Description

Füllung für Wärmeisolierungen aus einem faserförmigen und einem staubförmigen Isolierstoff Zusatz zum Patent 402 787 Nach dem Patent 402 787 werden zur Herstellung einer Füllung für Wärmeisolierungen zwei Isolierstoffe miteinander vermischt, die in Wechselwirkung zueinander stehen. Der eine Stoff, z. B. Iiieselgur, ist staubförmig der andere Stoff, z. B. Schlackenwolle, aber faserig. Der staubförmige Stoff neigt für sich allein zum Sacken, was aber der beigemischte faserige Stoff verhindert. Dieser wiederum ist für sich allein nicht hinreichend widerstandsfähig gegen Hitze, gegen die er aber durch den beigemischten staubförmigen Stoff geschützt wird. Auf diese Weise erhält das Gemisch einen sehr hohen Isolierwert, da die Füllung stets locker bleibt, also weder zusammensacken, noch auch durch Hitze versintert oder sonstwie zusammengeschrumpft werden kann.Filling for thermal insulation made of a fibrous and a dust-shaped one Insulating material additive to patent 402 787 According to patent 402 787 are used to manufacture a filling for thermal insulation two insulating materials mixed together, the are in interaction with each other. One substance, e.g. B. Iiieselgur, is dusty the other substance, e.g. B. slag wool, but fibrous. The powdery substance tends on its own to sag, which the added fibrous material prevents. This in turn is not sufficiently resistant to heat on its own, but against which it is protected by the added powdery substance. on In this way, the mixture has a very high insulation value, since the filling is always remains loose, so neither collapses nor sintered by heat or otherwise can be shrunk.

Es ist nahehegend, statt der Schlackenwolle irgendeine keramische Wolle, z. B. Glaswolle, zu verwenden. Diese keramischen Faserstoffe sind aber spröde und werden somit der Gefahr der Zertrümmerung ausgesetzt, wenn sie innig mit dem staubförmigen Isolierstoff, z. B. Kieselgur, vermischt werden sollen. Das wird der Erfindung gemäß dadurch vermieden, daß dem spröden Faserstoff vor oder bei dem Zusatz des staubförmigen Stoffes gebrannte Magnesia beigemischt wird, welche die Eigenschaft hat, sich an die spröde Faser anzuheften, die Stöße und Reibungen bei der Vermischung mit dem staubförmigen Isolierstoff zu mildern und die spröden. Fasern auf diese Weise vor wesentlicher Zertrümmerung zu schützen.It is obvious that instead of slag wool, some ceramic one Wool, e.g. B. glass wool to use. However, these ceramic fibers are brittle and are thus exposed to the danger of shattering when intimate with the dusty insulating material, e.g. B. kieselguhr to be mixed. That will be the Invention according to avoided that the brittle pulp before or during the addition burnt magnesia is added to the powdery substance, which has the property has to adhere to the brittle fiber, the shocks and friction during mixing with the dusty insulating material to soften and the brittle. Fibers on this Way to protect from substantial shattering.

PATENTANSPRUCH: Füllung für Wärmeisolierungen aus einem faserförmigen und einem staubförmigen Isolierstoff nach Patent 402787, dadurch gekennzeichnet, daß bei Verwendung eines spröden, faserförmigen Isolierstoffes (z. B. Glaswolle) vor oder bei dem Zusatz des staubförmigen Isolierstoffes (z. B. Kieselgur) gebrannte Magnesia. beigemischt wird, so daß sich beide Isolierstoffe inniger vermischen lassen, ohne daß .eine wesentliche Zertrümmerung des spröden, faserförmigen Isolerstoffis eintritt.PATENT CLAIM: Filling for thermal insulation made of a fibrous and a dust-like insulating material according to patent 402787, characterized in that when a brittle, fibrous insulating material (e.g. glass wool) is used, fired before or when the dusty insulating material (e.g. diatomite) is added Magnesia. is admixed so that the two insulating materials can be mixed more intimately without. a substantial destruction of the brittle, fibrous insulating material occurs.
