Description

Verfahren zum Zünden bzw. Initiieren von Sprengstoffen. Sprengstoffe, die eines besonderen Initialimpulses nicht bedürfen, wie z. B. Schwarzpulver, Sprengsalpeter, in flüssigen Sauerstoff getauchte Patronen usw., wurden bisher durch die Stichflamme der Zündschnur oder durch den Funken eines elektrischen Zünders gezündet. Alle anderen Sprengstoffe dagegen, die zu ihrem plötzlichen Zerfall einen Initialimpuls benötigen, wie z. B. Dynamit, Ammonsalpetersprengstoffe usw., werden mit Sprengkapseln initiiert.Process for igniting or initiating explosives. Explosives, which do not require a special initial impulse, such as B. black powder, explosive nitrate, Cartridges immersed in liquid oxygen, etc., were previously used by the jet flame ignited by the fuse or by the spark of an electric detonator. All other Explosives, on the other hand, which require an initial impulse for their sudden disintegration, such as B. dynamite, ammonium nitrate explosives, etc., are initiated with detonators.

Die Erfindung besteht darin, daß man die Umsetzungsgeschwindigkeit der ersterwähnten Sprengstoffe-wesentlich beschleunigt, indem man zur Zündung ein Thermitgemisch verwendet, welches zweckmäßig in eine Hülse eingepreßt wird.The invention consists in that one the conversion rate The first-mentioned explosives - significantly accelerated by going to the ignition Thermit mixture used, which is expediently pressed into a sleeve.

Es hat sich gezeigt, daß man leicht initiierbare Sprengstoffe, beispielsweise Dynamit, in flüssige Luft getauchte Patronen usw., ebenfalls durch die thermische Wirkung des Therrnits initiieren kann, ohne daß die Sprengstoffe in ihrer Leistungsfähigkeit herabgemindert werden. Zweckmäßig wird ein Thermitgemisch in eine Hülse eingepreßt und mit einer Anfeuerung, z. B. Nitrocellulosepulver, Rhodan-Perchlorat-Satz, versehen. Das Thermitgemisch kann beispielsweise nachstehende Zusammensetzung haben: 40 °%o Aluminium, 2o °/o Magnesium, 40'/, Eisenoxyduloxyd. Die Zündung dieser Zündkapseln erfolgt in bekannter Weise mit Zündschnur oder durch den Funken des elektrischen Zünders. Ein wesentlicher Vorteil dieser neuen Zündkapseln besteht darin, daß die Zündkapseln absolut handhabungssicher sind und nicht unter das Sprengstoffgesetz fallen.It has been shown that one can easily initiate explosives, for example Dynamite, cartridges immersed in liquid air, etc., also by the thermal one The effect of the thermite can initiate without affecting the explosives in their efficiency be degraded. A thermite mixture is expediently pressed into a sleeve and with a firing, e.g. B. nitrocellulose powder, Rhodan perchlorate set, provided. The thermite mixture can, for example, have the following composition: 40% o Aluminum, 20 per cent. Magnesium, 40 per cent., Iron oxide. The ignition of these detonators takes place in a known manner with fuse or by the spark of the electric Detonator. A major advantage of these new primers is that the Primers are absolutely safe to use and not subject to the Explosives Act fall.

Im Gegensatz zu den sogenannten Spaltglüh- und Spaltfunkenzündern, die durch elektrisch zum Glühen gebrachte Metallteilchen entzündet `-erden, bezweckt die Erfindung, mittels thermischen Gemisches, welches am zweckmäßigsten in Hülsen eingeprellt wird, den Sprengstoff zu initiieren bzw. zu entzünden. Die Einleitung der Entzündung geschieht hierbei durch Zündschnüre bzw. elektrische Zünder. Die Umsetzung des Sprengstoffes ist auf diese Weise nach der Erfindung zweckmäßig und praktisch erreicht.In contrast to the so-called gap glow and gap spark igniters, which is ignited by metal particles made to glow electrically, is intended the invention, by means of thermal mixture, which is most convenient in pods is bounced to initiate or ignite the explosive. The introduction the ignition takes place here by fuses or electric detonators. the Implementation of the explosive is expedient and in this way according to the invention practically achieved.
