Description
Technical field
The present invention is specifically related to a kind of novel negative ion automatically cleaning activated carbon fiber preparation method.
Background technology
ACF nanometer activated carbon fiber is a kind of nano surface particle, has the system that irregular structure is mixed with nano-space.Its fibre diameter is thin, large with the contact area of absorbate, and can even contact and absorption, and sorbing material is fully utilized.Efficiency is high, and has the various very thin statements such as fiber, felt, cloth and paper, and the direct opening of hole is at fiber surface, and it is short that its adsorbate arrives the evolving path of adsorption potential, and the external surface area of itself exceeds two orders of magnitude compared with internal surface area.There is micropore shape structure, pore radius is below 2nm, its pore-size distribution is narrow, special pore shows a monodisperse distribution, form its structure by the fine pore of different size, and mesopore, aperture diffusion present polydispersion type and distribute, and the difference in each pore structure is larger, and its main cause is the difference of raw material.In ACF, without macropore, only have a small amount of transitional pore, micropore is distributed in fiber surface, its rate of adsorption is fast, and macropore effect is played in the space of ACF tow, and gas phase and liquid phase substance are had to good suction-operated, its external surface area is large, and the de-speed of suction is fast, is 10～100 times of particle diameter active carbons.Along with specific area increases, the average pore size of pore increases thereupon, and pore volume increases, and occurs in the rear filling pore of absorption in pore.It is large that its specific area increases adsorption capacity, is 10 times of granular active carbon, adsorbable processing low concentration gas or have highly active material.The bulk density of ACF is little, the larger liquid of little, the adsorbable viscosity of filtration resistance, and kinetic equation loss is little.ACF surface of solids atom is unsaturation, there is unique surface chemistry performance, crystallite in the time that ignition temperature is low easily with the oxide isolation generation oxidation product that reacts, mainly contain the oxy radicals such as carboxyl, phenolic group, quinonyl, and contain the functional groups such as sulfenyl, nitrogen element, halogen.Its surface acidity and adsorption equilibrium have close relationship.According to the criteria for classification of IUPAC (1UPAC), the pore of adsorbent is divided three classes: aperture be greater than 50nm for macropore, 2nm～50nm's be mesopore, 0.8nm～2nm for micropore and what be less than 0.8nm is sub-micro hole.The hole of ACF is mainly the micropore that Turbostratic charcoal and graphite microcrystal form.A large amount of existence of micropore increase the surface area of ACF, also make its adsorbance improve simultaneously.Macropore in adsorbent is that it is controlling adsorption rate as the passage that is adsorbed molecule arrival adsorption potential; Its fibre diameter of ACF generally 10nm～13nm, external surface area is large, micropore is abundant and narrowly distributing, be easy to contact with adsorbate, diffusional resistance is little, so its adsorption desorption speed is fast, is conducive to adsorbing separation.And, can make as required the various forms such as felt, cloth, paper, be adapted to multiple use.ACF is formed by CF activation.CF is polycrystalline random graphits structure, changes into after ACF, and structural motif does not change.ACF is heteropical heterogeneous structure, part of atoms is sloughed to rear formation microcellular structure makes it to generate the oxygen-content active such as carboxyl, carbonyl group due to high-temperature vapor, and the acidity on its surface is increased.Specific area is about 1 200m/g, much larger than CF, while activation, can reach 3000m/g under harsh conditions.ACF is the microcellular structure in the narrow single aperture of distribution, and its hole can produce cohesion capillaceous.Owing to having micropore, its adsorption and desorption speed is much larger than two orders of magnitude, and adsorbance is large.In packed bed, the bed resistance of fluid is little.Can be used as that catalyst and catalyst carrier use is phosphorus, nitrogen, chlorine etc. at the intramolecular trace hetero atom of ACF.In the time of activation, after part hetero atom is divested, the impurity on surface greatly reduces.Due to the effect of oxidizing gas in activation, surperficial oxy radical strengthens, and mainly contains acidic-group, as carboxyl etc.Neutral radical is complete in carbonyl, lactone group etc.Basic group has peroxidating base etc.ACF can, because of the method difference of activation, contain the oxygen base product different with surface acid alkalescence and generate different surfaces.Under the effect of water, its redox ability is stronger.Because can making some radical oxidations, the existence of water becomes hydroxyl.After surperficial oxy radical number increases, surface oxidation reduction capacity increases thus.In recent years, along with the continuous reinforcement of mankind's environmental consciousness, for the environment of existence, the performance requirement that particularly air, water etc. is purified the environment-friendly materials such as closely-related active carbon is more and more higher, and granular or powdered activated carbon can finely meet instructions for use.
Traditional active carbon is a kind of raw material of wood-charcoal of granular or powdery, since 20 beginnings of the century were realized suitability for industrialized production, has separated and has purified waste water and be used widely in the aspect such as deodorizing, purification of other liquid.The structure of granular or powdery, its adsorption rate is slower, and separative efficiency is not high, and particularly its physical aspect has much inconvenience in the time of application, has limited range of application.Little and the narrowly distributing in ACF aperture, adsorption rate is fast, and adsorbance is large, easily regeneration.Compared with powdery (5nm～30nm) active carbon, the micro mist dirt that ACF in use produces is few, can be made into the goods of the variforms such as yarn, line, fabric, felt, more flexible when use.ACF is considered to one of classic environment-friendly materials of 21 century, the application of having succeeded at aspects such as gas and fluid purification, pernicious gas and liquid adsorption processing, solvent recovery, functional electrode materials.
