In Geschirrspülmaschinen für Betriebe und Haushalte werden zum Spülen von Kosh- und Essgeschirr stark alkalische Lösungen verwendet* wobei man zum Spülen und Nachspülen im allgemeinen gewöhnliches Leitungswasser benutzt- Ein bekanntes Problem bei diesen Geschirrspülverfahren ist das Zurückbleiben von Flecken auf dem Geschirr, insbesondere auf Tellern und Gläsern, welche aus anorganischen Salzrückständen aus dem Leitungswasser bestehen. Außerdem stören Ablagerungen solcher Salze auf Tel.Xmder Geschirrspülmaschine die Arbeitsweise der Maschine„ so daß diese häufig gesäubert werden muß«, Die* Spülmittel enthalten im allgemeinen kondensierte Phosphate, d.h, PoIyphosphate, jedoch bilden sich hieraus bei höheren SpüJ/cemperaturen durch Hydrolyse schnell Orthosphosphatniederschlägeο Viele organische Verbindungen, von welche eine VerminderungUsed in dishwashers for businesses and households for washing kosh and dinnerware strongly alkaline Solutions used * whereby ordinary tap water is generally used for rinsing and rinsing is a known problem with these dishwashing processes leaving stains on dishes, especially plates and glasses made of inorganic materials Salt residues from the tap water. aside from that interfere with deposits of such salts on phone Xm of the dishwasher the mode of operation of the machine "so that it has to be cleaned frequently", the * detergent contained in the general condensed phosphates, i.e. polyphosphates, however, they develop from this at higher flushing temperatures Orthosphosphate precipitates o quickly due to hydrolysis Many organic compounds, one of which is a decrease

Als Alkalihydroxyd kann Natriumhydroxyd, Kaliumhydroxyd oder eine Mischung derselben verwendet werden» Das Hydroxyd kann auch bis zu einem,bestimmten Gradef Z0B=. bis zu 2C$0 durch mildere alkalische Verbindungen wie Natrium« oder Kaliumcarbonat oder Natrium oder Kaliumorthophosphat ersetzt werden„ Vorzugsweise wird jedoch Natriumhydroxyd und insbesondere Kaliumhydroxyd als einzige alkalische Komponente verwendet.Sodium hydroxide, potassium hydroxide or a mixture of these can be used as the alkali hydroxide. The hydroxide can also be used up to a certain degree f Z 0 B =. Up to 2C $ 0 can be replaced by milder alkaline compounds such as sodium «or potassium carbonate or sodium or potassium orthophosphate. However, sodium hydroxide and especially potassium hydroxide are preferably used as the only alkaline component.
Als Alkalipyrophosphat kann Natrium- oder Kailumpyrophosphat verwendet werden, wobei Tetrakailumpyrophosphat besonders bevorzugt wirdc Tripolyphosphate wie Natrium tripcIyphosphat sind Ln den erfindungsgemässen Geschirrspülmitteln nicht erforderlicheSodium or kailum pyrophosphate can be used as the alkali pyrophosphate, with tetrakailum pyrophosphate tripolyphosphates such as sodium are particularly preferred TripcIyphosphate are included in the dishwashing detergents according to the invention not required

Die wässrige Lösung des erfindungegemässen Geschirrspülmittels kann auf be* liebige Weise zur Behandlung des zu reinigenden Geschirrs eingesetzt werden, jedoch wurde das vorliegende Geschirrspülmittel insbesondere für die Verwendung in Geschirrspulmaschinen entwickelt, in welchen das spülroittelhaltige Wasser auf das Geschirr gespritzt wird und in welchen es zu besonders guten Ergebnissen führt. So wird beispielsweise mit diesen Geschirrspülmitteln in größeren Geschirrspülmaschinen, wie sie in Betrieben verbandet werden, eine ausgezeichnete Reinigungswirkung bei geringer Schaumentwicklung erzielto contains medium. The flushing temperature is generally 60 to 95 ° C and mostly 60 to 70 ° C. The aqueous solution of the dishwashing detergent according to the invention can be used in any way to treat the dishes to be cleaned, but the present dishwashing detergent was developed in particular for use in dishwashers in which the detergent-containing water is splashed onto the dishes and in which it is too special gives good results. For example, with these dishwashing detergents in larger dishwashers, such as those used in companies, an excellent cleaning effect with little foam development is achieved o
