摘　　要：通过与变色硅胶和蒙脱石进行比较,研究了魔芋超强吸水剂(KSAP)在不同湿度环境下的吸湿性能,同时对它们进行了解吸性能比较,了解它们在吸湿后的保水性能。结果表明,在RH=30%±1%,T=25±1℃时,硅胶和蒙脱石的吸湿性较好;在RH=75%±1%,T=25±1℃和RH=90%±1%,T=25±1℃的环境中,硅胶和蒙脱石在1d前较KSAP高,但之后KSAP的吸湿性表现较好,9d时吸湿率分别达到70%和120%,且保水能力好。The moisture absorption and desorption of Konjac superabsorbent polymer （KSAP）, silica gel and mentor-rock desiccant in different humidity were studied. The result indicated that the moisture absorption of silica gel and mentor-rock was better than KSAP at RH=30%±1%, T=25±1℃. At RH=75%±1%, T=25±1℃ and RH=90%±1%, T= 25＋1℃, silica gel and mentor-rock was superior to KSAP in 1d, then KSAP was the best, the absorptivity of which reached 70% and 120% for 9d respectively. KSAP also had good water retention.
