比较了加入纳米纤维素(NFC)的漂白桉木浆与抄造书写印刷纸和胶版印刷纸的传统漂白桉木浆的物理性能。为此,制备了3种浆料:打浆浆料、加入NFC的未打浆浆料、轻度打浆且加入NFC的浆料。结果表明,加入NFC的未打浆浆料的物理性能与抄造书写印刷纸浆料的物理性能基本相同;预先轻度打浆而后加入NFC的浆料的性能最好。这一结果显示,加入NFC可以降低打浆强度而不会降低浆料的强度性能。
The physical properties of bleached eucalyptus pulp incorporating nano-cellulose (NFC) and conventional bleached eucalyptus pulp for writing and offset printing paper and offset printing paper were compared. For this purpose, three slurries were prepared: beating slurry, adding NFC non-beating slurry, light beating and adding NFC slurry. The results show that the physical properties of non-beaten pulp with NFC are basically the same as that of carbon-based printed paper; the pulp with pre-mild beating and then NFC is the best. This result shows that adding NFC can reduce the beating strength without decreasing the strength properties of the slurry.
