Description
Područje u kojem se izum nalazi The area where the invention is located
Solidifikati su produkti fizikalno-kemijske preradbe tvari i supstancija, kojima je konačni produkt karakteriziran oblikom svog stanja i to kao suhog praha, manje ili veće gustoće i granulacije, te koji uglavnom ne sadrže vlagu ili je ona neznatna, u tragovima ili je uopće nema. Solidifieds are products of physico-chemical processing of substances and substances, whose final product is characterized by the shape of its state as a dry powder, of greater or lesser density and granulation, and which mostly do not contain moisture or it is insignificant, in traces or not at all.
Prema ovom izumu, solidifikati, koji se pripremaju za inertizaciju, neutralizaciju i imobilizaciju odnose se na one solidifikate, koji nastaju iz fizikalno-kemijske preradbe materijala koji u sebi sadrže ugljikovodik, odnosno i onih koji nastaju iz drugih procesa preradbe organsko-anorganskih tvari i supstancija, a u cilju povećanja njihove stabilnosti, smanjenja polutanata i toksičnih tvari u eluatu i njihova pretvorba u stanje inaktivnosti, netopljenja, neraspadanja, odnosno nepromjenjivosti svojstava i postojanog stanja u vrlo velikom vremenskom razdoblju. According to this invention, solidifieds, which are prepared for inerting, neutralization and immobilization refer to those solidifieds, which are created from the physical-chemical processing of materials containing hydrocarbons, that is, those that are created from other processing processes of organic-inorganic substances and substances , and with the aim of increasing their stability, reducing pollutants and toxic substances in the eluate and their transformation into a state of inactivity, non-melting, non-decomposition, i.e. immutability of properties and stable state for a very long period of time.
Prema međunarodnoj klasifikaciji patenata (MKP) izum spada u područja: C 02; C 08; C 10; G 21 F, G; B 01 J; F 26 B. According to the International Classification of Patents (IPC), the invention belongs to the following areas: C 02; C 08; C 10; G 21 F, G; B 01 J; F 26 B.
Tehnički problem Technical problem
Solidifikati uobičajeno imaju različita obilježja, karakteristike i svojstva, po kojima se međusobno razlikuju i prema kojima se identificiraju kao: a) solidifikati za korištenje u dalje preradivačke svrhe u industriji; b) solidifikati kao produkti preradbe za korištenje u daljim tehnološkim postupcima; c) solidifikati kao nus-produkti tehnoloških ili fizikalno-kemijskih postupaka obradbe; d) solidifikati kao konačni ekološki produkti kojima se prethodno smanjuje toksičnost, otrovnost ili štetnost po prirodu i okoliš; e) solidifikati koji predstavljaju materijalnu komponentu daljih tehnoloških postupaka, fizikalno-kemijskih i mehaničkih obradba, te f) solidifikati za pripremu iskorištavanja u tehnološkim procesima ili za iskorištavanje u građevinarstvu, cestogradnji, ili g) za iskorištavanje u području dobivanja tehničkih zaštitnih materijala za izgradnju barijera protiv agresivnih i štetnih utjecaja drugih materijala (npr. radionuklida) itd. Solidifieds usually have different features, characteristics and properties, by which they differ from each other and according to which they are identified as: a) solidifieds for use in further processing purposes in industry; b) solidified as processing products for use in further technological procedures; c) solidified as by-products of technological or physico-chemical processing procedures; d) solidified as final ecological products, which are previously reduced in toxicity, toxicity or harm to nature and the environment; e) solidifieds that represent a material component of further technological procedures, physico-chemical and mechanical treatments, and f) solidifieds for the preparation of utilization in technological processes or for utilization in construction, road construction, or g) for utilization in the field of obtaining technical protective materials for the construction of barriers against the aggressive and harmful effects of other materials (eg radionuclides), etc.
Solidifikati su vrlo često podvrgnuti daljim tehnološkim postupcima ili nekoj drugoj preradbi zbog njihovih neprimjernih, netehničkih i netehnoloških stanja, kao vrlo sitnih praškova, radi njihove zapaljivosti na zraku, higroskopnosti, sadržaja štetnih elemenata iznad maksimalno dopuštenih koncentracija (MDK) itd. Solidifieds are very often subjected to further technological procedures or some other processing due to their inappropriate, non-technical and non-technological conditions, as very fine powders, due to their flammability in air, hygroscopicity, content of harmful elements above the maximum permissible concentrations (MDK), etc.
Najčešće se solidifikati direktno koriste u prahu kao dodaci procesima, zatim pakiraju u tzv. yumbo-vreće (1000 kg) ili pak učvršćuju prešanjem u ploče, blokove i brikete; aglomeriraju ili peletiraju. Most often, solidifieds are directly used in powder form as additions to processes, then packed in so-called yumbo-bags (1000 kg) or solidified by pressing into plates, blocks and briquettes; agglomerate or pelletize.
Neki solidifikati nisu povoljni za aglomeraciju i peletizaciju, a neki kod prešanja na visokim pritiscima (>20 MPa) istiskuju tekuće frakcije (mineralna i druga ulja, vodu i plinovite sadržaje). Some solidifieds are not favorable for agglomeration and pelletization, and some displace liquid fractions (mineral and other oils, water and gaseous contents) when pressed at high pressures (>20 MPa).
Najčešće su takvi istisnuti sadržaji stiješnjenih solidifikata ekološki neprimjereni, te predstavljaju novi tehnički, ekološki i tehnološki problem. Most often, such squeezed contents of compacted solids are ecologically inappropriate, and represent a new technical, ecological and technological problem.
Određene vrste solidifikata, koji nakon stješnjivanja, premda i s vrlo visokim pritiscima i dalje sadržavaju štetne tvari, a kojih se utvrđuje analizom prema poznatom standardu ispitivanja (topljenje u 5%-tnoj otopini octene kiseline, 24 sata intenzivnog miješanja, dužeg odstajavanja i konačnog analiziranja sadržaja eluata). Certain types of solidifieds, which after compaction, even with very high pressures, still contain harmful substances, and which are determined by analysis according to a known test standard (melting in a 5% acetic acid solution, 24 hours of intensive mixing, longer standing and finally analyzing the contents eluate).
Da bi solidifikat, koji se namjerava odlagati npr. na neko odlagalište (prvi ekološki aspekt preradbe tvari i supstancija) imao Što višu stabilnost, a kod analiziranja eluata pokazivao primjereno stanje sukladno propisima o klasifikaciji otpadaka, isti se mora podvrgnuti nekom od postupaka, kojim će se postići poboljšano stanje njegove kakvoće. In order for the solidified, which is intended to be disposed of, for example, in a landfill (the first ecological aspect of the processing of substances and substances) to have the highest possible stability, and when analyzing the eluate to show an appropriate condition in accordance with the regulations on waste classification, it must be subjected to one of the procedures, which will to achieve an improved state of its quality.
