Description

Schaumfeuerlöschmittel Zum Ersticken von Bränden sind zahlreiche schaumerzeugende Substanzen vorgeschlagen bzw. in Anwendung gebracht worden, die vielfach aber doch noch verbesserungsbedürftig erscheinen.Foam fire extinguishing agents There are numerous foam-generating agents used to suffocate fires Substances have been proposed or used, but in many cases they are still need improvement.

Es wurde nun gefunden, daß ein Zusatz einer geringen Menge alkylierter oder aralkylierter Sülfosäuren bzw. ihrer wasserlöslichen Salze zu mit Wasser anzuwendenden schaumerzeugenden Brandlöschmitteln die . Wirksamkeit bzw. Stabilität des Schaumes zu erhöhen vermag. Setzt man beispielsweise ein Natriumsalz der erwähnten Art zu einem an sich schaumgebenden Gemisch von Eisensalzen und Soda, so wird der Schaum in seinen Eigenschaften, insbesondere in seiner Stabilität und Hitzebeständigkeit, außerordentlich erhöht, was bei Brandfällen zu einer wesentlich intensiveren Wirkung des Schaumgemisches führt.It has now been found that the addition of a small amount of alkylated or aralkylated sulphonic acids or their water-soluble salts to be used with water foam-generating fire extinguishing agents the. Effectiveness and stability of the foam able to increase. For example, if a sodium salt of the type mentioned is added a mixture of iron salts and soda, which in itself produces a foam, then becomes the foam in its properties, especially in its stability and heat resistance, extraordinarily increased, which in the event of a fire has a much more intense effect of the foam mixture leads.

Beispiele i. Ein Sehaumlöschpulver wird hergestellt durch Vermischen von 56 Teilen technischem Aluminiumsulfat, 42 Teilen technischem Natriumbicarbonat und 2 Teilen butylnaphthalinsulfosaurem Natron (dargestellt aus 2 Mol. Butylalkohol, i Mol. Naphthalin und 6 MoI. Schwefelsäure und so viel Natronlauge, als zur Neutralisation des von der überschüssigen Schwefelsäure befreiten Reaktionsproduktes erforderlich ist). Zur Anwendung wird dieses Schaumlöschpulver mit Wasser gemischt, was zweckmäßig in einem Schaumgenerator geschieht, welcher in die Schlauchleitung eingeschaltet wird. Das Pulver kann jedoch auch zur Füllung von Handfeuerlöschapparaten bekannter Konstruktion dienen, wobei der Zutritt des ebenfalls im Apparat befindlichen Wassers zu dem Pulver erst im Benutzungsmoment bewerkstelligt wird.Examples i. A foam extinguishing powder is made by mixing of 56 parts of technical aluminum sulfate, 42 parts of technical sodium bicarbonate and 2 parts of butylnaphthalenesulfonate of soda (prepared from 2 mol. of butyl alcohol, i mol. naphthalene and 6 mol. Sulfuric acid and as much caustic soda as for neutralization of the reaction product freed from the excess sulfuric acid is required is). For use, this foam extinguishing powder is mixed with water, which is useful happens in a foam generator, which is switched into the hose line will. However, the powder can also be used for filling hand-held fire extinguishers Construction are used, whereby the access of the water also located in the apparatus to the powder is accomplished only in the moment of use.

2. Von den beiden Kammern oder Behältern eines Handfeuerlöschers wird eine Kammer gefüllt mit einer Lösung von 49 Gewichtsteilen Aluminiumsulfat, 5o Gewichtsteilen Wasser und i Gewichtsteil dibutylnaphthalinsulfosaurem Natrium, die andere mit der Lösung von 49 Gewichtsteilen Natriumbica.rbonat, 5oo bis iooo Gewichtsteilen Wasser und i Teil dibutylnaphthalinsulfosaurem Natrium. Die beiden Lösungen werden bei Ingebrauchnahme des Apparates miteinander vereinigt und bilden sofort etwa das zehnfache Volumen an dichtem, haltbarem Schaum.2. From the two chambers or containers of a hand-held fire extinguisher a chamber filled with a solution of 49 parts by weight of aluminum sulfate, 50 parts by weight Water and 1 part by weight of sodium dibutylnaphthalenesulfonate, the other with the Solution of 49 parts by weight of sodium bicarbonate, 500 to 100 parts by weight of water and i part of sodium dibutylnaphthalenesulfonate. The two solutions are at When the apparatus is put into use, they are combined with each other and immediately make about ten-fold Volume of dense, durable foam.
