摘要
利用液体包装纸板的实际生产工艺,探讨了不同打浆度和纤维配比对液体包装纸板面层纤维基片抗张指数、撕裂指数、耐破指数、挺度、松厚度和内结合强度的影响,并通过压痕测试研究了其在加工应用上的适应性。结果表明,在改善液体包装纸板面层纤维基片强度性能上,优化打浆工艺比增加针叶木浆配比效果更好,针叶木浆/阔叶木浆配比为1∶1,打浆度22°SR时撕裂指数最大为13.4 mN·m^(2)/g;打浆度25°SR时挺度最大为85.9 mN·m^(2)打浆度29°SR时耐破指数和抗张指数最大分别为5.82 kPa·m^(2)/g和68.2 N·m/g,此条件下压痕测试数据和效果表现佳。
The effects of different beating degree and fiber ratio on properties of surface layer fiber sheets of liquid packaging paper board were studied by the actual production technology of liquid packaging paper board,including tensile index,tear index,burst index,stiffness,bulk and bonding force.The adaptability in processing applications was also studied by crease testing.The results showed that the optimization of the beating process was better than the increase in the softwood pulp ratio in terms of the improvement in strength properties of liquid packaging paperboard surface layer fiber sheets.When the softwood wood pulp and hardwood pulp ratio was 1∶1,the tear index reached maximum of 13.4 mN·m^(2)/g with beating degree of 22°SR,the stiffness reached maximum of 85.9 mN·m with beating degree of 25°SR,the burst index and tensile index reached maximum of 5.82 kPa·m^(2)/g and 68.2 N·m/g,respectively,with beating degree of 29°SR.The crease testing results exhibited the better results under this condition.
