Description

FOreliggande uppfinning avser ett miljovanligt forfarande att helt avldgsna icke Onskvard nedsmutsning, klottring eller grafitti frAn en yta. The present invention relates to an environmentally friendly process for completely removing non-adverse contamination, graffiti or graffiti from a surface.

Genom att skydda en yta med en film av upplosta animaliska dmnen, som efter torkning är resistent mot organiska losningsmedel, vilket mojliggtir att klotter med tusch sprayfdrger kan som alternativ Aterupplosas och enkelt avldgsnas fran ovanndmnda film med hjalp av organiska losningsmedel utan att skada den nnderliggande originalytan, eller som alternativ offra skyddsfilmen tillsammans med nedsmutsningen genom tvdttning med varmt vatten. By protecting a surface with a film of dissolved animal substances, which after drying is resistant to organic solvents, which makes it possible for graffiti with ink to be redistributed and easily removed from the above-mentioned film with the aid of organic solvents without damaging the underlying original surface. , or alternatively sacrifice the protective film together with the soiling by washing with warm water.

UPPFINNINGENS BAKGRUND. BACKGROUND OF THE INVENTION

PA utsatta offentliga platser är det oftast onskvart att ddr man pA forhand vet eller kan formoda att icke Onskvdrd kontaminering sAsom sot, fett tusch, lack, gummi, fdrger m.m. kan forekomma. Vidare har industrin ofta problem med avsdttningar av fdrg, trycksvdrta eller liknande pi golv, vdggar, kdrl, verktyg m.m. In exposed public places, it is often unfortunate that you know or can assume in advance that undesirable contamination such as soot, grease, ink, varnish, rubber, paints, etc. may occur. Furthermore, the industry often has problems with deposits of paint, printing ink or the like on floors, walls, boilers, tools, etc.

Foreliggande uppf inning har till uppgift att p& ett dadamAlsriktigt och miljdvdnligt sdtt losa ovanstAende problem utan nodvdndigtvis anvAndning av starka organiska eller al-kaliska losningsmedel om man sA Onskar. The object of the present invention is to solve the above problems in a data-correct and environmentally sound manner without necessarily using strong organic or alkaline solvents if desired.

Detta mil uppnAr man genom att behandla den yta som skall skyddas med en animalisk film som efter torktiden har formAgan att Aterupplosas vid behandling med Over °C varmt vatten, ndmnda film fungerar d& som en barridr mellan den yta som skyddats och nedklottringen av t.ex. sprayfdrg eller tusch. This mileage is achieved by treating the surface to be protected with an animal film which after the drying time has the purpose of being redissolved during treatment with Over ° C hot water, the said film then acts as a barrier between the protected surface and the scrapping of e.g. . spray paint or ink.

Detta är mojligt tack vare att den animaliska filmen inte är ldslig av organiska eller alkaliska losningsmedel, som fdrger och tusch innehAller, vilket gor att ovanndmnda klotter: losningsmedel inte Over tiden "kryper" genom skyddsbarridren utan kan senare ldtt avldgsnas helt med varmt vatten tillsammans med skyddsfilmen EXEMPEL 1 Detta exempel viii visa anvandningen av uppfinningen i praktiskt utovande, utan flagon inskrankande karaktar. exemplet anvands en blandning av tekniskt gelatin bestAende i huvudsak av, 80% protein, 3% fett, 3% aska, 2% tensider, 2% konserveringsmedel och 10% vatten i pulverform (>8 mesh). This is possible due to the fact that the animal film is not soluble in organic or alkaline solvents, which contain dyes and inks, which means that the above-mentioned graffiti: solvents do not over time "creep" through the protective barrier but can later be completely removed with hot water together with the protective film EXAMPLE 1 This example will illustrate the practice of the invention in a practically non-limiting nature. The example uses a mixture of technical gelatin consisting mainly of 80% protein, 3% fat, 3% ash, 2% surfactants, 2% preservative and 10% powdered water (> 8 mesh).

