(FR) MECHE DE VERRANNE CONTENANT DE L'AL2O3, A HAUTE RESISTANCE THERMIQUE ET A FORT CARACTERE TEXTILE, AINSI QUE PRODUITS DERIVES
Abstract:
(DE) Die vorliegende Erfindung betrifft ein Al2O3-haltiges, hochtextiles und hochtemperaturbeständiges Glasstapelfaservorgarn auf Kieselsäurebasis mit einem baumwollartigen, voluminösen Charakter, Glasstapelfaserprodukte aus diesem Vorgarn sowie deren Verwendung. Der textile Charakter und die Hochtemperaturbeständigkeit werden insbesondere durch eine selektive Säureextraktion erlangt. Die Zusammensetzung des erfindungsgemäßen Glasstapelfaservorgarns umfaßt insbesondere SiO2 als Hauptkomponente sowie 1 bis 5 Masse-% Al2O3 als Nebenkomponente.
(EN) The invention relates to Al2O3-containing, high temperature resistant glass sliver based on silicic acid, having a highly textile, cotton-like and voluminous character. The invention also relates to glass staple fiber products from said glass sliver and their use. The textile character and high temperature resistance are obtained in particular by selective acid extraction. The composition of the inventive glass sliver comprises in particular SiO2, as main component, and 1-5 weight% Al2O3, as subsidiary components.
(FR) L'invention concerne une mèche de verranne contenant de l'Al2O3 à haute résistance thermique et à fort caractère textile, à base d'acide silicique et présentant un caractère volumineux semblable à du coton, ainsi que des produits en verranne fabriqués avec cette mèche et leur utilisation. On obtient le caractère textile et la haute résistance thermique en particulier par une extraction d'acide sélective. La composition de la mèche de verranne selon l'invention comprend en particulier du SiO2 comme constituant principal ainsi que 1 à 5 % en poids d'Al2O3 comme constituant secondaire.
