The reaction principle is also to use oxidation-reduction reactions to convert chemical energy into heat energy. In order to make the temperature last longer, the product uses the mineral material vermiculite for heat preservation, and more importantly, allows oxygen to enter slowly, so the material of the filling bag should be very special, consisting of raw material layer, gelatin layer, breathable film and non-woven Composed of cloth bags. The non-woven fabric should be attached with a layer of microporous breathable membrane. In addition, there must be a conventional airtight outer bag-commonly known as a plastic bag. When in use, tear open the outer bag to expose the inner bag (non-woven bag) to the air, and the oxygen in the air enters the inside through the breathable membrane. The heating time and temperature are controlled by the oxygen permeability rate of the gas-permeable membrane. If the oxygen intake is too much, the reaction will quickly release the heat, and it may burn the skin. If the oxygen permeation is too slow, the reaction will be slower and the heat will be less, and there will be no temperature. After use, it is a russet solid, which contains carbon powder, NaCl solid, Fe3O4 solid and salts.
