混合办公废纸脱墨浆与阔叶木化学浆和BCTMP的比较

The comparison between deinked pulp of mixed office waste paper and hard wood chemical pulps and BCTMP

介绍了美国混合办公废纸脱墨浆板与美国阔叶木化学浆板、加拿大阔叶木 化学浆板和BCTMP浆板以及巴西按木浆板在成纸物理性能和光学性能方面 的比较。结果认为混合办公废纸脱墨商品浆在打浆能耗、成纸撕裂指数和 伸长率方面要优于其他浆板,在成纸不透明度和白度方面均接近阔叶木化 学浆而高于阔叶木BCTMP,成纸松厚度则仅次于BCTMP,但成纸抗张指数和 耐破指数低于阔叶木化学浆而高于BCTMP。脱墨浆成纸挺度则最低。但总的 来说,混合办公废纸脱墨浆可代替阔叶木浆用于抄造高级文化用纸。

The comparison is made between deinked pulp of mixed office waste paper from the USA and hardwood chemical pulps from the USA, hardwood chemical pulps and BCTMP from Canada and eucalyptus pulps from Brazil in physical properties and optical properties. The results show that the deinked pulp of mixed office waste paper is better than the other pulps in beating energy consumption, finished tear index and stretch, similar to hardwood chemical pulp in finished paper opacity and whiteness, lower than BCTMP in bulk density but higher than hardwood chemical pulp and lower than BCTMP in tensile index and burst index. The stiffness of deinked pulp is the lowest among all the pulps. In one word, it may be used to take the place of hard wood pulps to produce higher cultural paper.
