Description

Die Erfindung bezieht sich auf ein Verfahren zur Behand­ lung von Kunststoff-Restmaterial, das metallische und or­ ganische Verunreinigungen enthält, bei dem das Kunststoff- Restmaterial in einer wäßrigen, alkalischen Lösung, deren pH-Wert größer 12 beträgt, gewaschen wird, wobei die me­ tallischen Verunreinigungen unter Wasserstoffbildung auf­ gelöst werden, nach dem Hauptpatent 42 33 600.The invention relates to a method for treatment development of plastic residual material, the metallic and or contains ganic impurities in which the plastic Residual material in an aqueous, alkaline solution, the pH is greater than 12, is washed, the me metallic impurities with hydrogen formation can be solved according to the main patent 42 33 600.

Mittels dieses bekannten Verfahrens zur Behandlung von Kunststoff-Restmaterial wird verhindert, daß sich in einem Baustoff, der als eine Komponente derartiges Kunststoff- Restmaterial enthält, unter Auflösung der metallischen Ver­ unreinigungen gasförmige Wasserstoffe bilden. Durch das Ver­ fahren gemäß dem Hauptpatent 42 33 600 wird diese Wasser­ stoffbildung quasi vorweggenommen, bevor das Kunststoff- Restmaterial zum Bestandteil eines Baustoffs wird.By means of this known method for the treatment of Plastic residual material is prevented from being in one Building material that as a component of such plastic Residual material contains, dissolving the metallic Ver form impurities gaseous hydrogen. By ver drive according to the main patent 42 33 600 this water fabric formation virtually anticipated before the plastic Residual material becomes part of a building material.

Bei diesem bekannten Verfahren ist die Reaktionszeit während des Waschvorgangs in der wäßrigen, alkalischen Lösung bis zur vollständigen Auflösung der metallischen Verunreinigungen vergleichsweise lang.In this known method, the reaction time is during the washing process in the aqueous, alkaline solution until to completely dissolve the metallic impurities comparatively long.

Der Erfindung liegt die Aufgabe zugrunde, das vorstehend ge­ schilderte Verfahren zur Behandlung von Kunststoff-Restma­ terial derart weiterzubilden, daß die Reaktionszeit bis zur vollständigen Auflösung der metallischen Verunreinigungen drastisch verkürzt ist.The invention is based, the above ge outlined procedures for the treatment of plastic residues educate material such that the response time to complete dissolution of metallic contaminants  is drastically shortened.

Diese Aufgabe wird bei dem eingangs genannten Verfahren erfindungsgemäß dadurch gelöst, daß das metallische und organische Verunreinigungen enthaltende Kunststoff-Restmaterial vor dem Waschen zu Kunststoffgranulat verarbeitet, unmittelbar nach seiner Herstellung noch heiß in die Waschlösung eingebracht und der Waschvorgang bei einer Temperatur von 60 bis 90°C durchgeführt wird.This task will in the process mentioned at the beginning solved according to the invention in that the containing metallic and organic contaminants Plastic waste material processed into plastic granulate before washing, still hot immediately after its manufacture introduced into the washing solution and the washing process at one temperature from 60 to 90 ° C is carried out.

Durch Einhaltung des genannten Temperaturbereichs ergibt sich die erhebliche Reduzierung der Reaktionszeit; da der Waschvorgang in der wäßrigen, alkalischen Lösung unmittel­ bar nach demjenigen Verfahrensschritt durchgeführt wird, bei dem das Kunststoff-Restmaterial zu Kunststoffgranulat verarbeitet wird, kann die bei diesem Verarbeitungsschritt entstehende Wärmeenergie, die in Form von Eigenwärme des Kunststoffgranulats auftritt, vorteilhaft genutzt werden. Das Kunststoffgranulat wird im heißen Zustand in die wäß­ rige, alkalische Lösung eingebracht.By observing the specified temperature range the significant reduction in response time; since the Washing process in the aqueous, alkaline solution immediately bar is carried out after that process step, in which the plastic residual material to plastic granulate can be processed in this processing step arising thermal energy, which is in the form of its own heat Plastic granulate occurs, can be used advantageously. The plastic granulate is in the hot state in the aq alkaline solution.
