Q:The main difference between steel and iron is the difference in carbon content
The carbon content of 2% ~ 4.3% said that the iron carbon alloy cast iron. Iron is hard and brittle, but the pressure to wear. According to the existing steel carbon iron in different forms can be divided into white iron, gray iron and ductile iron. White cast iron with Fe3C carbon distribution, fracture is silver white, hard and brittle, not in mechanical processing, steel raw materials, it is also called the carbon graphite iron for steelmaking. The distribution of gray, gray fracture, easy cutting, easy casting, wear. If the carbon distribution is said to spheroidal graphite nodular cast iron, its mechanical properties and processing performance is close to steel special alloy elements added. In the cast iron can be special cast iron, such as adding Cr, the wear resistance can be greatly improved, with important applications in special conditions
Q:DNF advanced furnace rock carbon how, now more than +10 to advanced ah, how to get ah, 5
High-grade furnace rock carbon is in the previous time, Tencent limited, only the mall can buy! Now, the mall is off the shelf! It's already gone! Thank you!
Q:Is there a line cutting of carbon fibers?
Technical characteristics:1 、 high strength and high efficiencyTensile strength is more than several times of ordinary steel, and the modulus of elasticity is better than that of steel. It has excellent creep resistance, corrosion resistance and seismic resistance.2 、 light weight and good flexibilityCarbon fiber is of high strength and quality only 1/5 of steel. It has higher toughness. It can be rolled and can be supplied in larger length without lapping.3, the construction is convenient, the construction quality is easy to guaranteeMaterial without pre processing, convenient process, allowing cross plate.4, good durability and corrosion resistanceAcid, alkali, salt and atmospheric corrosion, and should not be maintained regularly.
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:Why is carbon content of stainless steel low?
This is because the main alloying elements of martensite chromium stainless steel is iron, chromium and carbon, such as Cr is greater than 13%, there is no gamma phase, such as single-phase alloy ferritic alloy, in any heat treatment system does not produce martensite, therefore must join the forming elements of austenite, Fe-Cr two alloy, to expand, C and N are effective elements, C, N elements adding alloy allows higher CR content. Chromium is one of the most important essential elements in martensitic chromium stainless steels, except chromium. In fact, martensitic chromium stainless steel is a kind of iron, chromium and carbon three element alloy C.However, the corrosion resistance of martensitic stainless steel mainly depends on the content of chromium, but the carbon in the steel due to the formation of stable chromium carbide with chromium, but also indirectly affect the corrosion resistance of steel. Therefore, in 13%Cr steel, the lower carbon content, the higher corrosion resistance. In 1Cr13, 2Cr13, 3Cr13 and 4Cr13 four kinds of steel, the corrosion resistance and strength of the order is just the opposite. In addition, carbon has an effect on the mechanical properties of stainless steel matrix.
Q:Is carbon monoxide good for people?
No good, generally will cause poisoning, gas poisoning is actually carbon monoxide poisoning
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:No. 5 carbon battery charging, No. 5 1A battery capacity, capacity of the equivalent?
The carbon battery voltage is 1.5V, and the rechargeable battery is only 1.2V. That depends on the capacity of the rechargeable battery. You mean 1000MA?
Q:Carbon fiber rod 60
3. carbon fiber product form and manufacturing process carbon fiber has four kinds of products: fiber, fabric, prepreg, and chopped fiber. Cloth refers to fabric made from carbon fibers. Prepreg is a product in which carbon fibers are aligned in one direction and impregnated with carbon fibers or fabrics to form sheets. A staple fiber is a short fiber. These products, together with resins, will form carbon fiber reinforced plastics (CFRP) at different ratios. The resin is attached to the fiber and can be made into a pressure vessel and roll, which is wound around a core and then plasticized or hardened. This method is called "winding forming method"". Put the cloth into a model, and then soak it with resin. It can also be the body part of the production card. This is the "method of resin transfer molding (RTM)". The manufacture of aircraft elements is made by heating, pressing and plasticizing preforms in a autoclave. A strand of prepreg is wrapped around a core and heated and plasticized. This is known as the sheet winding method, which can be used to make a golf club, a fishing rod. The short silk is mixed with resin to form a mixture, which can be used to produce mountain machine components and other products after processing. In the past, prepreg was the most widely used form of carbon fiber, fabricated by sheet winding in a reactor. Recently, however, with the development of new industrial applications, filament winding, blending and other methods of prefabrication have been developed more widely. The use of molding such as RTM has enabled manufacturers to make larger products more efficiently. The combination of carbon fiber with the most suitable resin and prefabrication process makes the application of carbon fiber more attractive.
Q:How to identify a laptop shell is carbon fiber
Carbon fiber, as its name suggests, is made from carbon fiber, so there are several characteristics. First, if it is not colored, you can see the obvious fiber. Second is black carbon color. And it's a lot more than ABS.
