Description

Verfahren zur Herstellung von Isolierplatten bzw. -schalen Es ist bekannt, aus Schlackenwolle, Asbest oder sonstigen Faserstoffen Isolierplatten bzw. Isolierschalen herzustellen. Es ist ferner bekannt, einer Schlackenwollaufschwämmung Mägnesiumsulfat als Verfestigungsmittel zuzusetzen. Hierbei besteht der Nachteil, daß die Fasermasse der Einwirkung von überhitztem. Dampf -unterworfen werden muß, um mechanisch fest zu werden, und außerdem in großen Mengen Bindemittel, wie Wasserglas oder Natriumsilicat, notwendig sind. Es ist weiterhin bekannt, organischen Klebstoffen, wie Leim und Stärke, Mineralwolle zuzusetzen und zur Verfestigung des Klebmittels Aluminiumhydroxyd zu verwenden. Der Nachteil dieses Verfahrens besteht -darin, daß keine gegen Hitze beständigen, hochporösen Platten entstehen.Process for the production of insulating panels or shells It is known to be made of slag wool, asbestos or other fibrous materials, insulation panels or Manufacture insulating shells. It is also known to use a slag wool slurry Add magnesium sulfate as a solidifying agent. The disadvantage here is that the fiber mass of the action of overheated. Must be subjected to steam, to become mechanically strong, and also in large quantities of binders such as water glass or sodium silicate, are necessary. It is also known to use organic adhesives, such as glue and starch, adding mineral wool and solidifying the adhesive Use aluminum hydroxide. The disadvantage of this method is that no heat-resistant, highly porous plates are produced.

Die Erfindung betrifft ein Verfahren zur Herstellung von Isolierplatten bzw. -schalen und besteht darin, daß mineralische Faserstoffe in ein-em Wasserbad geschwämmt, dem Bad Tonbeizen, insbesondere Aluminiumsalze ,und Ammoniak, zugesietzt und anschließend die Faslern einer Trocknung unterworfen werden. Es entstehen hochPorö:sie Schalen bzw. Platten von großer Festigkeit !und geringem Raumgewicht. Da zur Durchführung des Verfahrens keine organischen Zusätze benötigt werden, sind die Platten feuerfest und hierdurcli zur Hitzeisolierung verwendbar. Zweckmäßig wird dem Bad- Aluminiumsulfat und Ammoniak zugesetzt, so daß die Fasern vön sich bildendem Aluminiumhydroxyd umgeben werden, welches, sowohl Tals Schaumbildner als auch als Bindemittel dient, also einerseits die Platte hochporös gestaltet, 'andererseits abier ;auch die einzelnen Fasiern kittet.The invention relates to a method for producing insulating panels or shells and consists in the fact that mineral fibers in a water bath sponged, clay stains, especially aluminum salts and ammonia, added to the bath and then the fibers are subjected to drying. There arise high porö: you Trays or plates of great strength! And low volume weight. Because to carry out No organic additives are required during the process, the panels are fireproof and can therefore be used for heat insulation. The bath aluminum sulfate is expedient and ammonia are added so that the fibers are surrounded by aluminum hydroxide which forms become, which serves both as a foaming agent and as a binder, so on the one hand, the plate is designed to be highly porous, on the other hand, also the individual ones Fibers cement.

Alusführungsbeispiel In deinem Wasserbad wird Schlackenwolle, geschwämmt und dann diesem Bad eine @Lösung von Aluminiumsulfat sowie Amrnoniakwa.'sser zugeleitet. Daraufhin wird die Schlakkenwolle auf einem Sieb, zweckmäßig unter Zuhilfenahme einer Saugvorrichtung, von Wasser befreit rund anschließend im Trockenofen getrocknet. Das sich auf den Fasern bildende Alürniniumhydroxyd dient als Distanzbindemittel für die Fasern, so daß eine feuerfeste, durch Sehwämmung und gelartige Bindestoffe poröse Platte von großer Festigkeiit und einem Raumgewicht von etwa o,2 entsteht, die infolge ihrer Unverbrennbarkeit ans Wärmeäsolierplatte bzw. -schale verwendbar ist. Raumgewicht -und Forosität können durch Veränderung der Züs;atzmeingen zum Bad geregelt werden, wodurch sieh die Zugrabe von Schaumbildern erübrigt.Aluminum execution example In your water bath, slag wool is sponged and then a solution of aluminum sulphate and ammonia is fed to this bath. Thereupon the lank wool on a sieve, conveniently under With the aid of a suction device, the water is then removed in the drying oven dried. The aluminum hydroxide that forms on the fibers serves as a spacer binder for the fibers, so that they are fireproof, through insulation and gel-like binding agents porous plate of great strength and a density of about 0.2 is created, which can be used on the thermal insulation plate or shell due to their incombustibility is. Volume weight and forosity can be changed by changing the addition to the Bath can be regulated, making the addition of foam images unnecessary.
