Description
Aus pflanzlichen Faserstoffen bestehende Füllmasse für Acetylenflaschen Als Dissousgasbehälter pflegt man Stahlflaschen zu verwenden, die mit einer porösen Masse gefüllt sind, welche die als Absorptionsmittel dienenden Ketone aufsaugt. Diese Füllmasse besteht meist aus einer Mischung von Zement und Kieselgur. Es ist aber auch schon vorgeschlagen worden, für diesen Zweck Bimsstein, Sägespäne, Wolle, Lederabfälle oder Aktivkohle bzw. auch Zellstoff, d. h. aufgeschlossene pflanzliche Faserstoffe zu benutzen.Filling compound for acetylene bottles made from vegetable fibers Steel bottles with a porous one are usually used as a dissolving gas container Mass are filled, which soaks up the ketones serving as absorbents. This filling compound usually consists of a mixture of cement and diatomaceous earth. It is but also has already been suggested for this purpose pumice stone, sawdust, wool, Leather waste or activated carbon or pulp, d. H. open-minded herbal To use fiber.
Die Verwendung pflanzlicher Stoffe als Füllmasse bietet den Vorteil, daß man bei sehr geringem Füllgewicht infolge der Quellfähigkeit dieser Stoffe eine große Lösungsmittelmenge unterbringen kann und die Sicherheit besitzt, daß die quellende Füllnasse auch die letzten, beim Einbringen etwa verbliebenen Hohlräume ausfüllt. Auf der anderen Seite müssen derartige Stoffe jedoch aus .Sicherheitsgründen vor dem Einfüllen mit Flammschutzmitteln imprägniert werden und man hat zu diesem Zwecke z. B. bereits vorgeschlagen, sie durch Behandlung mit Wasserglas einer Verkieselung zu unterwerfen.The use of vegetable substances as a filler has the advantage of that you have a very low filling weight due to the swellability of these substances Can accommodate large amounts of solvent and has the security that the swelling The filling wet also fills the last remaining cavities when it was introduced. On the other hand, however, such substances must be used for safety reasons the filling are impregnated with flame retardants and one has for this purpose z. B. already proposed to silicify it by treatment with water glass to subjugate.
Nach der Erfindung werden als Füllmasse pflanzliche Faserstoffe verwendet, die unter Erhaltung ihrer Faserstruktur aufgeschlossen und iri Cellulosederivate überführt sind, welche wie z. B. die Celluloseäther und Celluloseester, insbesondere die Cellulosexantogenate, in Ketonen unlöslich bleiben. Es erübrigt sich dann die Behandlung mit Flammschutzmitteln, durch die bekanntlich außer einer merklichen Gewichtserhöhung stets eine verminderte Quellfähigkeit der Füllmasse hervorgerufen wird, während sich die Entflammbarkeit mindestens in gleichem Maße verringert. Es entsteht also ein Sicherheitsgasbehälter, der bei vermindertem Gewicht eine erhöhte Aufnahmefähigkeit für Dissousgas besitzt.According to the invention, vegetable fibers are used as filling material, which are opened while maintaining their fiber structure and iri cellulose derivatives are transferred, which such. B. the cellulose ethers and cellulose esters, in particular the cellulose xantogenates, remain insoluble in ketones. It is then superfluous Treatment with flame retardants, which is known to except one noticeable Weight increase a reduced swellability of the filling compound is always caused, while the flammability is reduced at least to the same extent. So it arises a safety gas container, which has an increased capacity with a reduced weight for dissous gas owns.
