Tesnilna masa in uporaba magmatskega kamenja zanjoSealing compound and the use of magmatic stones for it

Za izbiro materijala in njegovo uporabo, naprimer pri tesnenju podnožne površine deponij, to je naprimer pri tesnenju podnožnih površin deponij proti prepuščanju vode ali tekočin v zemljo pod to površino, igra važno vlogo po eni strani stalna odpornost proti izlivu tekočin iz deponije, ki so kemijsko agresivne, po drugi strani pa odpornost na visoko odporne tekočine, ki pronicajo skozi to površino.For the selection of material and its use, for example in sealing the underfloor surface of landfills, for example in sealing the underfloor surfaces of landfills against the leakage of water or liquids into the ground below that surface, on the one hand, the constant resistance to the leakage of liquids from the landfill is chemically important. aggressive, on the other hand, resistance to highly resistant fluids that penetrate through this surface.

Za izdelavo mineralnih tesnil odnosno tesnilnih mas so znane zmesi iz kemijsko neaktivnih glinenih mineralov, ki se ne napnejo, kot so kaolinit ali ilit, kakor tudi drobljenec, pesek in gramoz.For the manufacture of mineral seals or sealants, mixtures of chemically inactive clay minerals are known which do not tense, such as kaolinite or ilite, as well as crushed stone, sand and gravel.

Njihove fizikalne sposobnosti tesnenja se lahko optimirajo na tak način, da se prostor v porah materijala izpolni s kemijsko inertnim, v začetku tekočim hidrogelom. S tem se poveča kapilarno delovanje tesnilnega materijala, kakor tudi absorbcijska sposobnost površine silikatnih mineralnih komponent materijala uporabljene zmesi mineralov.Their physical sealing abilities can be optimized in such a way that the space in the pores of the material is filled with a chemically inert, initially liquid hydrogel. This increases the capillary action of the sealing material as well as the absorption capacity of the surface of the silicate mineral components of the mineral mixture used.

Takšni hidrogeli preprečujejo tudi eventualno hidravlično ojačevanje, tako da se s tem vzdržuje naravno plastično obnašanje glinenih materijalov, brez krčenja.Such hydrogels also prevent possible hydraulic reinforcement, thus maintaining the natural plastic behavior of the clay materials without shrinkage.

Sigurnost kemijske odpornosti bazira predvsem na tesnilnem delovanju hidrogela in s tem postavlja kriterije o mineralnih materijalih, pomešanih z njim, kot nepomembne.Chemical resistance is based primarily on the sealing action of the hydrogel, thereby setting the criteria for the mineral materials mixed with it as irrelevant.

Naloga tega izuma je bila narediti tesnilo uvodoma opisane vrste, odnosno zmesi za enako uporabo, ki je bistveno izboljšana in ima poleg tega ekstremno dolgotrajno odpornostThe object of the present invention was to make a seal of the kind described above, that is, a mixture for the same use, which is substantially improved and in addition has extremely long-lasting resistance

-2proti posebno močno agresivnim substancam in to na gospodarsko optimalen način.-2 against particularly aggressive substances in an economically optimal manner.

Raziskave so presenetljivo pokazale, da je usodnega pomena prisotnost nečistoče posameznih mineralnih materijalov, ki so obdani s hidrogelom, da je tesnilo lahko odporno tudi na najagresivnejše materijale, pri čemer je potrebno upoštevati tudi sinergijska odnosno kombinirana delovanja različnih agresivnih materijalov.Surprisingly, research has shown that the presence of impurities of certain mineral materials, which are surrounded by hydrogel, is crucial, that the seal can be resistant to even the most aggressive materials, taking into account the synergistic or combined action of various aggressive materials.

S tem je izum označen s tesnilno maso, ki se lahko uporabi na posebne načine tudi pri najbolj agresivnih tekočinah, ki pritečejo in to z uporabo kombinirane zmesi iz deleža glinene moke okrog 15 % teže, najboljše z velikostjo zrn 0/09 mm, poleg tega iz enega dela mineralov ali kamnov deleža okoli 85% teže, najbolje z velikostjo zrn okrog 0/8 mm do 0/32 mm ali največ 0/63 mm in hidrogelom za tesnenje por deleža nekaj % teže, ob izboru mineralnega odnosno kamenega dela posebno magmatskih kamenin brez karbonatov.This invention is characterized by a sealant that can be used in special ways even with the most aggressive flowing liquids using a combined mixture of clay flour about 15% by weight, preferably with a grain size of 0/09 mm, in addition from one part of minerals or stones, about 85% by weight, preferably with a grain size of about 0/8 mm to 0/32 mm or a maximum of 0/63 mm and a hydrogel to seal the pores with a proportion of several% by weight, in the selection of mineral or stone parts especially magmatic carbonates free of carbonates.

