Description
The present invention relates to a kind of be used to the purify method of the interior space that is loaded with harmful substance and employed for this reason material.
Because growing environmental consciousness and high-sensitive analytical method, the infringement that our environment causes because of harmful substance, the public solve more and more clearer.Produce a kind of high requirement for the building that is loaded with harmful substance or odoriferous substance, promptly eliminate these harmful and materials odorous with the least possible spending.In addition, for the needs that purify or in order to understand purification effects, people recognize and must define existing of harmful substances with simple method.Here said harmful substance is meant the material that the people has been caused spread effect, allergy or disease with trace.Timber preservative for example is as pentachlorophenol (PCP) and fortified benzene hexachloride; Plasticizer is as polychlorinated biphenyl (PCB); Perhaps also has formaldehyde; The latter and just uses in particieboard, and has been included into the material of carcinogenic suspicion.In addition, for example may volatilize hydrocarbon from paint, coating or adhesive, be aromatic hydrocarbon or its chlorinated derivatives sometimes, and they also are the harmful substances of definition mentioned above.
Debatable especially harmful substance is PCB, and it for example is used in joint sealers especially using by the prefabricated component building construction time as plasticizer.New understanding shows, passes in time, and PCB not only is diffused into from sealant in the contiguous concrete component, and is dispersed in the surrounding air from seam seal.By air exchange, the air of this PCB of containing spreads in the whole building.These are by the PCB that discharges in the seam stuffer (being a so-called source), partly with particle coagulation in the interior space, and major part is dissolved in wall pigment and the plastics.This just causes, and after some times of release, forms a series of so-called secondaries and distributes the source, is meant the metope and the ceiling surface of application here especially.So a large amount of PCB is generally contained in this secondary source of distributing, and shows so big face that distributes, so that remove the seam padding individually the PCB concentration in the room air is dropped to below the predetermined value.
Carpet is the possible harmful and odoriferous substance source of another one.For example, by under the influence of the composition of moisture and/or primer, the raw material of these products react and produce and distribute.Even after removing floor coating, the floor still continues to distribute scent of and harmful substance, to such an extent as to up to now, must remove whole floors or must lay the intermediate floor that the band back side ventilates.
Another is beastly, also be that the source of distributing of distributing of being harmful to health is the additive itself that adds in construction material sometimes.For example many buildings suffer the puzzlement of ammonia volatilization, and these ammonia volatilizations are owing to using ammonium salt, urea or organic amine, and they are widely used for the antifreezing agent as concrete and mortar.In addition, be also pointed out that over as the reason of amine volatilization and to use the house for example to carry out animal feeding, this animal feeding meeting causes, and building element is absorbed with harmful substances from air in long-time.When removing these substance sources, when for example a cancha being reconstructed into house or building for commercial use, these materials come out once more from secondary source, metope and ceiling face.This situation, from the angle of reason and effect, similar with the problems referred to above that are loaded with the PCB existence.
Announced a kind of method that is used to purify the room that is loaded with harmful substance among the DE-A-3818993.But it is to purify the room air that is loaded with harmful substance.This is to realize by following suitable measure, promptly with manual method or only by self circulation air is flow through along adsorbent.The air that for example is loaded with harmful substance is forced through the adsorption tower of filling adsorbent.The another kind of possibility of knowing therefrom is, air is along the large-area supatex fabric (F1 chengebilden) that adsorbent is housed, for example curtain and flowing through.But this method has conclusive shortcoming, promptly only is applicable to the room air that has contained harmful substance.This just causes, and the air that purified mixes with the air that is loaded with harmful substance repeatedly, therefore can only play a kind of effect that waters down at most.
Having described a kind of possibility that is used to eliminate the joint seal agent that contains harmful substance in DE-OS 4028434, is by suitable measure excision sealant, i.e. source, and it is removed.But this method can only be treated the source one time.As mentioned above, from secondary source, promptly the harmful substance of wall surface and ceiling also can be full of in the room air by the utmost point significantly; Can not eliminate these secondary sources with said method.
