Description
Technical field
The present invention relates to a kind of functional activity carbon fibers, preparation method and applications.
Background technique
Activated carbon fiber (activated carbon fiber, ACF), also referred to as fibrous activated carbon, is a kind of performance
It is more with micropore, compare table better than the high-efficiency activated adsorbent material and environment-friendly engineering material of powder activated carbon and grain active carbon
The big design feature of area, the carbon atom that it has more than 50% are located at surfaces externally and internally and have been built into unique adsorption structure, lead to
It is commonly referred to as superficiality solid.Activated carbon fiber is using polypropylene-base, viscous glue based fibre, pitch-based fiber as raw material, through high temperature
Carbonization-activation process and manufactured novel adsorbent material, relatively narrow pore-size distribution and more developed specific surface area make it
With faster adsorption and desorption speed and biggish adsorption capacity, and since it is convenient to be processed as cloth, felt, paper etc. no
Same shape, there is the characteristics such as corrosion-resistant acid and alkali-resistance, so that one, which comes out, has just obtained the extensive concern and in-depth study of society,
Carbon fiber is widely used in many fields at present, such as environmental protection, catalysis, medicine, military project.
With the continuous improvement of current environmental pollution to become increasingly conspicuous with human environment consciousness, curing "three waste" pollution and protection
Living environment oneself through being included in the agenda of respective government agencies.Activated carbon fiber can efficiently remove having in gas or solution
Evil substance is to be widely used in drinking the purification of water and air, the recycling of solvent, the processing of waste water, the manufacture of catalyst and a
The hitech materials in the hard-core technologies fields such as body protection.Carbon fiber has obtained widely in solvent recovery and water process in recent years
Using being described as in 21st century one of environment-friendly materials the most advanced by people due to its vast development prospect.
As the porous charcoal adsorbent material of the first generation, active carbon because from a wealth of sources, it is moderate the features such as, become the most frequently used
Adsorbent material, but due to normal activated carbon there are ash content height, Kong Rong little, the wide, specific surface area of micropore distribution be small and absorption
The features such as selecting performance poor, in addition some limitations of its surface functional group and electrochemical properties, go it to the absorption of pollutant
Granular and powdered activated carbon limited except acting on and original obviously exposes many and is difficult to the weakness overcome, and its physics
Shape makes it is more inconvenient on application operating, engineering adaptability is poor etc., and with production and improvement of living standard, people couple
The performance requirement of the adsorbent materials such as active carbon is also higher and higher, therefore active carbon is far from satisfying the requirement of domestic and international market.
Activated carbon fiber is the novel carbon material adsorbing material of the second generation, is a kind of porous fiber shape adsorbent material, structure
Upper and active carbon has very big difference.Activated carbon fiber has fibre diameter small, and specific surface area is high, and microcellular structure is flourishing, aperture
Small and narrowly distributing, adsorption capacity is big, and adsorption/desorption speed is fast, and regeneration is easier to, and can be prepared into according to specific requirement accordingly
Form, such as felt, cloth, it is easy to use the advantages that.The matrix material of manufacture activated carbon fiber has very much, such as polyacrylonitrile, poly- second
Enol, viscose rayon, phenolic fiber and pitch-based fiber etc..These raw materials are made by pre-oxidation, charing and activation
Activated carbon fiber.Especially polyacrylonitrile based activated carbon fiber has chalcogenide compound and compound nitrogen series containing nitrogen functional group
There is special adsorption capacity, use scope is wider.However being widely used for activated carbon fiber is also subject to certain restrictions, it is main because
Element is cost and fibre property, limits its extensive use.The surface of activated carbon fiber in the prior art can be still not high, also
It requires further improvement；Meanwhile the disadvantages of activated carbon fiber intensity is low, and impact resistance is poor, and anti-microbial property is bad.
