摘要:本研究以11种桉木和5种相思木为研究对象,使用多种统计学模型拟合分析了16种原料的材性特征(β-β结构单元含量、原浆白度)与其在2种预浸渍溶出物处理工艺(全洗净与全保留)下可漂性的关系。结果表明,所有原料β-β结构单元含量与可漂性呈显著负相关关系,而原浆白度与可漂性呈正相关关系;预浸渍溶出物全洗净工艺的模型拟合效果显著优于全保留工艺,其中桉木在全洗净工艺下的二次变换模型决定系数(R^(2))高达0.90,表明β-β结构单元含量和原浆白度对可漂性的影响显著;全保留工艺的模型拟合效果较差(R^(2)<0.66),表明预浸渍溶出物的保留削弱了材性参数对可漂性的解释能力,其对原料可漂性的影响不容忽视;同时发现,桉木与相思木的材性特征具有协同建模潜力,相思木数据的引入未对模型拟合效果产生显著影响。
This study investigated 11 eucalyptus and 5 acacia wood species,employing multiple statistical models(including multivariate linear regression,exponential models,and quadratic transformation models)to analyze the correlations between material characteristics(β-βstructural unit content,original pulp brightness)and bleachability under two pre-impregnation dissolved substance treatment processes(fullwash and full-retention).The results demonstrated thatβ-βstructural unit content exhibited a significant negative correlation with bleachability,while original pulp brightness showed a positive correlation in all raw materials.The full-wash process achieved superior model fitting performance compared to the full-retention process.Specifically,the quadratic transformation model for eucalyptus under the full-wash process yielded a determination coefficient(R^(2))of 0.90,indicating thatβ-βstructural unit content and original pulp brightness significantly influenced bleachability.In contrast,the full-retention process showed poorer model performance(R^(2)<0.66),suggesting that retained pre-impregnation dissolved substances weakened the explanatory power of material characteristics on bleachability.Additionally,eucalyptus and acacia exhibited synergistic modeling potential,as the inclusion of acacia data did not significantly compromise model accuracy.
