Abstract

Procedimiento para la obtención de una membrana microporosa destinada a instalaciones de filtración, caracterizado porque se dispersan en un aglomerante, constituido por un material plástico o un preproducto formador de material plástico, partículas insolubles en él divididas finamente, de preferencia con un tamaño granular entre 7 mm y 50 mm, en una relación aproximada a la de 1 parte de aglomerante por 1 parte del material en partículas y, seguidamente, se suscita la formación estructural en membrana mientras el producto se encuentra en estado fluente, orientando las partículas perpendicularmente a la superficie de la citada membrana por paso a través de una membrana de soporte de poros groseros o bien por medios magnéticos o electrostáticos en función a la clase de partículas utilizada y, finalmente, se endurece la membrana por secado y se excluyen las partículas por disolución o ataque de corrosión con agentes químicos.