Kako se prema kategorizaciji otpadaka, koji se odlažu na komunalne i/ili sanitarne deponije pojavljuju problemi osiguranja načina i mjesta odlaganja, velike razlike u cijeni takvog zbrinjavanja, načina transporta i sl., u tehničko-tehnološkom, ekološkom i ekonomskom smislu, njegova inertizacija, stabilizacija i imobilizacija postaje tim značajnija i važnija od same preradbe tvari i supstancije postupkom solidifikacije. As according to the categorization of waste, which is disposed of in communal and/or sanitary landfills, there are problems of securing the method and place of disposal, large differences in the price of such disposal, methods of transport, etc., in technical-technological, ecological and economic terms, its inertization, stabilization and immobilization becomes all the more significant and important than the processing of substances and substances through the solidification process.
Prema ovom izumu rješava se naznačeni tehnički problem, tako, što solidifikati nastali iz preradbe otpadnih ulja i posebnih otpadaka (ugljikovodika) kao i solidifikati nastali iz preradbe drugih vrsta organskih i neorganskih materijala dobivaju karakteristike stabilnog, inertnog i imobiliziranog materijala, kojega odlaganje na komunalnu deponiju dopušta njegov kemijski sastav, mehanička svojstva i analiza eluata. According to this invention, the indicated technical problem is solved, so that the solidifieds resulting from the processing of waste oils and special waste (hydrocarbons), as well as the solidifieds resulting from the processing of other types of organic and inorganic materials, acquire the characteristics of a stable, inert and immobilized material, which can be disposed of in a municipal landfill allows its chemical composition, mechanical properties and eluate analysis.
U praksi preradbe otpadnih ugljikovodika postupkom solidifikacije posebni tehnički problem predstavlja toplinsko stanje solidifikata pri izlasku iz reaktora, jer sa temperaturama iznad 105°C istog je teško podvrgavati stješnjivanju, dok u obliku praha ima veoma malu brzinu hlađenja na zraku i raspršuje se u okolinu i kod najmanjeg vjetra. In the practice of processing waste hydrocarbons by the solidification process, a special technical problem is the thermal state of the solidified when leaving the reactor, because at temperatures above 105°C it is difficult to subject it to compaction, while in powder form it has a very low rate of cooling in the air and disperses into the environment and at the slightest wind.
Također, ukoliko solidifikati imaju sadržaje hlapivih dijelova ili gorivih tvari, one će sitnim plavičastim plamenom sagorijevati u nakupini i po nekoliko dana. Also, if the solidifieds contain volatile parts or combustible substances, they will burn in a cluster with a small bluish flame for several days at a time.
Stanje tehnike State of the art
Autoru ovog izuma poznato je, da se u svijetu nastojalo postići učvršćivanje solidifikata pomoću pepela elektrofiltera, miješanje sa slamom, glinom ili injektorima sa silikatnim vrstama tekućih tvari. The author of this invention is aware that efforts have been made to solidify the solidified by means of electrofilter ash, mixing it with straw, clay or injectors with silicate types of liquid substances.
Neki drugi postupci inertizacje, neutralizacije i imobilizacije solidifikata, autoru ovog izuma, u trenutku ove prijave, nisu poznati. Some other procedures of inertization, neutralization and immobilization of solidified are not known to the author of this invention at the time of this application.
U rafinerijama nafte i ulja, kod postupaka rafinacija i derivacija nafte i pri tome nastajanja raznih otpadnih ulja, gudrona, uljnog gača, katransko-mazutnih i drugih taloga i muljeva, uljevina i sl. isti se uglavnom odlažu u velike tankvane, lagune (zemljane površine sa glinenom podlogom, odnosno tzv. "crne jame"), betonske bazene ili čelične tankove i cisterne, te se ostavljaju takvima (najčešće na otvorenom), gdje se nakon dužih vremenskih razdoblja donji dijelovi smjese taloženjem teških frakcija učvršćuju sami od sebe, bitumeniziraju i tako tvore čvrste homogene slojeve na dnu. Takav način učvršćivanja nije povoljno ekološko rješenje i takav materijal je i nadalje rizičan i ekološki neprimjeren za prirodu i okoliš, te se ne može transportirati, dalje industrijski iskorištavati, spaljivati, niti odlagati na deponije. In oil and oil refineries, in the process of refining and derivation of oil and in the process of the formation of various waste oils, tar, oil sludge, tar and fuel oil and other sediments and sludges, oily substances, etc., they are mostly disposed of in large tank tanks, lagoons (ground surfaces with a clay substrate, i.e. so-called "black pits"), concrete pools or steel tanks and cisterns, and are left as such (most often in the open), where after longer periods of time, the lower parts of the mixture solidify by themselves due to the precipitation of heavy fractions, bituminize and thus forming solid homogeneous layers at the bottom. Such a method of strengthening is not a favorable ecological solution, and such material is still risky and ecologically inappropriate for nature and the environment, and cannot be transported, further industrially exploited, incinerated, or disposed of in landfills.
Odlaganje takvih materijala u standardne limene bačve uobičajenog volumena od oko 200 litara rezultira korozivnim raspadom lima bačava i curenje opasnog materijala u prirodu i okoliš. The disposal of such materials in standard tin barrels with a usual volume of about 200 liters results in the corrosive disintegration of the tin barrels and the leakage of dangerous material into nature and the environment.
Preporuke sa injektiranjem nekih vrsta tekućih silikata u solidifikate (ili u tijeku samog postupka solidifikacije materijala) pokazalo se nedovoljno sigurnim, skupim i tehnološki kompliciranim postupkom, koji nije naišao na veću primjenu, niti koju bi autor ovog izuma bilo gdje zamijetio kao usvojeno praktično rješenje. Recommendations with the injection of some types of liquid silicates into solidifieds (or during the material solidification process itself) turned out to be an insufficiently safe, expensive and technologically complicated process, which did not find widespread use, nor would the author of this invention have noticed anywhere as an adopted practical solution.
Miješanje sa slamom, glinom, zemljom i pepelima elektrofiltera neprimjereni je način ekološkog rješavanja, jer je takav oblik ne samo zadržao postojeće stanje, već i dodatno onečistio osnovni materijal i doveo do novih oblika zagađivanja okoliša. Mixing with straw, clay, earth and ashes of electrofilters is an inappropriate way of ecological solution, because such a form not only maintained the existing condition, but also additionally polluted the basic material and led to new forms of environmental pollution.
