Description

Verfahren zur Herstellung von Sicherheitszündschnüren. Die bisherige Art, den Pulverkern der Zündschnüre gegen äußere Einflüsse zu schützen, bestand in einer Abdichtung der porösen Gespinstfasern durch Pech, destillierten Teer, Kautschuk, Guttapercha, Leim und deren Kompositionen. Ein dauernder Schutz wurde jedoch durch die genannten Stoffe nicht erreicht, da dieselben der allmählichen Austrozknung oder der Verhärtung infolge von Oxydation durch den Luftsauerstoff unterworfen sind.Process for the manufacture of safety fuses. The previous Way of protecting the powder core of the fuses against external influences existed in a seal of the porous web fibers by pitch, distilled tar, rubber, Gutta-percha, glue and their compositions. A permanent protection was however by the substances mentioned are not reached, since they are gradually drying out or are subject to hardening as a result of oxidation by the oxygen in the air.

Zur Vermeidung der Übelstände, welche die Verwendung der bisher üblichen überzugsmasse zeigte, hat man versucht, dem Ziel durch Imprägnierung des Gespinstes mit nitrierten Ölen n,äherzukommen. Da das Vorhandensein von Öl die Brenndauer der Schnüre ungünstig beeinflußt, sind nennenswerte Erfolge nicht erreicht worden.To avoid the evils which the use of the previously usual coating mass showed, attempts have been made to achieve the goal by impregnating the web with nitrated oils n to come closer. Since the presence of oil increases the burning time of the Cords adversely affected, no noteworthy successes have been achieved.

Bei der vorliegenden Erfindung werden die aus beliebigen Gespinsten oder Papier hergestellten Schnüre mit farblosen oder gefärbten Schichten aus Azetylzellulose, z. B. Zellon, oder ölfreier Nitrozellulose, z. B. Zelluloid, oder deren Ersatzstoffen und Mischungen versehen. ZVährend bei Verwendung der Azetylzellulose als Isolationsmaterial in der Elektrotechnik der Hauptwert auf hohes Isolationsvermögen, große Durchschlags- und Wärmefestigkeit gelegt wird, nutzt die vorliegende Erfindung die Eigenschaft dieses Materials der Wasserdichtigkeit und geringen Alterung durch Oxydation aus.In the present invention, they are made of random webs or paper made cords with colorless or colored layers of acetyl cellulose, z. B. Zellon, or oil-free nitrocellulose, e.g. B. celluloid, or their substitutes and mixes. While using acetyl cellulose as insulation material In electrical engineering, the main value is high insulation properties, large breakdown and heat resistance is placed, the present invention utilizes the property this material is waterproof and has a low aging rate due to oxidation.

Die Überzüge, welche durch Beimengung von mineralischen Stoffen und Metallsalzen unverbrennbar gemacht werden können, bieten dauernde Gewähr für Biegsamkeit der Schutzhülle und Widerstandsfähigkeit derselben gegen Wasser, Fett, Öl, Säuren und Laugen.The coatings, which by adding mineral substances and Metal salts can be made incombustible, offer permanent flexibility the protective cover and its resistance to water, grease, oil and acids and alkalis.
