So far many organic and inorganic materials have been used as a dehydrating agent. Among those, inorganic salts and porous materials were most widely used for various applications. Inorganic slats, like CaCl2 and MgCl2, has very good dehydrating capacity and speed even at the low relative humidity condition. But it changes to corrosive liquid after contact with moisture, so it’s application was restricted. On the other hand, some porous materials, like silica-gel and zeolite, are not changed to liquid but the dehydration capacity is not enough in many applications. So a new material with safe to use and high moisture absorption is needed to be studied, and this study is dedicated to the preparation and property measurement on the new dehydration agent based on cross-linked polyacrylate metal salts. |