The purpose of this invention is to provide a kind of method that is used to purify the interior space that is loaded with harmful substance.This purpose is achieved in that promptly and directly covers the above-mentioned source of distributing with a kind of material that described material contains granule for absorbing.Its main advantage is, by stoping harmful substance to pass cover layer according to suitable material of the present invention and thereby stoping harmful substance to be transferred in the room air.Therefore, method of the present invention is to set up a step, eliminates the source of distributing that is loaded with harmful substance, and it earlier purifies in advance than method well known in the prior art.Therefore use method of the present invention, can prevent fully that harmful substance from entering room air, perhaps can stop the formation secondary to distribute the source, and described so far method, just based on from the room air that is loaded with harmful substance, removing harmful substance.
Be coated with two conclusive advantages fully according to the present invention source of will distributing: do not have harmful substance to enter the interior space again and adsorb in the highest place of concentration of narmful substance.
Adopt method of the present invention, for example can reduce the radon concentration in the dwelling house greatly, the dense room of radon can meet the limiting value that helps healthy precautionary measures before making.
A kind of embodiment of the inventive method is that contiguous member or the object that once distributes the source additionally covered with the material that contains absorbed portion.This covering should stop harmful substance to be overflowed, and harmful substance is following effusion, promptly is diffused in the contiguous member from the harmful substance of once distributing the source, and can enters in the room air when moving to this member surperficial.
In another embodiment of the invention, above-mentioned material is selected from foamed material, nonwoven, the inorganic and organic bond of perforate.The thick open-cell foam materials of particularly a kind of 0.5-5mm of this material, the preferably a kind of granule for absorbing of fine grinding and PU-foam that netted decorative pattern is arranged of adhesive of containing.Same good is that this material can contain the nonwoven that a kind of 0.1-2.0mm is thick, contain granule for absorbing and adhesive.According to another embodiment, this material is a kind of coating, and mortar, sound absorption mortar or sand finish material wherein contain granule for absorbing.
Same good is that the material that the present invention contains granule for absorbing is a carpet.The back coating of preferred carpet substrate.
The term adhesive is meant and is used for all material that identical or dissimilar materials are bondd mutually.So under mortar situation of the present invention, these materials for example are all non-hydraulics, hydraulic and adhesive potential hydraulic (gypsum, waterglass, magnesite cement, anhydrite, magnesium oxide adhesive, white lime, the water lime, cement, blast furnace slag or the like).Under open-cell foam materials and nonwoven situation, adhesive for example is all natural or synthetic materials, these materials tie up to as solution, dispersion liquid, fused mass or liquid reactions plastic body and make (for example by appropriate resin and plasticizer, pigment and inserts are also arranged sometimes) afterwards, be used for various materials are combined.
Verified especially such composition is good for a kind of mortar that contains granule for absorbing or sand finish material being used for method of the present invention, and said composition is useed the sound insulation mortar simultaneously as.One of its reason probably is high porosity, and this high porosity may produce a kind of good accessibility for adsorbent.General this mortar is that the form with the drying composite of the granule for absorbing that has maximum 50% (weight) provides, before use the furnishing pasty state.Equally, the floor that needs to purify also can cover with a kind of additional sand finish material by method of the present invention, and this sand finish material contains the granule for absorbing of maximum 50% (weight).
The inventive method also has a kind of embodiment, and promptly adsorbent also be introduced into and sticks with paste in the binding agent for wall-paper.This adhesive for example can be made up of 40% ethyl acrylate dispersant, adds the active carbon that grind and that suspend in water of 60% (weight) in dispersant.It is thick to be coated with about 300 μ m with this adhesive on wall and ceiling, covers a kind of traditional wallpaper on this coating.This adhesion is good.
If use as adsorbent, just obtains white monochrome to the insensitive molecular sieve of moisture, can arbitrarily add pigment.For fear of owing to the not enough local weak part that produces of quantity of sorbent, must control coating layer thickness effectively.
Adsorbent also can not be added to be stuck with paste in the binding agent for wall-paper, but it is added in the coating, applies this coating with enough thickness then.In this case, owing to apparent reason, use active carbon hardly and be to use molecular sieve.In addition, coating is particularly suitable for covering irregular or irregular object (cable, pipe) or breach.When manufacturing is used for the material of the inventive method, should note in adhesion material or adhesive, should not containing the material that can be adsorbed the particle absorption.Skilled in the art will recognize that suitable solution, do not need to further specify at this.But suggestion is determined for example selection of adhesive by blank test.
