摘要
聚对苯二甲酰对苯二胺(PPTA)浆粕对PPTA纸的成形起着重要的作用,但是浆粕形态复杂难以表征。本文通过比表面积、扫描电镜(SEM)和长径比等测试方法研究了PPTA浆粕的形态结构,用打浆度和动态滤水性的测定来表征PPTA浆粕的滤水性能,并分析了各浆粕的抄纸性能。
PPTA pulp is important to forming of PPTA paper, but it is hard to characterize because of its complex morphology. PPTA pulp's morphology was studied by specific area, SEM and length-diameter ratio. Drainability was characterized by degree of beating and dynamic drainage. The paper properties of PPTA pulp were analyzed.
