Product Description:



Pitch Coke/Coal Tar Pitch is a kind of black brittleness and blocky piece, lustrously at normal temperature. It has special odour and poisonous and can be easily flame when melting, second-grade inflammable solid.

 Pitch Coke/Coal Tar Pitch is obtained from powerfully processed coal tar. Compared to petroleum asphalt, the adhesiveness is better. Coal Tar Pitch is high quality tar production with high fixed carbon. It has excellent adhesion, waterproofing and resistance against seawater, oil and various chemicals. In these properties, it is much better than petroleum asphalt tar. 

It can be used to produce painting, electrode, pitch coke, and tar felt. It also can be used as fuel and the raw material of asphalt carbon black.



The morphology, chemistry and crystallinity of recarburisers  have a major impact on the overall casting cost. The combined application and cost benefits, which are derived through the use of Desulco, enable foundries to manufacture castings in a highly cost effective manner.

Q:Material characteristics of carbon fiber
Carbon fiber is a kind of new material with excellent mechanical properties due to its two characteristics: carbon material, high tensile strength and soft fiber workability. The tensile strength of carbon fiber is about 2 to 7GPa, and the tensile modulus is about 200 to 700GPa. The density is about 1.5 to 2 grams per cubic centimeter, which is mainly determined by the temperature of the carbonization process except for the structure of the precursor. Generally treated by high temperature 3000 degrees graphitization, the density can reach 2 grams per cubic mile. Coupled with its weight is very light, it is lighter than aluminum, less than 1/4 of steel, than the strength of iron is 20 times. The coefficient of thermal expansion of carbon fiber is different from that of other fibers, and it has anisotropic characteristics. The specific heat capacity of carbon fiber is generally 7.12. The thermal conductivity decreases with increasing temperature and is negative (0.72 to 0.90) parallel to the fiber direction, while the direction perpendicular to the fiber is positive (32 to 22). The specific resistance of carbon fibers is related to the type of fiber. At 25 degrees centigrade, the high modulus is 775, and the high strength carbon fiber is 1500 per centimeter.
Q:What are the carbon monoxide collection methods?
The catchment gas collection, because it is difficult to dissolve in waterOr the airbag
Q:How many points can Yongan change for 1 carbon coins?
Every Thursday at 19:00, carbon points change for carbon coins, 19:30 carbon coins exchange gifts
Q:Carbon injection molding machine heating several degrees
Polycarbonate (PC) is a colorless and transparent engineering plastics, the impact strength is high, the use of a wide temperature range, good creep resistance, electrical insulation and dimensional stability; the disadvantage is sensitive to the gap, environmental stress cracking resistance, with metal insert molding products is difficult.Polycarbonate, English name 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 stability; has good heat resistance and low temperature resistance and with mechanical properties, stable 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, molten at 220-230 DEG C; because the molecular chain rigidity, resin melt viscosity; low water absorption, low shrinkage, size 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, non oxidizing acids and amines, ketones, solution Chlorinated hydrocarbons and aromatic solvents are prone to hydrolysis and cracking in water for a long time. The disadvantage is that they are prone to stress cracking due to poor fatigue resistance, poor solvent resistance and poor wear resistance.
Q:What is the difference between carbon and carbon materials?
Carbon refers to elements. Carbon materials usually refer to materials that contain carbon and are the main bodyCarbon is a carbon containing substance of no composition and property consisting of carbon elementsCarbon materials are usually specified, especially carbon and graphite materialsCarbon material is a broad carbon containing materialAbove.
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:Are carbon fiber materials really expensive?
See where, in a car for example transformation kit, with super run even if the civil area shape roughly the same but the price difference, if you feel that things are expensive, natural carbon prices go up, in fact carbon species layout production process characteristics of professional strength lot, do not understand
Q:Is badminton material good with carbon fiber or carbon fiber + resin? Five
All carbon fiber is good. The resin is only used for the badminton line, not for the racket.All carbon fiber material, is the most important material for badminton racket, all carbon fiber, good toughness, but also take into account the light performance.Carbon composite fiber, that is, in the carbon fiber added ordinary metal elements, such as aluminum, this material is relatively heavy, and toughness is not all carbon material.The best one is the carbon fiber material of racket frame which added to the rare metal, adding rare metal frame strong resilience, stability is better, and more suitable for double play.
Q:Does alumina react with carbon?
NotThe smelting of Al in industry can only be done by electrolysis. Even at high temperatures, the reducibility of C is not as strong as Al, and the melting point of Al2O3 is very high. At this temperature, C has been gasified
Q:60T carbon fiber is equivalent to T hundreds of carbon fibers
Two, 46T, 60T refers to high modulus carbon fibers. M series; T1000 refers to the high strength carbon fiber, belonging to the T series; M series and T series belong to different performance products.
