Abstract
Description
Oppfinnelsen vedrører et alkalisk og klorstabilt rengjørings-middel som fortrinnsvis er egnet til anvendelse i oppvask-maskiner og som vesentlig bestanddel inneholder et blandingsgranulat som overveiende består av fosfater, silikater og hjelpestoffer. The invention relates to an alkaline and chlorine-stable cleaning agent which is preferably suitable for use in dishwashers and which contains as an essential component a mixed granulate which predominantly consists of phosphates, silicates and auxiliaries.
Oppvask- eller rengjøringsmidler for apparatrensning i næringsmiddelindustrien inneholder vanligvis alkalifosfater, fortrinnsvis natriumtrifosfat, alkalisilikater- karbonater, bikarbonater, -hydroksyder, skumfattige ikke-ionogene tensider, oksydative blekemidler, spesielt aktivkloravspaltende forbindelser, samt korrosjonsinhibitorer og klorstabilisatorer. Dishwashing or cleaning agents for appliance cleaning in the food industry usually contain alkali phosphates, preferably sodium triphosphate, alkali silicates-carbonates, bicarbonates, -hydroxides, low-foaming non-ionic surfactants, oxidative bleaches, especially active chlorine-releasing compounds, as well as corrosion inhibitors and chlorine stabilizers.
Funksjonen av de enkelte rengjøringsmiddelkomponenter bestårThe function of the individual cleaning agent components consists
i at natriumtrifosfat komplekst binder vannets hårdhetsdannere, mens alkalisilikater sterkt hindrer korrosjoner av oppvaskgjenstander som f.eks. glass, porselen, bestikk, edelstålmaterialer og lignende. Alkalikairbonater, -bikaron-ater og -hydroksyder øker rengjøringsvirkningen av rengjørings-midlene og befrir oppvaskgjenstandene spesielt for plante- og dyrisk fett. Ved hjelp av oksydative blekemidler fjernes farvetilsmussinger, som f.eks. te, kaffe, frukt- og grønnsak-safter fra oppvaskgjenstanden, mens tensidene øker oppvask-gjenstandenes fuktbarhet. in that sodium triphosphate complexly binds the water's hardness generators, while alkali silicates strongly prevent corrosion of washing-up items such as e.g. glass, porcelain, cutlery, stainless steel materials and the like. Alkali carbonates, bicarbonates and hydroxides increase the cleaning effect of the cleaning agents and free the dishes, especially from vegetable and animal fat. With the help of oxidative bleaching agents, color stains are removed, such as e.g. tea, coffee, fruit and vegetable juices from the dishes, while the surfactants increase the wettability of the dishes.
Moderne oppvarskmidler må være ikke-støvende, god risle-dyktige og hurtig oppløselige i vann. De må dessuten danne et fra oppvaskmaskinens doseringsinnretninger godt og fullstendig utspylbart produkt og i oppbevaring av en høy lagringsstabilitet med hensyn til aktivkloravspaltende forbindelser.. Modern cleaning agents must be non-dusty, have good trickle-ability and quickly dissolve in water. They must also form a product that can be easily and completely rinsed from the dishwasher's dosing devices and, in storage, have a high storage stability with regard to active chlorine-releasing compounds.
For å bedre utspylbarheten av oppvaskmiddelet fra doserings-innretningene og å hindre en sammenbakning av produktet inneholder handelsvanlige rengjøringsmidler fortrinnsvis del-hydratiserte råstoffer eller de granuleres ved hjelp av vann. Det til granuleringen nødvendige vann og/eller råstoffenes krystallvann bevirker imidlertid en hurtig nedbrytning av de i rengjøringsmidlene inneholdt aktivkloravspaltende forbindelser som f.eks. diklorisocyanurater. Denne uønskede effekt som fører til en vesentlig dårligere rengjørings-virkning av rengjøringsmiddelet forsøkte man som omtalt i DE-AS 23 50 295 mest mulig å hindre ved anvendelse av stabilisator for den aktivkloravspaltende forbindelse. In order to improve the washability of the washing-up liquid from the dosing devices and to prevent caking of the product, commercial cleaning agents preferably contain partially hydrated raw materials or they are granulated using water. The water required for the granulation and/or the crystal water of the raw materials, however, causes a rapid breakdown of the active chlorine-releasing compounds contained in the cleaning agents, such as e.g. dichloroisocyanurates. As mentioned in DE-AS 23 50 295, an attempt was made to prevent this unwanted effect, which leads to a significantly worse cleaning effect of the cleaning agent, as much as possible by using a stabilizer for the active chlorine-releasing compound.
