Abstract

un método para producir una pulpa quimiomecánica a partir de madera como materia prima que comprende astillas de madera. De acuerdo con el método, primero la materia prima compuesta por madera se vaporiza a una temperatura elevada para remover el aire de las astillas de madera, luego, en la etapa de impregnacion las astillas de madera vaporizadas entran en contacto con una solucion de impregnacion alcalina bajo condiciones en las cuales el álcali penetra en las astillas de madera y, después de ello, para producir la pulpa, las astillas de madera que se tratan con el álcali se refinan hasta lograr una drenabilidad deseada. De acuerdo con la presente, la etapa de impregnacion se lleva a cabo a una sobrepresion, en cuyo caso es posible disminuir la dosis de álcali de la impregnacion y, de este modo, aumentar la difusion de la pulpa, sin aumentar el porcentaje de esquirlas. En el mismo grado de drenaje de la pulpa, también mejora la masa.
