Description
Zündsatz für elektrische Glüh- und Spaltzünder Als Zündsätze für elektrische Zünder verwendet man u. a. Acetylenkupfer, basische Bleipikrate, die Bleisalze des Mononitroresorzins, das basische Bleisalz des 3, 5-Dinitro-2-hydroxytoluols sowie andere basische Bleisalze von Nitrokörpern.Ignition set for electric glow and gap igniters As ignition sets for electric Detonators are used inter alia. Acetylene copper, basic lead picrates, the lead salts of Mononitroresorzins, the basic lead salt of 3, 5-dinitro-2-hydroxytoluene and other basic lead salts of nitro bodies.
Es wurde gefunden, daß das neutrale Bleisalz der Pikraminsäure als Zusatz in elektrischen Glüh- und Spaltzündern besonders gut geeignet ist und gegenüber den bekannten; Zündsätzen für elektrische Zünder den großen Vorteil besitzt, daß es sich leicht als feinkristallinisches Pulver gewinnen läßt, das sich in den gebräuchlichen Nitrocelluloselösungen in Amylacetat und anderen organischen Lösemitteln besonders gut suspendieren läßt. Ferner ist seine chemische Beständigkeit außerordentlich groß. Es verpufft ohne Heftigkeit mit rußender Flamme. Beim Zusammenschuß einer größeren Anzahl von Zündern, wie dies im Bergbau erforderlich ist, treten bei Strommangel, der meist durch fehlerhafte Kontakte in den Zuleitungen verursacht wird, viel -,weniger leicht Versager ein. Hierdurch werden die Unfallmöglichkeiten im Bergbau weiter heruntergedrückt. Der Energieinhalt des Bleipikramats ist ausreichend und kann durch Beimischung von geeigneten Zusätzen sowohl erhöht als auch vermindert werden. Als' Zusätze kommen in Betracht: Feinverteilte Metalle und Legierungen, wie Aluminium, Magnesium, Zirkon, Silicium, Chrom, Wolfram, Titan, sowie Legierungen, Wie Ferrosilicium, Ferrotitän, Wolframkarbid, neben Sauerstoffträgern, wie Kaliumchlorat, Kaliumperchlorat, Bleisuperoxyd, ' 'Mennige, Bleichromat. Für Spaltzünder setzt man °geeignete Leitmittel, wie Silberpulver oder Graphit, zu. Beispiel i Die Polkörper, die zur Herstellung von elektrischen Brückenzündern verwendet werden, werden in einen Zündsatz getaucht, der aus einer Suspension von neutralem Bleipikramat und einer 3°/oigen Nitrocelluloselösung in Amylacetat besteht. Die gewünschte Dicke des Zündköpfchens kann durch ein-und mehrfaches Tauchen erzielt werden. Diese Zündköpfchen werden bei geeigneter Wahl der Glühbrücke z. B. mit o,2o Amp. nicht und mit o,25 Amp. sicher gezündet.It has been found that the neutral lead salt of picric acid as Addition in electric glow and gap igniters is particularly well suited and opposite the known; Ignition sets for electric detonators has the great advantage that it can easily be obtained as a finely crystalline powder, which can be found in the usual Nitrocellulose solutions in amyl acetate and other organic solvents especially can be suspended well. Furthermore, its chemical resistance is exceptional great. It evaporates without violence with a sooty flame. When merging one larger number of detonators, as is required in mining, occur when there is a lack of electricity, which is mostly caused by faulty contacts in the supply lines, much -, less easily a failure. This increases the chance of accidents in mining depressed. The energy content of the lead picramate is sufficient and can go through Admixture of suitable additives can be increased as well as decreased. As' Additives can be considered: Finely divided metals and alloys, such as aluminum, Magnesium, zirconium, silicon, chromium, tungsten, titanium, as well as alloys such as ferrosilicon, Ferrotitanium, tungsten carbide, in addition to oxygen carriers such as potassium chlorate, potassium perchlorate, Lead peroxide, '' Red lead, lead chromate. Suitable guiding means are used for gap fuses, like silver powder or graphite, too. Example i The polar bodies used to manufacture used by electric bridge igniters are immersed in a primer, that from a suspension of neutral lead picramate and a 3% nitrocellulose solution consists of amyl acetate. The desired thickness of the detonator head can be achieved by means of and multiple dives can be achieved. These detonators are properly chosen the glow bridge z. B. not ignited with 0.25 amps and reliably ignited with 0.25 amps.
Beispiele Die genannten Polkörper werden in einen Satz getaucht, der ioo Teile neutrales Bleipikramat, 2o bis 8o@TeileKaliumperchlorat und &a bis 2o Teile Silicium enthält. Die Suspension kann wie in Beispiel i hergestellt werden.Examples The mentioned polar bodies are immersed in a sentence, the 100 parts neutral lead picramate, 2o to 8o parts potassium perchlorate and & a bis Contains 20 parts of silicon. The suspension can be prepared as in Example i.
Beispiel 3 Die unter Beispiel i und 2. genannten Sätze werden in trockenem Zustand in: die bei Zündern mit losem Satz vorhandenen Pappbehälter eingefüllt, so daß sie mit den Glühbrücken in guter Berührung stehen. Beispiel q.Example 3 The sentences mentioned under example i and 2. are written in dry Condition in: the cardboard containers present with detonators with a loose set filled, so that they are in good contact with the glow bridges. Example q.
ioo Teile neutrales Bleipikramat, 1o bis 3o Teile Silberpuder und' 21o, bis 5o@ Teile Graphit werden in .einer Nitrocelluloselackl@;:isung suspendiert, so daß eine geeignete Tauchkonsistenz vorhanden ist. Die so hergestellte Tauchmasse wird auf Polk@c:rp-er ohne Glühbrücken durch Stauchen aufgebracht. Zur Herstellung von,Spaltzün.dern eignet sich auch der in Beispiel 21 genannte S'atz bei Zbmischung der genannten Leitmittel.100 parts neutral lead picramate, 1o to 3o parts silver powder and ' 21o to 5o parts of graphite are suspended in a nitrocellulose lacquer solution, so that there is a suitable dipping consistency. The dipping compound produced in this way is applied to Polk @ c: rp-er without glow bridges by upsetting. For the production From, Spaltzün.dern, the phrase mentioned in Example 21 is also suitable for mixing of the aforementioned guide means.
