摘　　要：被动式吸放湿是一种节能环保的调节相对湿度的手段。本文在封闭的小型环境箱内对新型复合硅胶调湿材料进行了除湿和放湿特性试验研究,结果表明该材料具有较好的调湿性能。而后,对该材料的等温吸湿性能进行了试验研究,发现其吸湿特性属于第III类型的多分子层典型吸附情况,从而进一步从材料微孔结构方面分析了该材料的调湿机理。Passive humidity control is regarded as a more environmental friendly humidity control method than traditional ones.In this paper,the absorption and desorption properties of a new type composite silica gel were experimentally studied in an environmental cabinet.The results indicated that this material had good performance for controlling the indoor air humidity.And then,the experiment of absorption properties under isothermal conditions was carried out.It was concluded that the isothermal adsorption performance of composite silica gel could be considered as the third many-molecule type,therefore its humidity control mechanism was analyzed based on the microstructure principle.