Spaljivanje takvih materijala nije dobilo povoljno uporište u zakonodavstvu i propisima o otpadu, a prijedlog kojim se istog preporučivalo za cementare, ciglane i toplane već je ranije utvrđen kao neprihvatljiv, pa se stoga spaljivanje ne nalazi u širokoj primjeni. Incineration of such materials did not gain a favorable foothold in the legislation and regulations on waste, and the proposal recommending it for cement plants, brick factories and heating plants was previously determined to be unacceptable, and therefore incineration is not widely used.
Tehnologija učvršćivanja pomoću zemlje i gline (tzv. "GSF"-postupak, ili postupak po Bölsingu i drugi), u kojem su se postupku solidifikacije koristile neke teške masne kiseline (oleinska, stearinska), ili zatim, takva smjesa miješala sa glinom i zemljom, stvarala je ogromne količine materijala kojima se nije našao način sigurnog odlaganja, pa takvi još i danas stoje na mnogim mjestima unutar rafinerija ulja i nafte, petrokemijskih industrija i pogonima distribucije produkata derivata nafte zauzimajući velike površine i ozbiljnije volumene privrednih ili prirodnih prostora. The technology of solidification using earth and clay (the so-called "GSF"-process, or the process according to Bölsing and others), in which some heavy fatty acids (oleic, stearic) were used in the solidification process, or such a mixture was mixed with clay and earth , created huge amounts of materials that could not be safely disposed of, so they are still standing today in many places inside oil and petroleum refineries, petrochemical industries and oil derivative product distribution facilities, occupying large areas and significant volumes of commercial or natural spaces.
Kod takvog konačnog učvršćivanja produkata solidifikacije nastao učvršćeni materijal ne može se dalje iskorištavati, a njegovo zbrinjavanje dopušteno je samo na sanitarna odlagališta, što opet predstavlja ekološki problemi iziskuje enormno visoku djenu za ponovno potrebite sanacije terena. With such final solidification of solidification products, the resulting solidified material cannot be used further, and its disposal is allowed only in sanitary landfills, which again presents environmental problems and requires an enormously high cost for the necessary rehabilitation of the terrain.
Solidifikati su se najčešće ostavljali na otvorenim prostorima gdje su se uz jače vjetrove raspršivali u okoliš, a s vremenom otvrdnjavali sami po sebi, tvoreći čvrstu gornju koru. Volumeni tako zauzetih površina obično su veoma veliki. Solidifieds were most often left in open spaces, where they were dispersed into the environment by strong winds, and over time hardened by themselves, forming a solid upper crust. The volumes of such occupied surfaces are usually very large.
Nasipavanjem većih količina zemlje na solidifikate (npr. "Cedre", Brest, Francuska) obavljalo se ozelenjavanje takvih površina, obično zatravnjenjem otpornijim vrstama trava, a što se pokazalo mogućim, ali ne i dovoljno sigurnim za zaštitu prirode i okoliša. By pouring large amounts of soil on solidifieds (eg "Cedre", Brest, France), such areas were greened, usually by grassing with more resistant types of grass, which turned out to be possible, but not safe enough for the protection of nature and the environment.
Koliko je autoru ovog izuma poznato, primjena bilo koje u praksi usvojene tehnologije postupka inertizacije, imobilizacije i stabilizacije solidifikata na ekološko-ekonomski i tehničko-tehnološki način ne nalazi se u današnjem stanju tehnike. As far as the author of this invention is aware, the application of any technology adopted in practice for the process of inertization, immobilization and stabilization of solidified in an ecological-economical and technical-technological way is not found in the current state of the art.
Izlaganje suštine izuma Presentation of the essence of the invention
Solidifikacija tvari i supstancija je proces kojim se uobičajeno nazivaju postupci kod kojih se tekućine ukrućuju, pa tako postaju suhi produkti procesa. Solidification of substances and substances is a process commonly referred to as procedures in which liquids solidify, thus becoming dry products of the process.
Solidifikacija, prema ovom izumu je proces, kod kojeg se bilo tekućina, bilo krutina ili neko drugo agregatno međustanje ulaznog materijala pretvara u potpuno suho stanje isparava-njem vode, koje na izlasku iz reaktora joŠ uvijek ima temperaturu procesa s kojom je i promjena nastala. Solidification, according to this invention, is a process in which either a liquid, a solid, or some other aggregated intermediate state of the input material is transformed into a completely dry state by evaporation of water, which, on exiting the reactor, still has the process temperature at which the change occurred.
Dodavanje vezujućih sredstava takvom solidifikatu u cilju prešanja povezano je sa problemom temperaturnih razlika, pa se dodaci kao što su slama, vlakna tekstila, juta ili slične strukture pale, gore i konačno nestaju u solidifikatu, koji se nakon toga opet vraća u prah. Adding binders to such a solidified for the purpose of pressing is related to the problem of temperature differences, so additives such as straw, textile fibers, jute or similar structures fall, burn and finally disappear in the solidified, which then returns to powder.
Solidifikatima se temeperatura nakon njegova stvaranja i po izlasku iz reaktora teško ili vrlo teško snizuje na zraku (28 - 48°C dnevno), pa se pojavljuje problem vrlo dugih vremenskih razlika od vremena izlaska solidifikata do dolaska u temperaturu okoline na kojoj se prešanje solidifikata može uspješno obavljati. Kako se solidifikati međusobno razlikuju po svojim svojstvima, a u ovisnosti o tome iz kakvih je materijala stvoren i o načinu vođenja procesa solidifikacije, ovom prijavom će se opisati postupci njegove inertizacije, imobilizacije i stabilizacije. The temperature of solidifieds after its creation and after leaving the reactor is difficult or very difficult to lower in the air (28 - 48°C per day), so there is a problem of very long time differences from the time of leaving the solidified to reaching the ambient temperature at which the pressing of the solidified can be done. perform successfully. Since solidifieds differ from each other in terms of their properties, depending on the materials they are made of and the way the solidification process is conducted, this application will describe the procedures for its inertization, immobilization and stabilization.
Solidifikati nastali preradbom otpadnih ulja i posebnih otpadaka (ugljikovodika), a koji su već ranije prijavljeni Državnom zavodu za intelektualno vlasništvo Republike Hrvatske, prijavama istog autora i to: P 940323 N (P 1279/86) P 940326 (P 578/90), P 940325 (P 2123/87.), P 940324 (P 950/88.), P 970498, P 970177 A, P 980049 A, P 970530 A i P 931506 imaju karakteristiku suhog i sitnog hidrofobnog praha izlazne temperature iz procesa na razini 105 - 130°C. Solidifieds resulting from the processing of waste oils and special waste (hydrocarbons), which have already been previously reported to the State Institute for Intellectual Property of the Republic of Croatia, in applications by the same author, namely: P 940323 N (P 1279/86) P 940326 (P 578/90), P 940325 (P 2123/87), P 940324 (P 950/88), P 970498, P 970177 A, P 980049 A, P 970530 A and P 931506 have the characteristic of a dry and fine hydrophobic powder at the exit temperature from the process 105 - 130°C.
