Abstract

PROCEDIMIENTO PARA PREPARAR UN MATERIAL COMPUESTO FIBROSO QUE COMPRENDE FIBRAS RECUBIERTAS CON UN MATERIAL INORGANICO. SE APLICA UNA SUSPENSION DE LAMINILLAS DE UN MATERIAL EN CAPAS, TAL COMO VERMICULITA, A FIBRAS COMBUSTIBLES, A UNA TEMPERATURA QUE PUEDE SER CUALQUIERA HASTA LA DE EBULLICION DEL LIQUIDO PORTADOR. EL CONTENIDO DE SOLIDOS DE LA SUSPENSION NO DEBE SER SUPERIOR A UN 40 POR 100 EN PESO. SE CONFORMAN LAS FIBRAS Y LAMINILLAS EN UN BLOQUE TRIDIMENSIONAL, DE MANERA QUE LAS FIBRAS SE REVISTAN CON LAS LAMINILLAS Y SON ALGO AGLOMERADAS ENTRE SI POR LAS LAMINILLAS EN SUS PUNTOS DE CONTACTO.
