Large RH fluctuations lead to dimensional changes, deformation for organic materials.
Silica gels [4], minerals [5] and charcoals [6], inorganic salt [7] and polymer gel [8] are widely used as the basic materials of humidity control material.
Thus, composite humidity control materials are favored and developed widely [9, 10].

Then artifitical zeolites can be synthetized by chemical reagent or other materials, such as red mud, fly ash, kaolin, tailings and so on.
As the cost of zeolites synthetized by chemical reagent is relatively high, waste residue as raw material is worth research.
Materials and Methods The fly ash used in this study was obtained from Hexi power plants located in Inner Mongolia, China.