Zadržana unutarnja kalorična vrijednost solidifikata (od 5 do >20 MJ/kg) odražava se njegovom visokom toplinom i temperaturom stajanja u relativno dugom vremenskom razdoblju (3-5 dana), iako solidifikat ne gori. The retained internal calorific value of the solidified (from 5 to >20 MJ/kg) is reflected by its high heat and standing temperature for a relatively long period of time (3-5 days), although the solidified does not burn.
Tehničkim rješenjem po ovoj prijavi, takav solidifikat, a zbog odličnih svojstava koje ga obilježavaju nakon izlaska iz reaktora, i sa svojom visokom temperaturom izlaska iz procesa, propušta se kroz tunel na trakastom transporteru, gdje se hladi u struji zraka, rasprskajućom hladnom vodenom maglicom, pa kad solidifikat poprimi temperaturu od oko 55°C nakon izvršenog postupka solidifikacije tada se jednoliko raspršuje i granulat, koji je po svom sastavu smjesa usitnjenog stakla i kvarcnog pijeska, uglavnom niske i srednje granulacije. With the technical solution according to this application, such a solidified, and due to its excellent properties after leaving the reactor, and with its high exit temperature from the process, is passed through a tunnel on a belt conveyor, where it is cooled in the air stream, by spraying cold water mist, so when the solidified reaches a temperature of about 55°C after the solidification process is completed, then the granulate, which by its composition is a mixture of crushed glass and quartz sand, is dispersed uniformly.
Nakon izlaska iz tunela, dužine, koja zavisi od kapaciteta obradbe, takav solidifikat se pothlađuje približno na vanjsku temperaturu i podvrgava prešanju u blokove ili brikete. After exiting the tunnel, the length of which depends on the processing capacity, such solidified is cooled to approximately outside temperature and subjected to pressing into blocks or briquettes.
Njegova zadržana unutarnja kalorična toplina troši se na apsorpciju dodanog granulata te konačno stabilizira u čvrsti komadni blok, koji se više ne raspada kod pretovara, niti pri padu na čvrsto tlo ili pak nabijanja jednog na drugi. Its retained internal caloric heat is spent on the absorption of the added granulate and finally stabilizes into a solid piece block, which no longer disintegrates during handling, nor when falling on solid ground or being rammed one on top of another.
Nakon nekoliko dana takav blok pokazuje vrlo visoku čvrstoću i tvrdoću, te gotovo u potpunosti inertizira i imobilizira svoj sadržaj. After a few days, such a block shows very high strength and hardness, and almost completely inerts and immobilizes its contents.
Poradi boljeg objašnjenja načina provedbe postupka učvršćivanja i suštine nastajanja stabilnosti strukture solidifikata, koji se nakon toga obnaša visokootporno na udar i habanje, stječe bolju sposobnost stješnjivanja i inertizacije, pri čemu se znatno povećava stupanj njegove čistoće sadržaja kod analiziranja kakvoće eluata, u daljem će se opisu detaljnije obrazložiti. In order to better explain the method of implementation of the hardening procedure and the essence of the formation of the stability of the structure of the solidified, which after that behaves highly resistant to impact and wear, acquires a better ability to compact and inertize, while the degree of purity of its content increases significantly when analyzing the quality of the eluate, in the future explain in more detail in the description.
Kod daljeg iskorištavanja ovog solidifikata u svrhu proizvodnje hidrofobnih ploča i blokova (vrtne podloge, šumske i staze parkova i trgova, ploče i pločice za izolaciju terena, pokrivala, prekrivala i slično), u smjesu spomenutog granulata ugrađuju se različita metalna i druga vlakna za mehaničko povezivanje solidifikata. In the further use of this solidified for the purpose of producing hydrophobic plates and blocks (garden substrates, forest and paths of parks and squares, plates and tiles for field insulation, coverings, coverings and the like), various metal and other fibers for mechanical connecting the solidified.
Poradi iskorištavanja solidifikata u svrhu izrade specijalnih vodootpornih ploča ili izgradnje tehničkih barijera u svrhu zaštite od utjecaja otrovnih, toksičnih, opasnih i radioaktivnih materijala, granulat koji pored usitnjenog stakla i kvarcnog pijeska sadrži i praškove, niti i vlakna, dograđuje se i strugotinama teških metala, kao što su: olovo, Pb; krom Cr; Željezo, Fe; Mangan, Mn; Volfram, W; Vanadij, V; Nikal, Ni i dr. Due to the use of solidified for the purpose of making special waterproof boards or building technical barriers for the purpose of protection against the effects of poisonous, toxic, dangerous and radioactive materials, granulate, which contains powders, threads and fibers in addition to crushed glass and quartz sand, is also supplemented with heavy metal shavings, such as: lead, Pb; chromium Cr; Iron, Fe; Manganese, Mn; Wolfram, W; Vanadium, V; Nikal, Ni et al.
Kod solidifikata koji su stvoreni od organskih muljeva (muljevi pročistača otpadnih voda, uljevina, kaljužna zauljena voda, zauljena zemlja i blato) dodavanju granulata na bazi stakla i kvarcnih pijeskova pridružuje se polusuha cementna smjesa, koja se pomoću raspršivanja suhog cementa u vodenoj magli podjednako nanosi na površinu solidifikata koji se kreće po trakastom transporteru u zatvorenom tunelu. In the case of solidifieds created from organic sludge (sludge from wastewater treatment plants, oil sludge, oily bilge water, oily soil and mud), semi-dry cement mixture is added to the addition of granulates based on glass and quartz sand, which is evenly applied by spraying dry cement in a water mist. on the surface of solidified moving on a belt conveyor in a closed tunnel.
Solidifikatima koji su nastali preradbom organskih vrsta otpadaka iz sastava posebnog otpada, a kojih ne karakterizira visoka temperatura izlaznog solidifikata, već vrlo visoka temperatura solidifikata u nakupini (poradi kasnijeg specifičnog izgaranja njegovog izmiješanog sadržaja tvari, koje gore na temperaturama iznad 120°C) njemu se dodavaju povećani sadržaji staklenih granulata i kvarcnog pijeska veće granulacije. Solidifieds that were created by the processing of organic types of waste from the composition of special waste, and which are not characterized by a high temperature of the outgoing solidified, but rather a very high temperature of the solidified in the accumulation (due to the subsequent specific combustion of its mixed content of substances, which burn at temperatures above 120°C) they add increased contents of glass granules and quartz sand of higher granulation.
