Q:Classification of organic carbon
The organic matter is composed of recombinant LFOM was completely decomposed residue or, to re synthesis of aromatic substances as the main organic matter (mainly humus), its stable structure is complex, in fact this part of organic matter in soil clay is a combination between, or in the process of the formation of soil aggregates Among the internal organic matter enclosed in aggregates, plays a very important role in maintaining the structure of aggregates, it is difficult to be utilized by microorganisms, soil carbon pool is stable. The content of 2 components of features from a certain extent that the carbon sensitive to climatic and environmental changes of the reaction.
Q:What kinds of barbecue carbon do you have?
Common carbon on the market are: flammable carbon, charcoal, carbon three mechanisms. Flammable carbon available in outdoor stores, there are two kinds of square and pie. The surface of flammable carbon has a flammable layer, which is easier to ignite than ordinary charcoal.
Q:What is the difference in carbon content of low carbon steel, medium carbon steel and high carbon steel?
The carbon content of high carbon steel (AISI1055 ~ 1095) is 0.60% to 1.03%, manganese content is 0.30% to 0.90%, phosphorus content is not more than 0.04%, sulfur content is not more than 0.05%.
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 do you hit carbon 14 with word? Five
Enter 14C, select "14", "point font" or "tool" button "superscript"".
Q:The similarities and differences of five existing forms of cementite in iron carbon alloy are analyzed
A: cementite in iron graphite phase, carbon content more than 4.3%, in L (Fe + Fe3C) two-phase region crystallization of Fe3C as a primary cementite formation temperature in the eutectic temperature (1148 DEG C) above, morphology in large sheets (during eutectic organization). Carbon content from 4.3% to 6.69% is the typical composition range.
Q:How about carbon content of coal ash?
Ash, carbon content, ash, carbon content, ash, carbon content, ash, carbon content, determination, determination, determination, determination (determination, determination)1 sampling(1) in the different positions of the ash, 7-10 points are deep to collect ash and 2-3kg. When sampling, not intentionally pick or avoid channels of ash, namely as ash samples taken, regardless of its size, regardless of the depth of color, regardless of its hardness, as far as possible to obtain a fully representative sample.(2) slag made on thick steel plate clean, which is smashed big gray block, mixing evenly into a cone, flattened, with a shovel cut ten sub center line, which is divided into 4 parts, two samples of diagonal, the other half abandoned.(3) repeat (2) operation. Reduce the amount to several times, until the ash is reduced to about 50 grams. Bring the ash back to the laboratory. The abandoned ash is discharged back into the ash heap.2, sample preparation(1) the ash in the laboratory will be retrieved and dried in a heated air drying oven (about 1 hours) at 105-110 degrees centigrade.(2) crushing the dry ashes with the disc vibrating mill, and the fine ash powder is the analysis sample.
Q:Will long-term use of carbon alloy chopsticks cause cancer?
The chopsticks are washed with water for a long time, and the water content is especially high. The chopsticks are placed in the non ventilated place for a long time, and the chances of deterioration of the chopsticks are improved." Huang Yahui said, especially the moldy chopsticks, may be contaminated by aflatoxin. It is understood that aflatoxin is the 1 class of carcinogens, is a highly toxic highly toxic substances, human and animal liver tissue will have a damaging effect, can lead to serious liver cancer or even death. Huang Yahui warned that the public should be weekly chopsticks into boiling water after half an hour, placed in the air to air dry before use, it can achieve the disinfection effect, and can effectively and conveniently remove mildew in chopsticks. In addition, it is best to use half a year to replace the new chopsticks, so you don't have to worry too much. "The selection of chopsticks is also very exquisite."." Huang Yahui said, "the ideal chopsticks are bamboo chopsticks and non staining wooden chopsticks.". After the dyed or painted wood, paint and stain will enter the body with food. When in use, especially the stain in heavy metals, benzene and other harmful substances, can cause gastrointestinal inflammation, ulceration, erosion, serious can cause cancer.
Q:The organic matter M, which contains only carbon, hydrogen and oxygen, was measured by mass spectrometer.
The mass fraction of oxygen element is 48.48%, the mass fraction of hydrocarbon is =51.52%, and the mass ratio is 15:2. The mass fraction of carbon is =51.52%x15/ (15+2) =45.46%, and the mass fraction of hydrogen is =51.52%x2/ (15+2) =6.06%The atomic number of C, H and O is higher than that of =45.46%/12:6.06%/1:48.48%/16=3.79:6.06:3.03Molecules contain only COOH, and oxygen atoms must be even numbers.Therefore, the number of atoms in C, H and O can be reduced to =5:8:4, which may be C5H8O4, and the relative molecular weight is 132
Q:How do carbon fibers shape?
Carbon fiber is not plastic, and plastic is not the same material. Carbon fiber forming process is mainly:A molding process is: by hand will prepreg paper in the mold, and then curing. This is the biggest advantage of simple manufacturing process, manual to complete more complex operations, can process the complex shape parts, suitable for small batch production; the disadvantage is low efficiency and poor labor conditions, labor intensity is big.Filament winding forming technology: the earliest continuous forming process, that is, the fiber is dipped into the resin through the resin trough, and then wrapped on the rotating core mold according to certain rules. Then, the glue is solidified and formed by heating. A prominent feature is that it is in accordance with the stress situation of products, the fiber according to a certain rule arrangement, so as to give full play to the strength of the fiber, obtain the lightweight products; can realize continuous and mechanized production in the process, and short production cycle, high production efficiency, low labor intensity, suitable for manufacturing cylinder the sphere, and some positive curvature gyration bodies or tubular products.
