Abstract

Production of water absorbing and damming body comprises mixing a liquid permeable shell and a hygroscopic mixture comprising a coarse support and a smaller amount of finely divided polymer absorber granules and an adhesive aerosol. Production of water absorbing and damming body containing an adhesive material comprises mixing a liquid permeable shell and a hygroscopic mixture comprising a coarse support and a smaller amount of finely divided polymer absorber granules and introducing an aerosol. An Independent claim is included for the apparatus used where the fill volume is approximately 1/5.

Description

Die Erfindung betrifft ein Verfahren und eine Vorrichtung zum Herstellen von Auf­ saug- und Eindämmkörpern für Wasser.The invention relates to a method and an apparatus for producing Auf absorbent and containment bodies for water.

Wenn in einem Raum wertvolle Gegenstände, z. B. Computer oder Möbel, lagern, die durch einen Wassereinbruch, z. B. bei einem Wasserrohrbruch oder bei einer Überschwemmung, zerstört würden, ist es notwendig, eine effektive und rasche Eindämmung der heranfließenden Wassermengen und gleichzeitig auch ein rasches Aufsaugen von Wasser auf dem Boden durchzuführen, um einen großen Schaden zu verhindern.If valuable objects, e.g. B. store computer or furniture, caused by water ingress, e.g. B. in a broken water pipe or in a Flooding, would be destroyed, it is necessary to be effective and rapid Containment of the incoming water and at the same time a quick one Absorb water on the floor to do great damage prevent.

Aus der OS DE 198 18 102 A1 ist ein Aufsaug- und Eindämmkörper für Wasser und andere nicht säurehaltige Flüssigkeiten bekannt, bei welchem in einer flächigen Hülle eine hygroskopische Mischung aus einem größeren Anteil eines grobkör­ nigen, saugfähigen Trägermaterials und einem kleineren Anteil eines feinkörnigen, stark saugfähigen, polymeren Absorbergranulats untergebracht ist, welches in der Lage ist, ein Vielfaches seines Eigengewichtes an Flüssigkeit aufzunehmen, wobei das pulverartige Absorbergranulat stark aufquillt und gallertartig wird.From OS DE 198 18 102 A1 an absorbent and containment body for water and other non-acidic liquids known, in which in a flat Envelop a hygroscopic mixture of a larger proportion of a coarse some absorbent carrier material and a smaller proportion of a fine-grained, highly absorbent, polymeric absorber granulate is housed, which in the Is able to absorb a multiple of its own weight in liquid, whereby the powdery absorber granules swell strongly and become gelatinous.

Nachteilig hierbei ist jedoch, daß es beim Transport und bei der Lagerung in der flächigen Hülle zu einer Entmischung der beiden Mischungsanteile der hygros­ kopischen Mischung, nämlich des grobkörnigen, saugfähigen Trägermaterials und des wesentlich feinkörnigeren, stark saugfähigen Absorbergranulats, kommt, so daß beim Auslegen der Hüllen zur Eindämmung heranfließender Wassermengen das hochwirksame, stark saugfähige Absorbergranulat nicht mehr gleichmäßig verteilt ist, sondern nur z. B. in einer Ecke der Hülle liegt und nur dort wirkt.The disadvantage here, however, is that it is in the transport and storage in the flat shell to separate the two hygros copical mixture, namely the coarse-grained, absorbent carrier material and of the much more fine-grained, highly absorbent absorber granules, so that when laying out the casings to contain inflowing amounts of water highly effective, highly absorbent absorber granules no longer evenly distributed is, but only z. B. lies in a corner of the envelope and only acts there.

Eine gleichmäßige Vergrößerung einer Hülle durch das Aufsaugen des Wassers im gesamten Inneren der Hülle tritt also bei entmischten Anteilen nicht ein.A uniform enlargement of a shell by absorbing the water in the the entire interior of the envelope does not occur with segregated portions.

Der Erfindung liegt die Aufgabe zugrunde, einen Aufsaug- und Eindämmkörper für Wasser zu schaffen, in dessen Hülle die hygroskopische Mischung eine homogene Verteilung beibehält, auch nach Transport und Lagerung.The invention is based, an absorbent and containment for To create water, in the shell of which the hygroscopic mixture is homogeneous Distribution persists even after transportation and storage.

Gelöst wird diese Aufgabe nach dem erfindungsgemäßen Verfahren dadurch, daß beide Anteile in einen Trommelmischer eingegeben werden und in den Trommel­ mischer ein Aerosol eingeblasen wird, das eine klebrige Substanz enthält. This object is achieved by the method according to the invention in that Both portions are entered into a drum mixer and into the drum an aerosol containing a sticky substance is blown into the mixer.  

Bei einem anderen Verfahren wird jeder Anteil in einem eigenen Druckluftstrom bewegt und zu einem gemeinsamen Druckluftstrom zusammengeführt, in den soviel einer klebrigen Substanz hineingesprüht wird, daß einzelne oder einige Körner der beiden Anteile dauerhaft miteinander verkleben.In another method, each part is in its own compressed air stream moved and merged into a common stream of compressed air, in that much a sticky substance is sprayed in that individual or some grains of the permanently glue both parts together.

Zweckmäßigerweise enthält das Aerosol eine Wasser/Zucker-Lösung, die etwa aus 5 l Wasser und etwa 3 kg Zucker besteht.The aerosol expediently contains a water / sugar solution, which consists approximately of 5 l of water and about 3 kg of sugar.

Vorteilhafterweise wird das Aerosol etwa in einer Menge von 1,5 l einer Menge der Mischung der Anteile von etwa 13,5 kg zugeführt.The aerosol is advantageously used in an amount of approximately 1.5 l fed the mixture of the portions of about 13.5 kg.

Eine Vorrichtung für das Verfahren ist dadurch gekennzeichnet, daß die hygrosko­ pische Mischung aus einem größeren Anteil - etwa 4/5 - eines organischen, grob­ körnigen, saugfähigen Trägermaterials und einem kleineren Anteil - etwa 1/5 - ei­ nes feinkörnigen, stark saugfähigen und in wenigen Minuten quellfähigen polyme­ ren Absorbergranulats besteht.A device for the method is characterized in that the hygrosko Mixture of a larger portion - about 4/5 - of an organic, coarse granular, absorbent carrier material and a smaller proportion - about 1/5 - egg nes fine-grained, highly absorbent and swellable in a few minutes ren absorber granules.

Zweckmäßigerweise beträgt die Füllmenge etwa 1/5 des Rauminhaltes der Hülle.The filling quantity is expediently about 1/5 of the volume of the casing.

Vorteilhafterweise ist die Hülle durch Innenwände in zahlreiche geschlossene Kammern unterteilt.Advantageously, the shell is closed by numerous inner walls Chambers divided.
