Calcined Anthracite
Fixed carbon: 90%-95%
S: 0.5% max
Size: 0-3. 3-5.3-15 or as request

 It used the high quality anthracite as raw materials through high temperature calcined at over 2000 by the DC electric calciner with results in eliminating the moisture and volatile matter from anthracite efficiently, improving the density and the electric conductivity and strengthening the mechanical strength and anti-oxidation. It has good characteristics with low ash, low resistvity, low sulphur, high carbon and high density. It is the best material for high quality carbon products.

Advantage and competitive of caclined anthracite:

1. strong supply capability 

2. fast transportation

3. lower and reasonable price for your reference

4.low sulphur, low ash

5.fixed carbon:95% -90%

6..sulphur:lower than 0.3%

Q:Method for making carbon fiber board
Carbon fiber sheet is a carbon fiber heating paper, which is insulated and protected by epoxy resin.
Q:What is electrical carbon?
Different uses have different varieties, according to the use of electric carbon varieties can be divided into:(1) sliding contact carbon brushes and carbon sliders for all kinds of motor brushes.(2) various carbon and graphite contacts used in high power switches, relays, etc..(3) with various carbon arc lighting, carbon arc gouging, spectral analysis and arc furnace.(4) all kinds of high purity graphite electrodes, insulation and supporting elements for electric vacuum devices.(5) various electrodes used in dry cells and electrolytic cells.(6) the resistance effect of carbon. Made of various resistance, post, communication with the microphone carbon sand, resistance heating elements etc..
Q:What is carbon PC?
Polycarbonate (PC), polycarbonate is a molecular chain containing [O-R-O-CO] chain thermoplastic resin according to the molecular structure of the ester can be divided into aliphatic, alicyclic and aromatic type of fat, which has the practical value of the aromatic polycarbonate, and bisphenol A polycarbonate as the most important, molecular weight is usually 3-10 million.Polycarbonate, English Polycarbonate, referred to as PC.PC is a kind of amorphous, odorless, non-toxic, highly transparent colorless or slightly yellow thermoplastic engineering plastics, has excellent physical and mechanical properties, especially excellent shock resistance, tensile strength, bending strength, compressive strength and high creep; small size is stable; good heat resistance and low temperature resistance, mechanical properties, stability in a wide range of temperature dimensional stability, electrical properties and flame retardant properties, can be used for a long time at -60~120 deg.c; no obvious melting point, a molten state at 220-230 DEG C; the molecular chain rigidity, melt viscosity and high water absorption resin; small, small shrinkage, high precision, good dimensional stability, permeability of films is small; self extinguishing materials; stable to light, but not UV resistance, good weather resistance; oil resistance, acid and alkali resistance, no oxygen acid and amine, Ketones are soluble in chlorinated hydrocarbons and aromatic solvents. They are easy to cause hydrolysis and cracking in water for a long time. Because of their poor fatigue resistance, they are prone to stress cracking, poor solvent resistance and poor wear resistance
Q:Is the hardness or softness of the steel with higher carbon content?
With the increase of carbon content, the strength and hardness of steel increase, while the plasticity and toughness decrease. When the carbon content is more than 1%, the strength of steel decreases.
Q:How do you remove the carbon stains on your clothes?
Cleaning instructions for clothing * collar / cuff: Soak clothes in warm water with detergent powder for 15-20 minutes before washing. * Yellow White Sox: soaking washing powder for 30 minutes, then normal washing. * milk stains: use washing powder to do stain pretreatment and normal washing. If the milk stains are stubborn, you may need to use a bleach that is harmless to the clothes. * ordinary oil: a strong detergent is used for pre treatment and normal washing; if desired, bleaching of stubborn stains can also be done with bleach. The clothing removal method of rubber and plastic sex pigment stains with rubber and plastic pigment stains, it is difficult to remove, only use a suitable way to remove. 1, adhesive removal of stains clothes with glue stains, can use acetone or banana on glue water stains, use a brush to repeated washing, until soft glue stains off from the fabric, and then rinse with water. Once, can be repeated scrubbing several times, and finally wash. Do not use this method to avoid fabric damage. 2, white latex stain removal of white latex is a kind of synthetic resin, polyvinyl acetate emulsion. It is characterized by the addition of nylon silk and so on, the vast majority of fiber quality materials have bonding role, it can firmly adhere to the clothing. It has another characteristic that can dissolve in a variety of solutions. We will use its own characteristics to find ways to remove. By 60 DEG C or 8:2 alcohol liquor (95%) and a mixture of water, white glue stains on the clothes soak, soak about half an hour later, you can wash with water scrubbing, until...
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.
Q:Why is carbon content of stainless steel low?
The corrosion resistance of stainless steel decreases with the increase of carbon content. Therefore, the carbon content of most stainless steel is lower, the maximum is not more than 1.2%, and some steel's Omega C (carbon content) is even less than 0.03% (such as 00Cr12). The main alloying element in stainless steel is Cr (chromium), and the steel has corrosion resistance only when the Cr content reaches a certain value. Therefore, stainless steel in general Cr (chromium) content of at least 10.5%. Stainless steel also contains Ni, Ti, Mn, N, Nb, Mo, Si, Cu and other elements.
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: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:Why can carbon fiber in addition to static electricity ah?
Is graphite conductive? Think about it!
