Patentschrift stimmt mit der Auslegeschrift übereinThe patent specification corresponds to the patent specification
Im Hauptpatent 1219 331 ist ein Universallöschpulver gegen Brände flammen- und glutbildender fester, flüssiger und gasförmiger Stoffe und gegen Brände an elektrischen Anlagen unter Hochspannung auf der Basis von Ammoniumsulfat, Diammoniumphosphat und oder Monoammoniumphosphat mit einem Zusatz eines Zwei-Komponenten-Formaldehyd-Kondensationsharzes in Mengen unter 10% und gegebenenfalls mit bekannten Zusätzen zur Verbesserung der Riesclfähigkeit und der wasserabweisenden Figenschaften beansprucht worden.The main patent 1219 331 is a universal extinguishing powder against fires of flame and embers forming solid, liquid and gaseous substances and against fires on electrical systems under high voltage on the basis of ammonium sulfate, diammonium phosphate and / or monoammonium phosphate with an addition of a two-component formaldehyde condensation resin in quantities under 10% and possibly with known additives to improve the pourability and the water-repellent properties.
Dieses Zwei-Komponenten-Formaldehyd-Kondensationsharz besteht aus einem Gemisch von Formaldehydkresolliarz und Asbestmehl (I).This two-component formaldehyde condensation resin consists of a mixture of formaldehyde cresol resin and asbestos flour (I).
Fs wurde gefunden, daß bei der Zumischung von Schlcifstäuhcn (II). wie sie bei der Herstellung von Bremsbelägen. Dämmstoffen, rutschfesten Bodenbeschlagen und ähnlichen Kunststoffpreßmassen aui der Basis von mit Formaldehydkresolharz gebundenem Asbestmehl anfallen, mindestens die gleichen löschlechnischen günstigen Hflekle erzielt werden, wie bei der Zuniischung eines Zwei-Komponenten-Formaldehyd-Kondeiisationsharzes. Außerdem werden darüber hinaus die Riesel-. Folder- und Lagerfähigkeit \crbessert.It was found that when Schlcifstäuhcn (II). as they do in the manufacture of Brake pads. Insulation materials, non-slip floor fittings and similar plastic molding compounds the basis of asbestos powder bound with formaldehyde cresol resin are at least the same In terms of extinguishing technology, it is possible to achieve favorable properties, such as the admixture of a two-component formaldehyde conditioning resin. In addition, the trickle. Folder and storability \ crimproved.
Die Meßapparatur für die Bestimmung der Riesellähigkeit besteht aus zwei miteinander verbundenen Fnghals-F.rlenmeycrkolben mit einem Volumen von 500 ml. In einem Kolben befinden sich 300 g des zu prüfenden Trockenlöschpulvers Das Pulver rieseil nach dem »Sanduhrprinzip" aus dem oberen in den unteren Kolben, wobei der Mittelwert der Rieselzeit aus 10 Messungen gebildet wird. Die Werte betragen dabei tür (I) ζ. B. Cv bis 8 Sekunden und für (11)4 bis h Sekunden. ·The measuring apparatus for determining the flowability consists of two interconnected double-neck flasks with a volume of 500 ml. 300 g of the dry extinguishing powder to be tested are in a flask according to the "hourglass principle" from the upper to the lower flask, with the mean value of the flow time is formed from 10 measurements. The values are thereby door (I) ζ. B. Cv up to 8 seconds and for (11) 4 to h seconds. ·
Die Fördertähigkeit wird dadurch bestimmt, daß 4 kg iles Trockenlöschpulvers in einen Druckbehälter gegeben werden. Mittels Stickstoff wird ein Druck von 10 kp cm- auf das "Pulver gegeben, welches nach kurzer Yerweilzeit über ein etwa 6 m langes Schlangenrohr mit einem Innendurchmesser von 8 mm aus dem Behälter ausgetrieben wird. Die Förderfähigkeil IJniversallöschpulverThe ability to be conveyed is determined by placing 4 kg of dry extinguishing powder in a pressure vessel are given. A pressure of 10 kp cm- is applied to the "powder" by means of nitrogen, which after short dwell time via an approximately 6 m long coiled tube with an inner diameter of 8 mm is driven out of the container. The Eligibility Wedge IJniversal Extinguishing Powder

beträgt dabei für (I) etwa 50 bis 60 g/Sek. und für (II) etwa 60 bis 70 g'Sek.for (I) is about 50 to 60 g / sec. and for (II) about 60 to 70 g'Sec.
Die Lagerfähigkeit wurde erprobt in einem einmonatigen Dauerversuch auf einer Rüttelmaschine. Dabei konnte ein etwas besseres Verhalten bei (II) gegenüber (I) festgestellt werden.The shelf life was tested in a one-month long-term test on a vibrating machine. Somewhat better behavior was found for (II) compared to (I).
