Abstract

L~invention concerne un procédé de production d~une pâte chimico-mécanique à partir d~un matériau de base qui comprend des copeaux de bois. Selon le procédé, dans un premier temps, le matériau de base en bois est traité à la vapeur à une température élevée pour éliminer l~air des copeaux de bois. Ensuite, lors du stade d~imprégnation, les copeaux de bois traités à la vapeur sont mis en contact avec une solution d~imprégnation alcaline dans des conditions dans lesquelles l~alcali pénètre dans les copeaux de bois. Par la suite, afin de produire la pâte, les copeaux de bois traités avec l~alcali sont raffinés jusqu~à l~obtention d~une aptitude à l~égouttage souhaitée. Conformément à la présente invention, le stade d~imprégnation s~effectue à une surpression, ce qui permet de réduire la dose d~alcali lors de l~imprégnation et ainsi d~accroître la diffusion de la pâte sans accroître le pourcentage de bûchettes. Au même indice d~égouttage, le bouffant est également amélioré.
