Description
Przedmiotem wynalazku jest srodek emulsyjny opóznia¬ jacy wiazanie cementu stosowany w celu uzyskiwania ozdobnych faktur z odslonietego kruszywa na prefabryko¬ wanych elementach betonowych i zelbetowych, szczegól¬ nie formowanych licem od dna formy.Znane sa srodki opózniajace wiazanie cementu jak sole wapniowe kwasów hydroksylokarboksylowych i sacharo¬ za, stosowane w postaci roztworów z wypelniaczami zage¬ szczajacymi w postaci kredy, skrobi i spoiwa, np. deks¬ tryny.Znane srodki opózniajace nie zapewniaja równomiernej penetracji w glab zaprawy cementowej i uzyskania wyraz¬ nej granicy miedzy zwiazana w niezwiazana warstwa za¬ prawy, w wyniku czego uzyskiwane faktury posiadaja niski stopien mrozoodpornosci, co powoduje wypadanie ziarn kruszywa z warstwy faktury pod wplywem zmian atmosferycznych w okresie zimowym. Stosowanie znanych opózniaczy stwarza tez trudnosci w usuwaniu niezwiaza- nej zaprawy nawet sposobem mechanicznym.Ponadto nie mozna przy ich uzyciu wyeliminowac po¬ wstawania filmu cementowego na kruszywie faktury, co pociaga koniecznosc usuwania filmu roztworem kwasu solnego.Istota wynalazku jest wprowadzenie do srodka opóznia¬ jacego wiazanie cementu, opartego o sacharoze, substancji zelujacej w srodowisku wodnym jako nosnika sacharozy oraz substancji tworzacej powloke ochronna przed rozmy- walnoscia.Srodek emulsyjny opózniajacy wiazanie cementu we¬ dlug wynalazku sklada sie z sacharozy, detergentu, srodka ,10 2D antyseptycznego rozpuszczonych w wodzie, nosnika sa¬ charozy, którym jest zelatyna stosowana w ilosci 3-20 % wagowych lub glikolan sodu stosowany w ilosci 5-30 % wagowych, oraz olej lniany sredniowiskozowy w ilosci 5- % wagowych tworzacypowloke ochronna przed rozmy- walnoscia.Srodek opózniajacy stosuje sie do powlekania papieru lub dna formy po czym poddaje sie go wysuszeniu.Stosowanie srodka opózniajacego wedlug wynalazku pozwala na uzyskanie wyraznej granicy miedzy zwiazana i niezwiazana warstwa zaprawy betonowej oraz wysokiej czystosci kruszywa fakturowego. Stosowanie srodka opóz¬ niajacego umozliwia usuwanie niezwiazanej zaprawyprzy pomocy strumienia wody bez koniecznosci czyszczenia mechanicznego dajac w efekcie wysoka czystosc kruszywa i samozmywalnosc faktury w normalnych warunkach at¬ mosferycznych.Przyklad I sacharoza zelatyna (kolagen) olej lniany, srednio-wiskozowy sól sodowa etoksylowanego alkoholu laurylowego srodek antyseptyezny (C(uHl40) woda 36,5 % wagowych 4,5 % wagowych 18,1 % wagowych 0,6 % wagowych 0,3 % wagowych 40,0 % wagowych iipinikjgaeharpzy wiazej^ w taki sposób; ze uniemozli¬ wia jej swobodna dyfuzje w glab zaprawy cementowej, ppza granice, która osiaga sam nosnik. Olej lniany opóznia 88 58488584 proces penetracji nosnika wraz z sacharoza w glab zapra¬ wy betonowej w chwili formowania.Proces penetracji rozpoczyna sie po rozmyciu powloki ochronnej i przebiega przy równoczesnym uwadnianiu sie zelatyny i jej penetracji w glab zaprawy cementowej oraz reakcji zmydlania wolnych kwasów tluszczowych oleju lnianego zawartego pomiedzy czasteczkami zelatyny.Otrzymane w ten sposób mydla dodatkowo zwilzaja powierzchnie kruszywa ulatwiajac zmycie filmu cemento¬ wego z powierzchni faktury.

They are used in the form of solutions with thickening fillers in the form of chalk, starch and a binder, e.g. dextrin. Known retarders do not ensure uniform penetration into the depth of the cement mortar and obtain a clear boundary between the bonded layer. right, as a result of which the obtained textures have a low degree of frost resistance, which causes aggregate grains to fall out of the texture layer under the influence of weather changes in the winter. The use of known retarders also causes difficulties in removing the unbound mortar, even mechanically. Moreover, they cannot eliminate the formation of a cement film on the aggregate texture, which requires the need to remove the film with a hydrochloric acid solution. Binding of cement based on sucrose, a substance that gels in an aqueous environment as a carrier of sucrose and a substance that forms a protective coating against smearing. The emulsion delaying the setting of cement according to the invention consists of sucrose, detergent, a detergent, dissolved in water, a carrier of sucrose, which is gelatine used in the amount of 3-20% by weight or sodium glycolate used in the amount of 5-30% by weight, and medium viscose linseed oil in the amount of 5-30% by weight, which forms a protective film against smudging. coating the paper or the bottom of the mold and dry it The use of the retarder according to the invention allows for a clear boundary between the bonded and the bonded layer of concrete mortar and the high purity of the textured aggregate to be obtained. The use of a retarder allows the removal of unbound mortar with a jet of water without the need for mechanical cleaning resulting in high aggregate purity and self-washing of the texture under normal atmospheric conditions. antiseptic agent (C (uH14) water 36.5 wt.% 4.5 wt.% 18.1 wt.% 0.6 wt.% 0.3 wt.% 40.0 wt. free diffusion into the depth of the cement mortar, crossing the boundary that reaches the carrier itself Linseed oil delays the process of penetration of the carrier together with the sucrose into the depth of the concrete mortar at the time of forming. gelatine and its penetration into the depth of cement mortar and the saponification reaction of free fatty acids of linseed oil contained between gelatine particles. The soaps obtained in this way additionally moisten the aggregate surface, making it easier to wash the cement film from the texture surface. Gelatine partially decomposes in an alkaline environment, releasing gaseous products, e.g. ammonia, which loosen the unbound single layer.
