METHOD FOR MANUFACTURING HIGH-QUALITY HOT PACK HAVING EXTENDED EXOTHERMIC PERIOD AND ENHANCED EXOTHERMIC STRENGTH AND APPARATUS FOR MANUFACTURING HIGH-QUALITY HOT PACK COMPRISING MEANS FOR PREVENTING AIR EXPOSURE OF THERMOGENIC MATERIALS

摘要

The present invention provides technical contents related to a method for manufacturing hot pack with improved quality such as exothermic period, exothermic strength, and the like by minimizing the air exposure of a thermogenic mixture filling the hot pack during a process of transferring for manufacturing the hot pack; and to an apparatus for conducting the method. The thermogenic mixture is obtained by mixing iron powder, activated carbon, a hygroscopic resin, salt, a water retaining agent and water in a nitrogen gas atmosphere.;COPYRIGHT KIPO 2018
