Product Description:

Introduction:

The nature graphite mining is lacated in North Korea, we import the raw mining material and product the cargo in China. We gurantee the good quality and the cargo is exported in Korea and to Japan widely.

We produce the natural amorphous graphite powder of amorphous graphit ore material of lutang, in chenhzhou of china, where there is the biggest and best amorphous graphite deposit all over the world.
The natural amorphous graphite powder is widely used in foundry, coating ,battery, electricity conductive material and so on. 


Usage:

(1)Mainly used in pencil making, graphite emulsion for welding rod burden of graphite axle, raw material of battery carbon rod.

(2)Mainly used in Coating in casting refractory material, dye electrode compound, etc.

(3) Mainly used as carbon additive in steel plant, to adjust the content of C in steel.

Q:Can carbon 14 identify the age of porcelain?
Identification of porcelain by carbon 14 is not very accurate.The so-called carbon fourteen assay, radiocarbon dating, uses the carbon fourteen, which is widely found in nature, to measure the age of animals and plants. In prehistoric and ancient, the smaller the impact of human activities on the earth's environment, and carbon in nature fourteen proportions remain constant, animals and plants in the survival time, due to its in vivo The new supersedes the old. sake, carbon fourteen also remained constant; however, the once dead, in fourteen carbon will continue to decay, the half-life is 5730 years, in the sealed state and the outside world is obviously different, which is the principle of carbon fourteen dating. We must note that animals and plants belong to the organic matter. However, most cultural relics, such as porcelain, pottery and bronze, are inorganic. Therefore, the application of carbon fourteen dating in archaeology is very limited.
Q:Does iron have more carbon or more steel?
Iron has a high carbon contentThe main difference is that the pig iron, wrought iron and steel carbon content, carbon content of more than 2% of iron is iron; carbon content of less than 0.04% of the iron, the carbon content in the name of wrought iron; 0.05~2% iron, known as steel.
Q:Why does carbon fiber produce far infrared rays when it is heated?
Far infrared is produced by vibrational energy level transitions, and its wave number is 400-5000/cm., so carbon and silicon rods are often used as infrared light sources in Analytical Chemistry
Q:Is carbon monoxide good for people?
No good, generally will cause poisoning, gas poisoning is actually carbon monoxide poisoning
Q:The dangers of grilled BBQ on humansWhat are the dangers of a charcoal barbecue?
Many people may be skeptical - burnt food really carcinogenic? The American Cancer Society will actively publicly called for "eat barbecue foods, because according to the result of medical research, a piece of a pound (about three steaks) barbecue steak, enough to produce carcinogenic substances the equivalent of six hundred cigarettes, which is one reason why many people do not smoke get lung cancer.According to animal experiment confirms that burnt food can lead to animal cancer.
Q:Is there a line cutting of carbon fibers?
Your question is not clear. Do carbon fibers need to be cut with wire? Are carbon fiber composites? What type? In general, carbon fiber reinforced composites can not be cut by wire. They can be cut by ultrasonic and water cut
Q:Who can explain that bare feet on fire carbon don't burn feet?
The fire is red carbon, but no signs of fire and water after scald. Actually, that's a very simple physical phenomenon. The most mysterious matter where we can buy, can make the carbon fire red instantly cool, people ran fast, naturally not hurt hair.These two substances, one is white borax, and the other is red cinnabar (also known as cinnabar). It turns out that the crystals are dissolved because they absorb large amounts of heat. When borax or cinnabar scattered on the surface of carbon fire, because the heat will make the wood surface temperature drop.
Q:What is the composition of carbon in stainless steel?
(7) chromium can improve the hardenability and wear resistance of steel, and can improve the corrosion resistance and oxidation resistance of steel(8) vanadium; can refine the grain size of steel, improve the steel strength, toughness and wear resistance. When it is in the high temperature melt into austenite, can increase the hardenability of steel; on the contrary, when it is in the form of carbide exists, it will reduce the hardenability.(9) molybdenum can obviously improve hardenability and heat resistance of steel, prevent temper brittleness, and increase residual magnetism and attractive force(10) titanium can refine the grain structure of steel so as to improve the strength and toughness of steel. In stainless steel, titanium can eliminate or mitigate intergranular corrosion of steel(11) nickel can improve the strength and toughness of steel, and improve the hardenability. When the content is high, it can significantly change some physical properties of steel and alloy, and improve the corrosion resistance of steel(12) boron; when the steel contains a trace of (0.001 - 0.005%) boron, the hardenability of steel can be doubled and raised(13) aluminum can refine the grain structure of steel, restrain the aging of low carbon steel, improve the toughness of steel at low temperature, and can also improve the oxidation resistance of steel, improve the wear resistance and fatigue strength of steel(14) copper; its outstanding function is to improve the atmospheric corrosion resistance of ordinary low alloy steel, especially when used in combination with phosphorus
Q:How do you get DNF advanced furnace rock carbon?
Pro, tell you an unfortunate news, out of the eighty furnace rock carbon, old horse recycling, burning their own boilers, and now we strengthen the use of colorless small crystal block, that is, the colorless small crystal block instead of the original furnace rock carbon.
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.
