disposable self-heating body warmer
The body warmer is composed of a raw material layer, a gelatin layer and a non-woven bag. The function of the gelatin layer is to prevent the product from reacting before use. The non-woven bag is made of microporous breathable film. When the outer bag is removed, the inner bag (non-woven bag) is exposed to the air. The oxygen enters the inside through the gas-permeable membrane. The time and temperature of the heat release are controlled by the oxygen permeability rate of the gas-permeable membrane. If the oxygen permeation is too fast, the heat will be released at once and the skin may be burned. If the oxygen permeation is too slow, there will be no temperature. The raw material layer is the layer where the reactants are located. The warm baby heating material is mainly composed of iron powder, activated carbon, vermiculite, water, salt and other materials. The reaction principle is to use the galvanic battery to accelerate the oxidation reaction speed and convert chemical energ