En begunstigelse av den for tidlige spaltning av de aktiv-klorspaltende forbindelser med vann i fravær av spesielle stabilisatorer inntrer også når gjengjøringsmiddelet inneholder hydroskopiske komponenter som f.eks. alkalisilikater. En granulering av alkalisilikatene med natriumtripolyfosfat i henhold til fremgangsmåten ifølge DE-AS 24 54 448 er ikke tilstrekkelig til å fjerne overnevnte ulempe med alkalisilikatene da det i granulatet, dvs. også på granulatpartiklenes overflate er granulatbestanddelene homogent fordelt og derved hindres ikke et vannopptak av silikater. Granulatet tenderer også i dette tilfelle til sammenbakning. A favoring of the premature splitting of the active chlorine-splitting compounds with water in the absence of special stabilizers also occurs when the restoring agent contains hydroscopic components such as e.g. alkali silicates. A granulation of the alkali silicates with sodium tripolyphosphate according to the method according to DE-AS 24 54 448 is not sufficient to remove the above-mentioned disadvantage of the alkali silicates, as the granulate components are homogeneously distributed in the granulate, i.e. also on the surface of the granulate particles, and thereby water absorption by silicates is not prevented . In this case, the granules also tend to stick together.
En delløsning av det i et foregående påviste problem erA partial solution to the previously proven problem is
det i DE-AS 28 22 765 åpenbarte granulat. Det dreier seg herved om et granulert råmateriale for vask-, fettfjerning- the granules disclosed in DE-AS 28 22 765. This concerns a granulated raw material for washing, degreasing
og rengjøringsmiddel-tilberedninger som i det vesentlige består av natrium- eller kaliumsilikat eller -tripolyfosfat og hvor silikatet er beskyttet mot kontakt med fuktighet, and cleaning agent preparations which essentially consist of sodium or potassium silicate or -tripolyphosphate and where the silicate is protected against contact with moisture,
C02, tensider, klorholdige blekemidler og andre bestand-C02, surfactants, chlorine-containing bleaches and other ingredients
deler av den endelige tilberedning som videre ved oppløsning i hårdt vann ikke fører til en utfelling av slørdannende svakt oppløselig kalsiumsilikater, hvilket erkarakterisertved at det består av en indre silikatkjerne og et ytre sjikt, idet minste av delvis hydratisert tripolyfosfat, parts of the final preparation which, when further dissolved in hard water, do not lead to a precipitation of veil-forming, slightly soluble calcium silicates, which is characterized by the fact that it consists of an inner silicate core and an outer layer, the smallest of partially hydrated tripolyphosphate,
idet hydratiseringsgraden bestemmes av vannmengden som kreves til belegg av silikatkornene med tripolyfosfat. the degree of hydration being determined by the amount of water required to coat the silicate grains with tripolyphosphate.
Det kjente granulat anses derfor som fordelaktig som be standdel av rengjøringsformuleringer fordi f.eks. ved anvendelse av hårdt vann i oppvaskmaskinen binder det primært oppløste tripolyfosfat vannets hårdhetsdannere komplekst på forhånd og således hindres den etterfølgende dannelse av tungtoppløselige kalsium- og magnesiumsilikater fra granu-latkjernens stoff. The known granules are therefore considered advantageous as part of cleaning formulations because e.g. when using hard water in the dishwasher, the primarily dissolved tripolyphosphate binds the water's hardness formers complexly in advance and thus prevents the subsequent formation of poorly soluble calcium and magnesium silicates from the substance of the granulate core.
Granulatet ifølge DE-AS 28 22 765 er imidlertid beheftet med den ulempe at det bare består av to komponenter, nemlig alkalisilikat og tripolyfosfat. Til fremstilling av oppvaskmidler eller rengjøringsmidler til rengjøring av bruks-gjenstander og maskiner, f.eks. for næringsmiddelindustrien er imidlertid det kjente granulat ikke alene tilstrekkelig. Eksempelvis må det i en industriell oppvaskmaskin på grunn However, the granulate according to DE-AS 28 22 765 suffers from the disadvantage that it only consists of two components, namely alkali silicate and tripolyphosphate. For the production of washing-up agents or cleaning agents for cleaning utility objects and machines, e.g. for the food industry, however, the known granules alone are not sufficient. For example, it must be in an industrial dishwasher
av de korte rengjøringstider som utgjør delvis bare 40 sekunder anvendes oppvaskmidler med en høyere alkalitet. of the short cleaning times, which amount to only 40 seconds in some cases, detergents with a higher alkalinity are used.
For å oppnå den nødvendige alkalitetsgrad er det nødvendigIn order to achieve the required degree of alkalinity, it is necessary
i rengjøringsmidlene å innføre høyalkaliske komponenter fortrinnsvis alkalihydroksyder og- karbonater ved siden av det foran nevnte blandingsgranulat samt ikke-ionogene skumfattige tensider og aktivkloravspaltende stoffer. in the cleaning agents to introduce high-alkaline components, preferably alkali hydroxides and carbonates, alongside the above-mentioned mixed granules as well as non-ionic low-foam surfactants and active chlorine-releasing substances.
