Abstract

PROCEDIMIENTO PARA LA PREPARACION DE PASTA MECANICA DE MADERA EN UN DESFIBRADOR. LA MADERA SE COMPRIME EN UNA CUBA CONTRA LA MUELA DEL DESFIBRADOR, AL TIEMPO QUE SE SUMINISTRA, A LA ZONA DE AMOLADO, UN LIQUIDO CON UNA TEMPERATURA DE EBULLICION, A PRESION ATMOSFERICA, SUPERIOR A 115GC. EL LIQUIDO USADO PUEDE SER AGUA MEZCLADA CON SAL, ALCOHOL, MEZCLA DE GLICERINA Y AGUA O AGUA A LA QUE SE HAN AÑADIDO AGENTES ELEVADORES DEL PUNTO DE EBULLICION.
