The principle of foot warmer
The reaction principle is also to use redox reaction to convert chemical energy into heat energy. In order to make the temperature last longer, the product uses the mineral material vermiculite to keep warm, and more importantly, the slow entry of oxygen, so the material of the filling bag should be very special, composed of raw material layer, gelatin layer, breathable film and non-woven Composition 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 and expose the inner bag (non-woven bag) to the air, and the oxygen in the air enters the inside through the breathable membrane. The time and temperature of heating are controlled by the oxygen transmission rate of the breathable 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 slow, and the heat will be less, and there will be no temperature. After use, it is a reddish brown solid, which contains carbon powder, NaCl solid, Fe3O4 solid and salts.
