Description
Trockenlöschpulver für sämtliche Brandklassen In der Hauptpatentanmeldung L 20193 IVa/61 b ist ein Feuerlöschpulver für alle Klassen von Feuern beschrieben, welches aus einer ersten Mischung aus 74% Ammoniumsulfat, 15% Diammoniumphosphat, 9% Natriumbicarbonat und 2% Stearinsäure besteht. Dieser Mischung l wird eine Mischung Il aus 94% Natriumbicarbonat, 4% Kieselgur und 2% Stearinsäure zugemischt. 100 Gewichtsteile der Mischung l ergeben mit 40 Gewichtsteilen der Mischung II das gewünschte Pulver.Dry extinguishing powder for all fire classes In the main patent application L 20193 IVa / 61 b describes a fire extinguishing powder for all classes of fire, which consists of a first mixture of 74% ammonium sulfate, 15% diammonium phosphate, 9% sodium bicarbonate and 2% stearic acid. This mixture l becomes a mixture II of 94% sodium bicarbonate, 4% kieselguhr and 2% stearic acid mixed in. 100 parts by weight Mixture I gives the desired powder with 40 parts by weight of mixture II.
Es wurde gefunden, daß es nicht unbedingt erforderlich ist, daß die angegebenen Prozentsätze der einzelnen Stoffe eingehalten werden. Vielmehr hat sich gezeigt, daß es im wesentlichen darauf ankommt, zunächst eine Mischung aus Ammoniumsulfat und Diammoniumphosphat fein zu mahlen und vorzutrocknen, worauf Natriumbicarbonat und Stearinsäure zugesetzt werden. Die so hergestellte Mischung I wird mit der zweiten Mischung vermischt, die ihrerseits aus Natriumbicarbonat, Kieselgur (Diatomeen-Erde) und Stearinsäure besteht.It has been found that it is not absolutely necessary that the specified percentages of the individual substances are adhered to. Rather, it has showed that it essentially comes down to a mixture of ammonium sulfate first and diammonium phosphate finely grind and predry, after which sodium bicarbonate and stearic acid can be added. The mixture I prepared in this way is with the second Mixture, which in turn consists of sodium bicarbonate, kieselguhr (diatomaceous earth) and stearic acid.
In beiden Mischungen kann die Stearinsäure zum Teil oder ganz durch ein Metallstearat ersetzt werden. Die Zusammenmischung der Mischung I mit der Mischung 1I ergibt ein Trockenlöschpulver, welches neben seiner Eignung zur Bekämpfung aller Klassen von Feuern auch den großen Vorzug hat, daß es lange Zeit lagern kann, ohne Feuchtigkeit aus der Luft aufzunehmen, so daß es nicht backt und infolgedessen jederzeit zur Feuerbekämpfung verwendet werden kann.In both mixtures, the stearic acid can partially or completely a metal stearate can be replaced. Mixing the mixture I together with the mixture 1I results in a dry extinguishing powder which, in addition to its suitability for combating all Classes of fires also has the great advantage that it can be stored for a long time without To absorb moisture from the air so that it does not bake and, as a result, at all times can be used for fire fighting.