Solidifikatima koji su nastali iz obradbe zemljanih masa onečišćenih pesticidima (DDT, fungicidi, herbicidi, organski fosfori i karbaimidi, klorirani ugljikovodici, akaricidi, nematocidi, rodenticidi, limacidi) pored kvarcnih pijeskova dodavaju se i prirodni šljunkovi radi dobivanja geo-kompozita visoke čvrstoće nabijanja. In addition to quartz sand, natural gravel is added to the solidifieds resulting from the processing of soil masses contaminated with pesticides (DDT, fungicides, herbicides, organic phosphorus and carbaimides, chlorinated hydrocarbons, acaricides, nematocides, rodenticides, limacides) in order to obtain a geo-composite with high compaction strength.
Svrha ovakvih dodataka je izgradnja stabilne strukture smjese solidifikata u kojoj se ostvaruje proces apsorpcije i oduzimanje topline, stvaranje silikatnih kora u čitavom presjeku prešanog bloka, te dobivanje njegove čvrstoće i tvrdoće sa žilavom jezgrom. The purpose of such additives is to build a stable structure of the solidified mixture in which the process of absorption and removal of heat is realized, the formation of silicate crusts in the entire cross-section of the pressed block, and obtaining its strength and hardness with a tough core.
Unutarnjja toplina solidifikata veže preostali kalcij, koji je, kod dobivanja solidifikata po ovom izumu uvijek u suvišku na dodavani granulat, tvoreći kompleksne silikatno kalcijeve spojeve, koji imaju viši stupanj stabilnosti od čistog solidifikata i koji zatim aktivno sudjeluju u procesu do potpune polimerizacije ukupnog sadržaja. The internal heat of the solidified binds the remaining calcium, which, when obtaining the solidified according to this invention, is always in excess of the added granulate, forming complex silicate-calcium compounds, which have a higher degree of stability than the pure solidified and which then actively participate in the process until the complete polymerization of the total content.
U slijedu procesa polimerizacije, a koji direktno utječe na ostvarivanje uvjeta inertizacije sastava cijelog stiješnjenog bloka, postignut je cilj, za kojeg se po ovoj prijavi i traži patentna zaštita. In the sequence of the polymerization process, which directly affects the realization of the conditions of inertization of the composition of the entire compacted block, the goal was achieved, for which patent protection is requested according to this application.

Da bi se isti rashladio na oko 55°C provodi se kroz tunelski kanal 8 iznad kojeg je smješten nadsvod sa dvostrukim plaštom 6 kroz kojega struji hladna voda kao izmjenjivač topline. Dozatorski sustav dodataka koji utječu na poliinerizaciju solidifikata snabdjeven je komorama A, B, C, D i E iz kojih se ovi dodaci propuštaju na solidifikat. Prešom 12 takva se srnjesa stješnjuje u blokove, a zatim se oni odvode trakastim transporterom 14 u kontejner za otpremu ili skladištenje. Figure 1 shows the path of solidified 2 from the processing reactor 4, which falls on the belt conveyor 10 as hot powder. In order to cool it down to about 55°C, it is passed through a tunnel channel 8, above which is placed a double-clad overhang 6, through which cold water flows as a heat exchanger. The dosing system of additives that affect the polyinerization of the solidified is supplied with chambers A, B, C, D and E from which these additives are passed onto the solidified. With a press 12, such roe is compacted into blocks, and then they are taken by belt conveyor 14 into a container for shipping or storage.
Presjek nad tunelskim prostorom prikazan je na Slici 2. gdje se solidifikat 2 kreće kroz tunelski kanal 8 trakastim transporterom 10, a u komorama A/ B, C, D i E nalaze dodaci za polimerizaciju. Otvaranjem zapornih ventila u dvostrukom plaštu 6 tunela 8, što se obavlja automatskim upravljanjem sa komandnog uređaja, određuje se brzina i količina dodavanja pojedinih vrsta dodataka, dok se izvod vodene pare obavlja usisnim pumpama na otvorima 20. The section above the tunnel space is shown in Figure 2, where the solidified 2 moves through the tunnel channel 8 by belt conveyor 10, and in chambers A/B, C, D and E there are additions for polymerization. By opening the shut-off valves in the double shell 6 of the tunnel 8, which is performed by automatic control from the control device, the speed and quantity of adding certain types of additives is determined, while the extraction of water vapor is performed by suction pumps at the openings 20.
Na Slikama 3, 4, 5, 6 i 7. prikazani su neki od uobičajenih oblika otpresaka kojih je moguće dobiti od pothlađenog solidifikata uz odgovarajuća vezivna sredstva, a prema mogućem izboru snage pritiska preše. Figures 3, 4, 5, 6 and 7 show some of the usual forms of press that can be obtained from the cooled solidified with appropriate binders, and according to the possible choice of press pressure.
Povoljni pritisci se kreću od 5 do 15 Mpa. Favorable pressures range from 5 to 15 Mpa.
Tako je moguće formirati ravne ploče prema Slici 3. odnosno, stvarati pojedine slojeve kod polaganja hidroizolacijskog tepiha na tlu. Takvi slojevi mogu iznositi od ≈ 200 mm pa sve do 1.000 mm debljine pri čemu je postignuta vodonepropusnost na razini < 2-10-9 m/s. Deblje ploče, prema Slici 4. formiraju se ugradnjom mrežastih armatura 24 i njihove dimenzije mogu biti i preko 500 x 500 x 1000 mm. Thus, it is possible to form flat panels according to Figure 3, that is, to create individual layers when laying the waterproofing carpet on the ground. Such layers can be from ≈ 200 mm up to 1,000 mm thick, where watertightness is achieved at the level of < 2-10-9 m/s. Thicker panels, according to Figure 4, are formed by installing mesh reinforcements 24 and their dimensions can be over 500 x 500 x 1000 mm.
Valjkasti briketi, prema Slici 5. Mogu se prešati u dimenzijama od ø 60 x 30 mm do ø 600 x 150 mm, a uz ugradnju armaturne mrežice i preko tih dimenzija. Roller briquettes, according to Figure 5. They can be pressed in dimensions from ø 60 x 30 mm to ø 600 x 150 mm, and with the installation of a reinforcing mesh, they can also be pressed beyond these dimensions.
