Description

Löschmittel Die Erfindung besteht in einem Löschmittel, welches für die verschiedenartigsten Brände Anwendung finden kann. Das Löschmittel besteht in Schwefelhexafluorid (SF") Es sind flüssige Feuerlöschmittel bekannt, die aus Haloiden des Schwefels bestehen, aber doch Oxyhaloidverbindungen sind. Diese Löschmittel sollen dadurch löschend wirken, daß sie durch die Hitze des Brandes zerfallen bzw. gespalten werden und verschiedene schwere Löschgase bilden. Demgegenüber soll gemäß der vorliegenden Erfindung das t.öschmittel aus Schwefelhexafluori.d bestehen, welches bei normalen Temperaturen ein völlig indifferentes Gas ist. Das Schwefelhexafluorid hat eine sehr große Löschfähig -keit. Es ist fünfmal so schwer als die Luft und sinkt infolgedessen leicht zu Boden und hält sich somit gut bei Abdeckung von brennenden Objekten. Zudem ist seine Diffusionsgeschwindigkeit entsprechend dem hoben Molekulargewicht (1q.6) verhältnismäßig gering (das o,45fache der von Luft), so daß es auch aus diesem Grunde das Brandobjekt gut eingehüllt erhält. Weiterhin ist das Mittel so indifferent wie etwa Stickstoff. Es reagiert fast gar nicht mit anderen Stoffen, selbst nicht bei Erwärmung mit Natriummetall. Es ist daher auch völlig ungiftig und somit verschiedenen anderen als Löschmittel verwendeten Gasen bzw. leicht verdampfenden Stoffen vorzuziehen.Extinguishing agent The invention consists in an extinguishing agent, which for the most varied of fires can be used. The extinguishing agent consists of Sulfur hexafluoride (SF ") Liquid fire extinguishing agents are known that consist of haloids of sulfur, but are oxyhaloid compounds. These extinguishing agents should have an extinguishing effect because they disintegrate or disintegrate through the heat of the fire. are split and form various heavy extinguishing gases. In contrast, according to of the present invention, the extinguishing agent consist of sulfur hexafluoride, which is a completely inert gas at normal temperatures. The sulfur hexafluoride has a very high extinguishing ability. It is five times as heavy as the air and As a result, it sinks slightly to the ground and thus holds up well when covering burning areas Objects. In addition, its diffusion speed is in accordance with the higher molecular weight (1q.6) relatively small (0.45 times that of air), so that it is also from this Basically, the fire object is well wrapped up. Furthermore, the remedy is so indifferent such as nitrogen. It hardly reacts at all with other substances, not itself when heated with sodium metal. It is therefore completely non-toxic and therefore different To be preferred to other gases or easily evaporating substances used as extinguishing agents.