The another embodiment of the inventive method is, the material that has granule for absorbing is a wallpaper, on this wallpaper, cover be filled with granule for absorbing, be PU foam netted, 1-5mm.This foam is preferably extruded with a kind of mixture of being made up of active carbon that grinds and adhesive dispersion liquid, and carries out drying.Reach 200g/m at the most in this case
2Charcoal reinforced, wherein be as the criterion in dry matter, the ratio of adhesive/charcoal can be changed to 1: 5 from 1: 1.
Another embodiment of the invention is, the material that contains granule for absorbing is a kind of carrier layer that is made of surperficial carrier material, described surperficial carrier material is selected from paper, wallpaper or supatex fabric, for example textile, knit goods, nonwoven or glass fabric are coated in granule for absorbing on this carrier layer.This carrier layer and particle disposed thereon preferably form a kind of test band, and this test band is coated in and is used for measuring the release conditions that environmental poisonous substance passes the destruction on barrier layer or is used for measuring environmental poisonous substance on building element covering or that do not cover.
A kind of flat support materials that contains activated carbon granule existing description in EP-A118618 and EP-A90073 that can be used for the inventive method.
With respect to the source of distributing, thisly not only can outwardly but also can use inwardly according to test band of the present invention and adsorbent, for example be the situation in order to find to pass the wallpaper with characterization of adsorption or to pass the floor coating with characterization of adsorption under latter instance.As the test band, adopt the band that contains have an appointment 0.5g active carbon, 20 * 100mm to prove and very conform with purpose and easy to use.A kind of embodiment of the present invention is made up of a kind of double size band, and its one side covers with granule for absorbing, and covers with a kind of silicide protection paper that takes off before use at another side.This band is encapsulated in the airtight crust, and this crust protection active carbon is until use, and this crust also is used to send back to assay office.This band can for example be contained in the downside of chair, desk by light pressure, and also can take off again.
It is the purge cases that monitoring is loaded with the house of harmful substance that the another kind of this test band is used, and can make an explanation to this in one embodiment.As described above, because the pollution in wide area of the volatilization causing of the PCB in the dull and stereotyped building element wall and ceiling can be offset this pollution by covering contaminated surface with the wallpaper that contains active carbon.Conforming with purpose at this is, can know in time that PCB passes the issuable destruction of wallpaper.For this purpose, the test band is attached on the surface of wallpaper of absorption, makes its granule for absorbing towards wall one side.For this reason, preferably use (on whole, overlapping 1cm) bonding band a kind of and test band overlap joint, so that adsorption layer does not contact with adhesive.A barrier layer is set can adding towards the one side of the interior space, aluminium foil for example is to improve the effectiveness of band.
Distribute the floor or the floor covering of odoriferous substance and harmful substance with regard to purifying, a kind of embodiment of the inventive method is, between contaminated floor or floor covering and new carpet or another new floor covering, lay one deck or a kind of material, be adsorbed with odoring substance and harmful substance by it.With regard to this according to method of the present invention, for example on a kind of carrier material of flexibility, come the adsorbent bonded particulate shape or spherical, preferably active carbon by the coherent substance that is pressed into point-like, also porous polymer, and can cover through the textile material of air with a kind of.A kind of flat support materials that contains activated carbon grain existing explanation in EP-A118618 and EP-A90073 that can be used for this method of the present invention.
Another possibility is, a kind of coating that can permeate water steam is set on carrier material, and this coating plays the effect of the adhesive of adsorbent.Adsorbent spreads in this coating, after drying, covers the formed layer that contains adsorbent with a kind of light supatex fabric.By this full face coat, additional barrier layer also is housed except that adsorption layer, this barrier layer can allow floor " breathing " because of its permeable steam.Using a kind of is not the sorbing material of carpet base part, allows to lay on this material all carpet substrates arbitrarily subsequently.But this adsorbent also can be set directly in the carpet substrate.Prerequisite to this is a kind of senior back coating, and this back coating also is a bonding material for adsorbent simultaneously.This back coating can add by a kind of light supatex fabric and cover.In this working method, adsorbent preferably freely uses between 70-80% at least to 50%.This has advantage for adsorption dynamics adsorption kinetics, because adhesive phase does not need diffusion.In contrast to this, active carbon, for example with the active carbon in the powder type adding back coating, because the accessibility of the outer surface that reduces, effect is less better.
