Description
Verfahren zur Herstellung von Spül-, Entfettungs- und Reinigungsinittelri Zum Reinigen von Messing und Kupfer sind bereits flüssige, Natriumphosphat, Natriumcarbonat und Natriumsilikat enthaltende Lösungen vorgeschlagen worden. Die technische Herstellung dieser Reinigungsmittel in fester Form durch Mischen der Bestandteile in Mischmaschinen, Kollermühlen u. dgl. stößt insofern auf Schwierigkeiten, als die hierbei gewonnenen Mischungen nicht lagerbeständig sind, sondern zum Zusammenbacken und Klumpen neigen.Process for the production of rinsing, degreasing and cleaning agents For cleaning brass and copper are already liquid, sodium phosphate, sodium carbonate and solutions containing sodium silicate have been proposed. The technical production these cleaning agents in solid form by mixing the ingredients in mixing machines, Kollermühlen and the like encounter difficulties insofar as those gained in this way Mixtures are not storage-stable, but tend to stick together and lump.
Auch bei den Versuchen, Lösungen von Alkaliphosphaten, Alkalicarbonaten und wasserlöslichen Silikaten in den üblichen Zerstäubungsapparaten zu zerstäuben, gelang es nicht, ein fein verteiltes, homogenes Gemisch zu erhalten, da das Produkt ständig in zusammengeballten Klumpen und Krusten anfiel.Even when trying to find solutions of alkali phosphates, alkali carbonates and water-soluble silicates to be atomized in conventional atomizers, did not succeed in obtaining a finely divided, homogeneous mixture because the product constantly accumulated in clumped lumps and crusts.
Es hat sich nun gezeigt, daß diese Schwierigkeiten, die auf die Anwesenheit der kolloidalen Kieselsäureverbindungen zurückzuführen sind, beseitigt werden können, wenn man der aus alkalisch reagierenden Alkaliphosphaten und löslichen Silikaten bestehenden Lösung im Augenblick des Zerstäübens ca.lcinierte Soda in Pulverform zuführt. Die Zuführung der Soda kann dabei durch verschiedene technisch übliche Mittel, so z. B. Einblasen oder Einsaugen in die Zerstäubungszone, geschehen.It has now been shown that these difficulties affect the presence the colloidal silicic acid compounds can be eliminated, if one of the alkaline reacting alkali phosphates and soluble silicates existing solution at the moment of atomizing about iced soda in powder form feeds. The soda can be fed in by various technically common methods Means such as B. blowing or sucking into the atomization zone, done.
Das fertige Produkt wird in sehr fein zerteilten, vollkommen homogenen Teilchen, die in Wasser sehr leicht löslich sind, erhalten. Eine Entmischung in die Einzelkomponenten tritt nicht ein, anscheinend weil die einzelnen Partikelchen der Mischungskomponenten nicht lose nebeneinander liegen, sondern innig miteinander verkittet sind. Aus dem gleichen Grunde kann sich auch eine verschiedene Auflösungsgeschwindigkeit der einzelnen Komponenten nicht störend bemerkbar machen.The finished product will be very finely divided, perfectly homogeneous Particles that are very easily soluble in water are obtained. A segregation in the individual components do not enter, apparently because the individual particles of the mixture components do not lie loosely next to one another, but intimately with one another are cemented. For the same reason, there can also be a different speed of dissolution of the individual components are not noticeable in a disruptive manner.
Das erhaltene Produkt ist daher gut lagerfähig, frei fließend und backt nicht.The product obtained is therefore easy to store, free-flowing and does not bake.
Die Gegenwart von Soda in den auf diese Weise hergestellten Spül-, Entfettungs- und Reinigungsmitteln bringt keinerlei Nachteile mit sich; sie ist im Gegenteil vorteilhaft und erwünscht.The presence of soda in the dishwashing, Degreasing and cleaning agents do not have any disadvantages; she is on the contrary, beneficial and desirable.
