Study on the Leak-Proof Hydrogel-Based Desiccants |
| 초록 |
Maritime transport of various products has been increased with developing seaborne trade. Moisture-sensitive products are exposed to a large amount of moisture during transport and broken down. Ionic salts having deliquescence often used as a desiccant. Although ionic salts produce water by moisture absorption, the leak of ionic salt-based aqueous solution seriously disrupts the products, In this study, hydrogel-based desiccants were prepared by calcium chloride(CaCl2) or magnesium chloride(MgCl2) exhibiting deliquescence with carboxymethyl cellulose(CMC) having different degree of substitution. Moisture absorption ratio of the hydrogel-based desiccants depended on the kind and the content of the deliquescent ionic salts and the substitution degree of CMC. However, viscosity of the hydrogel-based desiccants inversely decreased with increasing moisture absorption ratio. It is considered that physical crosslinking of hydrogel-based desiccants affects on the these properties. |