Kvadratni blokovi većih dimenzija, prema Slici 6. nalikuju standardnim vrstama npr. Kao kod betonskih blokova (400 x 300 x 200 mm), koji se mogu prešati sa ili bez armature 26, dok uz jače mrežaste armature ovi blokovi mogu imati dimenzije i preko 1000x1000 x 1000 mm Square blocks of larger dimensions, according to Figure 6, resemble standard types, for example, as with concrete blocks (400 x 300 x 200 mm), which can be pressed with or without reinforcement 26, while with stronger mesh reinforcement these blocks can have dimensions of over 1000x1000 x 1000 mm
Fazonski komadi, djevi i profili, prema Slici 7. obično ovise o kalupima u kojima se formiraju i kod kojih se mogu proizvesti dovoljni pritisci preša, pa se cijevi mogu proizvoditi od Ø 100 do Ø 1000 mm, pa i više, a duljina takvih profila ovisiti će o kalupima, broju, kakvoći i vrstama mrežastih armatura. Shaped pieces, blanks and profiles, according to Figure 7, usually depend on the molds in which they are formed and where sufficient press pressures can be produced, so pipes can be produced from Ø 100 to Ø 1000 mm, and even more, and the length of such profiles it will depend on the moulds, number, quality and types of mesh reinforcements.
Detaljan opis najmanje jednog od načina ostvarivanja izuma A detailed description of at least one way of realizing the invention
U slijedećem će se opisu do u potpunosti objasniti svaka pojedinost ostvarivanja izuma, čega je jedan primjer ilustriran pridruženim crtežima. In the following description, every detail of the realization of the invention will be fully explained, one example of which is illustrated by the accompanying drawings.
Temeljem uvida u sliku 1. i 2. objašnjen je način hlađenja solidifikata u prisilnoj struji hladnoga zraka, a kojeg ostvaruje kompresor-ventilator sa perforirane stijene 22 pokrivala trakastog transportera. Based on the insight into pictures 1 and 2, the method of cooling the solidified in a forced stream of cold air, which is achieved by the compressor-fan from the perforated wall 22 of the cover of the belt conveyor, is explained.
Prema ovoj patentnoj prijavi koristi se pothlađivač sa recirkulirajućom vodom, iz bazena, kao trajnog izmjenjivača topline. Bazen se također prema potrebi, naročito kod dugotrajnog pogona, stalno izmjenjuje protočnom hladnom vodom iz bilo kojeg izvora. According to this patent application, a subcooler with recirculating water from the pool is used as a permanent heat exchanger. The pool is also constantly replaced with running cold water from any source as needed, especially during long-term operation.
Pomoću većeg broja otvora 22 koji se nalaze u donjem dijelu nadsvoda sa dvostrukim plaštom 6 iznad prekrivala trakastog transportera 10, u struji zraka propuštaju se dodaci A, B, C, D i E namijenjeni jednolikom miješanju sa solidifikatom 2, koji se kreće na traci transportera 10. By means of a large number of openings 22 located in the lower part of the arch with a double jacket 6 above the cover of the belt conveyor 10, additives A, B, C, D and E intended for uniform mixing with the solidified 2, which moves on the conveyor belt, are passed in the air stream 10.
Debljina sloja solidifikata 2 na transporteru 10 ovisi o kapacitetu obrade i širini trake Najpovoljnija debljina sloja solidifikata na traci je oko 5-6 mm, ali najviše 10 - 12 mm, a što se podešava pravilnim dimenzioniranjem širine trake i brzine kretanja, pa će tako za kapacitete obradbe < 5 m3/h biti povoljan onaj trakasti transporter čija je širina trake oko 500 mm, a brzina njegova kretanja oko 1 m/ s. The thickness of the solidified layer 2 on the conveyor 10 depends on the processing capacity and the width of the belt. The most favorable thickness of the solidified layer on the belt is about 5-6 mm, but at most 10 - 12 mm, which is adjusted by properly dimensioning the width of the belt and the speed of movement, so for for processing capacities < 5 m3/h, the belt conveyor with a belt width of about 500 mm and a speed of its movement of about 1 m/s should be advantageous.
Kod kapaciteta obradbe od 15-20 m3/h takav trakasti transporter mora imati širinu od oko 700 mm i brzinu kretanja oko 2 - 4 m/ s. With a processing capacity of 15-20 m3/h, such a belt conveyor must have a width of about 700 mm and a movement speed of about 2 - 4 m/s.
Vrlo veliki kapaciteti obradbe npr. oko ili > 50 m3/h solidifikata zahtijevaju posebne konstrukcije tunela sa trakastim transporterom, pa iz ekonomskih razloga najbolje je tada ovu količinu solidifikata rasporediti u dvije izlazne trake po 25 m3/h i na dva tunela jednake dužine. Very large processing capacities, for example around or > 50 m3/h of solidified, require special tunnel constructions with a belt conveyor, so for economic reasons it is best to distribute this amount of solidified in two output lanes of 25 m3/h each and in two tunnels of equal length.
Količina dodataka A, B, C, D i E je varijabilna i ovisi o mnogim čimbenicima kao što su: vrsta materijala obrade od kojeg je stvoren solidifikat, izlazna temperatura solidifikata, brzina hlađenja solidifikata, svrha u koju će se solidifikat odnosno njegov prešani oblik konačno koristiti itd. The amount of additives A, B, C, D and E is variable and depends on many factors such as: the type of processing material from which the solidified was created, the exit temperature of the solidified, the cooling rate of the solidified, the purpose for which the solidified or its pressed form will be finally use etc.
Za prosječnu vrstu materijala obradbe koji imaju ugljikovodike i čiji je sadržaj na razini 20 - 30 vol % ili veći od 30 vol %, a manji od 40 vol %, te sa ciljem dobivanja solidifikata koji će biti kao inertni materijal odložen na komunalnu deponiju, sadržaji dodataka za dobru inertizaciju iznose: For the average type of processing materials that have hydrocarbons and whose content is at the level of 20 - 30 vol % or greater than 30 vol % and less than 40 vol %, and with the aim of obtaining a solidified which will be disposed of as an inert material at a municipal landfill, the contents additives for good inertization amount to:
- 2 min dodataka na svakih 6 mm debljine solidifikata po širini trake, a što je za traku bilo koje širine dodatak sa udjelom od 33 vol %. - 2 min of additions for every 6 mm of solidified thickness across the width of the strip, which for a strip of any width is an addition with a proportion of 33 vol %.
Jednolikim raspoređivanjem dodataka s udjelom od 33 vol % isti se raspodjeljuje prema odnosu: oko 65vol% dodataka od usitnjenog stakla i oko 35vol% kvarcnog pijeska. By uniformly distributing additives with a share of 33 vol%, it is distributed according to the ratio: about 65vol% of crushed glass additives and about 35vol% of quartz sand.
