Description

Als Reinigungs- und Spülmittel für technische und Haushaltungszwecke, besonders wo es sich um die Beseitigung fetthaltiger Verunreinigungien handelt, hat man in den letzten Jahren in ,steigendem Maße Trinatriumphosphat allein oder in Mischungen mit Soda in einer 2- bis 50/oigen wässerigen Lösung verwendet. Diese stark alkalischen Salzlösungen greifen aber bekanntlich Metalle,As a cleaning and rinsing agent for technical and household purposes, especially where it involves eliminating fatty Trisodium phosphate has become increasingly common in recent years Used alone or in mixtures with soda in a 2 to 50% aqueous solution. These highly alkaline salt solutions but are known to attack metals,

to wie Aluminium, Zink und Zinn, sehr leicht unter WasserstoffientwicHung an. Lange Zeit hat man deshalb derartige Produkte zu obengenanntem Zweck in Deutschland nicht gern verwendet.like aluminum, zinc and tin, very easily with the evolution of hydrogen. Long time This is why Germany does not like such products for the above-mentioned purpose used.

Es ging nun das Bestreben dahin, ein Universakeinigungsmittel zu finden, das gestattet, Gegenstände aus diesen Metallen oder Metallteilen zu reinigen, ohne sie dabei anzugreifen. Man hat zu diesem Zweck bereits vorgeschlagen, Trinatriumphosphat-Soda-Mischungen mit Wasserglas zu versetzen. Demgegenüber stellt die vorliegende Erfindung eine weitere Lösung des vorstehend gekennzeichneten Problems auf anderem Wege dar.The endeavor was now there, a universal detergent that allows objects made of these metals or metal parts to be cleaned without attacking them. It has already been proposed to use trisodium phosphate-soda mixtures for this purpose to be mixed with water glass. In contrast, the present invention provides a further solution to the above Problem in another way.

Es wurde nämlich die überraschende Beobachtung gemacht, daß 'ein Zusatz von Aluminiumsulfat, vorzugsweise in Mengen von 15 bis 20 0/0, zu Trinatriumphosphat oder einer Mischung von Trinatriumphosphat und Soda Metalle, wie Alurninium, Zink oder Zinn, praktisch unangreifbar' für diese alkalischen Salzlösungen macht. Eine derartige Mischung stellt infolgedessen ein für diese Zwecke gleichmäßig befriedigendes Reinigungsmittel dar. ■The surprising observation was made that 'an addition of aluminum sulphate, preferably in amounts of 15 to 20 0/0, to trisodium phosphate or one Mixture of trisodium phosphate and soda metals, such as aluminum, zinc or tin, practically invulnerable to these alkaline salt solutions. Such a mix consequently provides a cleaning agent that is uniformly satisfactory for these purposes represents. ■

Man hat schon Trinatriumphosphat und Alunxiniumsulfat enthaltende Mittel in der Textilausrüstung angewendet, insbesondere zum Zwecke des Füllens und Beschwerens der Textilfaser. Demgegenüber besitzt das neue Reinigungsmittel eine korrosionsschützende Wirkung auf alkaJiempfindliche Metalle, wie Aluminium, Zink und Zinn. Zufolge des sich in der stark alkalischen Lösung bildenden Tonerdehydrats wird neben der reinigenden auch noch eine die Veirunreinigungen absorbierende Komponente eingeführt, die ausgezeichnete Wirkungen zur Folge hat.Agents containing trisodium phosphate and aluminum sulfate are already in use Textile finishing used, especially for the purpose of filling and weighting the textile fiber. In contrast, the new cleaning agent has a corrosion protection Effect on alkali-sensitive metals such as aluminum, zinc and tin. As a result the alumina hydrate that forms in the strongly alkaline solution is next to the cleaning also introduced a component which absorbs the impurities results in excellent effects.
