| 摘 要： | 将三种不同纸浆的DCS加入浮选过程中的废新闻纸浆料,研究了DCS对废新闻纸脱墨浆浮选以及后续过氧化氢漂白效率的影响。结果表明：几种浆料中的DCS均能够改善脱墨浆的浮选效率,降低脱墨浆的残余油墨,提高脱墨浆的白度。浮选中加入杨木BCTMP和针叶木BCTMP的DCS能改善脱墨浆的可漂性,而浮选中漂白脱墨浆的DCS的存在对脱墨浆漂白的影响不大。

| Abstract: | DCS from three kinds of different pulp were added in the flotation of ONP pulp, and the influences of DCS on the flotation efficiency and the following hydrogen peroxide bleaching of deinked pulp were studied. The results show that all DCS from different kinds of pulp can improve the flo-tation efficiency, reduce residual ink and raise the brightness of DIP. The DCS from aspen BCTMP and softwood BCTMP can improve the bleachability of the deinked pulp, whereas the DCS from BDIP does not improve the bleachabi... |