The another embodiment of the inventive method is, the material that contains granule for absorbing is a composite, this material is made up of following part: a kind of carrier layer of being made by flat support materials, a kind ofly be present in layer on this carrier layer, that contain granule for absorbing, and a kind of cover layer that is coated on this layer that contains granule for absorbing.Above-mentioned flat support materials is selected from paper, wallpaper stripper or supatex fabric (textilen Fl chengebilden), for example textile, knit goods, nonwoven or glass fabric.This shows that this composite has a kind of laminated construction of being made up of carrier layer, granule for absorbing and cover layer.Granule for absorbing preferably is coated on the carrier layer by a kind of preparation that contains bonding material.This bonding material relates to organic bond, the bicomponent system of especially a kind of plastic dispersing agent or a kind of few solvent, and perhaps it is selected from latex class, for example Heveatex.This preparation that contains bonding material can be used as the point-like coating or applies as full face coat.Because for the reason of building structure, the water penetration and the air permeability of the material relevant with building industry play an important role, and therefore, especially under the situation of full face coat, bonding material should form permeable steam.
At the employed cover layer of the material that is used for the inventive method is a kind of flat support materials, and this flat support materials is selected from paper, wallpaper stripper or supatex fabric, for example textile, knit goods, nonwoven or glass fabric.This cover layer preferably can be laminated on the material that contains granule for absorbing with a kind of bond vitrified agent point or a kind of thin bond vitrified agent skin.
The composite that is used for the inventive method for example can be made by following process: give the full face coat that a kind of permeable steam is set towards indoor carrier (supatex fabric, dedicated paper or glass fabric), this coating also is a bonding material for granular or spherical adsorbent simultaneously.This coating sprinkled adsorbent before drying.The superfluous thing of sucking-off.Then adsorption layer is for example covered with a kind of light textile fabric, in order that protect it not to be subjected to the influence of binding material, composite is bonded on the building element by adsorption layer.Preferably being suitable as tectal is light, that mesh is fine and closely woven and polyester non-woven fabric that have the bond vitrified agent that stamps.
This full face coat has crucial advantage: both made when using open weaving carrier material, also can brush color to this carrier material, make the not sorbent suspension infringement of wall color, perhaps the mode with any other can not enter for the harmful substance that will adsorb.The Impranile or the Imprapermtypen that can for example have Plextole that R hm Co., Ltd produces or Bayer joint-stock company to produce in order to the dispersant of the coating of making permeable steam.
Another kind of possibility; promptly protect granule for absorbing not permeated by pigment at the material that is used for the inventive method; its structure is as follows: the carrier layer of adsorbent turns to wall; and adsorbent itself covers with cladding material; wherein, between adsorbent and cladding material, use a kind of bond vitrified agent-slit paper tinsel as the bonding band.Therefore can moisture fully be oozed out, but pigment is oozed out.But should preferably use few solvent or solvent-free pigment for coating.
In another embodiment of the invention, on the one side in the source of distributing dorsad of composite, a kind of additional barrier layer is set on carrier layer or cover layer promptly, barrier layer that preferably can permeate water steam.This barrier layer generally is coated on the one side in the source of distributing dorsad of adsorption layer in composite inner.
The invention still further relates to a kind of sorbing material, this material comprise a kind of as permeable steam the barrier layer and the flat support materials and a kind of layer that contains granule for absorbing that is present on this flat support materials that form.Can comprise an additional cover layer according to this sorbing material of another embodiment of the present invention, this cover layer is arranged on the layer that contains granule for absorbing.
