Q:Why does carbon fiber produce far infrared rays when it is heated?
They are the transition of vibrational levels or rotational levels under conditions of carbon energization. All molecules are doing irregular movements, for example, there is a bond between two molecules, equivalent to a spring connecting two balls connected to two balls, they vibrate, the frequency is v.
Q:How about carbon content of coal ash?
3, burning(1) prepared burning specimen with constant weight in the outer side of the crucible crucible, only a few 10-18ml and drying on the only black ink written into the code, mother Eph furnace, baby 50+-25 degrees Celsius temperature burning 1 hours after cooling, weighing with analytical balance, write down the number of crucible weight again after burning, and then weighed to weight two times constant (weight <=0.0004 grams). Record crucible weight G1.(2) place about 1 grams of dry ash sample in a constant crucible, and accurately weigh (accurate to 0.0001 grams), record (crucible + sample) weight G2. (3) a crucible with soil sample is placed in a crucible cover, heated to 875 degrees Celsius in the Maffei furnace for ignition, keep the temperature of 850+-25 degrees Celsius, after 2 hours, take out, after cooling, cooling to room temperature to put in a drying box. 4 W T'o X7 I3 L) |% "Z (4) weighing burned (crucible + specimen), down under the weight of G3.4. Calculate ash carbon content C (%) = (G2-G3) / (G2-G1) *100 (%)
Q:What are the carbon nanotube applications?
The hydrogen storage materials: gas adsorption in adsorption is a solid adsorbent surface behavior the occurrence process of adsorbent and solid surface characteristics are closely related. The adsorption mechanism of nanoparticles, it was generally accepted that adsorption of carbon nanotubes is mainly due to the surface hydroxyl carbon nanotubes nanoparticles. The effect of carbon nanotubes on the surface of to hydroxyl and certain cationic bonding, so as to achieve the apparent of metal ions or organic matter adsorption. In addition, carbon nanotube particles have a large surface area, is also an important reason for the adsorption of carbon nanotubes. Zheng Qingrong, Gu Anzhong and [4] were studied on the adsorption behavior of hydrogen in carbon nanotubes Cheng Hui Ming et al. Synthesis of SWNTS treated properly can store hydrogen at room temperature, the hydrogen storage weight of up to 4.2%, and 78.3% of the hydrogen storage under normal temperature and pressure The hydrogen is released, and the remaining hydrogen is released after heating. The SWNTS can be reused and has a high commercial valueThe proton exchange membrane fuel cell (PEM) is a new type of carbon nanotubes: fuel cell vehicle power supply the most potential, the fuel cell through the consumption of hydrogen to generate electricity, the exhaust gas discharged into water vapor, therefore no pollution. It is compared with the lithium ion battery and Ni MH battery has great superiority. Can use carbon nanotubes hydrogen storage material supply hydrogen, can also be through the decomposition of oil and gas and other hydrocarbons or directly from the air to obtain hydrogen fuel cell hydrogen source.
Q:Is aluminum alloy expensive or high carbon steel expensive?
Aluminum must be expensive, carbon steel is rubbish
Q:What is the difference between soil organic matter and soil organic carbon?
Organic matter is organic matter, but a large part of which is composed of carbon, but carbon content of different organic matter is different, the conversion coefficient is 1.724, most of the organic matter and organic carbon conversion of a mean value is the value.
Q:Why carbon 14 can be used to measure the age of matter?
How to use the half-life of C-14 measurement of a substance to the age due to its half-life of 5730 years, and the carbon is one of the organic elements in biological survival time, the need to breathe, in which 14 carbon content is fairly constant, creatures die will stop breathing, the body began to reduce carbon 14 people through. Lean a antique 14 carbon content, to estimate the approximate age, this process is known as carbon dating. The study found that cosmic rays from space continuous bombardment of atmosphere, this will make the bombardment of carbon atoms in the atmosphere to form part of the ordinary radioactive carbon atoms.
Q:Where do I buy high-grade rock coal in underground city?
Mall. In fact, BUG can be card out! Inside the palace there is that BUG, but I personally think that no use, I used to strengthen the use of advanced carbon weapons on 12, even 3 did not become a storm, this is only the way to make money TX it
Q:Why carbon fiber resistant to low temperature
Resistance to 180 DEG C carbon fiber can be low temperature, under this condition, many materials are brittle, even sturdy steel has become fragile than glass, and carbon fiber under this condition is still very soft.
Q:Which brand is good for carbon fiber board?
You are not for the prestressing bar, if you find the building reinforcement for Tianjin Beijing card, if you do the structure reinforcement for Jiangsu and Wuxi via the new material industry, these are relatively well-known.
Q:Why can carbon fiber in addition to static electricity ah?
The elimination of electricity is based on the leakage of charge. The carbon fiber has a weak corona discharge, so it combines the charge.