Vodena maglica će se stvarati kondenzacijom pothlađivanja zraka u struji s vodenom parom koju otpušta solidifikat, pa s dodacima podjednako rasprostranjivati po širini trake. The water mist will be created by the condensation of subcooling air in the stream with water vapor released by the solidified, and then spread equally along the width of the strip with additives.
Kod dobivanja solidifikata kojega će se, nakon stješnjivanja, uporaba naći u smislu hidroizolacijskog sredstva (hidro ploče i blokovi) isti je najbolje podvrgnuti što boljem hlađenju i dodavan)u oko 30 vol % udjela kvarcnog pijeska, oko 30 vol % usitnjenog stakla, oko 30 vol % granulata tvrđeg vezivnog sredstva i oko 10 vol% cementnog praha. When obtaining a solidified which, after compaction, will be used as a waterproofing agent (hydro panels and blocks), it is best to subject it to as good cooling as possible and add) about 30 vol % of quartz sand, about 30 vol % of crushed glass, about 30 vol % of hard binder granules and about 10 vol % of cement powder.
Kao vezivo za ojačanje ploča većih dimenzija poželjno je u prešu smještati mrežastu armaturu ili slične dugačke vezivne niti, koje imaju potrebnu otpornost na stvarnim temperaturama solidifikata kod prešanja. As a binder for reinforcing larger panels, it is preferable to place mesh reinforcement or similar long binder threads in the press, which have the necessary resistance at the actual solidification temperatures during pressing.
Kod solidifikata koji su nastali iz obradbe različitih tvari sa sadržajima oksida teških metala (npr. pepeo incineratora ili metalna strugotina i brusna prašina sa emulzijama), i to naročito kada se prešani solidifikat namjerava koristiti u svrhu izgradnje zaštitnih tehničkih barijera protiv utjecaja otrovnih, opasnih, toksičnih i radioaktivnih materijala, takav solidifikat se hladi na temperaturu <55°C u vodenoj maglici sa prisilnim strujanjem hladnog zraka i pri tome mu se dodaje metalna prašina sa sadržajima olova, mangana, kroma, cinka, željeza i sl., te konačno stješnjuje u brikete (npr. Ø 60 x 30 mm). In the case of solidifieds resulting from the processing of various substances containing heavy metal oxides (e.g. incinerator ash or metal shavings and grinding dust with emulsions), especially when the pressed solidified is intended to be used for the purpose of building protective technical barriers against the effects of toxic, dangerous, toxic and radioactive materials, such a solidified is cooled to a temperature of <55°C in a water mist with a forced flow of cold air, and metal dust containing lead, manganese, chromium, zinc, iron, etc. is added to it, and finally compacted into briquettes (eg Ø 60 x 30 mm).
Pritisci preše za briketiranje solidifikata kreću se između 5 i 15 MPa, s time da se manji pritisci koriste za one solidifikate koji će kasnije biti korišteni tako što će se gnječiti ili usitnjavati, a veći pritisci kod solidifikata, koji će se koristiti kao ploče ili blokovi. Press pressures for briquetting solidifieds range between 5 and 15 MPa, with lower pressures being used for solidifieds that will later be used by kneading or shredding, and higher pressures for solidifieds that will be used as slabs or blocks. .
Dužina tunela 8 u kojem se kreće i hladi solidifikat iz reaktora, dimenzionira se prema temperaturi solidifikata i količini vodene pare koja će se otpuštati iz solidifikata na trakastom transporteru 10. The length of the tunnel 8, in which the solidified from the reactor moves and cools, is dimensioned according to the temperature of the solidified and the amount of water vapor that will be released from the solidified on the belt conveyor 10.
Najbolje je koristiti tunele koji imaju što veću visinu, a najmanje oko 450 mm od razine trake. It is best to use tunnels that have as much height as possible, and at least about 450 mm from the lane level.
Kod kapaciteta obrade od oko ili < 5 m3 /h najbolji rezultati inertizacje, imobilizacije i stabilizacije solidifikata postižu se kod tunela čija visina iznosi oko 500 - 600 mm, a kod kapaciteta od oko ili >25 m3/h optimalna visina tunela iznosi od oko ili >1000 mm. With a processing capacity of about or < 5 m3/h, the best results of inertization, immobilization and stabilization of solids are achieved with tunnels whose height is about 500 - 600 mm, and with a capacity of about or >25 m3/h, the optimal tunnel height is about or >1000 mm.
Način primjene izuma Method of application of the invention
Ovaj izum, a koji se koristi za hlađenje solidifikata, nastalog iz obrade različitih vrsta otpadnih materijala u kojima se nalazi i ugljikovodik, te provedba njegove inertizacije, imobilizacije i stabilizacije, primjenjuje se prema u ovoj prijavi prikazanom tehničko-tehnološkom rješenju. This invention, which is used for cooling the solidified, resulting from the processing of various types of waste materials containing hydrocarbons, and the implementation of its inertization, immobilization and stabilization, is applied according to the technical-technological solution presented in this application.
Predloženi način primjene ovog izuma i tehničko rješenje kojim će se postići inertizacija, imobilizacija i stabilizacija solidifikata svedeno je na dodavanje određenih dodataka i smjese dodataka, koje se sastoje od usitnjenog stakla, kvarcnog pijeska, raznih vlakana, prašine opeke, praškova oksida teških metala, cementnog praha, armaturnih vlakana i sličnih vezivnih materijala u uvjetima stvaranja vodene maglice u jednakomjernom nanošenju na solidifikat, koji se kreće po transportnoj traci i koji se hladi u prisilnom strujanju zraka izmjenjivačem u recirkulirajućem sustavu protjecanja vode. The proposed method of application of this invention and the technical solution that will achieve inertization, immobilization and stabilization of the solidified is reduced to the addition of certain additives and a mixture of additives, which consist of crushed glass, quartz sand, various fibers, brick dust, heavy metal oxide powders, cement powder, reinforcing fibers and similar binding materials under the conditions of creating a water mist in an even application to the solidified, which moves along the conveyor belt and which is cooled in the forced air flow by the exchanger in the recirculating water flow system.
Tabličnim će se prikazom pokazati preporučeni sadržaji dodataka i uvjeti u kojima će doći do najboljih rezultata inertizacije, imobilizacije, stabilizacije i polimerizacije pojedinih vrsta solidifikata. The tabular representation will show the recommended content of additives and the conditions in which the best results of inertization, immobilization, stabilization and polymerization of certain types of solidified will be achieved.

