摘　　要：两种不同游离度(CSF)(480 mL和250 mL CSF)的速生材杨木P-RC APMP浆分别与桉木漂白硫酸盐浆(BKP)(CSF425 mL)混合,通过研究混合浆在物理性能和光学性能方面的变化,探讨了杨木P-RC APMP浆和桉木BKP浆之间的协同效应。研究结果表明,低游离度的杨木P-RCAPMP浆与桉木BKP浆混合后,能够在抗张强度、抗张能量吸收、湿抗张强度和撕裂度等方面产生协同效应;混合浆的松厚度和不透明度随杨木P-RC APMP浆配比量的增加而增加;但是混合浆的白度会受到较低白度的杨木P-RC APMP浆的影响。The fast-growing poplar P-RC APMP with two different freenesses were mixed respectively with a bleached eucalyptus kraft pulp（BKP）.The synergistic effect between the poplar P-RC APMP and eucalyptus BKP was explored by investigating the changes of the physical and optical properties of the blended pulps.The results showed that after blending the low-strength poplar P-RC APMP and eucalyptus BKP,a synergistic effects of the tensile strength,tensile energy absorption（T.E.A）,re-wet tensile strength,tear strength,and so on could be occurred.The bulk and opacity of the blended pulp increased as the blending ratio of the poplar P-RC APMP increased.About 14%~25% increase in tensile strength of the blended pulp could be obtained compared to the eucalyptus BKP alone.However,the brightness of the blended pulp was impacted by that of the poplar P-RC APMP.
