Title
(DE) VERWENDUNG EINES BEFESTIGUNGSELEMENTS AUS KUNSTSTOFF
(EN) USE OF A FASTENING ELEMENT MADE OF PLASTIC
(FR) UTILISATION D'UN ELEMENT DE FIXATION EN MATIERE PLASTIQUE
Abstract
(DE)
Verwendung eines Befestigungselements, insbesondere einer Schraube (17), einer Mutter, eines Gewindeeinsatzes (12), eines Niets, einer Gewindebuchse (16) oder eines Gewindestifts aus Kunststoff zusammen mit einem Bauteil aus einem mit dem Kunststoff und dem Befestigungselement bei einer gemeinsamen Wiederverwertung kompatiblen Werkstoff, insbesondere Kunststoff. Das Einschraubgewinde (4, 8, 15) des Befestigungselements kann selbstfurchend sein und das Material des Befestigungselements gegenüber dem Material des Bauteils eine höhere Festigkeit, z.B. durch Glasfasern besitzen. Miteinander kompatible Kunststoffe, auch wenn sie mit Füllstoffen versehen sind, lassen sich ohne vorheriges Aussortieren bei allen herkömmlichen Verarbeitungsverfahren wiederverwerten.
(EN)
A fastening element, in particular a screw (17), a nut, a threaded insert (12), a rivet, an insert nut (16) or a threaded pin made of plastic is used together with a component made of a material, in particular a plastic material, compatible with the plastic and the fastening element as regards their common recycling. The screw thread (4, 8, 15) of the fastening element may be self-cutting and the material of the fastening element may have a higher resistance than the material of the component, for example by the use of glass fibres. Compatible plastics, even when they are provided with fillers, can be recycled together by all usual treatment processes without prior sorting.
(FR)
On utilise un élément de fixation, notamment une vis (17), un écrou, une broche filetée (12), un rivet, une douille taraudée (16) ou une tige filetée en plastique, associé à un élément en un matériau compatible avec le plastique et avec l'élément de fixation en vue de leur recyclage commun, notamment une matière plastique. Le filetage (4, 8, 15) de l'élément de fixation peut être auto-taraudeur et le matériau dont est constitué l'élément de fixation peut avoir une résistance supérieure à celle du matériau dont est constituée l'élément associé, par exemple par adjonction de fibres de verre. On peut recycler ensemble des matières plastiques compatibles par tous les procédés connus de traitement, même lorsqu'elles sont pourvues de charges, sans avoir à les trier au préalable.
