Abstract

Paper paste manufacturing procedure for a mechanical refining process with preimpregnation. To the conventional stages of discortezado, troceado, refining and whitening are added a fractionado to obtain particles of 1 to 5 cm. Diameter and 20 to 50 mm. Of length and chemical pretreatment or impregnation through an oxidizing alkaline attack based on sodium polysulphide at 15 per 100 in weight on wood at 130ºc and for 24 hours, which replands the middle laminate of the fibers and produces a depolimerizing action of the lignocellulose aggregates.
