Abstract
Superhigh molecular filtering material without toxicity and smell and active carbon powder are mixed fully and the mixture is molded, sintered through a special process and cooled into the new type composite material carrier active carbon stick. The product has high absorption performance and excellent purification effect, so that it may be used for air purification, water purification, adsorption of organic matter and other field needing absorption purification.
Description
The invention belongs to active carbon stick and preparation method thereof, particularly relate to a kind of carrier material and itself have active carbon stick of microcellular structure and preparation method thereof.Be applicable to that air cleaning, water purification, organic matter adsorption cleaning etc. need the occasion of adsorption cleaning.
Prior art is used for the active carbon stick that air cleaning, water purify, the method for organic matter adsorption cleaning all adopts charcoal canister basically or becomes with adhesives.Conventional method has following drawback:
1, charcoal canister: what loaded its inside is the shape granular activated carbon that looses, and the medium that needs to filter sees through these activated carbon granules, and bacterium and stink in the medium are just absorbed by active carbon.But these activated carbon granules are the loose sand shape, and the medium that need to filter can not fully flow through it, so be easy to cause harmful substance in the medium fully not absorbed by active carbon and cause the filter effect reduction.Or need to filter repeatedly repeatedly just can reach standard.
2, the greatest problem of adhesives active carbon stick existence:
(1) the domestic adhesive overwhelming majority of producing of China all has toxicity at present.If the active carbon stick that is made into these adhesives is used for civilian air cleaning or water purification, can cause great injury to human body undoubtedly.
(2) adhesive itself is airtight.Make the gas permeability that the active carbon stick carrier not only can not increase carbon rod with it, but also the ventilative micropore of active carbon will be clung obstruction.So not only increase the resistance of carbon rod greatly, filter efficiency is reduced, and also cause the adsorption effect of active carbon to reduce because the micropore of active carbon is stuck.
Task of the present invention is the shortcoming that overcomes prior art, purpose provides simple, the small investment of a kind of technology, and that product has is nonpoisonous and tasteless, fluid resistance is little, absorption property is high, adsorption rate is fast, the scope of application is wide, the advanced composite material (ACM) carrier active carbon rod of good moldability, easy to use, good purification and preparation method thereof.
Purpose of the present invention can realize like this, active carbon stick as composite material carrier of the present invention is to be blended in the sintering of heating in the mould by 25-50% ultra high molecular weight polyethylene (UHMWPE) powder and high density polyethylene (HDPE) (HDPE) powder as carrier and 50%-75% active carbon powder to constitute by weight, and the part by weight of (UHMWPE) powder of ultra high molecular weight polyethylene in the carrier and high density polyethylene (HDPE) (HDPE) powder is 1 to compare 0.1-0.3.
Above-mentioned ultra high molecular weight polyethylene (UHMWPE) and high density polyethylene (HDPE) (HDPE) powder granularity magnitude range are respectively between 40 orders-150 order; Above-mentioned active carbon powder granularity magnitude range is respectively between 16 orders-120 order.
By the preparation method of above-mentioned active carbon stick as composite material carrier, be to be carrier with nonpoisonous and tasteless supra polymer composite filter material; Earlier will be as the ultra high molecular weight polyethylene (UHMWPE) and the sampling of high density polyethylene (HDPE) (HDPE) powder of carrier material, the granularity magnitude range is between 40 orders-150 order; Use 1 part of ultra high molecular weight polyethylene (UHMWPE) powder to add 10-30% (weight %) high density polyethylene (HDPE) (HDPE) powder then, mix and make the carrier material that accounts for gross weight 25%-50%; The ratio that then 16 orders-120 order active carbon powder is accounted for by weight the 50%-75% of gross weight adds in the carrier material and mixes, be filled in the specific mould, both mold ends adds end cap, with press with the composite material compacting, put into drying box again with 200 ℃ of-300 ℃ of sintering, the time is 30 minutes to 60 minutes, and sintering finishes, mould is taken out cooling, promptly make the active carbon stick as composite material carrier finished product after the demoulding.
Carrier material can bonding strand links up in the sintering process of the present invention, is made into the spatial network that a 3 D stereo intersects, and the activated carbon granule of loose sand shape is fixed in the cyberspace, forms an integral body behind the cooling forming; The characteristics and the requirement of the material that various types of active carbons selections can be filtered are as required determined.
Advantage of the present invention and principle are:
1, the characteristic of supra polymer composite filter material itself is exactly nonpoisonous and tasteless open type micropore filter material, it is to be connected together rather than clung the micropore of active carbon by its particle and activated carbon granule strand as carrier, so having increased gas permeability greatly, that fluid resistance is reduced to is minimum, makes active carbon can fully absorb bacterium and stink in the water; It is little more than one times that test shows that the flow resistance of making the active carbon stick of carrier with the supra polymer composite filter material wants the specific viscosity mixture to make the active carbon stick flow resistance of carrier, this carbon rod not only to the bacterium in the water and stink eliminate totally and also the water yield large user of purification very satisfied.
2, the supra polymer composite filter material is a kind of super inert material, any chemical change and physical change can not take place in it in the temperature range that water adapts to, and can not produce any peculiar smell, so but make the active carbon stick long-term storage of carrier and can not go mouldy with it; Efficient sterilizing deodorant activities carbon rod is cheap, and is easy to use, and through use detecting, active carbon up to more than 98%, is that household drinking water purifies and factory's one of optimal instrument of purifying waste water to the absorptivity of water.
Further specify the present invention below in conjunction with embodiment.
