Patent

CA 2456521

A heat-resistant filter which comprises a heat-resistant organic fiber substrate and, fixed thereto, a resin composition comprising an alkaline substance. The filter is reduced in the degree of the decrease in tensile strength and folding endurance, even after it is used under a high temperature condition, and is less prone to the failure of the material thereof even when it is used at a high temperature, and thus is capable of achieving a useful life of a long period of time.

L'invention concerne un filtre résistant à la chaleur qui comprend un substrat de fibres organiques résistant à la chaleur et une composition de résine comprenant un produit alcalin fixée sur ce substrat. La diminution de la résistance en traction et de la résistance au pliage de ce filtre demeurent réduites, même après une utilisation dans des conditions de haute température. Ce filtre présente un risque réduit de défaillance du matériel, même lorsqu'il utilisé à haute température, ce qui lui assure une longue durée de vie utile.
