Abstract
Description
Die Erfindung betrifft fein abstufbare Zündsätze für Anzündmittel und Anzündelemente.The invention relates to finely graded primers for igniters and Ignition elements.
Die Wirkung von Anzündmitteln und Anzündelementen wird im wesentlichen von zwei Faktoren bestimmt. Zum einen sollen die Reaktionsprodukte nach Möglichkeit partikelreich sein und diese Partikel möglichst heiß sein, zum anderen muß für die Partikel ein Transportgas bereitgestellt werden, damit die die Treibladung so gut wie möglich durchdringen. Auch das Transportgas soll eine entsprechend hohe Temperatur aufweisen, um die Partikeltemperatur aufrechtzuerhalten. Anzündmittel und Anzündelemente, die einen pyrotechnischen Brennstoff auf der Basis B/KNO3 oder Ti/Ba(NO3)2 oder TiHx/Ba(NO3)2 mit x<1 oder Zr/Ba(NO3)2 und Nitrocellulose enthalten, aber auch Anzündmittel und Anzündelemente, die Zirkon und Kaliumperchlorat enthalten, erfüllen im allgemeinen diese Anforderungen.The effects of igniters and igniters are essentially determined by two factors. On the one hand, the reaction products should be rich in particles where possible and these particles should be as hot as possible, and on the other hand a transport gas must be provided for the particles so that they penetrate the propellant charge as well as possible. The transport gas should also have a correspondingly high temperature in order to maintain the particle temperature. Igniters and igniters containing a pyrotechnic fuel based on B / KNO 3 or Ti / Ba (NO 3 ) 2 or TiH x / Ba (NO 3 ) 2 with x <1 or Zr / Ba (NO 3 ) 2 and nitrocellulose , but also igniters and igniters containing zirconium and potassium perchlorate generally meet these requirements.
Neben diesen grundsätzlichen Leistungsanforderungen sind aber auch andere Eigenschaften, die die Empfindlichkeit und die Sicherheit dieser Anzündmittel und Anzündelemente betreffen, von ganz entscheidender Bedeutung für die Qualität und die Einsetzbarkeit solcher Anzündmittel und Anzündelemente. Diese Eigenschaften, die sogenannten elektrischen Kenndaten sind die Anzündempfindlichkeit (Aze), die Anzündunempfindlichkeit (Azu) und die Anzündverzugszeit (Azvz) der einzelnen Sätze. Hierbei sagt die Anzündunempfindlichkeit etwas über die Sicherheit und die Anzündempfindlichkeit bzw. Anzündverzugszeit etwas über die Zündempfindlichkeit der Zündsätze aus. Bisher sind Zündsätze mit entweder genügend hoher Anzündunempfindlichkeit, dafür aber mit zu hohen Werten für die Anzündempfindlichkeit bzw. die Anzündverzugszeit, d.h. mit zu geringer Zündempfindlichkeit oder Zündsätze mit genügend geringer Anzündempfindlichkeit und Anzündverzugszeit, aber nicht ausreichender Anzündunempfindlichkeit bekannt. In addition to these basic performance requirements, there are also others Properties that affect the sensitivity and safety of these igniters and Ignition elements are of crucial importance for quality and the applicability of such igniters and igniters. These characteristics, the so-called electrical characteristics are the ignition sensitivity (Aze), the Ignition insensitivity (Azu) and the ignition delay time (Azvz) of the individual Sentences. The insensitivity to ignition says something about the safety and the Ignition sensitivity or ignition delay time somewhat above the ignition sensitivity of the primers. So far, primers are either sufficiently high Ignition sensitivity, but with too high values for the Ignition sensitivity or the ignition delay time, i.e. with too little Ignition sensitivity or primers with sufficiently low ignition sensitivity and ignition delay time, but insufficient sensitivity to ignition is known.
Aufgabe der vorliegenden Erfindung war es, Anzündmittel und Anzündelemente, im folgenden kurz Anzündelemente genannt, bereitzustellen, die neben einer ausreichenden Leistung je nach Einsatzzweck fein abstufbare Werte für die Anzündempfindlichkeit und die Anzündunempfindlichkeit aufweisen, ohne daß die Anzündverzugszeit wesentlich beeinträchtigt wird.The object of the present invention was to ignite and ignite elements the following, briefly called igniter elements, to be provided in addition to a sufficient performance depending on the application, finely graduated values for the Ignition sensitivity and the ignition insensitivity without the Ignition delay time is significantly impaired.

Zündsatz, der sogenannte Glühdrahtsatz, verantwortlich für die elektrischen Kenndaten, während der 2. Zündsatz, der sogenannte Leistungssatz, verantwortlich ist für die Leistung. Es wurde überraschenderweise festgestellt, daß zur Erhöhung der Anzündunempfindlichkeit des Glühdrahtsatzes, ohne Beeinträchtigung der Anzündverzugszeit, die Sicherstellung einer hohen Wärmeableitung im Glühdrahtsatz von besonderer Bedeutung ist. Dies wird erfindungsgemäß durch einen Zusatz erreicht, der in der Lage ist, die Wärme abzuleiten. Dieser wärmeableitende Zusatz wird ausgewählt aus Substanzen, die bekanntermaßen Wärme aufnehmen können und dadurch der Umgebung Wärme entziehen. Beispiele für solche Substanzen können anorganischer oder auch organischer Natur sein, wie Metalle, Metallverbindungen oder metallorganische Verbindungen.According to the invention, this object was achieved by providing and Combination of two different primers according to their properties Claims 1 to 12.

The diving process is repeated until the one for the respective Use sufficient amount of glow wire set mixture is applied. For the 1st
Zündsatz haben sich Mengen von 6 bis 10 mg bewährt. Zwischen den einzelnen Tauchgängen wird dem Lösungsmittel Gelegenheit gegeben, abzudunsten. Nach dem Glühdrahtsatz wird in gleicher Weise der Leistungssatz als Hülle um den Glühdrahtsatz aufgebracht. Auch für diesen Satz wird der Tauchgang so oft wiederholt, bis die für den jeweiligen Einsatzzweck ausreichende Menge Leistungssatzmischung aufgebracht ist. Als Zündsatzgewicht für die gesamte Zündpille haben sich 50 bis 100, vorzugsweise 65 bis 85 mg bewährt. Nachdem die Zündpille 24 h getrocknet worden ist, wird die Zündpille noch mit einem 20%igen Lack aus dem jeweiligen Bindemittel überzogen und wiederum 48 h getrocknet.Ignition charges have proven their worth in quantities of 6 to 10 mg.
