (2), it means that there are possible signs of the accident.

Q:What's the conductivity of graphite powder, silver powder?: The resistivity of graphite is approximately (8~13) * 10-6.M at room temperature

Q:What mask should be used to prevent stone powder?: As an enterprise employee, we must actively advocate the right of labor protection to the enterprise owner, and the stone powder can be worn with industrial masks

Q:The difference between silicone and silicone?: Characteristics of silica gel:Silica gel is a one component, room temperature vulcanized liquid rubber. Once exposed to air, the silane monomer condensed, forming a network structure, crosslinked, unable to melt and dissolve, elastic, rubbery, and adhesive. The thermal conductivity is slightly higher than the general rubber, but compared with the thermal grease is much lower, and once cured, it is difficult to separate the adhesive objects, generally can only be used in graphics cards, memory radiator. Mainly used in silicone adhesive low-end card heat sink and the main chip, bonding and particles, particles of the memory memory and radiator. The high-end products are generally used to dissipate heat with grease, and then use the clip fins fixed on the substrate, but it will increase the cost of. The radiating fins are fixed in the low-end graphics chip and good memory particles, and the heat sink in the low-end graphics cards generally are relatively small, so the use of silicone adhesive is common; and high-end graphics and the CPU heat is far greater than the general low-end graphics chip and memory particle heat generation, and the head is relatively CPU so, the grease with radiator and clip form. If used on the CPU will cause overheating, and it is difficult to remove the heat sink, pull down, it may directly damage the CPU or CPU socket. And if you pull down the silicone adhesive cards, heat sink, it is possible to display the chip from the PCB pull down. From this point, we can see who has a better heat conduction effect.

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?: This is determined by the quality of the graphite powder. Graphite workers in our factory are equipped with masks to prevent dust. (formerly, Shandong, South villa, graphite mine) more than 5000 state-owned enterprises, workers have worked for 20-40 years, and has yet to find too much harm to the body. Pay attention to dust protection measures.

Q:Why should the lubrication of automobile leaf springs be made of graphite grease?: This ultra high temperature grease in high temperature above 200 DEG when the base oil volatilize slowly, will be attached to the graphite solid lubrication lubrication is formed on the surface of graphite, itself is a kind of solid lubricant for heavy load / load impact or damp / high temperature friction parts and bearing lubrication under the pollution of the environment, to provide maximum anti rust corrosion protection

Q:What is graphite powder?: Graphite powder chemical reaction is very sensitive material, in a different environment inside his resistivity would change, is also his resistance value will change, but one thing is not change, graphite powder is one of the non metal conductive material is very good, as long as the insulation inside the graphite powder to ensure uninterrupted, like a lines that will power, however, the resistance value is how much, this is not an accurate numerical number, because not the same as the thickness of graphite powder, graphite powder and materials used in environmental resistance of different values will be different.

Q:What is special graphite powder used in graphene?: Graphene special graphite powder is specially used for the development of graphene, graphene graphene from graphite powder is special in stripping out, universities and research institutions of graphene special graphite powder, graphite powder, graphene special quality of Qingdao Huatai provide very good, have a good reputation among colleges and universities, scientific research institutions in such help, hope to adopt L.
