Abstract
This paper presents an experimental investigation of the thermal characteristics in a layer of an exothermic powder mixture that is utilized in body warmers, hot compresses, etc. The research objective is to develop a manufacturing method that enables the exothermic temperature to be controlled in order to prevent cases of low-temperature burns. This powder mixture is composed of iron powder, activated carbon powder, vermiculite and NaCl. The variation over time of the temperature distribution and the generated heat in a layer of the exothermic powder mixture is measured. Absorbent polymer and nonwoven fabric are used to control the water and oxygen volume supplied into the layer, and their effects are examined.
