Abstract
Description
Die Erfindung betrifft ein Verfahren und eine Vorrichtung zur Herstellung von depolymerisierter Zellulose, als Vorstufe zur Nitrozellulose, die vor der Nitrierung mit energiereichen Elekt ronen dosiert bestrahlt wird, so daß nach der Nitrierung Schieß baumwolle entsteht, die wiederum durch Verkneten mit Salpeter säureglycerinester und Salpetersäureglykolester Sprenggelatine ergibt.The invention relates to a method and an apparatus for Production of depolymerized cellulose as a precursor to Nitrocellulose, which is nitrated with high-energy elect rons is metered irradiated so that after nitriding shoot cotton is created, which in turn is kneaded with saltpetre acid glycerol ester and nitric acid glycol ester explosive gelatin results.
Der technische Fortschritt der Erfindung manifestiert sich auf fällig dadurch, daß beispielsweise der Polymerisationsgrad der Zellulose (unterschiedliche Viskosität) schon vor der Nitrierung von der Dosis der Elektronenbestrahlung bestimmt wird oder vorab Einstellungen möglich werden.The technical progress of the invention manifests itself on due in that, for example, the degree of polymerization of the Cellulose (different viscosity) even before nitriding is determined by the dose of electron radiation or in advance Settings become possible.
Der Stand der Technik wird verfahrensgemäß durch die beschriebene Maßnahme, also die gefahrlose Einstellung der Viskosität der Zellulose vor der Nitrierung wesentlich verbessert, in den als Folge der dosierten, energiereichen Elektronenbestrahlung die Zellulose depolymerisiert, die Molekülketten also gekürzt werden und dadurch eine molekulare Veränderung eintritt. Als weitere Folge dieser Modefizierungen werden bei der Weiterverarbeitung zu Sprengstoffen Rohstoffeinsparungen offenbar, die gleichzeitig Entsorgungserleichterungen und dadurch auch wirtschaftliche Vor teile bringen.According to the method, the prior art is described by the Measure, ie the safe setting of the viscosity of the Cellulose improved significantly before nitriding, in the than As a result of the metered, high-energy electron radiation Cellulose depolymerized, so the molecular chains are shortened and thereby a molecular change occurs. As another As a result of these modifications, further processing becomes too Explosives resource savings apparently, the same time Facilitation of disposal and thereby also economic advantages bring parts.
Weitaus wichtiger ist die qualitätsbezogene, positive Veränderung der Zellstoffstrukturen und die von der Bestrahlungsdosis ab hängige molekulare Polarität. Es zeigt sich, daß insbesondere bei Anwesenheit von Ammoniakmolekülen kleinster Anzahl, sie sind elektrische Dipole und gegenüber Wassermolekülen Protonakzep toren, sich gewisse molekulare Abhängigkeitsverhältnisse erkenn bar machen, die bei Zündung der fertigen Sprenggelatine offen sichtlich aber beschleunigend zeigen.The quality-related, positive change is far more important of the pulp structures and that of the radiation dose dependent molecular polarity. It turns out that in particular Presence of the smallest number of ammonia molecules, they are electrical dipoles and proton acceptance towards water molecules goals, recognize certain molecular relationships of dependency make bar open when the finished explosive gelatin is ignited show clearly but accelerating.
Es ist ein Verfahrensvorteil, daß bei der Herstellung von Spreng gelatine oder anderen Explosivstoffen auf Nitrozellulosebasis, schon frühzeitig und kontrollierbar Einfluß auf wichtige Vor stufen der Herstellung möglich sind, wobei die Anpassbarkeit des Verfahrens an unterschiedliche Mischvarianten der jeweiligen Zu satzstoffe einen besonderen Stellenwert einnimmt.It is a process advantage that in the manufacture of explosives gelatin or other explosives based on nitrocellulose, early and controllable influence on important tasks stages of production are possible, the adaptability of the Process to different mixed variants of the respective Zu substitutes are of particular importance.
Weitere Versuche sollen zeigen, inwieweit energiereiche, sorg fältig dosierte Elektronenbestrahlung geeignet ist, schon die Vorstufen der Sprengstoffherstellung günstig zu beeinflussen. Das betrifft vorrangig die Behandlung der Additive und Rohstoffe. Grundsätzlich gilt, effektiver bei Gebrauch, sicherer bei der Handhabung und Rohstoff sparend bei der Herstellung, immer unter Berücksichtigung wirtschaftlicher Entsorgung.Further trials should show the extent to which high-energy, dosed electron radiation is suitable, even that To influence the preliminary stages of explosives production favorably. The primarily concerns the treatment of additives and raw materials. Basically, more effective when used, safer when using Handling and raw material saving in production, always under Consideration of economical disposal.
In einem Ausführungsbeispiel wird durch Elektronenbestrahlung aktivierte Zellulose so depolymerisiert, bis ein Viskositätsgrad erreicht ist, der bei angesetzter Nitrierung keine Schießbaum wolle ergibt, sondern bei Hinzufügung der bereits erwähnten Chemikalien direkt Sprenggelatine oder noch zu entwickelnde Sprengstoffe.In one embodiment, by electron radiation activated cellulose depolymerized until a degree of viscosity is reached, no shooting boom when nitriding is applied wool results, but with the addition of those already mentioned Chemicals directly explosive gelatin or still to be developed Explosives.
