Description

Dichtungsbahn aus Abfallpolyäthylen (PE)Sealing membrane made from waste polyethylene (PE)

Das Verfahren betrifft die Herstellung einer Dichtungsbahn unter Verwendung von Abfall-und Altpolyäthylen.The method relates to the manufacture of a geomembrane using of waste and recycled polyethylene.

Bisher brachte die Verwendung von Alt- oder Abfallpoiyäthylen Risiken mit sich, da insbesondere beim Alt-PE Verschmutzungen, Verwitterungen und Frendteile nicht auszuschließen sind, mit Einschränkungen gilt dieses auch für Abfall-PE. Eine Aufbereitung, d.h.So far, the use of old or waste polyethylene has brought risks with itself, especially with old PE, soiling, weathering and frend parts cannot be ruled out, with some restrictions this also applies to waste PE. One Processing, i.e.

Trennung von Fremdmaterialien ist zum Teil nicht möglich und ansonsten mit zu hohen Kosten verbunden, als daß ein wirtschaftliches Ergebnis erreicht werden kann.Separation of foreign materials is sometimes not possible and otherwise associated with too high costs for an economic result to be achieved can.

Diese Erfindung, von der Voraussetzung aus, daß das Abfall- und Altpolyäthylen wie vorgefunden verwendet wird. Zu diesem Zweck wird eine Trägerfolie in einer Starke von etwa 0,1 bis 0,4 mm aus Neupolyäthylen verwendet, auf die das Altpolyäthylen aufkaschiert wird.This invention, on the assumption that the waste and old polyethylene is used as found. For this purpose, a carrier film is used in a thickness from about 0.1 to 0.4 mm of new polyethylene used, on which the old polyethylene is laminated.

Die absolute Dichtigkeit wird somit durch die Trägerfolie garantiert, die erforderliche Stärke, die genügend Widerstand gegen mechanische Beschädigungen, agressive Angriffe und zur Erreichung der Möglichkeit der Fügetechnik durch die stärkere Beschichtung aus dem Abfall- bzw.Absolute tightness is guaranteed by the carrier film, the required strength, sufficient resistance to mechanical damage, aggressive attacks and to achieve the possibility of joining technology due to the thicker coating from the waste or

Altpolyäthylen. Durch die Möglichkeit der Verwendung des Abfall und Altpolyäthylenes werden erhebliche Rohstoff- und Energiekosten eingespart, die sonst für die Herstellung der Dichtungsbahnen und für die Vernichtung des Alt- und Abfallpolyäthylenes erforderlich wären.Recycled polyethylene. Due to the possibility of using the waste and Recycled polyethylene saves considerable raw material and energy costs that would otherwise for the production of waterproofing membranes and for the destruction of old and waste polyethylene would be required.

Die Verwendung der Dichtungsbahn ist überall dort voraesehen, wo auch derzeit Polyäthylen-Dichtungsbahnen eingesetzt werden. Darüber hinaus in Bereichen, wo die Dichtungsbahnen aus Neupolyäthylen zu kostenträchtig sind, z.B. zum Schutz des Grundwassers gegen Säuren, Laugen, Öle und fette aus Mülldeponien oder zur Abdeckung derartiger Deponien gegen einfließendes Wasser.The use of the waterproofing membrane is envisaged wherever Polyethylene geomembranes are currently used. In addition, in areas where the geomembranes made of new polyethylene are too expensive, e.g. for protection of the groundwater against acids, alkalis, oils and fats from landfills or for covering such landfills against inflowing water.

Claims (2)

Patentansprüche: 1. Die Dichtungsbahn aus Abfallpoluätylen ist dadurch gekennzeichnet, daß Abfall und Altpolyäthylen für die Herstellung von Dichtungsbahnen verwendet wird. Claims: 1. The sealing membrane made of waste polyethylene is thereby characterized that waste and recycled polyethylene for the production of waterproofing membranes is used. 2. Die Dichtungsbahn aus Altpolyäthylen ist nach Anspruch 1. dadurch gekennzeichnet, daß die Bahn zweilagig hergestellt wird aus einer Lage Neupolyäthylen und einer Lage Altpolväthylen bzw. Abfallpolyäthylen.2. The sealing sheet made of recycled polyethylene is characterized according to claim 1. characterized in that the web is made in two layers from one layer of new polyethylene and a layer of old polyethylene or waste polyethylene.
