Spôsob sanácie vnútorných priestorov alebo predmetov kontaminovaných škodlivými látkami, najmä formaldehydomMethod of remediation of interiors or objects contaminated with harmful substances, in particular formaldehyde
Oblasť technikyTechnical field
Predložený vynález sa týka spôsobu sanácie vnútorných priestorov alebo predmetov kontaminovaných škodlivými látkami, najmä formaldehydom, a pre trvalú ochranu vzduchu v priestore proti týmto škodlivým látkam.The present invention relates to a method for the remediation of interior spaces or objects contaminated with harmful substances, in particular formaldehyde, and to permanently protect the air in the space against these harmful substances.
Doterajší stav technikyBACKGROUND OF THE INVENTION
Škodlivé látky vo vnútorných priestoroch nabývajú, najmä v súvislosti so zlepšeniami v oblasti úspor energie, ktoré prinášajú značné zníženie intenzity výmeny vzduchu, zvláštny význam. Formaldehyd predstavuje ich podstatnú zložku. Je obsiahnutý predovšetkým v drevených materiáloch, najmä drevotrieskových doskách, tabakovom dyme, voskoch na parkety, farbách a lakoch, lepidlách, izolačných materiáloch a tapetách. Formaldehyd obsiahnutý v stavebných látkach sa pomaly uvoľňuje. Až doposiaľ sú známe iba dve metódy sanácie priestorov, kontaminovaných škodlivými látkami, najmä formaldehydom. Jednak sa odstraňujú kontaminované stavebné látky, čo síce sľubuje trvalý výsledok, je to však spojené so značnými nákladmi. Inou metódou odstraňovania kontaminácie škodlivými látkami je povlečenie alebo potiahnutie materiálov emitujúcich škodliviny vhodnými materiálmi, aby sa zabránilo vystupovaniu škodlivých látok. Pritom používané nátery podliehajú procesu starnutia, ktorý vedie k tomu, že doba ich účinku je obmedzená. Okrem toho existuje nebezpečie, že sa povlakom nepriaznivo ovplyvnia klimatické pomery v priestore v dôsledku zníženej alebo chýbajúcej kapacity pre pohlcovanie vlhkosti.Indoor pollutants are of particular importance, particularly in the context of energy savings improvements that bring about a significant reduction in air exchange intensity. Formaldehyde is an essential component. It is mainly contained in wood materials, in particular particle board, tobacco smoke, parquet waxes, paints and varnishes, adhesives, insulating materials and wallpaper. Formaldehyde contained in building materials is slowly released. So far, only two methods of remediation of areas contaminated with harmful substances, in particular formaldehyde, are known. On the one hand, contaminated building materials are removed, which promises a lasting result, but this is associated with considerable costs. Another method for removing contamination by harmful substances is to coat or coat pollutant-emitting materials with suitable materials to prevent the release of harmful substances. The coatings used here are subject to an aging process which leads to a limited duration of action. In addition, there is a risk that the climatic conditions in the room will be adversely affected by the coating due to reduced or missing moisture absorption capacity.
Podstata vynálezuSUMMARY OF THE INVENTION
Úlohou vynálezu je navrhnúť spôsob sanácie priestorov kontaminovaných škodlivými látkami, ktorý nemá vyššie uvedené nevýhody vysokých nákladov, časové obmedzený účinok a negatívne ovplyvnenie klimatu priestoru.SUMMARY OF THE INVENTION It is an object of the present invention to provide a method for the remediation of polluted areas which does not have the above-mentioned disadvantages of high cost, time limited effect and a negative effect on the room climate.
Táto úloha je podľa vynálezu vyriešená tak, že sa do kontaminovaného priestoru, s výhodou do blízkosti emitentu škodlivých látok, uvedú keratínové vlákna, najmä vlákna ovčej vlny.This object is achieved according to the invention by introducing keratin fibers, in particular sheep wool fibers, into the contaminated space, preferably in the vicinity of the emitter.
Proteínové vlákna (keratín) prijímajú škodlivé látky a zabudovávajú ich chemickou rekaciou do svojej štruktúry, čím sa škodlivé látky trvalé odoberajú zo vzduchu v priestore.Protein fibers (keratin) absorb harmful substances and incorporate them by chemical reaction into their structure, thereby removing harmful substances from the air in space permanently.
