Description
Verfahren zur Herstellung eines Mittels zur Adsorption von Oelen und verwandten Flüssigkeiten, sowie nach diesem Verfahren hergestelltes Erzeugnis.Process for the preparation of an agent for adsorbing oils and related liquids, as well as product manufactured by this process.
Die vorliegende Erfindung bezieht sich auf ein Verfahren zur Herstellung eines Mittels zur Ausoprtion von Oelen und verwandten Flüssigkeiten, sowie auf ein nach diesem Verfahren hergestelltes Erzeugnis. flach dem erfindungsgemässen Verfahren wird blähbarer Kunststoff geschäumt, wonach die so erhaltenen Schaumstoffkörper zu Schüttgut verarbeitet werden. Das so erhaltene Schüttgut eignet sich vorzüglich zur Reinigung von oelverschmutzten Böden und Gegenständen, insbesondere zur Reinigung von oelverschmutzten ruhenden oder bewegten Gewässern.The present invention relates to a method of manufacture a means for Ausoprtion of oils and related liquids, as well as a Product manufactured according to this process. flat to the method according to the invention expandable plastic is foamed, after which the foam body obtained in this way can be processed into bulk goods. The bulk material obtained in this way is eminently suitable for cleaning oily floors and objects, especially for cleaning from oil-polluted static or moving waters.
Es ist zwar bekannt, zur Reinigung von oelverschmutzten Gewässern Torf oder chemisch nachbehandeltes wasserhaltiges Gerste in glas von mehl- bis griesförmiger Struktur zu verwenden. Diesen Substanzen gegenüber hat das nach dem erfindungsgemässen Verw fahren gewonnene Fasergut jedoch den Vorteil, dass es schon von Haus aus ausgesprochen hydrophob und stark oleophil, und zudem bedeutend leichter ist, und damit in Flssigkeiten einen weit stärkeren Auftrieb besitzt, so dass es ohne chemische Nachbehandlung in weitestem Rahmen als Schwimmträgerkörper einsetzbar ist. Ein weiterer sehr wesentlicher Vorteil des erfindungsgemässen Schüttgutes ist sodann in dem Umstand zu erb licken, dass es samt den adsorbierten oeligen Flüssigkeiten praktisch rückstandfrei verbrennt und zur Gewährleistung einer nuten Verbrennung nicht erst mit zusätzlichem Brennstoff angereichert werden muss. Das erfindungsgemässe Schüttgut ist ausserdem sauber in der Anwendung, biologisch einwandfrei und unbegrenzt lagerbar.It is known to purify oil-polluted waters Peat or chemically treated water-containing barley in Glass to use from flour to gritty structure. Has to face these substances the fiber material obtained by the process according to the invention, however, has the advantage that it is inherently extremely hydrophobic and strongly oleophilic, and moreover is significantly lighter, and therefore a far greater buoyancy in liquids possesses, so that it can be used as a floating support body to the greatest possible extent without chemical aftertreatment can be used. Another very important advantage of the bulk material according to the invention is then to be seen in the fact that it together with the adsorbed oily liquids Burns practically residue-free and ensures a smooth combustion does not have to be enriched with additional fuel. The inventive Bulk material is also clean to use, biologically sound and unlimited storable.
Das Schüttgut wird zweckmässig mit Hilfe von säge- oder raffelartigen Werkzeugen von den geblähten Schaumstoffkörpern abgespant oder durch Mahlen oder Zerstampfen der Schaumstoffkörper gewonnen, wonach es zweckmässig noch mit Substanzen angereichert werden kann, die den Aufsaug- und Bindevorgang beschleunigen, einleiten oder verbessern. Zu diesem Zweck kann das Schüttgut geliert bzw. beispielsweise mit einer Ammonium-Verbindung behandelt werden.The bulk material is expediently with the help of saw-like or grater-like Tools chipped from the expanded foam bodies or by grinding or Crushing the foam body won, after which it is expedient with substances can be enriched, which accelerate the absorption and binding process, initiate or improve. For this purpose, the bulk material can gel or, for example treated with an ammonium compound.
Durch das Mahlen, Zerstampfen oder Zerspanen der Schaumstoffkörper wird nicht nur deren wirksame Oberfläche um ein Vielfaches vergrössert, sondern es werden die Schaumstoffzellen geöffnet, so dass sie als Kapillaren wirken, wodurch das Adsorptionsvermögen zusätzlich noch ganz beträchtlich verstärkt wird.By grinding, crushing or machining the foam bodies its effective surface is not only enlarged many times over, but the foam cells are opened so that they act as capillaries, whereby the adsorptive capacity is also increased considerably.
Zur Gewinnung des Schütt- bzw. Fasergutes eignet sich beispielsweise schäumbares Polystyrol, PVC-Schaum, Phenolharzschäume, schäumbare Harnstoffe und Polyurethan etc., insbesonderte aber der unter der-eingetragenen Schutzmarke WANNERIT bekannte Kunstschaumstoff.For the extraction of the bulk or fiber material is suitable, for example foamable polystyrene, PVC foam, phenolic resin foams, foamable ureas and Polyurethane etc., but especially under the registered trademark WANNERIT well-known synthetic foam.
Das wie beschrieben gewonnene Schütt- bzw. Fasergut wird einfach auf die oelverschmutzten Gegenstände bzw. auf das oelverschmutzte Wasser gestreut, wobei Oel und oeliger Schmutz sofort adsorbiert werden und - bei Masserverschmutzung - z.B. mit Schöpfnetzen abgeschöpft, und samt dem Oelen und Schmutzträger verbrannt werden können.The bulk or fiber material obtained as described is simply on the oil-contaminated objects or sprinkled on the oil-contaminated water, whereby Oil and oily dirt are adsorbed immediately and - in the case of mass contamination - e.g. skimmed off with scooping nets and burned together with the oils and dirt carriers can be.
Die Anwendung derartigen Schütt- oder Fasergutes bleibt indessen nicht auf die Behebung bereits eingetretener Verschmutzungen beschränkt. Es ist im Gegenteil möglicli, das Kunstschaumstoff-Schütt- oder Fasergut auch vorbeugend zu verwenden. So z.B. ist es zweckmässig, Heizoeltanks nicht unmittelbar in das Erdreich, sondern in ein Sunstschaum-Schüttgut-bzw. Faserstoffbett-zu verlegen.However, the use of such bulk or fiber material does not remain limited to the removal of dirt that has already occurred. It is quite the opposite it is possible to use the synthetic foam bulk or fiber material as a preventive measure. For example, it is advisable not to put heating oil tanks directly in the ground, but instead in a Sunstschaum bulk material or. Fiber bed to be laid.
Es ist aber auch möglich, das Schüttgut mit Hilfe eines Bindemittels zu Folien locker zusammengefügten Platten, Bänder oder dgl. zu verarbeiten, und, statt des Schüttgutes, diese Folien, Platten oder Bänder etc. zur Adsorption auszulegen.But it is also possible to use a binding agent for the bulk material to process loosely assembled sheets, tapes or the like into foils, and, Instead of the bulk material, these foils, plates or tapes etc. should be designed for adsorption.
