Description
Technical field
The utility model relates to active carbon nonwoven fabric.
Technical background
The cloth with active carbon of general industry production, be that the method that activated carbon powder and fiber utilization is synthetic is made active carbon cloth, its technological process of production complexity, the product cost is too high, and can weaken and produce gauffer via the reactivity of washing back cloth cover charcoal, just belong to this kind as application number 01137385.7 Chinese invention patent, it discloses " active carbon fiber felt; the continuous preparation method of cloth ", by fibrillation at the uniform velocity by dry behind the preprocessor that 2% ammonium phosphate solution is housed, carbonization under 300~450 ℃ of conditions then, activation and obtaining under 850~1300 ℃ and nitrogen and steam mist condition at last; Make in active carbon dusting mode in addition, cloth cover is given forming the glue surface layer after the gluing earlier, on the glue surface layer, sprinkle activated carbon powder and form active carbon layer, the processing cloth cover of on active carbon layer, fitting.Its integral fabric adsorptivity difference and resistance to water are not good, and the reactivity of the cloth of above-mentioned active carbon cloth cover charcoal after washing can weaken and to produce the gauffer problem still unresolved.There is active carbon to mix again and processes through immersion way, make activated carbon powder attach to nonwoven fabric, form product through the processing oven dry again with nonwoven fabric with glue.It is not only inhomogeneous but also not firm that this product activated carbon powder attaches to nonwoven fabric, do not produce matured product at present as yet, only is applied to the part filtering material.Nonwoven fabric has heat resistance, dissolubility resistent and good water permeability, and has certain water absorbing capacity, is cloth or weaves cotton cloth incomparable.03231443.4 1 kinds of application numbers are health-care compound cloth treated to comprise that composite bed is formed by directly mixing by activated carbon particles and adhesive as the nonwoven fabric of base material and the compound composite bed that contains activated carbon particles on it.Composite bed can be compounded on the nonwoven fabric as base material by simple heating.And thisly leave the making that adhesive promptly can't be finished product, and, must reduce the adsorption capacity and the absorption bacteriostasis of product for a large amount of uses of adhesive, be unfavorable for the environmental protection of product and simplify effect, and the burn-in effects service life of adhesive.Folder charcoal nonwoven fabric is to make through special process is compound putting the high-quality granular activated carbon in the middle of the two-layer nonwoven, has the carbon content height, the adsorption cleaning excellent performance; though the dry linting phenomenon can not take place, the technology simple coarse, thickness is big; only be fit to make various active carbon filters, the scope of application is limited.
Summary of the invention
Technical problem to be solved in the utility model is to provide at prior art that the absorption bacteriostasis is strong, the thin thickness good permeability, be easy to the effective active carbon nonwoven fabric of thermal synthesis type, environmental protection and simplification, it has very strong adsorption capacity to the organic polymer material, and the micro constitutent pigment in the liquid, odorous substance etc. are had height removal ability, be convenient to make different activities charcoal product.
The utility model solves the problems of the technologies described above the technical scheme that is adopted: active carbon nonwoven fabric, comprise nonwoven layer, concrete technical measures also comprise: nonwoven layer by in the layer to aspect also evenly absorption melt and have the active carbon layer that constitutes by the floury structure particle, active carbon layer infiltrates part in the nonwoven layer matrix and constitutes active carbon and merge and tie.
The measure of taking for the optimization such scheme specifically comprises:
For adapting to different use occasions and environment, activated carbon powder powder structure particles distribution proportion in nonwoven layer is 1%~100% in the active carbon that can the produce fusion knot.
For obtaining better products, active carbon content accounts for 5%~60% of corresponding nonwoven fabric and active carbon total amount in the active carbon fusion knot; Floury structure particle diameter in the active carbon layer is 20~420 orders, and shared percentage by weight is that methylene blue accounts for 1.2%, and moisture content accounts for 10%, and ash accounts for 5%, and iron content accounts for 0.01%, and pH value is 7~9; The nonwoven fabric aspect quantitatively be 8~120 the gram/square metre, longitudinal fracture intensity is 2~120N/5cm, thickness is 0.1~10mm.
Further prioritization scheme, the product of the effect that obtains has nonwoven layer and even absorption is melted on the active carbon aspect.
Prioritization scheme further, the product of the effect that obtains, nonwoven layer through even absorption melt have the compound nonwoven cloth layer more evenly absorption melt the knot active carbon layer, and active carbon layer infiltrates part in the compound nonwoven cloth layer matrix down and also constitutes active carbon and merge knot; The active carbon aspect again through even absorption melt have the compound nonwoven cloth layer again more evenly absorption melt and have nonwoven layer.
Above-mentioned nonwoven layer is expected for being pulverized by wood pulp, the composite fibre material list solely or in proportion mixes after fiber evenly becomes net arrangement evenly to go up net forming, imposes the pulp air-lay process non-weaving cloth that adhesive is made at surface selectivity; The compound nonwoven cloth layer is for evenly to become net arrangement evenly to go up the mixing pulp air-laid nonwoven fabric of net forming by mixture through fiber; This mixture is pulverized material, composite fibre material list by wood pulp and solely or is in proportion mixed, and mixes composition mutually with activated carbon powder powder structure particles in proportion again.
Compared with prior art, the utility model by nonwoven layer by in the layer to aspect evenly absorption melt and have the active carbon layer that constitutes by the floury structure particle, active carbon layer infiltrates part in the nonwoven layer matrix and constitutes active carbon and merge knot.This fusion is bolted and close active carbon and nonwoven fabric is fused into one, the thin thickness good permeability, and keep the absorption bacteriostasis strong, be easy to thermal synthesis type, environmental protection and simplification are effective, it has very strong adsorption capacity to the organic polymer material, and the micro constitutent pigment in the liquid, odorous substance etc. are had height removal ability, is convenient to make different activities charcoal product.By being sorbing material, adopt advanced technologies with high quality powdered activated carbon: forward and backward be mixed into to adopt between the net step shed the activated carbon powder step; Activated carbon powder is evenly adsorbed fusion within the nonwoven fabric matrix, make the said goods through adding HEAT SETTING again; And the forward and backward net step that is mixed into is finished by the blender and the moulded head cooperation of correspondence, this moulded head is that fiber evenly becomes net arrangement, it is as the fiber uniform distribution, provide the fibrage with air lay successively at arrival end to the port of export, its technology is simple, the easy miniaturization for the treatment of apparatus and efficient height.
