Description

Vulkanisierform für Gummiwaren Bei der Benutzung von Vulkanisierformen für Gummiwaren tritt bekanntlich der Übelstand auf, daß der Gummikörper an den inneren Flächen der Form haftenbleibt und daß sich infolgedessen krustenartige Ansätze auf den Formflächen bilden. Diese Ablagerungen sind schwer zu entfernen; dabei wird meist die Form beschädigt, so daß sie vorzeitig unbrauchbar wird.Vulcanizing mold for rubber goods When using vulcanizing molds For rubber goods, as is well known, the disadvantage occurs that the rubber body on the inner Surfaces of the form stick and that, as a result, crust-like approaches form the mold surfaces. These deposits are difficult to remove; thereby will mostly damaged the shape, so that it becomes unusable prematurely.

Diese Nachteile werden dadurch erfolgreich beseitigt, daß man gemäß der Erfindung auf einem an sich bekannten Wassergtasüberzug auf den Innenflächen der Form eine Schicht aus Zuckerlösung anbringt. Der Wasserglasitberzug soll eine haltbare Isolier- und Schutzschicht für die Schicht aus Zuckerlösung bilden.These disadvantages are successfully eliminated by according to of the invention on a per se known water gas coating on the inner surfaces Apply a layer of sugar solution to the mold. The Wasserglasitberzug should be a Form a durable insulating and protective layer for the layer of sugar solution.

Ein Beispiel für die Behandlung der Vulkanisierform ist folgendes: Die gut gesäuberte und erwärmte Form wird mit einer Lösung besprengt oder übersprüht, die aus etwa. 71 Wasserglas handelsüblicher Beschaffenheit und etwa ioo 1 Wasser besteht. Es bildet sich sofort infolge Verdunstung des Wassers eine dünne, feste Isolierschicht. Diese wird dann kurz vor Benutzung der Form reit Zuckerlöung (etwa r kg Zucker auf ioo 1 Wasser) übersprüht.An example of the vulcanization mold treatment is as follows: The well-cleaned and heated mold is sprinkled or sprayed with a solution, which made about. 71 water glass of commercially available quality and about 100 liters of water consists. As a result of evaporation of the water, a thin, solid one forms immediately Insulating layer. This is then just before using the mold, sugar solution (approx r kg of sugar on 100 liters of water).

Es ist zwar schon vorgeschlagen worden, auf die Form Wasserglas oder Zuckerlösung aufzubringen, alyer nicht, wie hier angegeben, als Zwischenschutzschicht. Eine Erneuerung der Wasserglasschutzschicht ist in der Regel nur in längeren Zeitabständen notwendig, während die Zuckerschicht zweckmäßig vor jedesmaliger Benutzung der Form neu aufgebracht wird.Although it has already been suggested to take the form of water glass or Apply sugar solution, but not, as stated here, as an intermediate protective layer. A renewal of the protective waterglass layer is usually only possible at longer intervals necessary, while the sugar layer is useful before each use of the mold is reapplied.

Durch die Erfindung wird eine stets gleichbleibende, saubere Unterschicht für die daraufzubringende Schicht aus Zuckerlösung erhalten. Die mit der Wasserglasschutzschicht versehene Form ist also stets gebrauchsfertig für die Aufbringung des Zuckerüberzuges, der auf der glatten und sauberen Wasserglasunterschicht überdies sehr gut und gleichmäßig haftet.The invention results in an always consistent, clean underlayer obtained for the layer of sugar solution to be applied. The one with the protective layer of water glass the provided form is always ready to use for the application of the sugar coating, the one on the smooth and clean water glass sublayer, moreover, very well and evenly adheres.

Es kommen alle Lösungen zuckerartiger Körper, z. B. Rohrzucker, Rübenzucker, Traubenzucker, Dextrin, Maltose u. dgl., für sich oder in Mischungen untereinander in Betracht.There are all solutions of sugary bodies, z. B. cane sugar, beet sugar, Glucose, dextrin, maltose and the like, on their own or in mixtures with one another into consideration.