Tekniskt gelatin salufores av Tobas Lijimfabrik, Dongen, Holland, under handelsnamnet benlim. Technical gelatin is marketed by Tobas Lijimfabrik, Dongen, Holland, under the trade name benlim.

OvanstAende torrblandning reires ned i kallt vatten i forhAllandet 1 del pulver till 9 delar vatten. Namnda bland-fling fick sedan stA och svalla i 30 minuter. The above dry mixture is stirred into cold water in the ratio of 1 part powder to 9 parts water. Said mixed-fling was then allowed to stand and swell for 30 minutes.

Darefter varmeds blandningen till 45-°C, dar den svallda blandningen helt upploses i det uppvarmda vattnet. I detta f6rsta exemplet applicerades losningen pA en tegelvagg i ett skickt, till en kvantitet av ca 1,1 dl/ kvm. genom sprutning. The mixture is then heated to 45 ° C, where the cooled mixture is completely dissolved in the heated water. In this first example, the solution was applied to a brick wall in one condition, to a quantity of about 1.1 dl / sqm. by spraying.

Efter torktiden, i detta fall ca. 1 timme vid + 4C hade kompositionen bildat en helt osynlig film pA underlaget, bortsett frAn en viss blankhet. After the drying time, in this case approx. 1 hour at + 4C, the composition had formed a completely invisible film on the substrate, apart from a certain gloss.

Den bahandlade ytan nedklottrades sedan med sprayfarger, tusch, black, underredsmassa, flerkomponentslacker och vattenbaserad farg. The treated surface was then scribbled down with spray paints, ink, black, base material, multicomponent paints and water-based paint.

Efter en veckas torktid, kunde den nedklottrade vaggen snabbt och enkelt, med hjalp av hogtryckstvatt och 70- 8eC vatten latt rengoras. After a week of drying, the scribbled cradle could be cleaned quickly and easily, with the help of high-pressure water and 70-8eC of water.

Efter avslutat arbete kunde inte minsta spar av fdroreningen markas, vare sig pA tegel eller i cementfogarna. After completion of the work, not the slightest trace of the liner could be marked, either on bricks or in the cement joints.

EXEMPEL 2 Exempel 1 upprepades, denna gang med en tillsats av 1% mattleseringsmedel. EXAMPLE 2 Example 1 was repeated, this time with the addition of 1% matting agent.

Ingen blank yta kunde dA iaktagas pi den nedklottrade tegelvaggen. No shiny surface could be observed on the scribbled brick wall.

Saneringen gjordes vid detta tillfalle med hett vatten och styv borste. Samma resultat erh611s. The decontamination was done on this occasion with hot water and a stiff brush. The same result erh611s.

EXEMPEL 3 Exempel 2 upprepades med tekniskt gelatin under handelsnamnet hudlim, samma tillverkare, i ovrigt samma ingredienser, bortsett frin att hudlim innehiller mindre fett (ca. 1%), och luktar mindre i uppvarmt tillstAnd.Samma fdrfaringssatt som i ex. 1 och samma goda slutresultat. EXAMPLE 3 Example 2 was repeated with technical gelatin under the trade name skin glue, the same manufacturer, otherwise the same ingredients, except that skin glue contains less fat (approx. 1%), and smells less in a heated state. The same procedure as in ex. 1 and the same good end result.

EXEMPEL 4 Exempel 1 och 3 upprepades pa blanklackerad yta, denna ging utan mattleseringsmedel, di det var OnskvArt att behilla en blank yta. Samma goda slutresultat. EXAMPLE 4 Examples 1 and 3 were repeated on a glossy lacquered surface, this went without a matte reading agent, in which it was desirable to maintain a glossy surface. The same good end results.

EXEMPEL I detta exempel behandlas transparanta ytor sAsom glas och plexiplast, ddr stora krav pA skyddsfilmens transparens stalles. EXAMPLE In this example, transparent surfaces such as glass and plexiglass are treated, where great demands are made on the transparency of the protective film.