The sorbing material another kind of of the present invention that forms with composite comprises: a kind of flat support materials, a kind of barrier layer of disposed thereon, additional permeable steam and a kind ofly be positioned at layer on the barrier layer, that contain granule for absorbing.According to another embodiment of the present invention, this sorbing material comprises an additional cover layer, and it is arranged on the layer that contains granule for absorbing.
The barrier layer task is, increases the time of contact of harmful substance and adsorbent, the harmful substance that slows down from the source of distributing to the migration velocity of composite material surface.Another advantage on this barrier layer is that volatile a little less than preventing, the gas that can adsorb is enduringly moved in the adsorption layer from room air and reduced suction-operated, for example to the suction-operated by the radon of overflowing in the wall.When using supatex fabric porous, that can see through air, preferably use this barrier layer as carrier material.Breathe in order not suppress walling, but a kind of like this barrier layer conforms with purpose permeate water steam.
For granule for absorbing, the barrier layer can be a bonding material simultaneously.This barrier layer also can be made up of the slit paper tinsel on a kind of outer field inboard that is bonded in composite, preferably is made up of a kind of bond vitrified agent-slit paper tinsel, and this paper tinsel combines with granule for absorbing at another side.In another embodiment, the barrier layer can be latex coating or latex pigment coated (Latexfarbanstrich), it be coated in composite on indoor lateral surface.
About utilizing method absorption radon of the present invention, the result shows, uses a kind of bond vitrified agent-slit paper tinsel as the barrier layer, and by means of this barrier layer, cover layer laminated outside, chamber one side is very effective on adsorption layer.According to laminated temperature, it is about 90% that air see through to reduce, and significantly improved the absorption of radon simultaneously.In the case, moisture can pass through fully, therefore can not occur the danger of moisture accumulation in walling.The another kind of method that is used to adsorb radon of the present invention is to use a kind of material, but a kind of coating of permeate water steam is set on the back side of cladding material in this material, this coating for absorbent particles or adsorbent spherolite simultaneously as tack coat.Adsorption layer upper strata unification kind of the cover layer that forms after overwrite procedure, this cover layer for example can be fabric or paper.In the above two kinds of cases, radon at first contacts with adsorption layer.At this moment, radon also is not adsorbed fully, and the part radon rushes at the barrier layer, is blocked layer and stops, and therefore can continue adsorption process.
In another embodiment of the inventive method and sorbing material of the present invention, the face towards the source of distributing of material or composite (carrier layer or cover layer) is a kind of separating layer, its task is can remove composite, thereby so that finally remove from the source of distributing and also carry out the refuse eliminating.Here said removal is interpreted as, and especially the granule for absorbing that combines with carrier layer can be complete, and removes from the source of distributing, preferably a kind of stripping of this separating layer layer paper or a kind of stripping layer nonwoven, or form by two kinds of segregative nonwoven.
The inventor's actual tests shows, under PCB was adsorbed on situation on the active carbon, because suitable adsorption equilibrium, by " sucking-off ", this wall did not almost have PCB after the several years from the PCB of the source of distributing (for example contaminated wall).Separating layer especially has this task at this, promptly for example can tear wallpaper stripper from the source of distributing with simple method, so that wallpaper stripper is sent to the place of the elimination that is fit to harmful substance, for example specific refuse is burned.At this moment, should as far as possible fully collect the adsorbent that contains PCB.For reaching this purpose, weak link (plane of weakness) must be embedded in the composite of carrier material or wallpaper.This possibility provides the structure of following model: the cladding material of weaving is being loaded with absorbent particles on the face of wall, these absorbent particles stick on the textile material with a kind of binding agent of discontinuous coating.Adsorbent is covering with stripping layer paper aspect this.Stripping layer paper has gluing surface preferably, but gluing hardly in inside, is strippable therefore.When tearing, keep half on the wall, can be used as the new bottom of sticking with paste wallpaper, and second half continues to cover adsorbent, so avoid the entire loss of adsorbent.
Another kind of possibility for example tears the paste wallpaper off the free of losses adsorbent, and it is enough to make the coating of adsorbent towards wall doughtily, so that do not tear coating when tearing the paste wallpaper.Preferably at first can make the binding agent substrate moistening.
