Description
Vynález sa týka hmoty na vytvorenie viacúčelovej bariéry proti znečisteniu a spôsobu vytvorenia takej bariéry.BACKGROUND OF THE INVENTION The present invention relates to a composition for forming a multipurpose anti-fouling barrier and a method of forming such a barrier.
Súčasný stav technikyThe state of the art
Je známe, že vo väčšine prípadov sa znečisťujúci odpad skladuje na haldách prekrytý zeminou. Okolo týchto háld je nutné budovať bariéry, zabraňujúce úniku odpadu, predovšetkým do podzemných vôd.It is known that in most cases the polluting waste is stored on pile covered with soil. Around these heaps, it is necessary to build barriers to prevent leakage of waste, especially into groundwater.
Rovnako je známe, že znečisťujúci odpad sa delí zásadne na dva druhy, jednak na katióny ťažkých kovov, ktoré môžu byť rádioaktívne, a na druhej strane na toxické organické zlúčeniny.It is also known that polluting waste is principally divided into two types, namely cations of heavy metals, which may be radioactive, and, on the other hand, toxic organic compounds.
Z patentu FR 81/21.025 je známa injektážna malta, použiteľná na vytváranie ochranných stien v pôde proti šíreniu rádioaktívneho odpadu, ktorá je tvorená zmesou vody, cementu, ílu a oxidu kremičitého (šilikmi). V prípade, že je silika tvorená aspoň čiastočne lietavým popolčekom, je podľa tohto patentu ďalej známe pridávať ku zmesi uhličitan sodný, ktorý pôsobí ako deflokulant pre íl a aktivátor pre oxid kremičitý.From FR 81 / 21.025 an injection mortar is known which can be used to form protective walls in the soil against the spread of radioactive waste consisting of a mixture of water, cement, clay and silica (silica). If the silica is formed by at least partially fly ash, it is further known according to this patent to add to the mixture sodium carbonate, which acts as a clay deflocculant and a silicon dioxide activator.
Tieto známe hmoty však neumožňujú vytvárať účinné bariéry proti organickým znečisťujúcim látkam.However, these known compositions do not make it possible to form effective barriers against organic pollutants.
Patent FR 84/11863 popisuje maltu, umožňujúcu v pôde vytvárať, steny, ktoré zabraňujú alebo spomaľujú migráciu kovových katiónov. Táto malta pozostáva z vody, cementu, ílu, oxidu kremičitého. uhličitanu sodného a pyrofosforečnanu sodného a/alebo vínanu draselného. Prítomnosť jednak uhličitanu sodného a na druhej strane pyrofosforečnanu draselného a/alebo vínanu draselného umožňuje tvorbu nerozpustných zlúčenín, kým uhličitan sodný súčasne pôsobí ako aktivátor oxidu kremičitého.Patent FR 84/11863 discloses a mortar allowing the formation in the soil of walls which prevent or retard the migration of metal cations. This mortar consists of water, cement, clay, silica. sodium carbonate and sodium pyrophosphate and / or potassium tartrate. On the one hand, the presence of sodium carbonate and, on the other hand, potassium pyrophosphate and / or potassium tartrate allows the formation of insoluble compounds, while sodium carbonate simultaneously acts as a silica activator.

Nevýhodou známych hmôt tohto typu je. že po dlhšej či kratšej dobe strácajú účinnosť.A disadvantage of known masses of this type is. that after a longer or shorter time they lose their effectiveness.
Patent FR 90/00087 tiež popisuje hmotu použiteľnú v pôde na vytváranie stien, schopných zabraňovať alebo spomaľovať šírenie toxických organických látok, tvorenú zmesou vody, cementu alebo hydraulického pojiva. bentonitu a aktívneho uhlia.Patent FR 90/00087 also discloses a material useful in the soil for forming walls capable of preventing or retarding the spread of toxic organic substances, consisting of a mixture of water, cement or hydraulic binder. bentonite and activated carbon.
Podstata vynálezuSUMMARY OF THE INVENTION
Predmetom vynálezu je hmota na báze vody, cementu a ílu. umožňujúca vytvárať bariéru s dlhou životnosťou proti šíriacim sa látkam, tvoreným ako katiónmi kovov, predovšetkým ťažkých kovov, tak organickými produktami. Podstatou tejto hmoty je skutočnosť, že ďalej obsahuje aktívne uhlie a rozpustnú zásaditú soľ, schopnú tlmiť vodnú fázu tejto hmoty na pH aspoň 9 po dobu aspoň okolo 10 rokov.The subject of the invention is a water, cement and clay based material. allowing the formation of a long-lasting barrier against the spreading substances formed by both metal cations, especially heavy metals, and organic products. The essence of this composition is that it further comprises activated carbon and a soluble basic salt capable of buffering the aqueous phase of the composition to a pH of at least 9 for at least about 10 years.
Vodnou fázou hmoty sa rozumie intersticiárna kvapalina, ktorá v hmote zostáva po vyvolaní jej tuhnutia a vytvorení bariéry proti znečisteniu.The aqueous phase of the mass is understood to be the interstitial liquid which remains in the mass after inducing its solidification and forming a barrier against contamination.
Podľa vynálezu zásaditá soľ musí jednak udržovať vo vodnej fáze pH vyššie než 9 a na druhej strane musí byť v hmote prítomná v dostatočnej koncentrácii na dlhodobé zaistenie tejto funkcie po dobu aspoň 10 rokov, výhodne 50 až 100 rokov.According to the invention, the basic salt must, on the one hand, maintain a pH greater than 9 in the aqueous phase and, on the other hand, must be present in the mass in sufficient concentration to provide this function for at least 10 years, preferably 50 to 100 years.
