吉林四种野生杨柳科植物纤维特性及制浆造纸性能分析
Analysis of Fiber Characteristics and Pulping and Papermaking Properties of Four Wild Salicaceae in Jilin Province
摘要
Abstract
In order to alleviate the shortage of papermaking raw materials in pulp and paper production,four wild Salicaceae species from Jilin province,namely Salix matsudana,Salix raddeana,Populus davidiana,and Populus cathayana were used as pulp and papermaking raw materials in this article.The surface morphology of fibers was observed using optical microscopy and scanning electron microscopy.The fiber characteristics,including length,width,aspect ratio,coarseness,density and crystallinity,as well as the chemical composition were analyzed for four wild plant raw materials.The research results indicated that the biological structures of the four plant materials had significant differences.Among them,S.matsudana was short fiber,while S.raddeana,P.davidiana,and P.cathayana possessed intermediate length fibers.The aspect ratios of the four wild plants were all greater than 36,with fiber densities ranging from 1.22 to 1.57 g/cm3 and fiber crystallinity between 76.88%and 79.36%,and the fiber surface was richly intertwined,making them suitable for papermaking.Analysis of the three major components of cellulose,hemicellulose,and lignin in four wild plant fiber materials revealed that the cellulose content of all four materials was approximately 40%,which could meet the daily papermaking needs.After kraft pulping and screening,the fine pulp yield of four wild plants was over 40%.After pulping and papermaking,the physical properties of the paper showed good performance,suggesting that these fibers could serve as partial substitutes to alleviate the shortage of papermaking raw materials.Among them,the physical performance indicators of S.matsudana paper were the best,with a tensile index of 42.56 N·m/g,a burst index of 4.68 kPa·m2/g,and a tear index of 6.52 mN·m2/g.关键词