Bar anvands ett rent gelatinpulver (>8 mesh) som basamne, bestiende av 88% protein, o,1% fett, 2% aska, 1% salt, 2% konserveringsmedel, 2% tensider och resten vatten. Salufdres av Extrapo i Rlippan, Sverige. Rent gelatin framstalles i huvudsak av grishudar, till skillnad fan tekniskt gelatin som tillverkas av hud och ben frin notkreatur. Bar used a pure gelatin powder (> 8 mesh) as the base, consisting of 88% protein, 0.1% fat, 2% ash, 1% salt, 2% preservative, 2% surfactants and the rest water. Salufdres by Extrapo in Rlippan, Sweden. Pure gelatin is mainly produced from pig skins, unlike technical gelatin which is made from the skin and bones of cattle.

Blandningen, som i detta fall endast behover svAlla nAgra minuter i kallt vatten innan den yams upp till ca. °C, applicerades i detta fall med svamp. Efter torktiden pi ca. 30 minuter var filmen nastintill osynlig pi nAmnda ytor. Vid applicering med svamp lagges ett mycket tunt skickt vilket gOr att itgangen var ca. 0,5 dl/kvm. Efter sanering av sprayfarg och tuschstreck medelst tidigare namnda metoder, kunde ingen kvarvarande nedsmutsning urskiljas. The mixture, which in this case only needs to swell for a few minutes in cold water before it yams up to approx. ° C, was applied in this case with fungus. After the drying time of approx. For 30 minutes, the film was almost invisible on the aforementioned surfaces. When applying with a sponge, a very thin layer is applied, which means that the entrance was approx. 0.5 dl / sqm. After decontamination of spray paint and ink strokes by the previously mentioned methods, no residual contamination could be discerned.

EXEMPEL 6 Exempel 1,2,3,4 och 5 upprepas, denna ging med milsAttningen att ej offra skyddsfilmen, detta fOrfaringssatt är ytterst vardefullt och signifikant for denna filmbildarkomposition, di det galler att skyddaen yta som ar (g) kanslig for hogtryckstvatt och/eller me-kanisk natning eller lasningsmedel. EXAMPLE 6 Examples 1,2,3,4 and 5 are repeated, this went with the aim of not sacrificing the protective film, this method is extremely valuable and significant for this film-forming composition, in which it is necessary to protect the surface which is (g) sensitive to high pressure water and / or mechanical wetting or welding agents.

I detta exempel anvands aven en putsad yta !naiad med kalkfarg, vars handhavande har nedan beskrives. In this example, a plastered surface painted with lime paint is also used, the operation of which has been described below.

Efter nedklottringen, anvandes for sanering endast mjuk svamp och tygtrasor som verktyg. Svampen doppades vid detta tillfalle i etanol som sedan latt gnuggades Over den ytskyddsbehandlade kansliga ytan, farg och tusch Aterupplostes, och kan enkelt torkas bort med torr tygtrasa. Behandlingen med etanol och tygtrasa upprepades ytterligare en gang, far att fA ett fullgott slutresultat. Den skyddade ytan är halt intakt. After scrapping, only soft sponges and cloths were used as tools for decontamination. The sponge was dipped in this case in ethanol which was then easily rubbed over the surface-treated treated surface, paint and ink. Dissolved, and can be easily wiped off with a dry cloth. The treatment with ethanol and cloth was repeated once more, in order to obtain a satisfactory end result. The protected surface is slippery intact.

Skyddsfilmen bar vid detta tillfalle fungerat som en skyddsbarriar mellan klotter och den yta den ska skydda. Skyddsfilmen finns aven kvar pa den behandlade ytan, nAgot farsvagad, och ombehandling bar darfor alltid she far ett fullgott skydd skall garanteras. The protective film on this occasion served as a protective barrier between graffiti and the surface it is to protect. The protective film is also left on the treated surface, slightly weakened, and re-treatment should therefore always ensure full protection.
