Abstract
Procedimiento para fabricar un diafragma de amianto de una cuba de electrolisis con diafragma, según el cual se forma un fieltro que comprende fibras de amianto, se tratan las fibras de amianto con una solución que contiene iones de metal alcalino, se seca y se hace compacto el fieltro haciendo que la atraviese un flujo de aire, y luego se calienta, caracterizado porque se utiliza un flujo de aire caliente para secar y hacer compacto el fieltro.
