In this paper, the exothermal efficiency and exothermal rate were employed to evaluate and optimize the composition of the self-heating material, and the effects of each component were discussed. The final optimized composition as below: reduced iron powder (20%), potassium permanganate (60%), sodium chloride (10%), activated carbon (10%). Under the optimized conditions, the temperature of this self-heating material could up to 100 °C within 2 min and maintain for 20 min, which should be suitable for flameless fast food self-heating or providing heat source for physiotherapy equipment in the medical field. |
