Abstract

Un feutre en fibre minérale (5) contenant un liant organique, est mis en oeuvre pour l'isolation d'une surface chaude (3) d'un appareil thermique (1), la température de la surface chaude (3) étant d'un niveau tel que le liant se décomposerait et produirait une gêne due aux odeurs. Pour éviter cela, on réduit à zéro la teneur en liant dans une zone superficielle (6) voisine de la surface chaude (3), ce pour quoi un traitement thermique de la surface (7) correspondante du feutre en fibre minérale (5), pendant la fabrication, est spécialement indiquée ceci conduisant à une décomposition correspondante du liant. La surface (7), débarrasée de liant, peut être traitée ensuite à une température au-dessus de la température de ramollissement des fibres minérales, de façon à obtenir une consolidation mécanique.A mineral fiber felt (5) containing an organic binder is used for the insulation of a hot surface (3) of a thermal device (1), the temperature of the hot surface (3) being a level such that the binder would decompose and produce discomfort from odors. To avoid this, the content of binder is reduced to zero in a surface area (6) close to the hot surface (3), which is why a heat treatment of the corresponding surface (7) of the mineral fiber felt (5), during manufacture, this is specially indicated, leading to a corresponding decomposition of the binder. The surface (7), freed of binder, can then be treated at a temperature above the softening temperature of the mineral fibers, so as to obtain mechanical consolidation.
