    A floor covering contains, in bulk, a polymeric material present in the form of usable granules, the usable granules being produced by a comminution process from material initially present in raw granules. In order to avoid the use of old cable material and the remnants of copper strands present therein and to use alternative waste materials instead, it is proposed; that the material in its pure form folds in a rinsing process of an extrusion device for the production of sheathed cables.

    Riding arena floor
    description
    introduction
    The invention relates to a floor covering which contains a present in bulk in Cebrauchskörnung material, wherein the Nutzskörnung is prepared by a crushing process from initially present in a Rohkörnung material.
    In addition, the invention relates to the use of a present in bulk in granular material used as flooring, wherein the Nutzskörnung is prepared by a crushing process from initially present in a Rohkörnung material.
    State of the art
    • G
    Floor coverings consisting of polymeric materials in consumer granules, which are considered loose bulk occurrences, are well known. As a footing for Reitplatzbeläge they have significant advantages compared to sand, which is commonly used as flooring. So it comes to the annoyance of dust due to the larger grain size in dry weather. In addition, it is advantageous for the outdoor use that the space remains usable even in wet conditions in conjunction with a suitable drainage, since the polymer particles, in contrast to the fine sand grains, do not absorb water. Thus, the polymeric flooring does not freeze even at cold temperatures and remains available year round.
    As a starting material for the production of such Nutzkörörnung as flooring usually cable residues are used. For example, Prof. Gert Bischoff from the University of Applied Sciences Erfurt, Department of Landscape Architecture, reported at the annual meeting of the Society for Plastics in Agriculture (GKL) on 02./03.05.2005 in his lecture "Use of plastic materials in the construction of riding arenas" (http: // //ktbl-alt.avenit.de/gkl/tagung2006/Bischoff.pdf) on the use of cable scraps as a footing for riding arenas.
    Furthermore, the 2005/12/22 2005/07/0088 of the Austrian Administrative Court (VwGH) refers to a riding surface covering made of cable granules, which is "pure waste of electrical cables", "remnants of copper material "Which can be" estimated at 5 - 10% of the volume ".
    - These statements make it clear that the recycling of old cables has disadvantages. The always necessary separation of the metallic conductor from the surrounding polymeric insulation material does not always succeed perfectly. Metallic contamination of the resulting cable granules can not be avoided. This poses a danger to humans and animals, because the fine metal splinters can lead to injuries. (See "Copper Wires in the Eye" from http://www.ich-habe-ein-pferd.com/forums/thread/6081 91 .aspx 28.08.06). Likewise, the recoverable grain sizes for use graining in the recovery of old cables are limited upwards depending on how thick the sheaths of the present cables are. Also, the geometry of the producible particles is limited due to the "tube shape" of the starting material.
    task
    The invention has for its object to propose a floor covering in bulk from polymeric material, which is free of any metallic contamination and can be produced in any particle sizes and grain geometries.
    solution
    Based on a floor covering of the type described above, the object is achieved in that the material obtained in pure form in a rinsing process of an extrusion device for producing jacketed cable.
    Instead of the complete cable as a starting material for the production of Cebrauchskörnung so pure insulation material is used, as obtained in a rinsing process of an extrusion device for producing jacketed cable. When changing the color of the insulating material from an extrusion plant, it is customary that initially as long as molten and made liquid extrudate is pressed through the extruder until all old paint residues are washed out of the system and the new desired color has been stable and homogeneous.
    The effluent in a container insulating material that has never come into contact with metallic conductor material can be supplied to the crushing process after its curing. From the purely polymeric starting material, the Rohkörnung, created after the crushing process a Cebrauchskörnung that has absolutely no metallic impurities. In addition, it is readily possible, by obtaining large "chunks" from the washout process due to the confluence of large amounts of extrudate, by the subsequent grinding process, if necessary, to produce larger particle sizes. Restrictions in the grain size, which arise due to the shell geometry of the old cable used, do not exist in the proposed solution.
    In addition, now results in a meaningful use for the lumps of waste from the rinsing process, which are previously added only to a thermal recovery.
    The polymeric floor covering is not thermoplastic, which is why it can not be remelted and reused and consists of a blend polymer of polyethylene and silane, wherein the proportion of silane in the blend polymer is between 0.5% and 2%, preferably about 1%.
    In order to ensure ideal properties as Reitplatztretschicht, the flooring according to the invention has a layer thickness between 30 mm and 1 50 mm, preferably between 40 mm and 1 20 mm, preferably between 50 mm and 100 mm. Thus, the tread layer is not too thick to provide sufficient strength and not too thin, to prevent the horse's hooves push through to the underlying nonwoven layer.
    The grain size in the Nutzgrinding is between 5 mm and 1 5 mm, 7 mm and 12 mm, 8 mm and 10 mm and the bed of flooring is unbound.
    Exemplary Embodiment The invention is explained below with reference to an exemplary embodiment.
    The drawing shows the typical structure of a floor covering according to the invention in cross section.
    On the soil 1, a layer of gravel and / or lava 2 is first applied followed by a nonwoven layer 3. Separated by the nonwoven layer 3 from the gravel now the flooring according to the invention follows 4 as a loose bed of polymeric granules use in a thickness of 50 mm to 100 mm.
