Abstract

Procedimientos de tratamiento de una materia fibrosa mineral con vistas a realizar su desfibrado, caracterizado porque consiste en hacer sufrir a la materia, previamente humedecida en forma de una masa plástica o seudo-plástica, pero no obstante compacta, una fluencia bajo presión, en el curso de la cual es sometida esencialmente a solicitaciones de cizallamiento, sensiblemente con exclusión de solicitaciones de percusión o de esfuerzos de flexión sobre las fibras, permaneciendo éstas libres de orientarse en la masa plástica en función de las resultantes de las solicitudes de fluencia.
