摘要
定量评估四川眉山地区6种丛生竹种纤维原料化学组分的造纸应用潜力,提出其原料化学组分利用潜能排序。选取慈竹(Neosinocalamus affinis)、绵竹(Bambusa intermedia)、撑绿竹(Bambusa pervariabilis)、粉单竹(Bambusa chungii)、甜龙竹(Dendrocalamus hamiltonii)和梁山慈竹(Dendrocalamus farinosus)6种当地主要丛生竹种,对其竹秆含水率、1%NaOH抽提物、苯醇抽提物、综纤维素、木质素、戊聚糖及灰分等化学组分进行分析,并运用Matlab对化学组分指标进行主成分分析,评估各竹种化学组分的造纸应用潜力综合得分值,进行排序。结果表明:6种丛生竹造纸纤维原料化学组分的主成分分析中前4个主成分方差贡献率分别为43.7%、23.8%、13.8%和12.0%,其中综纤维素、木质素和1%NaOH提取物是第一主成分的主要载荷贡献因子,戊聚糖和含水率是第二主成分中的关键载荷因子。绵竹为6种丛生竹种综纤维素含量最高的竹种,慈竹、梁山慈竹和甜龙竹三者综纤维素含量差异不显著,较绵竹和粉单竹含量低;慈竹的木质素含量显著高于其他竹种,其次为甜龙竹和梁山慈竹,粉单竹的木质素含量最低。四川眉山地区6种主要丛生竹造纸原料化学组分应用潜力排序为慈竹>撑绿竹>绵竹>粉单竹>梁山慈竹>甜龙竹。
We quantitatively evaluated and ranked the papermaking application potential of the chemical components of fiber raw materials of six sympodial bamboo species in Meishan,Sichuan,including Neosinocalamus affinis,Bambusa intermedia,Bambusa pervariabilis,Bambusa chungii,Dendrocalamus hamiltonii and Dendrocalamus farinosus.Chemical components for papermaking raw materials,including moisture content,1%sodium hydroxide solution,benzene-alcohol extraction,holocellulose,lignin,pentosan and ash content were analyzed.Matlab was used to perform principal component analysis to evaluate the papermaking application potential of the chemical components for the comprehensive scores and ranking.Among the principal components of the chemical components as papermaking fiber raw materials of the six species,the variance contribution rates of the first four principal components were 43.7%,23.8%,13.8%and 12.0%,respectively.Among them,holocellulose,lignin and 1%sodium hydroxide solution were the main loading contribution factors of the first principal component,while pentosan and moisture content were the critical loading factors of the second principal component.Among the six sympodial bamboo species,B.intermedia had the highest holocellulose content.There was no significant difference in the holocellulose content among N.affinis,D.farinosus and D.hamiltonii,which had lower holocellulose content than B.intermedia and B.chungii.N.affinis had highest lignin content,followed by D.hamiltonii and D.farinosus,and B.chungii the lowest.The application potential of the chemical components of the six main sympodial bamboos was ranked as N.affinis>B.pervariabilis>B.intermedia>B.chungii>D.farinosus>D.hamiltonii.