K tomuto slúžia keratínové vlákna, najmä vlákna ovčej vlny, ktoré sa používajú, s výhodou spojené ako rohože, dosky alebo rúna, pre vynikajúce tlmenie zvuku. Tým sa jednak dosahuje čistenie vzduchu v priestore od škodlivých látok, jednak vynikajúce tlmenie hluku.For this purpose, keratin fibers, in particular sheep wool fibers, are used, preferably bonded as mats, slabs or webs, for excellent sound attenuation. This achieves both air purification of the room from harmful substances and excellent noise damping.
Podľa vynálezu je tiež výhodné, keď sa keratínovými vláknami, najmä vláknami z ovčej vlny, pokryjú emitenty škodlivých látok.According to the invention, it is also advantageous for emitters of harmful substances to be covered with keratin fibers, in particular sheep wool fibers.
Tým je efektívne zabránené, aby sa škodlivé látky, ktoré sa môžu dostať do vzduchu v priestore, absorbovali už pri výstupe z emitentu. Naviac je tým efektívne zabránené prípadné orosovanie povrchu emitentu. Obsah vlhkosti vzduchu v priestore sa vyrovnáva veľkou absorpčnou schopnosťou keratínových vlákien.This effectively prevents any harmful substances that may enter the air in the room from being absorbed at the exit of the issuer. Moreover, any dew condensation of the emitter surface is effectively prevented. The moisture content of the space is compensated by the high absorption capacity of keratin fibers.
Podľa vynálezu je rovnako výhodné, keď sa predmet emitujúci škodlivé vlákna, napríklad skriňa, pokryje keratínovými vláknami, najmä vláknami ovčej vlny, aspoň na jednej strane, s výhodou na zadnej strane.According to the invention, it is also advantageous if the article emitting harmful fibers, for example the housing, is covered with keratin fibers, in particular sheep wool fibers, on at least one side, preferably on the back side.
Tým je dlhodobé efektívne neutralizovaná emisia škodlivých látok z predmetu. Nie je nutné vyhodenie kontaminovaného predmetu.This means that the emission of harmful substances from the object is effectively neutralized in the long term. It is not necessary to throw away the contaminated object.
Ďalšie výhodné vytvorenie spočíva v tom, že sa použijú keratínové vlákna, najmä vlákna ovčej vlny, zošité do rohoží.A further advantageous embodiment consists in the use of keratin fibers, in particular sheep wool fibers, sewn into mats.
Tak môžu byť povrchy emitentov škodlivých látok jednoducho zakryté.Thus, the surfaces of the emitters can be easily covered.
Výhodné tiež je, keď sa použijú keratínové vlákna, najmä vlákna ovčej vlny, splstených napríklad valchovaním na rohože.It is also advantageous to use keratin fibers, in particular sheep wool fibers, felt, for example, by matting on mats.
To predstavuje ďalší spôsob výroby rohoží, ktorými je možné zakryť emitenty škodlivín.This is another way of making mats that can be used to cover harmful emitters.
Ukázalo sa výhodné, keď sa použijú keratínové vlákna, najmä vlákna ovčej vlny, zošité na dosky.It has proven advantageous to use keratin fibers, in particular sheep wool fibers, sewn into boards.
Tým je možné napríklad staviace steny, priečky, stropy alebo vetracie zariadenia jednak izolovať proti prenosu zvuku a zároveň realizovať efektívne preventívne opatrenie proti príliš vysokému podielu škodlivých látok vo vzduchu v priestore, napríklad prostredníctvom cigaretového dymu alebo iných emitentov škodlivých látok.Thus, for example, building walls, partitions, ceilings or ventilation devices can both be insulated from sound transmission and at the same time take effective precautions against excessive levels of harmful substances in the air in the space, for example by means of cigarette smoke or other emitters.
Ďalšie výhodné uskutočnenie spočíva v tom, že použité spojenie keratínových vlákien, najmä vlákien ovčej vlny, je aspoň jedným povrchom spojené s nosičovým materiálom.A further preferred embodiment is that the bonding of the keratin fibers, in particular the wool fibers, is connected to the carrier material by at least one surface.
