| description | An insulating mat (20) for an exhaust gas treatment device (10) thermally stable to at least 900°C, wherein the insulating mat contains inorganic fibers uniformly coated with a metal oxide including at least one of aluminum oxide, titanium oxide, zirconium oxide, or mixtures thereof; wherein said fibers are uniformly coated with the metal oxide by precipitating metal hydroxide corresponding to the metal oxide on the fibers, followed by converting the precipitated metal hydroxide to the metal oxide. A method of increasing the thermal stability of inorganic fibers for use in an exhaust gas treatment device insulating mat including the inorganic fibers, including uniformly coating the fibers with a metal oxide of at least one of aluminum oxide, titanium oxide, zirconium oxide or mixtures thereof by a chemical precipitation process.
L'invention concerne un tapis isolant (20) pour un dispositif de traitement des gaz d'échappement (10) thermiquement stable jusqu'à au moins 900°C, le tapis isolant contenant des fibres inorganiques enduites de manière uniforme par un oxyde métallique comprenant au moins l'un parmi l'oxyde d'aluminium, l'oxyde de titane, l'oxyde de zirconium, ou des mélanges de ceux-ci ; lesdites fibres étant enduites de manière uniforme par l'oxyde métallique par précipitation de l'hydroxyde métallique correspondant à l'oxyde métallique sur les fibres, suivie de la conversion de l'hydroxyde métallique précipité en oxyde métallique. L'invention concerne un procédé permettant d'augmenter la stabilité thermique de fibres inorganiques à des fins d'utilisation dans un tapis isolant d'un dispositif de traitement des gaz d'échappement comprenant les fibres inorganiques, comprenant l'enduction uniforme des fibres avec un oxyde métallique d'au moins l'un parmi l'oxyde d'aluminium, l'oxyde de titane, l'oxyde de zirconium ou des mélanges de ceux-ci par un procédé de précipitation chimique. |