Anvendelsen av terke alkaliske forbindelser, spesieltThe use of strong alkaline compounds, in particular
natrium- eller kaliumhydroksyder i rengjøringsformuleringene er imidlertid meget problematisk da de ødelegger de i opp-vaskrengjøringsmidler hyppig anvendte ikke-ionogene tensider eller ved deres hydroskopiske egenskaper opptar vann fra omgivelsene og således sterkt akselererer nedbrytningen av aktivklorholdige forbindelser som diklorisocyanurater. sodium or potassium hydroxides in the cleaning formulations is, however, very problematic as they destroy the non-ionic surfactants frequently used in dishwashing detergents or, due to their hydroscopic properties, absorb water from the surroundings and thus strongly accelerate the breakdown of active chlorine-containing compounds such as dichloroisocyanurates.
Oppfinnelsens gjenstand er nu en alkalisk og klorstabilt rengjøringsmiddelblanding som ikke har de overnevnte ulemper og minst inneholder et Co-granulat på basis av et alkalimetasilikat.

According to a preferred embodiment of the mixture according to the invention, the foam-poor surfactant is a non-ionic wetting agent, which can for example be prepared from ethylenediamine, ethylene oxide and propylene oxide and a chiro-releasing compound sodium dichloroisocyanate with two crystal waters.
Videre er det til fremstilling av Co-granulatet egnedeFurthermore, they are suitable for the production of Co granules

1. Fremstilling av Co-granulatet:1. Production of the Co-granules:
I hvirvelsjiktgranulatoren ifølge eksempel 1 ble det fyltIn the fluidized bed granulator according to example 1, it was filled
14 kg natriummetasilikatpulver som inneholdt 20 vekt-%14 kg of sodium metasilicate powder containing 20% by weight
fritt etsnatron og ved en tilluftstemperatur på 135°C bragt til en produkttemperatur på 9 0°C. Ved denne temperatur ble det gjennom en to-stoff dyse ved et forstøvningslufttrykk på 1,5 bar innsprøytet 16 kg av en 15 vekt-%ig natrium-hydrogenkarbonatoppløsning av 60°C nedenfra i hvirvelsjiktet. Det dannede granulat ble videre behandlet med 5 kg tørt, finmalt natriumtripolyfosfat samt 2,5 kg av en 20%ig natriumtripolyfosfatsuspensjon. Det ble igjen anvendt 250 m 3/time hvirvelluft av en temperatur på 150°C. Det resulterende Co-granulat hadde følgende sammensetning: free caustic soda and at a supply air temperature of 135°C brought to a product temperature of 90°C. At this temperature, 16 kg of a 15% by weight sodium hydrogen carbonate solution of 60°C was injected from below in the fluidized bed through a two-material nozzle at an atomizing air pressure of 1.5 bar. The formed granules were further treated with 5 kg of dry, finely ground sodium tripolyphosphate and 2.5 kg of a 20% sodium tripolyphosphate suspension. Again, 250 m 3 /hour of swirling air at a temperature of 150°C was used. The resulting Co granulate had the following composition:
46.7 vekt-% natriummetasilikat46.7% by weight sodium metasilicate
6,5 vekt-% etsnatron6.5% by weight caustic soda
16.8 vekt-% soda16.8 weight-% soda ash
25,0 vekt-% fosfat25.0% by weight phosphate
5,0 vekt-% vann.5.0 wt% water.
2. Fremstilling av rengjøringsmiddelblandingeh under anvendelse av Co-granulatet ifølge avsnitt 1: 95 vektdeler av det ifølge punkt 1 fremstilte Co-granulat ble i en frittfallblander blandet med 2m5 vektdeler av et ikke-ionisk tensid samt 2,5 vektdeler natriumdiklorisocyanurat x 2H2O. Tensidet var kondensasjonsproduktet av en langskjedet lineær alkohol med etylen- og propylenoksyd. Blandingen ble oppbevart over et tidsrom på 3 måneder i godt lukkede glassflasker og deretter tre måneder i åpne glass. En misfargning av rengjøringsmiddelblandingen ved spaltning av tensidét på grunn av nærvær av NaOH i blandingen inntrådte ikke under lagringstiden, hvilket er et bevis for blandingens stabilitet. 2. Preparation of cleaning agent mixture using the Co granulate according to section 1: 95 parts by weight of the Co granulate produced according to point 1 was mixed in a free-fall mixer with 2 m5 parts by weight of a non-ionic surfactant and 2.5 parts by weight sodium dichloroisocyanurate x 2H2O. The surfactant was the condensation product of a long-chain linear alcohol with ethylene and propylene oxide. The mixture was stored over a period of 3 months in tightly closed glass bottles and then three months in open jars. Discoloration of the detergent mixture by cleavage of the surfactant due to the presence of NaOH in the mixture did not occur during the storage period, which is a proof of the stability of the mixture.
Sammenligningsmessig skal det bemerkes at tilsvarende handelsvanlig rengjøringsformuleringer i nærvær av NaOH som bestanddel av formuleringen i kort tid misfarger seg under spaltning av tensidet, hvilket er forbundet en nedsettelse av rengjør-ingsmiddelets rengjøringsvirkning. In terms of comparison, it should be noted that corresponding commercially available cleaning formulations in the presence of NaOH as a component of the formulation discolour for a short time during the breakdown of the surfactant, which is associated with a reduction in the cleaning effect of the cleaning agent.
