Active carbon is black powder or bulk, graininess, cellular amorphous carbon, also there is the crystal of arranged regular
Carbon.In active carbon in addition to carbon, also include two class admixtures: one kind is chemically combined element, mainly oxygen and hydrogen, these
Element be due to not completely charing and remain in charcoal, or in activation process, external non-carbon element and activated carbon surface
Chemical bonding；Another kind of admixture is ash content, it is the inorganic part of active carbon；Ash content easily causes secondary dirt in activated carbon
Dye.
The primary raw material of active carbon almost can be all organic materials rich in carbon, such as coal, timber, shell, coconut husk, core
Peach shell, apricot shell, jujube shell etc..These carbonaceous materials are converted under high temperature and certain pressure by pyrolysis in activation furnace
Viability charcoal.In this activation process, huge surface area and complicated pore structure are gradually formed, and so-called adsorption process
It being carried out exactly in these holes and on surface, the size of hole plays the role of selection absorption to adsorbate in active carbon, this
It is the reason that not can enter due to macromolecular in the activated carbon pore size smaller than its hole
For example, from it is stringent theoretically, the interception capacity of suspended matter is mentioned from active carbon possessed by active carbon
The surface area of confession.When flow velocity is low, the filter capacity of unit screens out effect mainly from active carbon, and when flow velocity is fast, filtering
Suction-operated of the ability from activated carbon granule surface, granule surface area provided by active carbon is bigger during the filtration process, right
The adhesive force of suspended matter is stronger in water.
Therefore, a large amount of active carbon is widely used in the industries such as medicine, chemical industry and food and sewage treatment correlation neck
