Verfahren zur Herstellung eines metallischen Überzuges auf Dachpappe.
EMI1.1
Dachpappe, bei welchem behufs Erzietung eines dauerhaften Produktes die mit Teer, Petroleumruckständen und dergl. imprägnierte Rohpappe mit einem metallischen Überzug. insbesondere aus Aluminium oder Legierungen des Aluminiums versehen wird.
Die Handel vorkommende Dachpappe, welche sich als Bedachungsmaterial stetig steigender Beliebtheit erfreut, wird durch Tränken bezw. Imprägnieren von Rohpappe mit Teer, Petroleumrückständen und dergl. und nachheriges Hestreuen mit Sand und ähnlichen Materiaiien erzeugt. diese Dachpappe hat unter anderem den grossen Nachteil, dass infolge der atmosphärischen Einflüsse eine Zerstörung, resp. Verwitterung der in ihr enthaltenen organischen Stoffe
EMI1.2
Vornahme von Konservierungsanstrichen innerhabl einer unbegrenzten Zeit unnötig ist, wird beispielsweise durch die Aufbringung eines Überzuges von Aluminium auf die Dach- pappe gelöst.
Dieses Metall ist bekanntlich überaus luftbeständig, da es sich sehr schnell mit einer unsichtbar dünnen und festhaftenden Haut von Aluminium-Oxyd überzieht, welche das darunter liegende Metall wie ein Firnis schützt. Auch die im Rauch enthaltenden Schwefelverbindungen (wie Schwefeldioxyd), die hauptsächlichsten Schädlinge der Dachpappe, üben nicht den geringsten Einfluss auf Aluminium ans.
Eine bevorzugte Ausführugnsform des Verfahrens besteht darin, dass man zunächst rohr Pappe in bekannter Weise imprägniert. hierauf Aulminium in Form eines feinen Pulvers auf die Oberfläche aufträgt und es schliesslich mit Hilfe von Walzen fest in die Pappe eindrückt, wodurch ein kompakter metallischer Überzug erzielt wird.

Process for the production of a metallic coating on roofing felt.
EMI1.1
Roofing felt, in which, in order to provide a permanent product, the raw cardboard impregnated with tar, petroleum residues and the like with a metallic coating. is provided in particular from aluminum or alloys of aluminum.
The trade occurring roofing felt, which enjoys steadily increasing popularity as a roofing material, is resp. Impregnation of raw cardboard with tar, petroleum residues and the like. And then sprinkling with sand and similar materiaiien produced. this roofing felt has, among other things, the major disadvantage that as a result of atmospheric influences a destruction, respectively. Weathering of the organic substances it contains
EMI1.2
It is unnecessary to apply preservative coatings for an unlimited period of time, for example by applying a coating of aluminum to the roofing cardboard.
This metal is known to be extremely air-resistant, as it is very quickly covered with an invisibly thin and firmly adhering skin of aluminum oxide, which protects the underlying metal like a varnish. The sulfur compounds contained in the smoke (such as sulfur dioxide), the main pests of the roofing felt, do not have the slightest influence on aluminum.
A preferred embodiment of the process consists in first impregnating cardboard in a known manner. Aulminium is then applied to the surface in the form of a fine powder and it is finally pressed firmly into the cardboard with the help of rollers, whereby a compact metallic coating is achieved.
