中文摘要 | 初生纖細物以一具Bauer-McNett纖維篩分機從混合樹種原生化學漿中篩選出,並與纖維部份分離。篩出的纖細物混入紙漿中以分別獲得不含纖細物以及含10與20%纖細物之紙漿,其分別較不含纖細物紙漿減少10.8與28.9%之PFI打漿紙轉數而達到400 ml CSF游離度之程度。於相同之游離度下,添加10與20%纖細物所抄紙張之不透明度分別增加1.7與2.6百分點。同時添加10與20%纖細物紙漿所抄之紙,交織分別改善了2.0與10.2%。紙之嵩度與剛挺度亦隨纖細物的添加而改善,至紙漿游離度450 ml CSF之程度。強度性質,如抗張斷裂長、破裂指數、撕裂指數、耐折度與Scott層間結合強度等則隨纖細物添加而減低。 |
英文摘要 | Primary fiber fines were screened out of virgin mixed hardwood chemical pulp through a Bauer McNett Fiber Classifier with 2 output materials of fibers and fines. The screened primary fiber fines were blended into the pulp to obtain pulps with no fines, and with 10 and 20% fines. The refining of all pulp samples was carried out in a PFI mill. The pulp with 10 and 20% fines respectively required 10.8 and 28.9% fewer PFI revolutions to obtain a 400 ml CSF level compared to the pulp without fines. At the same freeness level, the opacity of the paper increased with the addition of 10 and 20% fines by 1.7 and 2.6 points, respectively. Similarly, the formation of paper also improved by 2.0, and 10.2% with the respective addition of 10 and 20% fines to the pulp. The bulk and stiffness of the paper improved with the addition of fines up to a 450 ml CSF level. The strength properties, such as the breaking length, burst index, tear index, double fold, and Scott bond, decreased with the addition of fines. |
