Abstract

<B><MU>CORREIA POROSA OU PANO DE FILTRAGEM<MV><D> Uma correia porosa ou pano de filtragem compreende um substrato têxtil, tecido ou não-tecido (11), o qual é revestido em pelo menos uma superfície, com uma camada de polímero coagulado (12). A camada (12) de preferência impregna substancialmente o substrato, e o substrato têxtil, se não-tecido, poderá ser suportado em uma membrana de malha (23), ou um tecido enlaçado em espiral (32). Alternativamente, uma camada de partículas sintéticas (42) poderão ser incorporadas sobre o substrato que é coberto pela camada de polímero coagulado e impregnado pela mesma.<B> <MU> POROUS BELT OR FILTER CLOTH <MV> <D> A porous belt or filter cloth comprises a textile, woven or non-woven substrate (11), which is coated on at least one surface, with a layer of coagulated polymer (12). The layer (12) preferably substantially impregnates the substrate, and the textile substrate, if non-woven, may be supported on a mesh membrane (23), or a spiral-bound fabric (32). Alternatively, a layer of synthetic particles (42) may be incorporated on the substrate which is covered by the layer of coagulated polymer and impregnated by it.