Tablica 1. Table 1.
Ukoliko se događa da otpresci nakon nekog vremena sušenja postaju rastresiti, tada je takvoj vrsti solidifikata potrebno mijenjati parametre dodataka u korist vezivnih vrsta i armaturnih vlakana, a posebno odrediti primjereniju silu stješnjivanja. If it happens that after drying for some time the scraps become loose, then for this type of solidified it is necessary to change the parameters of additives in favor of binding types and reinforcing fibers, and in particular to determine a more appropriate compaction force.
Optimalni uvjeti postižu se u tunelu, kada će strujanje biti u uvjetima relativne vlažnosti zraka od oko 77-88%, pri čemu se dodaci ravnomjerno raspoređuju na površinu trake sa solidifikatom, a pritisci stješnjivanja solidifikata odvijaju na razini ≈10 MPa. Optimum conditions are achieved in the tunnel, when the flow will be in conditions of relative air humidity of about 77-88%, whereby the additives are evenly distributed on the surface of the strip with solidified, and the solidified compaction pressures take place at the level of ≈10 MPa.
Ukoliko će se solidifikat otpresivati u ploče većih dimenzija tada je potrebno u prešu postaviti mrežastu armaturu od materijala otpornog na temperaturu pod kojom se nalazi solidifikat (umrežene niti od tvrde gusto prepletene žičane mrežice i sl.). If the solidified is to be pressed into plates of larger dimensions, then it is necessary to place in the press a mesh reinforcement made of material resistant to the temperature at which the solidified is located (networked strands of hard densely woven wire mesh, etc.).
Briketiranje solidifikata na valjkaste manje oblike (npr. Ø 60 x 30 mm) treba koristiti kod solidifikata koji je namijenjen npr. kod izgradnje hidroizolacijskih slojeva u niskogradnji, kojom prilikom će se oni gnječiti na terenu izmiješani sa građevinskim šljunkom, obično ispod razine asfalta ili betona. Takav solidifikat ustvari ne treba imati posebne dodatke ukoliko je njegova kvaliteta visoka i prema analizi ne otpušta ulje niti nema nedopuštenih sadržaja pojedinih elemenata i spojeva, a koji bi nepovoljno utjecali na klasifikaciju eluata (maksimalno dopuštene koncentracije ispitivanih tvari: MDK). U cilju stvaranja što veće inertnosti solidifikata dodaje mu se kvarcni pijesak i usitnjeno staklo u utvrđenom odnosu i definiranoj ukupnoj količini. Kakvoća stakla koje se koristi kod dodavanja u solidifikat nije posebno važna. Staklo može biti bijelo, obojeno ili izmiješano, a granulacija se određuje prema konačnoj svrsi iskorištavanja otpresaka solidifikata. Briquetting of solidified into cylindrical smaller shapes (eg Ø 60 x 30 mm) should be used with solidified which is intended, for example, for the construction of waterproofing layers in civil engineering, in which case they will be crushed on the ground mixed with construction gravel, usually below the level of asphalt or concrete . In fact, such a solidified does not need special additives if its quality is high and, according to the analysis, it does not release oil, nor does it have illegal contents of certain elements and compounds, which would adversely affect the classification of the eluate (maximum permissible concentrations of tested substances: MDK). In order to create the greatest possible inertness of the solidified, quartz sand and crushed glass are added to it in a fixed ratio and a defined total amount. The quality of the glass used when adding to the solidify is not particularly important. The glass can be white, colored or mixed, and the granulation is determined according to the final purpose of utilizing the solidified spray.
Kod većih dimenzija blokova solidifikata povoljnija je veća granulacija stakla (oko 4-15 mm), dok se kod manjih ploča, blokova i briketa koristi niža granulacija, (oko 2-4 mm). Kvarcni pijesak je uobičajeni silikatni pijesak, koji ima različite granulacije, a u praksi se pokazalo da je za miješanje i dobru apsorpciju najpovoljniji onaj s granulacijom 2-3 mm. Niže temperature kod domiješavanja naznačenih dodataka od 55°C nepovoljno djeluju na stvaranje čvrstih kora stvorenih od kalcij-silikatnih spojeva, koji podstiču polimerizaciju i stabilizaciju cjeline strukture zbijenog solidifikata, a one više od 70°C dovode do prebrze apsorpcije i gubitaka efekata domiješavanja, te se raspadaju prilikom hlađenja na zraku i prelaze u početno praškasto stanje. For larger dimensions of solidified blocks, a larger glass granulation (about 4-15 mm) is preferable, while for smaller plates, blocks and briquettes, a lower granulation is used (about 2-4 mm). Quartz sand is the usual silicate sand, which has different granulations, and in practice it has been shown that the one with a granulation of 2-3 mm is the most favorable for mixing and good absorption. Lower temperatures when mixing the indicated additives than 55°C have an unfavorable effect on the formation of hard crusts created from calcium-silicate compounds, which encourage polymerization and stabilization of the entire structure of the compacted solidified, and temperatures above 70°C lead to too fast absorption and loss of mixing effects, and disintegrate during cooling in the air and change to the initial powdery state.
U ovisnosti od sile stješnjivanja solidifikata isti će se brže ili sporije stvrdnjavati ili pak raspadati u prah, pa su najpovoljniji pritisci oni od oko 10 MPa. Kod dobivanja jako hidrofobnih otpresaka taj pritisak može biti i viši, ali maksimalno 15 MPa, jer iznad njega dolazi do tzv. cijeđenja i "znojenja" solidifikata. Depending on the compaction force of the solidified, it will harden faster or slower or crumble into powder, so the most favorable pressures are those of around 10 MPa. When obtaining highly hydrophobic sprays, this pressure can be higher, but a maximum of 15 MPa, because above it the so-called squeezing and "sweating" of the solidified.
Takvi solidifikati su praktično vodonepropusni i imaju koeficijent vodonepropusnosti na nivou 1-10-9 < κ ν < 2-10-9 m/s, a gustoću na nivou 935 < δ< 975 [kg/m3]. Such solidifieds are practically impermeable and have a coefficient of waterproofness at the level of 1-10-9 < κ ν < 2-10-9 m/s, and density at the level of 935 < δ< 975 [kg/m3].
Solidifikati namijenjeni izgradnji tehničkih zaštitnih barijera imaju nekoliko puta višu gustoću: 1124<δ < 1311 [kg/m3], poradi nazočnosti većeg udjela sadržaja teških metala. Solidifieds intended for the construction of technical protective barriers have several times higher density: 1124<δ < 1311 [kg/m3], due to the presence of a higher proportion of heavy metal content.
