Abstract

The work aims to develop a new type of dehumidification adsorbent by compounding commonly used adsorbents. Metal halide was combined with polymer or high specific surface area material to prepare composite adsorbents. The saturated moisture absorption of ACF/CaCl₂ adsorbent, MCM-41/CaCl₂ adsorbent, MWNT/CaCl₂ adsorbent, PVA/CaCl₂ adsorbent, super absorbent resin and nano mildew-proof and moisture-proof adsorbent was 1.8, 1.6, 1.5, 1.4, 0.8 and 0.5, respectively, and the humidity of the above adsorbents per unit mass was 70% in a closed environment with accumulated water and an initial humidity of 99.9% and the time for maintaining such a humidity was 76, 51, 38, 33 and 0 h, respectively. ACF/CaCl₂ adsorbent and MCM-41/CaCl₂ adsorbent have the best comprehensive performance and possess certain application potential in dehumidification of storage cabin environment on missile boats.
