摘要

采用Bauer McNett纤维分级机,以原始混合硬木化学纸浆为原料,以纤维和细纤维两种输出物料筛选初级细纤维。将筛选的细纤维掺入纸浆中,得到无细纤维、细纤维含量为10%和20%的纸浆。所有纸浆样品的精炼都在PFI磨机中进行。与没有细粒的牙髓相比,细粒含量为10%和20%的牙髓分别需要10.8和28.9%的PFI转数来获得400ml CSF水平。在相同的自由度水平下,添加10%和20%的罚款,纸张的不透明度分别增加1.7和2.6点。同样,在纸浆中分别添加10%和20%的细粉,纸张的形成率也提高了2.0和10.2%。纸张的体积和刚度随着添加到450毫升CSF水平的罚款而改善。随着细粉的加入,材料的断裂长度、破裂指数、撕裂指数、双折、斯科特键等强度性能均有所降低。

Use of Primary Fiber Fines as Organic Fillers in Papermaking
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.

期刊介绍: The Taiwan Journal of Forest Science is an academic publication that welcomes contributions from around the world. The journal covers all aspects of forest research, both basic and applied, including Forest Biology and Ecology (tree breeding, silviculture, soils, etc.), Forest Management (watershed management, forest pests and diseases, forest fire, wildlife, recreation, etc.), Biotechnology, and Wood Science. Manuscripts acceptable to the journal include (1) research papers, (2) research notes, (3) review articles, and (4) monographs. A research note differs from a research paper in its scope which is less-comprehensive, yet it contains important information. In other words, a research note offers an innovative perspective or new discovery which is worthy of early disclosure.