V posebno ugodni ali ekonomični varijanti se mineralni odnosno kamniti del sestoji iz /magmatske/ odlitih kamenin, kot naprimer diabesa, portirja, bazalta ali, kar je posebno ugodno, iz globinskih kamenin, kot so granit ali podobno, pri katerem se v vsakem primeru lahko garantira vsebina karbonatov samo v sledeh. Posebno prednost se ustvari takrat, ko je skupni delež mineralov v tesnilnem materijalu, torej tudi v glineni moki kot naprimer koalinski glini, vsaj 75 %, premer zrna manjši od 2pm in ko je vsaj 75% kaolinskega deleža brez karbonatov.In a particularly advantageous or economical embodiment, the mineral or rock portion consists of / magmatic / cast rocks, such as diabetes, porter, basalt or, particularly advantageously, deep rocks such as granite or the like, in which any case may be carbonate content is only guaranteed in trace amounts. A particular advantage is achieved when the total mineral content of the sealing material, ie the clay flour, such as, for example, kaolin clay, is at least 75%, the grain diameter is less than 2pm, and when at least 75% of the kaolin content is carbonate-free.

Posebna lastnost v smislu tega izuma, ki preseneča v neprisotnosti karbonatov, se lahko nepričakovano izkaže kot prednost v smislu, da se kljub vplivu kislin celo pod pritiskom, ustvarja plin CO₂, ki pa ne povzroča odstopanja površine, ki ščiti pred agresijo kemijskih substanc, s čimer se preprečuje pojavljanje eventualnih zračnih mehurjev in razpok.A particular feature of this invention, which is surprising in the absence of carbonates, may unexpectedly prove to be the advantage that, despite the influence of acids, even under pressure, it produces CO ₂ gas, which, however, does not cause a surface deflection that protects against the aggression of chemical substances, thus preventing any air bubbles and cracks from appearing.

Potrebno homogenost zmesi se doseže s predelavo v običajnem dvoosnem mešalcu z gnetenjem.The necessary homogeneity of the mixture is achieved by processing in a conventional two-axis blender by kneading.

Kot uporabni inertni hidrogel se lahko uporabi DYNAGROUT-GEL firme Huls, ki v smislu izuma ustvarijo s površino magmatskih oz. globinskih kamenin zelo močno povezavo, kiAs a useful inert hydrogel, Dulsagrout-Gel from Huls can be used, which according to the invention is created by the surface of magmatic or deep rocks very strong connection which

-3preprečuje prodor tekočine, ki pritečejo čez mejno površino, hkrati je tudi odporen na kemikalije in mehanično konzistenten. Prav tako se s tem povečuje tudi absorbcija površine kamenja različnih škodljivih materijalov na podoben način, kot pri kaolinitskih in ilitskih površinah, tako da se ob tem da ni karbonatov ovlaženih odnosno ovitih mineralnih sestavnih delov, doseže dodatno varnost, kar omogoča posebno zaščito v pogledu varnosti pred najbolj toksičnimi materijali, naprimer etilendihloridom /EDC/. S povečano varnostjo glede pronicanja in odpornosti na naj agresivnejše tekočine, ki pronicajo skozi, se ustvatri tudi zelo zaželjeno izboljšanje odpornosti tesnila v smislu dobe trajanja.-3 Prevents the penetration of liquids flowing across the boundary surface, it is also chemical resistant and mechanically consistent. This also increases the absorption of the stone surface of various harmful materials in a similar manner to that of kaolinite and lithic surfaces, so that, without carbonate or moist mineral components, additional safety is achieved, which provides special protection in terms of safety against the most toxic materials, such as ethylenedichloride / EDC /. With the increased security of seepage and resistance to the most aggressive seepage fluids, the highly desirable improvement of the seal resistance in terms of durability is also achieved.

Hidrogel se v pimeru proizvodov Dynarout-a sestoji iz silikatov odpornih na škodljive materijale, z anorganskim Co trdilcem ter metalno anorganskim silicijskim združevanjem /silani/, pri čemer se ti dve komponenti lahko prilagodita tako, da se posebej z vodno razgraditvijo lahko naredijo zelo gosti hidrogeli nizke alkalnosti in viskoznosti in visokim odnosom SiO₂/Na₂O. Pri tem se lahko iz 30% vodnega stekla in okrog 60% prostornine vode formira silikatni gel, ki je odporen na škodljive materijale.The hydrogel in Dynarout's product mix consists of silicates resistant to harmful materials, with an inorganic Co hardener and metallic inorganic silicon coupling (silanes), and these two components can be adjusted so that particularly dense hydrogels can be made specifically by aqueous degradation. low alkalinity and viscosity and high SiO ₂ / Na ₂ O ratio. A silicate gel resistant to harmful materials can be formed from 30% water glass and about 60% water volume.
