Abstract

EN UN PROCESO PARA LA FABRICACION DE PULPAS DE MADERA QUIMIOMECANICAS Y/O QUIMIOTERMOMECANICAS, LAS MATERIAS PRIMAS QUE CONTIENEN LIGNOCELULOSA, COMO POR EJEMPLO VIRUTAS DE MADERA, ASTILLAS DE MADERA, MADERA PREMOLIDA O SERRIN, SE IMPREGNAN PRIMERO CON UNA SOLUCION DE SO SUB 2 ALCOHOLICA ACUOSA Y SE CALIENTAN DESPUES A UNA TEMPERATURA ENTRE 50 Y 170 C DURANTE 1 A 300 MINUTOS. LAS VIRUTAS DE MADERA SE MUELEN ENTONCES AL GRADO DE FINEZA DESEADO EN UN DISPOSITIVO DESFIBRINADOR QUE ES CONOCIDO PER SE. EL PROCESO HACE QUE SEA POSIBLE ALCANZAR HASTA UNA REDUCCION DEL 50% DE LA ENERGIA DE MOLIENDA EN COMPARACION A LOS PROCESOS QUIMIOTERMOMECANICOS CONOCIDOS.
