在芳纶浆粕的3种主要制备方法基础上,分析了Dupont与Teijin两家公司的商品浆粕的技术指标,然后分别对芳纶浆粕的7种指标——表面形貌、比表面积、长度及其分布、抓附力、滤水性能、保水值和比浓对数黏度进行了分析讨论。最后指出:芳纶浆粕最重要的技术指标是比表面积和纤维长度及其分布,以及由两者综合决定的浆粕有效比表面积。
Based on the three main preparation methods of aramid pulp, the technical indexes of commercial pulps of Dupont and Teijin were analyzed. Then seven indexes of aramid pulp, such as surface morphology, specific surface area, Length and distribution, grasping force, drainage performance, water retention and inherent viscosity were discussed. Finally, it is pointed out that the most important technical index of aramid pulp is the specific surface area, the fiber length and its distribution, and the effective specific surface area of the pulp which is determined by the combination of the two.
