Description

ZündernDetonators

In dem Patent 803 645 wird die Beimischung von Stoffen, wie Natriumbicarbonat, Kaliumbromid u. a., zu der Unterladung von Sprengkapseln in Verbindung mit elektrischen Zündern zum Zwecke der Verbesserung der Schlagwettersicherheit geschützt.In the patent 803 645 the admixture of substances such as sodium bicarbonate, potassium bromide inter alia, on the undercharging of detonators in connection with electric detonators Protected for the purpose of improving fire weather security.

Es wurde nun gefunden, daß außer den dort angeführten Stoffen auch Polycarbonsäuren und deren neutrale oder saure Salze, Oxypolycarbonsäuren und deren neutrale oder saure Salze sowie durch Halogen substituierte mehrbasische Carbon- und Oxycarbonsäuren und deren neutrale oder saure Salze sich für den genannten Zweck besonders gut eignen.It has now been found that, in addition to the substances listed there, also polycarboxylic acids and their neutral or acidic salts, oxypolycarboxylic acids and their neutral or acidic salts as well polybasic carboxylic and oxycarboxylic acids substituted by halogen and their neutral or acid salts are particularly suitable for the stated purpose.

Erfindungsgemäß haben sich ferner von den im Hauptpatent genannten Stoffen insbesondere auch beständige Carbonate von organischen Basen, wie Guanidin, als sehr gut geeignet erwiesen, die Schlagwettersicherheit der mit elektrischen Zündern verbundenen Sprengkapseln in hervorragender Weise günstig zu beeinflussen. Die vorbenannten Stoffe kommen für sich allein oder in Mischung miteinander bzw. mit den im Hauptpatent vorgeschlagenen Stoffen, die in Mengen von 1 bisAccording to the invention, the substances named in the main patent have in particular also differed stable carbonates of organic bases, such as guanidine, proved to be very suitable for the Fire-weather protection of the detonators connected to electric detonators in excellent Way to influence favorably. The aforementioned substances come on their own or in a mixture with each other or with the substances proposed in the main patent, which are available in amounts from 1 to

20°/o dem Sekundärsprengstoff beigemischt sind, zur Verwendung.20% are mixed with the secondary explosive for use.
