Abstract

Procedimiento para la fabricación de abrasivos, que contienen al menos dos capas de aglutinante, con empleo de al menos un resol I) acuoso, preparado a partir de un fenol monovalente, con una proporción molar de fenol a formaldehído desde 1:1,1 hasta 1:2,5, con o sin otros aditivos habituales, aplicándose una primera capa de aglutinante sobre un material de soporte flexible de forma plana, y secándose esta capa de recubrimiento, después de haber esparcido el grano abrasivo, con empleo de una instalación de secado horizontal, hasta la consistencia y resistencia posterior al encolado, y después enfriándose mediante una corriente de aire, después de lo cual se aplica una segunda capa de aglutinante, a base del mismo o de otro aglutinante.
