Abstract:

在密闭空间实际工况下,通过两组平行对照试验,考察了长时间吸脱附循环对固态胺材料CO2吸附性能的影响,对材料进行长寿命试验,并验证一年内固态胺材料性能的稳定性。结果表明,两组试验分别经过2128轮和2267轮吸脱附循环后,固态胺材料仍表现出良好的吸脱附稳定性。在长寿命试验条件下,两组吸附剂的CO2的吸附量维持在约28mg·g-1,有机胺含量未见流失,活性胺含量比初始材料有所提高并不再降低,材料机械强度未受到影响。结果证明,高分子树脂基固态胺材料不仅能在室温条件下高效吸附CO2,且能在温和条件下实现CO2的解吸,在减少能耗的同时还有利于材料使用寿命的延长,适宜作为太空密闭空间中去除低浓度CO2的吸附材料,为航天员的生命保障提供技术支撑。
