Description
Verfahren zur Herstellung lagerbeständiger und gegen Streuströme sicherer elektrischer Zünder Die Erfindung betrifft ein Verfahren zur Herstellung von lagerbeständigen und gegen Streuströme sicheren elektrischen Zündern.Process for the production of storage-stable and more secure against stray currents electric igniter The invention relates to a method for the production of storage-stable and electric detonators that are safe against stray currents.
Die bisher verwendeten elektrischen Zünder enthalten als Zündstoff meist Acetylenkupfer. Dieser Stoff zersetzt sich an der freien Luft, und die damit gefertigten Zünder haben infolgedessen nur eine geringe Lagerbeständigkeit. Das Acetylenkupfer hat ferner einen Verpuffungspunkt von 1o8°. Es ist sehr zündempfindlich und galt daher bisher als besondersgeeignet für dieHerstellung vonZündern.The previously used electric detonators contain as an ignition material mostly acetylene copper. This substance decomposes in the open air, and with it Manufactured detonators therefore have only a short shelf life. That Acetylene copper also has a deflagration point of 1o8 °. It is very sensitive to ignition and was therefore considered to be particularly suitable for the production of igniters.
Veranlaßt durch verschiedene Unglücksfälle, sind neue Vorschriften zur Herstellung von Zündern erlassen, nach denen eine besonders hohe Zündempfindlichkeit nicht mehr erwünscht ist. Es sind'bei den verschiedenen Zünderarten daher Vorrichtungen getroffen, um die Zündempfindlichkeit zu verringern. So wurden z. B. starke Glühdrähtchen verwendet oder Vorschaltwiderstände oder Widerstände im Nebenschluß eingeschaltet.Caused by various accidents are new regulations for the manufacture of detonators, according to which a particularly high ignition sensitivity is no longer wanted. There are therefore devices for the various types of detonators taken to reduce the ignition sensitivity. So were z. B. strong filaments used or switched on series resistors or resistors in the shunt.
Erfindungsgemäß wird dieselbe Wirkung, statt durch komplizierte verteuernde Änderungen an den Zündern, dadurch erreicht, daß ein an sich weniger empfindlicher Zündstoff an Stelle des Acetylenkupfers verwendet wird. Als besonders geeignet wurden die Chinolnitrosäuren der hochnitrierten aromatischen Nitrokörper, deren .Salze oder Derivate erkannt. Diese Stoffe eignen sich auch wegen ihrer großen Lagerbeständigkeit und ihrer größeren Sicherheit gegen Streuströme für den vorliegenden Zweck.According to the invention, the same effect is made more expensive instead of complicated Changes to the detonators, achieved by making an intrinsically less sensitive Igniter is used in place of acetylene copper. Have been considered particularly suitable the quinolnitro acids of the highly nitrated aromatic nitro bodies, their salts or derivatives recognized. These substances are also suitable because of their long shelf life and their greater security against stray currents for the present purpose.
