过氧化氢在造纸法薄片中的应用初探

Preliminary Application of Hydrogen Peroxide in Paper-making Reconstituted Tobacco

为提升造纸法薄片纸基的感官品质，在碱性条件下用质量分数为3％的过氧化氢溶液处理造纸法薄片浆料，通过正交试验设计，实验室抄片评吸，结果表明：用绝干浆料2％添加量的过氧化氢溶液处理浆料45min，可以有效提升片基的感官品质；在此条件下片基中木质素质量分数降低了0．5％，下降比例达9．4％，片基的10min吸水高度增加0．4cm，抗张强度降低了16．3kN／m^2，其他物理指标没有明显差异。

In order to improve the sensory quality of paper-base of paper-making reconstituted tobacco, the pulp of paper-base were treated by 3% hydrogen peroxide solution under alkaline condition using orthogonal experimental design and sensory evaluation. The sensory quality of paper-base could be improved obviously under the treating conditions that 2% hydrogen peroxide solution were added to the pulp（dry basis） and treating time was 45 min. The content of lignin in the paper-base decreased 0.5%, decreased by 9.4% and tensile strength of paper-base decreased 16.3 kN/m^2. The height of paper-base increased 0.4 cm after absorbing water 10 min. There was no significant difference in other physical indicators.
