Activated carbon is an amorphous carbon which is black powder，granular, massive or honeycomb, it also has a regular array carbon crystal. Except the carbon, the activated carbon also contains two kinds of admixtures: one is the combination of chemical elements, mainly hydrogen and oxygen, these elements are due to incomplete carbonization and the residue in the carbon, or in the process of activation, non carbon and activated carbon surface chemical foreign combination, such as when it is activated by the water vapor , the surface of the active carbon is oxidized or water vapor oxidation; another kind of admixture is ash, it is the inorganic part of the carbon ; the ash in the activated carbon is easy to cause…
Carbon brick Is mainly used for refractory brick of blast furnace hearth, carbon brick lining life determines a life. 1950s - the former Soviet Union into China, until the end of the 80s, there is little research on blast furnace carbon brick, has been used in the former Soviet Union led China's ordinary brick masonry, short service life of blast furnace. In late 80s, the development of iron making technology quickly, blast furnace smelting intensity is greatly improved, the original ordinary brick has not met the needs of blast furnace smelting, blast furnace hearth life decreased to 4 in 5 years. At the same time and effect of BF Blast furnace carbon brick in foreign countries, China began to develop…
According to the carbon fiber material , carbon fiber cloth can be divided into: PAN based carbon fiber cloth, rayon based carbon fiber cloth and pitch based carbon fiber cloth, wherein PAN based carbon fiber cloth accounted for more than 90% of the market, so we talk about PAN based carbon fiber cloth mainly. In accordance with the specifications of carbon fiber cloth, it can be divided into: 1K carbon fiber cloth, 3K carbon fiber cloth, 6K carbon fiber cloth, 12K carbon fiber cloth, 24K and above large tow carbon fiber cloth, the number of single carbon fiber tow, 1K=1000 (root), 3K=3000 (root), 6K=6000 (root), 12K=12000 (root). Carbon fiber cloth according to the woven pattern, it can be divided into:…
