Abstract

Non-toxic composite sheet web for wet biotopes, natural swimming pools and ponds which comprises an upper, non- toxic sheet web of plasticized polyvinyl chloride, which in no way harms the microorganisms in the pond, contains no reclaimed material and only plasticizers which do not harm the pond life, and a lower sheet web of customary corresponding material, in particular as far as increased durability is concerned, which are directly bonded together.

Claims (3)

<Desc/Clms Page number 1> Die Erfindung betrifft eine Verbundfolienbahn aus Kunststoff, insbesondere für Feuchtbiotope, Naturbadeteiche und Teichanlagen, die dadurch gekennzeichnet ist, dass sie aus einer unteren, herkömmlichen Folienbahn in der erforderlichen Dicke und einer zweiten, speziell für Feuchtbiotope geeigneten oberen Folienbahn besteht, welche direkt miteinander verbunden sind. Es ist bekannt, dass Kunststoffolien aus verschiedensten Materialien zur Abdichtung im Teichbau verwendet werden. Überwiegend handelt es sich hier um als Teichfolien deklarierte Bau- oder Dachdeckerfolien, die jedoch aus folgenden Gründen ungeeignet sind.The invention relates to a composite film web made of plastic, in particular for wetlands, natural bathing ponds and pond systems, which is characterized in that it consists of a lower, conventional film web in the required thickness and a second, especially suitable for wetland habitats Foil sheet exists, which are directly connected to each other. It is known that plastic films made of various materials are used for sealing in pond construction. Mostly, these are construction or roofing films declared as pond liners, but are unsuitable for the following reasons. 1. sind diesen Folien wegen Regeneratanteilen schon bei der Erzeugung Pestizide und Fungizide beigegeben, 2. enthalten diese Folien Weichmacher auf Schwermetallbasis (z. B. Blei-, Arsenverbindungen usw.) Erfahrungsgemäss schädigen sowohl die Fungizide und Pestizide als auch die Schwermetalle des Weichmachers in unterschiedlichen aber relativ kurzen Zeiträumen die Mikroorganismen des Teichwassers und bringen das Teichleben zum Absterben.  1. These films are already added to pesticides and fungicides during production due to the proportion of regrind, 2. These films contain plasticizers based on heavy metals (e.g. lead, arsenic compounds, etc.) Experience has shown that both the fungicides and pesticides and the heavy metals of the plasticizer damage the microorganisms in the pond water in different but relatively short periods of time and cause pond life to die. Als geeignet hingegen haben sich regeneratfreie Folien aus Polyvinylchlorid herausgestellt, die keine kalkhaltigen Füllstoffe, keine Schwermetalle, keine Fungizide und Pestizide enthalten und deren Weichmacher z. B. auf Phthalsäureester-Basis beruht.  On the other hand, regenerative-free films made of polyvinyl chloride have been found to be suitable, which contain no calcareous fillers, no heavy metals, no fungicides and pesticides and whose plasticizers, for. B. based on phthalic acid ester. Daraus ergibt sich, dass die untere, mit der Teichmulde in Berührung kommende Schicht aus für den Zweck geeigneten, konventionellen Kunststoffen (z. B. auch PVC) besteht, die obere aber, den Teichboden bildende Deckschicht aus PVC den biologischen Anforderungen des Teichlebens entsprechen muss.  This means that the lower layer that comes into contact with the pond consists of conventional plastics suitable for the purpose (e.g. PVC), but the upper cover layer of PVC that forms the bottom of the pond must meet the biological requirements of pond life . Ein integraler Bestandteil der erfindungsgemässen, zweifarbigen Verbundfolie ist die Zweischichtigkeit aus einer herkömmlichen Kunststoffbahn und einer für das Feuchtbiotop unbedenklichen Schicht mit dazwischenliegender Armierung.  An integral part of the two-tone composite film according to the invention is the two-layer structure consisting of a conventional plastic sheet and a layer which is harmless to the moist biotope with reinforcement in between. PATENTANSPRÜCHE 1. Nicht toxische Verbundfolienbahn, für Feuchtbiotope, Naturschwimmteiche und Teichanlagen, dadurch gekennzeichnet, dass sie aus einer oberen, nicht toxischen, die Mikroorganismen im Teich keinesfalls beeinträchtigenden Folienbahn aus Weich-Polyvinylchlorid, die keine Regenerate und nur Weichmacher enthält, die das Teichleben nicht beeinträchtigen und einer unteren Folienbahn aus entsprechendem herkömmlichem Material, insbesondere was die Haltbarkeit betrifft, besteht, welche direkt miteinander verbunden sind.  PATENT CLAIMS 1. Non-toxic composite film web, for wetlands, natural swimming ponds and pond systems, characterized in that it consists of an upper, non-toxic film web made of soft polyvinyl chloride, which in no way affects the microorganisms in the pond, which contains no regenerates and only plasticizers, which does not improve pond life impair and a lower film web made of appropriate conventional material, especially with regard to durability, which are directly connected to each other. 2. Verbundfolienbahn nach Anspruch 1, dadurch gekennzeichnet, dass die beiden Folienbahnen durch Koextrudieren oder Kalandrieren miteinander verbunden sind. 2. Composite film web according to claim 1, characterized in that the two film webs are connected to one another by coextrusion or calendering. 3. Verbundfolienbahn nach Anspruch 1 oder 2, dadurch gekennzeichnet, dass dazwischen eine Armierung aus Gelegen oder Geweben eingelegt ist. **WARNUNG** Ende CLMS Feld Kannt Anfang DESC uberlappen**. 3. Composite film web according to claim 1 or 2, characterized in that a reinforcement made of scrims or fabrics is inserted between them. ** WARNING ** End of CLMS field knows overlap beginning of DESC **.
