Q:What is electrical carbon?
The main component of electrical carbon material is carbon. Because of the different structures, carbon has two types: crystalline carbon and amorphous carbon. Crystalline carbon is mainly composed of graphite, amorphous carbon, mainly coke, charcoal, carbon black and so on. Coal used daily is an impure amorphous carbon.Graphite has a crystalline structure of six square system. It has numerous parallel layers superimposed on each layer of carbon atoms at the top angles of the six angles plane, forming an ordered arrangement of three-dimensional space. Because the distance between the layers of the graphite crystal is much larger than the distance between the carbon atoms on the surface, the graphite has an obvious anisotropy. When there is external force, the surface of graphite is easy to slip, so it shows self lubrication characteristics. In high purity graphite crystals, the valence band overlaps the conduction band, so the high conductivity of the metalloid is demonstratedThe arrangement of carbon atoms in amorphous carbon is haphazard, and it is easier to slip than the graphite layer, and its hardness is 4~5 times higher than that of graphite. Amorphous carbon, if treated at 2 200~2 5000C high temperature, can transform the disordered structure into an ordered arrangement of two-dimensional space.
Q:How dnf advanced carbon ashes?

Q:What are the advantages and disadvantages of carbon monoxide and carbon dioxide?
Carbon monoxide is a common poison, but trace use is good for organ transplants. British researchers have recently developed a new method that can effectively use carbon monoxide to help transplant organs survive, while avoiding the risk of carbon monoxide poisoning. Excessive inhalation of carbon monoxide poisoning will lead to death, carbon monoxide into the human body, and soon the hemoglobin in blood combined with the formation of carboxyhemoglobin, causes red blood cells to reduce the oxygen carrying, the tissue hypoxia in vivo. The cardiac and central biblical system is the most sensitive to hypoxia and the earliest affected. In the air of carbon monoxide concentration reached 117 mg / M 3, people can feel headache, vertigo: up to 292.5 mg / M 3 symptoms; up to 582.5 mg / M 3 will be nausea and vomiting, exhaustion, if not timely rescue can have life risk. When the concentration of carbon monoxide in the air reaches 11700 mg / M 3, a coma occurs; the concentration of carbon monoxide in the air reaches 1170 mg / m. The 3 spoons will soon die. This is bad. But in organ transplant operations, the use of trace amounts of carbon monoxide helps dilate blood vessels and reduce inflammation, thereby increasing the survival rate of transplanted organs.
Q:Isotopes of carbon
There are three kinds of nature of carbon isotope, stable isotopes of 12C, 13C and 14C 14C of the radioactive isotope, the half-life is 5730 years, the application of 14C mainly has two aspects: one is the determination of biological death in archaeology, radioactive dating method; the two is labeled with 14C compound as a tracer, exploration the micro motion of chemistry and life science.
Q:What do you mean by carbon fiber for 1K, 3K, 6K and 12K?
This is the specification of carbon fiber, refers to the number of filaments in carbon fiber tow, 1K=1000 (root), 3K=3000 (root), 6K=6000 (root), 12K=12000 (root). At the same time, 1K, 3K, 6K, and 12K are also called small tow.The relationship between the properties of carbon fibers and the number of filaments is described below:According to the number of carbon fiber bundle of carbon fiber filaments can be divided into small tow and tow two. Compared with small tow, the disadvantage of large tow is that when the structure of the plate is made, the tow should not spread out, resulting in the increase of the monolayer thickness, which is not conducive to the structural design. In addition, large tow carbon fiber adhesion, wire breaking phenomenon more, which makes the strength and stiffness of the affected, a decrease in performance, the performance of dispersion will be larger. Aircraft, spacecraft generally only a small tow carbon fiber, so the small tow carbon fiber is also known as the "space" of carbon fiber, large tow carbon fiber is known as the "industrial grade carbon fiber.But large tow production costs than small tow low, and with the progress of the production technology, people familiar with the structure of the carbon fiber material, large tow carbon fiber more and more stringent requirements for reliability field. In this way, between the small and large tow tow distinguish changes, such as earlier in the number of single tow 12000 (12K) as the dividing line, but the number of carbon fiber 1K~24K is divided into small bundles, rather than 48K designated as large tow. While the Airbus Company has begun to use 24K carbon fibers in the manufacture of A380 super large aircraft, it is estimated that as the technology advances, the line between the small tow and the big tow will push up.
Q:Carbon steel with carbon steel, carbon steel yuan yuan is the same? The trouble to know the answer urgently
For Fang Gang, bar, angle steel, steel, steel wire and other types. According to the shape of carbon structure round is carbon steel round. Especially carbon steel is often said in the past round. Such as 45# round steel. Carbon steel and carbon circle is not necessarily a variety.
Q:The similarities and differences of five existing forms of cementite in iron carbon alloy are analyzed
Two: cementite in iron graphite phase, carbon content more than 0.77%, in A (Fe + Fe3C) two-phase region precipitation of Fe3C is two times the cementite formation temperature in the eutectic temperature (1148 DEG C) and eutectoid temperature (727 DEG C), morphology of the mesh is a typical carbon content. From 0.77% to 6.69% is the typical composition range.
Q:What is carbon emission and what harm does it do? How can carbon dioxide be prevented?
Carbon deposition reaction:CH4 = kJ/mol C+H274.92CO = CO2+C +172.4 kJ/mol on.The main cause of carbon analysis is that the ratio of water to carbon is too low, so that the rate of carbon removal is lower than the rate of carbon depositionThe above chemical reactions are reversible reaction, from the analysis of thermodynamics, if the increase in temperature or reducing system pressure, increase the possibility of methane decomposition reaction type is CH4 C+H2 produce coke; possibility of CO reaction 2CO = CO2+C and CO = C + H2 reaction +H2O produce coke decrease. If the temperature is reduced or increased the pressure is on the contrary. The effect of temperature on coke reaction is very large, to avoid the [wiki] [/wiki] carbon catalyst must select the appropriate temperature, avoid carbon deposition area.
Q:How about carbon content of coal ash?
5. Fill in the records and present the report of the measurement result.6, in order to measure the accurate data, a sample should be tested in parallel with three crucibles at the same time, and the average of the results should be taken at last.
Q:How do you make the carbon ribs?
Use 1 tablespoons olive oil, 2 cloves of garlic, 2 tablespoons fresh Brazil, half lemon juice, 1 tablespoon Thyme, 1 jin spareribs, a little salt and black pepper method, 1. whole ribs washed, put the ingredients, marinated pork ribs 2 hours. 2., with charcoal fire roast ribs, while baking and brush ingredients, baked until golden. 3. if the oven can be placed in the oven 180C temperature, bake until golden
