Auf Wasser schwimmendes Granulat aus einem geschlossenporigen Schaumstoff mit hoher Bindungsfähigkeit für auf der Wasseroberfläche schwimmende Öle und ölähnliche SchadstoffflüssigkeitenGranules floating on water made of a closed-cell foam with high binding capacity for oils and oil-like pollutant liquids floating on the water surface
Gegenstand der Erfindung ist ein Stoff zur Verwendung als Aufnahmemittel für Öl und ölähnliche Flüssigkeiten, die infolge Tanker- oder Pipelinehavarien oder durch andere Ereignisse in das Wasser gelangen und zu entfernen sind, genannt Ölbinder „Öl-Ex".The invention relates to a substance for use as an absorber for oil and oil-like liquids that enter the water as a result of tanker or pipeline accidents or other events and that need to be removed, called oil binder "Öl-Ex".
Die Erfindung beinhaltet die Bindung von Öl und ölähnlichen Stoffen an die sehr große Oberfläche von Schaumstoffgranulat wie beispielsweise aus geschäumtem Polyurethan aufgrund der Oberflächenkräfte.The invention involves the binding of oil and oil-like substances to the very large surface of foam granules such as foamed polyurethane due to surface forces.
Zu den Merkmalen der Erfindung gehört, daß das Granulat durch einen Brech- und Mahlvorgang geschäumter größerer Blöcke gewonnen wird, wodurch die spezifische Gestalt des Granulats mit einer großen äußeren Oberfläche entsteht, die die Voraussetzung seiner Ölaufnahmeeignung ist. Das Granulat ist aufgrund seiner inneren Geschlossenporigkeit schwimmfähig und behält die Schwimmfähigkeit auch bei Anlagerung großer Mengen des gebundenen Schadöles bei, da die inneren Poren nicht gefüllt werden.One of the features of the invention is that the granulate is obtained by breaking and grinding foamed larger blocks, which creates the specific shape of the granulate with a large external surface, which is the prerequisite for its ability to absorb oil. The granulate is buoyant due to its internal closed pores and retains its buoyancy even when large amounts of bound harmful oil accumulate, since the internal pores are not filled.
Eine chemische Verbindung mit dem Granulat oder eine Auflösung durch Schadöle findet im Havariezeitraum nicht statt.A chemical bond with the granulate or dissolution by harmful oils does not occur during the accident period.
Aufgrund der Bindungsfähigeit des Granulats kann es auch zur Öl- und Kraftstoffbindung im Erdreich eingesetzt werden.Due to the binding ability of the granulate, it can also be used to bind oil and fuel in the soil.
Der Ölbinder wird nachstehend an einem möglichen Beispiel beschrieben:
Granulat aus geschäumte Polyurethan der Dichte von ca. 40 kg/m3 wird zu einer
Korngröße von ca. 3 bis 8 mm so zerkleinert, daß die inneren Poren nicht zusammengedrückt werden und geschlossen bleiben. In dieser Form kann ein
Granulatkorn bis zur 10-fachen Menge seines Eigengewichtes an schwimmendem Öl auf einer Wasseroberfache binden. Infolge der erhalten bleibenden
Schwimmfähigkeit kann dann das Granulat durch einfache mechanische Mittel von der Wasseroberfläche entfernt werden. Eine solche einfache Möglichkeit besteht
auch darin, daß das Granulat in längliche netzartige Hüllen gefüllt wird und als
schwimmende Barrieren einen Havariebereich umschließen.The oil binder is described below using a possible example:
Granules made of foamed polyurethane with a density of approx. 40 kg/m 3 are crushed to a grain size of approx. 3 to 8 mm in such a way that the inner pores are not compressed and remain closed. In this form, a granule can bind up to 10 times its own weight in floating oil on the surface of the water. As the granules retain their buoyancy, they can then be removed from the water surface by simple mechanical means. One such simple possibility is to fill the granules into long, net-like casings and enclose an accident area as floating barriers.
