Product Description:


Carbon Additive also called Calcined anthracite Coal, Gas Calcined Anthracite Coal, Carbon Raiser.

The main raw material is Ningxia unique high quality anthracite, with characteristic of low ash and low sulfur. Carbon additive has two main uses, namely as the fuel and additive. When being used as the carbon additive of steel-smelting, and casting, the fixed carbon may achieve above 95%.


It may substitute massively refinery coke or the stone grinds. Meanwhile its cost is much less than the refinery coke and the stone grinds. Carbon Additive may also use as the fuel, for its calorific value may achieve above 9386K/KG. It may substitute burnt carbon massively. The burnt carbon exportation needs the quota; therefore the carburizing agent price superiority is similarly obvious.

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:What is the density of carbon steel and alloy steel?
Manganese steel 7.8115CrA 7.74 steel20Cr, 30Cr, 40Cr steel, 7.8238CrA 7.80 steelChromium vanadium, chromium nickel, chromium nickel molybdenum, chromium, manganese, silicon, manganese, nickel chromium manganese silicon silicon steel 7.85Chromium nickel tungsten steel 7.80
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 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:Process for producing carbon fiber board
Carbon fiber forming process:1, pressing method. This method is put into the carbon fiber prepreg resin has the metal mold, the pressure of excess glue overflow, then high temperature curing, stripping the finished products come out, this method is the most suitable for production of auto parts.2, hand paste layer method. The impregnated carbon fiber sheets are cut or laminated, or so that the sides of the layer are brushed with resin and then pressed to form. This method can be used arbitrarily to select the direction, size and thickness of fibers and is widely used. Note that the shape of the layer is smaller than the shape of the mold, so that the fiber will not bend when it is pressed in the mold.3 、 vacuum bag hot pressing method. Laminated on the mold hill and covered with heat-resistant film, applying pressure from the soft pocket to the laminate and curing in hot pressing.4, winding forming method. The carbon fiber monofilament is wound on the carbon fiber shaft, and is especially suitable for making cylindrical and hollow containers.5, pultrusion. The carbon fiber is fully infiltrated, and the resin and air are removed by extrusion, then solidified in the furnace. The method is simple and suitable for preparing rod shaped and tubular parts.
Q:What are the specifications of carbon fiber cloth?
The units of weight are in units of g per square meter
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:When will amines be fertilized?
Rain does not applyAttention should be paid to the following problems in the application of ammonium bicarbonate:(1) ammonium bicarbonate can not be mixed with alkaline fertilizer in order to prevent ammonia volatilization and cause nitrogen losses.(2) to achieve the "five not": that is not mixed with fine soil without nitrogen, and there was dew without nitrogen, rain without nitrogen, Tian no inch of water without nitrogen, the sun does not apply. If fertilization time was sufficient, it is best able to make deep application of ammonium bicarbonate fertilizer or fertilizer ball. In addition, ammonium bicarbonate in transportation and storage, light light, close packed, stored in a cool dry place, not with the basic fertilizer and human excrement mixed, so as to avoid loss of effective fertilizer.(3) do not contact crops, seeds, roots, stems and leaves, so as not to burn the plants.(4) do not do fertilizer, otherwise it may affect the germination of seeds.(5): bogey and mixed fertilizer after application of ammonium bicarbonate will release ammonia, fertilizer and fertilizer will make contact, bacteria in the death of the fertilizer losing effect.(6) avoid spraying: spraying ammonium bicarbonate are easy to be burnt leaf, affecting crop photosynthesis
Q:What is electrical carbon?
The main component of electrical carbon material is carbon. Because of the different structures, carbon has two types: crystalline carbon and amorphous carbon. Crystalline carbon is mainly composed of graphite, amorphous carbon, mainly coke, charcoal, carbon black and so on. Coal used daily is an impure amorphous carbon.Graphite has a crystalline structure of six square system. It has numerous parallel layers superimposed on each layer of carbon atoms at the top angles of the six angles plane, forming an ordered arrangement of three-dimensional space. Because the distance between the layers of the graphite crystal is much larger than the distance between the carbon atoms on the surface, the graphite has an obvious anisotropy. When there is external force, the surface of graphite is easy to slip, so it shows self lubrication characteristics. In high purity graphite crystals, the valence band overlaps the conduction band, so the high conductivity of the metalloid is demonstratedThe arrangement of carbon atoms in amorphous carbon is haphazard, and it is easier to slip than the graphite layer, and its hardness is 4~5 times higher than that of graphite. Amorphous carbon, if treated at 2 200~2 5000C high temperature, can transform the disordered structure into an ordered arrangement of two-dimensional space.
Q:What are the 3K, 12K, UD, etc. in the appearance requirements of the carbon fiber bicycle? What's the difference?
3K has 220 grams and 240 grams a square meter, we do carbon fiber automotive supplies, that is, the higher the number of 3K K, the width of each bundle of carbon fiber filaments, each bundle has hundreds of silk composition
