摘要:综合讨论了填料的各种性能包括粒径和比表面积、亲水亲油性能、颗粒形态、碱度,以及填料与施胶剂之间的反应对纸张施胶效果的影响,并从填料的包覆改性技术、新型填料的开发研究、各种助剂的协同使用以及施胶剂和填料加入点位置的优化等几个方面总结了目前国内外解决加填纸施胶问题的相关措施。

Abstract:In this paper, the impacts of filler properties including particle size and specific surface area, hydrophilicity and hydrophobicity, particle morphology, alkalinity of fillers, and reactions between fillers and sizing agents on sizing results of the filled paper were discussed. The progress and current research efforts targeting the sizing problems in filled paper, which include the technology of surface sizing and modification of various fillers, development of new types of filler, synergetic use of various chemical additives, and the optimization of addition points of sizing agents and fillers, were also summarized.
