| 中文摘要: |
| 通过DMSO/KOH/H2O体系对对位芳纶浆粕表面进行活化处理，复合间位芳纶沉析纤维后，共同作为三维支撑骨架，并以4A型分子筛为吸附剂，通过湿法成形，制得芳纶纤维/分子筛纸基过滤材料。结果表明，当对位芳纶浆粕、间位芳纶沉析纤维质量及比例不变，分子筛添加量为1.5 g时，芳纶纤维/分子筛纸基过滤材料综合性能最佳，断裂应力为8 MPa，透气度6 μm/（Pa·s），对PMs和甲醛的去除率分别达99.99%和93.17%。 |
| Abstract: |
| Using para-aramid pulp/meta-aramid precipitated fiber as the three-dimensional supporting skeleton， of which the para-aramid pulp surface was activated by the DMSO/KOH/H2O system， and 4A type molecular sieve as the adsorbent， the aramid fiber/molecular sieve paper-based materials were prepared via wet forming by compounding para-aramid pulp， meta-aramid precipitated fiber and molecular sieve. The results showed that when the mass ratio of para-aramid pulp， meta-aramid precipitated fiber did not be changed， and molecular sieve additive amount was 1.5 g， the prepared aramid fiber/molecular sieve paper-based material had the best comprehensive performance， with breaking stress of 8 MPa， air permeability of 35 μm/（Pa·s）， and removal rate towards PMs and formaldehyde of 99.99% and 93.17%， respectively. |
