JVe 215588 KLASSE 61 b. JVe 215588 CLASS 61 b.
Gegenstand der Erfindung ist die Verwendung der Rhodanerdalkalien zu Feuerlösch . zwecken.The invention relates to the use of the rhodan alkaline earths for fire extinguishing. purposes.
Die Rhodanerdalkalien, von denen als Beispiel das Rhodancalcium hier erwähnt sei, können entweder für sich oder in Gemeinschaft mit Ammoniumacetat in Anwendung gebfacht werden.The Rhodan-earth alkalies, of which the rhodan calcium is mentioned here as an example, can be used either on their own or in conjunction with ammonium acetate be panned.
Die Lösungen der Rhodanerdalkalien sind unbegrenzt haltbar, und zwar auch bei Zusatz von Ammoniumacetat, üben auf Gewebe, Holz, Mauerwerk usw. ausgespritzt keine nachteiligen Wirkungen aus und sind bis zu sehr hohen Kältegraden (bis etwa —450 C.) vollkommen frostbeständig. Außerdem zeichnen sich die genannten Lösungen dadurch aus, daß sie das Wiederanbrennen einmal gelöschter Körper wirksam verhindern, indem sie eine besonders kräftige Inkrustierung der Brandobjekte bewirken, die stärker ist als beispielsweise die bei der Verwendung von Rhodankalium erreichbare Inkrustierung.The solutions of Rhodanerdalkalien stored indefinitely, even with the addition of ammonium acetate, practicing on fabric, wood, masonry, etc. jetted no adverse effects, and are up to very high cold degrees completely frost resistant (to about -45 0 C.). In addition, the solutions mentioned are distinguished by the fact that they effectively prevent the re-burning of bodies once they have been extinguished by causing particularly strong incrustation of the objects to be burned, which is greater than, for example, the incrustation that can be achieved when using potassium rhodium.
Bei der ' gleichzeitigen Verwendung der Rhodanerdalkalien und des Ammoniumacetats entstehen Umsetzungsprodukte, die das Löschmittel beispielsweise zur Bekämpfung von Schornsteinbränden ■ sehr geeignet machen.With the 'simultaneous use of the rhodan-earth alkalies and ammonium acetate there are conversion products that use the extinguishing agent, for example, to combat Making chimney fires ■ very suitable.
Lösungen der erwähnten Stoffe und deren Mischungen können übrigens auch einen geringen Glyzerinzusatz erhalten. Indessen ist dieser Zusatz nicht unerläßlich.Incidentally, solutions of the substances mentioned and their mixtures can also have a small amount Glycerin added. However, this addition is not indispensable.
