采用沙柳为原料生产高得率碱性H2O2化学机械浆,发现在NaOH总用量为8%,H2O2总用量为10%时,和沙柳单段P-RC APMP浆料相比,沙柳双段P-RC APMP浆料的白度增加8.34%,裂断长增加21.82%,耐破指数增加24.83%;浆料内的细小纤维较沙柳单段P-RC APMP中的细小纤维多,纤维表面的碎片较多,纤维分丝帚化的程度较大;纤维的结晶度降低了3.45%。
Using Salix as raw material to produce high-yielding alkaline H2O2 chemomechanical pulp, it was found that when the total amount of NaOH was 8% and the total amount of H2O2 was 10%, compared with Salix psammophila P-RC APMP slurry, The whiteness of P-RC APMP pulp increased by 8.34%, the breaking length increased by 21.82% and the burst index increased by 24.83%. The fine fibers in the pulp were more than the fine fibers in Salix psammophila P-RC APMP. The fiber surface More fragments, fiber broom broom a greater degree; fiber crystallinity decreased by 3.45%.
