摘要 研究使用杨木高得率浆(HYP)和桦木HYP部分取代全化学浆优质纸张生产过程中使用的硫酸盐阔叶木浆对纸张松厚度和平滑度的影响。结果表明,杨木HYP和桦木HYP可显著提高纸张松厚度、挺度及不透明度。由于桦木纤维粗大其影响也较大,但是随着桦木HYP使用比例的增加,纸张平滑度有下降趋势,而且纸张强度也有所下降。HYP浆种的选择和取代比例应根据所生产的纸张品种和等级而定。 Two typical HYPs used in wood-flee paper grades, aspen HYP and birch HYP, were investigated for their effects on the bulk and surface roughness when substituting for hardwood kraft pulp in wood-free fine paper production. Results show that paper bulk, bending stiffness, and opacity can be improved significantly by both aspen and birch HYPs. Birch HYP has greater effects since birch fibres are larger and have higher coarseness. However, increasing HYP substitution rate increases paper surface roughness and decreases paper strength. Selection of HYP species and substitution rate should be made based on the needs of a specific paper grade.