Tak môže byť vytvorené obloženie, steny alebo podobne, ktoré vedľa funkcie obloženia naviac plnia funkciu čistenia vzduchu v priestore od škodlivých látok.Thus, lining, walls or the like can be provided which, in addition to the lining function, also perform the function of purifying the air in the space from harmful substances.
Výhodné sa tiež ukázalo, keď použité spojenie keratínových vlákien, najmä vlákien ovčej vlny, je aspoň z jednej strany kašírované sádrou.It has also proven advantageous if the bonding of the keratin fibers, in particular the wool fibers, is laminated on at least one side with gypsum.
Takto vzniknuté povrchy môžu byť bez problémov natierané alebo tapetované.The resulting surfaces can be painted or wallpapered without problems.
Podľa vynálezu je tiež výhodné, keď je použité spojenie keratínových vlákien, najmä vlákien ovčej vlny, aspoň jedným povrchom spojené so sádrokartónovou doskou.According to the invention, it is also advantageous to use a bonding of keratin fibers, in particular sheep wool fibers, with at least one surface connected to the gypsum board.
Zo sádrokartónovej dosky pozostávajúci povrch steny alebo podobne môže byť pri zodpovedajúcom vytvorení tiež vo vlhkom priestore, a je vhodný tiež pre polepenie dlaždicami.A gypsum board consisting of a wall surface or the like can also be provided in a damp space, if appropriate, and is also suitable for tile covering.
Ďalšia výhodná možnosť vytvorenia spočíva v tom, že použité spojenie keratínových vlákien, najmä vlákien ovčej vlny, je aspoň jedným povrchom spojené s doskou z dreva, najmä z mäkkého dreva.A further advantageous embodiment is that the bonding of the keratin fibers, in particular the sheep wool fibers, is connected to the board of wood, in particular of softwood, by at least one surface.
Tak sú vlákenné spojenia spojené s tuhým, avšak v určitom rozsahu flexibilným nosičovým materiálom a sú preto osobitne vhodné pre zhotovenie prepravovateľných staviacich stien.Thus, the fiber connections are connected to a rigid but to some extent flexible carrier material and are therefore particularly suitable for the construction of transportable building walls.
Výhodné tiež je, keď sa použijú keratínové vlákna, najmä vlákna ovčej vlny, zmiešané s nosičovým materiálom, pričom aspoň časť vlákien zasahuje až do povrchu spojenia.It is also advantageous to use keratin fibers, in particular sheep wool fibers, mixed with the carrier material, at least a portion of the fibers extending to the bonding surface.
Tým je zaistené, že keratínové vlákna, najmä vlákna ovčej vlny, sú v priamom spojení s okolím, napriek tomu však je dostatočne vystužený nosičovým materiálom.This ensures that keratin fibers, in particular sheep wool fibers, are in direct communication with the environment, yet are sufficiently reinforced with the carrier material.
Osobitne výhodným sa ukázalo, keď sa k odstráneniu škodlivých látok použijú keratínové vlákna, najmä vlákna ovčej vlny, spolu so sádrou, vytvarovaných na dosku.It has proven to be particularly advantageous to use keratin fibers, in particular sheep wool fibers, together with gypsum molded on a board, to remove harmful substances.
Z takýchto dosiek môže byť vytvorené natierateľné obloženie stien, ktoré umožňuje sanáciu škodlivých látok podľa vynálezu.Such panels can be used to form a paintable wall lining which enables the removal of harmful substances according to the invention.
Ďalej je výhodné, keď sa k odstráneniu škodlivých látok použije zmes keratínových vlákien, najmä vlákna ovčej vlny a dreva, s výhodou mäkkého dreva.It is further preferred that a mixture of keratin fibers, in particular sheep wool and wood fibers, preferably softwood, is used to remove harmful substances.
Tak môžu byť vytvorené staviace steny, ktoré vykazujú dostatočnú tuhosť, avšak napriek funkcii zachytávania škodlivých látok neobsahujú žiadne priamo viditeľné keratínové vlákna.In this way, building walls can be formed which exhibit sufficient stiffness but, despite the function of trapping harmful substances, do not contain any directly visible keratin fibers.