Aktívne uhlie môže byť podľa vynálezu známeho typu, napríklad produkt spoločnosti CECA, predávaný pod názvom Aktlcarbon TK.The activated carbon may be of a known type according to the invention, for example a CECA product sold under the name Aktlcarbon TK.
Tlmlvá soľ podľa vynálezu môže byť tvorená napríklad' uhličitanom sodným alebo hydrogénuhličitanom sodným (NÄ2C03 alebo NalICCh ). ktorý je prítomný, alebo ďalej páleným alebo haseným vápnom (CaO alebo CA10H12) v množstve, dostatočnom na zaistenie tlmivého účinku.The buffer salt of the invention may be formed, for example, by sodium carbonate or sodium bicarbonate (Na 2 CO 3 or NaCl 3). which is present or further burnt or slaked lime (CaO or CA10H12) in an amount sufficient to provide a buffering effect.
Hmotnostne pomery zložiek hmoty sú podľa vynálezu výhodne nasledovné: The weight ratios of the components of the mass according to the invention are preferably as follows :
Podľa vynálezu môže hmota poprípade obsahovať oxid kremičitý. napríklad sublimovaný oxid kremičitý alebo lietavý popolček, napríklad v hmotnostnom pomere 25 až 1500 kg na 1000 1 vody. Táto prísada umožňuje, ako je známe, znížiť priepustnosť hmoty.According to the invention, the composition may optionally contain silica. for example, sublimed silica or fly ash, for example in a weight ratio of 25 to 1500 kg per 1000 L of water. This additive makes it possible, as is known, to reduce the permeability of the mass.
Hmota podľa vynálezu môže ďalej obsahovať známe prísady, napríklad zmáčadla, ako je naftalénsulfonát, v hmotnostnom pomere až 20 kg na 1000 1 vody, alebo spomaľovače, ako je 1 ignosulfonát sodný, v hmotnostnom pomere ,až 50kg na 1000 1 vody, alebo zmäkčovadlá, znižujúce obsah vody, ako je produkt, predávaný fou Chryso pod názvom Cerplast, v hmotnostnom pomere až 30 kg na 1000 1 vody.The composition according to the invention may further comprise known additives, for example wetting agents, such as naphthalenesulfonate, in a weight ratio of up to 20 kg per 1000 l of water, or retardants, such as sodium ignosulfonate, in a weight ratio of up to 50 kg per 1000 l of water, or plasticizers. a water-reducing product such as the product sold by Chryso under the name Cerplast, in a weight ratio of up to 30 kg per 1000 l of water.
Ilinota podľa vynálezu môže taktiež obsahovať soli, zrážajúce kovové katióny, ako je vínan sodný a/alebo pyrofosforečnan sodný, v hmotnostnom pomere až 20 kg na 1000 1 vody.The liner according to the invention may also contain salts, precipitating metal cations, such as sodium tartrate and / or sodium pyrophosphate, in a weight ratio of up to 20 kg per 1000 l of water.
V konkrétnom vyhotovení obsahuje hmota podľa vynálezu agregáty, ako je piesok alebo štrk, umožňujúce získať maltu alebo betón s vynikajúcimi vlastnosťami bariéry proti znečisteniu.In a particular embodiment, the composition of the invention comprises aggregates, such as sand or gravel, to obtain mortar or concrete having excellent anti-fouling barrier properties.
Vďaka svojmu intersticiárnemu tlmivému roztoku, ktorý zaisťuje pH aspoň 9, výhodne medzi 9 a 12, je hmota podľa vynálezu charakterizovaná zaistenou a uchovanou dlhodobou nerozpustnosťou katiónových znečisteniu a vylúčením ich neskoršieho obnoveného uvoľňovania.Due to its interstitial buffer, which ensures a pH of at least 9, preferably between 9 and 12, the composition according to the invention is characterized by the secured and preserved long-term insolubility of cationic contaminants and the elimination of their later sustained release.
Hmoty podľa vynálezu môžu mať formu samotuhnúcich mált, plastbetónov alebo tvrdých betónov.The compositions of the invention may take the form of self-setting mortars, plastics or hard concrete.
Umožňujú budovať tradičnými metódami v pôde nepresakujúce steny proti šíreniu znečisťujúcich látok.They make it possible to build non-leaking walls against the spread of pollutants by traditional methods in the soil.
Rovnako umožňujú injektovaním vypĺňať dutiny v pôde proti šíreniu týchto znečisťujúcich látok.They also allow injection into the voids in the soil to prevent the spread of these pollutants.
Hmoty podľa vynálezu konečne umožňujú budovať betónové schránky na uchovávanie odpadu a rovnako ďalšie stavby tohto druhu, ako sú steny, skladovacie kontajnery apod.Finally, the materials according to the invention make it possible to build concrete waste storage boxes as well as other constructions of this kind, such as walls, storage containers and the like.
Ďalším predmetom vynálezu je spôsob zhotovovania bariér proti znečisteniu, spočívajúci v tom, že do pôdy sa leje alebo injektuje tuhnúca hmota, napríklad vyššie popísaného typu.Another object of the present invention is to provide a method for making soil barriers by pouring or injecting a solidifying material of the type described above into the soil.
Obmena spôsobu spočíva v zhotovovaní schránok, stien alebo skladovítcich kontejnerov pomocou tejto hmoty.A variation of the method consists in making receptacles, walls or storage containers with this mass.