An advantage of above-mentioned composite normally, the nuisance mass-energy in adsorption layer freely moves until absorption.According to the special nature in the source of distributing, local strong excessively harmful substance may occur and overflow, so because barrier layer or laminated construction, harmful substance can (not having local overload) extending transversely in the clear in adsorption layer.On all directions, there is a large amount of operational adsorbents all the time, harmful substance can evenly be distributed.When a kind of sealing by fusing does not add adsorbent, for example use a kind of aluminium foil sealing by fusing, migration and big breach just appear when damage.
In contrast, for example the damage of the little part of the composite of the present invention that causes with holing is fully harmless, because for example the effect of the wallpaper stripper of adsorptivity is based in conjunction with the harmful substance of distributing in the very short distance in source, rather than is defined in covering fully of a kind of full surface.
The another embodiment of the inventive method is, the material that contains granule for absorbing exists with strips, and this band for example covers on the seam with the encapsulant sealing that contains hazardous substance, perhaps puts in this seam.This band preferably covers with a kind of material that is suitable for the inventive method again, so that definitely get rid of the possibility that harmful substance enters the interior space reliably.Because joint sealers generally is the position of certain depth of packing into, so, enough positions are arranged for the thick strip of sorbing material; In this groove, a large amount of granule for absorbing can be laid, therefore after the several years, also this reliability can also be guaranteed.
Stampings or porous polymer that the granule for absorbing that can be used for or be applicable to the inventive method and sorbing material of the present invention is the pebble coal, hydrophobic molecule sieve of ion-exchanger, the asphaltic base of pulverous active carbon, activated carbon pellets, activated carbon granule, carbonization and activation, become by the hydrophobic molecule sieve series.Granule for absorbing, particularly active carbon preferably have 900m at least
2The inner surface of/g.Activated carbon pellets or activated carbon granule preferably have the diameter of 0.1-2.0mm, particularly 0.3-1.0mm.Granule for absorbing is preferably with 5-400g/m
2, 10-250g/m particularly
2Amount exist.
The preparation of the ion-exchanger of carbonization and activation has been described in DE-A4304026.Material of the present invention generally contains the granule for absorbing of maximum 70% (weight).
There are many methods can be suitable for granule for absorbing for example is placed on the carrier material.Therefore for example as described in the DE-A3211322, adopt and execute the commentaries on classics serigraphy and will be printed as fritter by the paste that active carbon and adhesive dispersion liquid are formed, in the case, coating is the highest can to reach 100g/m
2Use the existing explanation in DE-A3304349 of spherical active carbon, this spheric active carbon adheres to by a kind of punctate substance that is coated on the supatex fabric.
A kind ofly be very suitable for the pebble coal that adsorbent of the present invention is an asphaltic base.Like this, for example when using diameter, on the carrier material of test band of the present invention or composite, can stack and be up to 1000 beads for every square centimeter as the pebble coal of 0.3-0.8mm.This is equivalent to be higher than 20mg/cm
2Active carbon, these active carbons are actually can be for free approaching, because the bonding material aperture of locking 10-15% only.Be 0.5-1.2nm in the aperture, especially during 0.8-0.9nm, have 1000-1200m
2The pebble coal of the inner surface of/g and the micro pore volume of 0.3ml/g is particularly well suited to method of the present invention.Importantly, micropore is more closely, because absorption affinity is the strongest in this case.Yet in order to hold the molecule of the harmful substance that is not very little, as the PCB molecule, micropore again must be enough big on the other hand.Therefore, the aperture of 0.6-1.0nm is very suitable.People have found such aperture in the active carbon of the active carbon of the active carbon (pebble coal) of for example asphaltic base, cocoanut shell base and some bituminous coal base.Harmful substance is adsorbed consumingly and is remained on for prolonged period of time in these materials.
Have granule for absorbing carrier layer even adsorption concentration for the effect of composite cause close important.When using spheric active carbon, especially to guarantee even adsorption concentration.
Except pebble coal, say in principle, also can use particulate coal or cracked coal (particle size) with 0.3-2mm.Yet pebble coal is had a preference for owing to its smooth and wear-resisting surface and with the covering that it can reach the best.
