Abstract Wood processing residue, as an essential forest resource, is underestimated in the industrial applications. With the development of pulping technology, fiber quality and cost control have become the important prospects. It is very crucial to investigate the influencing factors of pulping, designed to reveal the relationship between fiber separation and physical performances. In this study, a range of effect factors of large-scale pulping process, including wood species, pretreatment, mechanical conditions, and post-bleaching treatment, were comprehensively investigated. The results illustrated that the industrial pulping process affected the dimensions of the fibers, their surface morphology, chemical structure, and thermal stability. The separated positions of the fibers were determined collectively by the mechanical temperature, time, and wood species. In addition, mild bleaching could effectively increase the crystallinity index, accessibility of the hydroxyl groups, and water retention values. However, it exerted a negative influence on the thermal stability. Further, chemical-assisted-refinement can replace higher temperature and prolonged ones to obtain pulp fibers with high quality while consuming less energy. Improved knowledge of how the industrial affects the fiber separation of a wood matrix and pulp quality is required as a basis for the development of the pulp and paper industry.

工业加工对木材残留物纸浆纤维性能影响的综合评价

摘要 木材加工残渣作为一种重要的森林资源，在工业应用中被低估了。随着制浆技术的发展，纤维质量和成本控制已成为重要的前景。研究制浆的影响因素非常重要，旨在揭示纤维分离与物理性能之间的关系。在这项研究中，对大规模制浆过程的一系列影响因素进行了综合研究，包括木材种类、预处理、机械条件和漂白后处理。结果表明，工业制浆过程影响了纤维的尺寸、表面形态、化学结构和热稳定性。纤维的分离位置由机械温度、时间、和木种。此外，轻度漂白可以有效提高结晶度指数、羟基的可及性和保水值。然而，它对热稳定性产生负面影响。此外，化学辅助精制可以代替高温和长时间的精制，获得高质量的纸浆纤维，同时消耗更少的能源。需要进一步了解工业如何影响木材基质的纤维分离和纸浆质量，作为纸浆和造纸工业发展的基础。化学辅助精制可以代替高温和长时间的精制，获得高质量的纸浆纤维，同时消耗更少的能源。需要进一步了解工业如何影响木材基质的纤维分离和纸浆质量，作为纸浆和造纸工业发展的基础。化学辅助精制可以代替高温和长时间的精制，获得高质量的纸浆纤维，同时消耗更少的能源。需要进一步了解工业如何影响木材基质的纤维分离和纸浆质量，作为纸浆和造纸工业发展的基础。
