Abstract
Mejoras introducidas en el objeto de la patente principal nº 426.443, presentada el 18 de Mayo de 1.974, por: Procedimiento de fabricación de diafragmas porosos de amianto depositado y consolidados por una resina fluorada, según el cual se forma una suspensión homogénea y estable, añadiendo a una suspensión de fibras de amianto en agua, en presencia de un agente surfactante anionico sulfonico, un látex de resina fluorada y un agente poroforo, porque se pone esta suspensión en forma por filtración, porque se la seca, porque se la calcina a una temperatura superior al punto de fusión, en estado cristalino, de la resina fluorada, y porque se elimina el poroforo por descomposición, caracterizado porque se asocia a la membrana microsporosa así obtenida un elemento de refuerzo integrandolo en la cara anódica de la membrana, presentando el elemento de refuerzo una estructura al menos tan abierta, con respecto al paso del líquido en electrólisis, como la membrana porosa.
