摘要：探讨了分别加填TiO_2和CaCO_3对漂白高得率浆成纸强度性能和光学性能的影响。加填后,成纸抗张强度、耐破度和层间结合强度均有不同程度的降低。与CaCO_3加填纸相比,TiO_2加填纸的强度性能降低幅度较小。加填TiO_2可显著提高纸张的白度、不透明度和光散射系数。加填纸光散射系数相同时,TiO_2用量仅为CaCO_3用量的1/4。加填TiO_2可显著抑制高得率浆光诱导返黄,并且随其留着量的增加,抑制效果增强;TiO_2留着量为21.4%,加填纸光诱导返黄程度降低76.4%。加填CaCO_3对漂白高得率浆的光诱导返黄的抑制作用较小。
The effects of TiO2 and CaCO3 as fillers on the strength and optical properties of bleached high yield pulp （HYP） were investigated.It was shown that the tensile strength,bursting strength and bonding strength of the handsheets from HYP decreased in different degrees with the increment of the fillers.Comparing with the CaCO3,the sheet strength decreased smaller when TiO2 was used as filler.And the brightness,opacity and especially the light scattering coefficient of the TiO2-filled sheets were improved obviously.The same light scattering coefficient was obtained when the dosage of TiO2 was only one fourth of that of CaCO3.Furthermore,an obvious inhibition of brightness reversion of HYP was achieved by TiO2 filling,and the inhibition effect on brightness reversion increased with the increment of TiO2.The HYP brightness reversion was reduced by 76.4% when the TiO2 retention amount was 21.4%.Comparatively,the inhibition effect on the brightness reversion was weak for CaCO3 filling.
