The performance targets before and after the application of Duoshake,such as the paper formation,tensile strength,extensibility,MD/CD strength difference and two-sidedness are compared and the influence of Duoshake on sheet properties is discussed.
本文比较分析了Duoshake使用前后纸张匀度、抗张强度、伸长率、纵横差、两面差等性能指标,探讨了Duoshake对纸张性能的影响,得到以下结论：(1)Duoshake的使用可以有效改善纸张的匀度,尤其是对定量在170g/m~2以上的纸张,改善幅度可达到10%～20%；(2)可以减小纸张的纵横差,提高纸张的物理强度；(3)增大了纸张的两面差,尤其是低定量的纸张,两面差增幅达到7%～15%。
The formation of the PBO paper was greatly increased and the strength properties were also improved after oxygen plasma treatment.
实验结果表明,氧等离子体处理是PBO浆粕十分有效的改性手段;经过氧等离子体处理后,PBO浆粕增加了活性基团,从而改善了浆粕的分散性能,提高纸页匀度;同时,PBO纸页的强度也有大幅度提高,裂断长从3。