Als alkalisch reagierende Alkaliphosphate kann man sekundäre und tertiäre Alkaliphosphate sowie deren Mischungen mit Ätzalkalien verwenden.As alkaline reacting alkali metal phosphates can be secondary and tertiary Use alkali phosphates and their mixtures with caustic alkalis.
Bei der Verwendung von Mischungen sekundärer Alkaliphosphate mit Ätzalkalien gewinnt man den Vorteil, daß die besondere Arbeitsstufe der Herstellung der tertiären Alkaliphosphate wegfällt.When using mixtures of secondary alkali phosphates with caustic alkalis one gains the advantage that the particular stage of production of the tertiary No alkali phosphates.
Beispiel Eine Lösung von 130 kg Natronlauge (50 °/oig), 153 kg handelsüblichem Wasserglas (38 bis q.o° Be) und 622 kg Dinatriumphosphat (Na, HP04 12 aq) wird bei einer Temperatur von ioo bis io5° C in einer üblichen Zerrstäubungsapparatur zerstäubt. Gleichzeitig wird durch ein Zuführungsrohr pulverförmige, calcinierte Soda in die Zerstäubungszone geblasen, wobei man durch eine Dosiervorrichtung dafür Sorge trägt, daß in der Zeiteinheit, in der 9o5 Teile der :Mischung zerstäubt werden, i36 Teile calcinierte Soda eingeblasen werden.EXAMPLE A solution of 130 kg of sodium hydroxide solution (50%), 153 kg of commercially available water glass (38 to qo ° Be) and 622 kg of disodium phosphate (Na, HP04 12 aq) is at a temperature of 100 to 100 ° C in a conventional atomization apparatus atomized. At the same time, powdery, calcined soda is blown into the atomization zone through a feed pipe, care being taken by a metering device that in the unit of time in which 905 parts of the mixture are atomized, 136 parts of calcined soda are blown in.
Das Mischprodukt aus Wasserglas, Natriumphosphat und Soda fällt als sehr fein zerteilte, vollkommen homogene Masse an, deren einzelne Teilchen aus innig miteinander verkitteten Partikelchen bestehen. Das Produkt löst sich sehr schnell und gleichmäßig in Wasser; eine Entmischungsgefahr besteht nicht. Infolgedessen eignet es sich besonders als Reinigungs- und Spülmittel für den Haushalt.The mixed product of water glass, sodium phosphate and soda falls as very finely divided, completely homogeneous mass, the individual particles of which are intimately consist of small particles cemented together. The product dissolves very quickly and evenly in water; there is no risk of segregation. Consequently it is particularly suitable as a cleaning and washing-up liquid for the household.
Es ist bereits bekannt, Wasserglaslösungen unter Zufuhr von Natriumsulfat auf dem Zerstäubungswege zu trocknen. Diese Arbeitsweise läßt sich aber bei dem vorstehenden Verfahren, bei dem es sich nicht um reine Wasserglaslösungen, sondern um Gemische solcher mit großen Mengen von alkalisch reagierenden Alkaliphosphaten, insbesondere Trinatriumphosphat, handelt, nicht anwenden. Außer den technischen Schwierigkeiten würde durch den Zusatz von Natriumsulfat das Reinigungsmittel in seiner reinigenden Wirkung nur verschlechtert werden, da das Natriumsulfat nur einen unnötigen Ballast darstellen würde. Infolgedessen eignet sich für die Zerstäubungstrocknung derartiger Mischungen Natriumsulfat nicht, sondern hierfür hat sich nur calcinierte Soda als geeignet herausgestellt.It is already known to use water glass solutions with the addition of sodium sulfate to dry by atomization. This way of working can be used with the above process, which is not pure water glass solutions, but to mixtures of those with large amounts of alkaline reacting alkali phosphates, especially trisodium phosphate, do not use. Except the technical ones Difficulties would arise from the addition of sodium sulfate in the detergent its cleansing effects will only be worsened since the sodium sulfate only has one would represent unnecessary ballast. As a result, it is suitable for spray drying Such mixtures are not sodium sulfate, but only calcined for this purpose Soda found suitable.
