Abstract

UN FILTRO DE FIBRA (10) DE MATERIAL FIBROSO PERMEABLE A LOS FLUIDOS TIENE UN CUERPO COMPUESTO (12) PLANO CON UNA CAPA SUPERIOR Y UNA CAPA INFERIOR (14 O 18), ENTRE LAS CUALES ESTAN ALOJADAS PARTICULAS (16) SUELTAS DE UN AGENTE DE RELLENO DE GRANO FINO, POR EJEMPLO, CARBONO ACTIVO, FIJADAS MEDIANTE PUNTOS ADHESIVOS (20). LA CAPA DE PARTICULAS ES ESENCIALMENTE MAS GRUESA QUE LAS CAPAS SUPERIOR E INFERIOR (14;18) DE LAS CUALES AL MENOS UNA PUEDE ESTAR IMPREGNADA. SE CONSIGUE UNA PERMEABILIDAD AL AIRE DE AL MENOS 1.200 L/M{SUP,2}, OSCILANDO EL TAMAÑO DE LAS PARTICULAS (16) ENTRE 0,1 Y 6 MM (ENTRE 0,3 Y 1,0 MM), QUE PUEDEN ESTAR CONSTITUIDAS DE MATERIAL INORGANICO Y/O ORGANICO, ADEMAS DE INTERCAMBIADORES IONICOS, CATALIZADORES, SUPERABSORBENTES O SIMILARES. EL ADHESIVO TERMOFUNDIBLE (S) SE ABLANDA PREFERENTEMENTE ENTRE 100 Y 145 (GRADOS) C. EL CONTENIDO DE PARTICULAS ESTA, POR EJEMPLO, ENTRE EL 8 % Y EL 15 % DEL PESO DEL ADHESIVO TERMOFUNDIBLE. EL CUERPO COMPUESTO (12) CALANDRADO COMO ARTICULO RODANTE O ARTICULO PLANO PUEDE TENER UN GROSOR ENTRE 0,4 Y 8 MM (1,5 A 3,0 MM). PARA LA FABRICACION SE ROCIA LA CAPA INFERIOR DE MATERIAL FIBROSO (14) CON UN ADHESIVO TERMOFUNDIBLE (S) Y PROVISTO DE PARTICULAS DE RELLENO (16), SOBRE EL QUE SE COLOCA LA CAPA SUPERIOR (18). EL ADHESIVO TERMOFUNDIBLE PUEDE PULVERIZARSE O EXTENDERSE HACIA ABAJO O BIEN OBLICUAMENTE A LA CAPA INFERIOR (14). SIMULTANEAMENTE O POSTERIORMENTE LAS PARTICULAS (16) SON REPARTIDAS, EVENTUALMENTE OBLICUAMENTE O TRANSVERSALMENTE A LA DIRECCION DE PULVERIZACION O DE GOTEO DEL ADHESIVO TERMOFUNDIBLE (S) Y/O EN DIRECCION CONTRARIA A LA DEL SENTIDO (L) DE UNA CINTA DE SOPORTE (T).
