Activated carbon fiber properties
Activated carbon fiber, also known as fibrous activated carbon, a new generation of highly efficient and eco-friendly active adsorption material material is activated carbon replacement products. High-tech and high value-added products is the main feature, allows adsorption device miniaturization , thin layer adsorption layer adsorption leakage, high efficiency, energy saving and economical, you can complete the work of granular activated carbon can not be achieved, any other type of activated carbon fiber can not be compared, active adsorption material and environmental engineering materials outstanding performance.
Activated carbon fiber (ACF) is made of natural fibers or synthetic fibers through carbonization made of organic chemistry. The main ingredients composed of carbon atoms. In a similar graphite carbon atoms main microchip, milk layer stack form.
ACF another notable structure is the ratio of the surface area of a well-developed, rich pore size. Usually activated carbon fiber (ACF) of the specific surface area of up to 1000-1600m2 / g, pore volume of about 90%, of its pore size of 10A -40A.
1, the adsorption capacity: organic gases stench, foul substance (NO; NO2; SO2; H2S; NH3; CO; CO2) and powdered activated carbon adsorption particles than large 20-30 times.
Aqueous solution of inorganic substances, fuels, organic matter and heavy metal ion adsorption ratio particles, powdered activated carbon 5-6 times higher.
Micro-organisms and bacteria have excellent adsorption capacity. (Eg, E. coli adsorption rate of up to 94% -99%).
Low concentration of adsorbate adsorption capacity is particularly good as the adsorption of PPM remains high adsorption capacity, while GAC adsorption materials are often greatly reduced adsorption capacity at low concentrations.
2, absorption speed: Absorption of gases generally tens of seconds to several minutes to reach adsorption equilibrium, GAC higher than 2-3 orders of magnitude.
3; desorption speed; easy regeneration: with 120 ℃ -150 ℃ hot air heating 10-30 minutes to complete in a number of adsorption and desorption process, the remains of the original adsorption properties.
4, good temperature resistance: high temperature above 1000 ℃ in an inert gas, fire in air point of 500 ℃.
5, acid, alkali, has good electrical properties and chemical stability.
6, less ash: its ash content is only one tenth of the GAC, small catalytic materials for recycling
