Product Description:

1.Structure of Calcined Petroleum Coke Description

Calcined Petroleum Coke is made from raw petroleum coke,which is calcined in furnace at a high temperature(1200-1300℃).CPC/Calcined Petroleum Coke is widely used in steelmaking,castings manufacture and other metallurgical industry as a kind of recarburizer because of its high fixed carbon content,low sulfur content and high absorb rate.Besides,it is also a best kind of raw materials for producing artifical graphite(GPC/Graphitized Petroleum Coke) under the graphitizing temperature(2800℃).

2.Main Features of the Calcined Petroleum Coke

High-purity graphitized petroleum coke is made from high quality petroleum coke under a temperature of 2,500-3,500°C. As a high-purity carbon material, it has characteristics of high fixed carbon content, low sulfur, low ash, low porosity etc.It can be used as carbon raiser (Recarburizer) to produce high quality steel,cast iron and alloy.It can also be used in plastic and rubber as an additive.

Q:Why are carbon fibers divided into high strength and high modulus?
1, carbon fiber has a benzene ring structure, making it difficult to rotate the molecular chain. A polymer molecule cannot fold and stretch to form a rodlike structure, thus giving fibers a high modulus.The linear structure of carbon fiber polymers allows molecules to be arranged so closely that a large number of polymer molecules can be accommodated in a unit volume. This high density makes the fibers stronger.
Q:What are carbon skateboards?
When the skateboard wear to the limit, only in the maintenance of the daily locomotive can be replaced, so that although it is more troublesome, but it is always better than the replacement of contact wire.
Q:Can carbon in barbecue cause cancer? Can carbonated food cause cancer?
It will be。WHO published 3 years of research results, said barbecue foods produce carcinogenic substances are toxic, "eat barbecue, equivalent to smoking."". A US research center report even said eating a roast chicken leg is equivalent to the toxicity of 60 cigarettes; women who eat barbecue are 2 times more likely to develop breast cancer than other women.
Q:What is carbon emission and what harm does it do? How can carbon dioxide be prevented?
They also believe that the mechanism of independent coking causes and synthesis gas generation, through the use of appropriate catalyst can avoid from kinetics of coke.It is found that the effect of catalyst by coke gas ratio of material. In 750 degrees, when n (CH4): n (O2) = 2, the catalyst produces a large amount of coke; when n (CH4): n (O2) = 1.75, the catalyst activity is low, but no coke formation; when n (CH4) n (O2) =1.78, the coke on the catalyst surface to achieve single steady-state distribution, almost no decrease of catalyst activity; continuously for 50 hours at 800 DEG C, and the catalyst is very stable.Prevention: 1., the temperature should not be too high, 2. water carbon ratio to a reasonable 3, to ensure the quality of the catalyst
Q:How do you use carbon fourteen to measure the age?
One is obvious a small amount of sample, only 1 ~ 5 mg samples can be, such as a piece of fabric, bone chips, toner trace of ancient ceramics in the surface or pores can be measured; while the conventional carbon - 14 dating rules 1 to 5 grams of samples differ by 3 orders of magnitude. The two is high sensitivity. The sensitivity of 10-15 to 10-16 isotope ratio measurement; while the conventional carbon - 14 dating rules with a difference of 5 to 7 orders of magnitude. Three is a short measurement time, measurement of modern carbon to reach 1% accuracy, only 10 to 20 minutes; while the conventional carbon - 14 dating is 12 ~ 20 hours. It is due to carbon - 14 accelerator mass spectrometry dating method has the advantage, since its inception, has been paid attention to by archaeologists, paleontologists and geologists, and is widely used. It can be said that within 50000 years of cultural relics on the determination of samples, carbon - 14 accelerator mass spectrometry dating method is determined the accuracy of a maximum of 1. carbon. 14 is a radioactive isotope of carbon, was found in 1940. It is produced by cosmic rays collide with a nitrogen atom in the air, which has a half-life of about 5730 years, as the decay of beta decay, 14 atoms into carbon nitrogen atoms.
Q:Benefits of reducing carbon emissions
1, carbon dioxide in fresh air content of about 0.03%. People living in this space will not be harmed, if the indoor gathered a lot of people, and the air is not circulating. Or indoor gas, liquefied petroleum gas and coal combustion, the oxygen content in the air is relatively reduced, produce large amounts of carbon dioxide, the indoor personnel will appear different degrees of poisoning symptoms. As for the maximum allowable content of carbon dioxide in indoor air, there is no uniform regulation in different countries. Japan has a standard of ventilation when the content of carbon dioxide in the indoor air is 0.15%. The following table shows the effect of CO2 content in air on human body.
Q:Why is the solubility of carbon in austenite larger than that in ferrite?
Its properties are similar to that of pure iron, and its plasticity and toughness are good, and its strength and hardness are low. It is usually massive or flaky in steel.The austenite structure is a face centered cubic lattice with a gap radius (0.414~0.225). Because of the larger size of the lattice gap, the solubility of carbon in gamma -Fe is relatively large. It has good plasticity.
Q:What are the specifications of carbon fiber cloth?
Carbon fiber and carbon fiber cloth, carbon fiber cloth, carbon fiber woven cloth, carbon fiber prepreg, carbon fiber cloth, carbon cloth, carbon fiber fabric, carbon fiber, carbon fiber sheet (prepreg) etc.. Carbon fiber reinforced fabric is one kind of unidirectional carbon fiber reinforced product, usually made of 12K carbon fiber silk fabric.Available in two thicknesses: 0.111mm (200g) and 0.167mm (300g). Multiple widths: special widths required for 100mm, 150mm, 200mm, 300mm, 500mm, and other projects. With the continuous development of carbon fiber cloth industry, more and more industries and enterprises have applied to carbon fiber cloth, and some departments have entered the carbon fiber cloth industry and developed.To reinforce the structure of the tensile and shear strength and seismic carbon fiber cloth, the supporting material and impregnated together using a carbon fiber composite material, carbon fiber cloth sheet excellent performance can be enhanced to form a complete system, suitable for processing the building load increasing, the engineering function change, material aging, concrete strength grade is lower than reinforcement design, structure crack treatment, environment protection and repair service component.
Q:Which is better, 13 and 14 carbon breath tests?
According to your case, carbon 14 is cheaper than 13, and the accuracy is the same
Q:What does "carbon free" printing mean when carbon free printing is done?
[1] carbon free copy of a few, several refers to a few colors, that is, a few single! Is that a joint edge is what two of what is triple what you said and so on the boundless contact I estimate that he designer or boss tell you to explain things without Bian Lian refers to not say a contact department or (what) no Bian Lian case is a version of the paper change down on it, but the color edge contact is not the same a version of a few joint Bian Lian have changed several times.
