Can a warm-up sticker stick to the soles of your feet?

Best answer: No. The slow air circulation speed of 空 on the soles of feet will affect the heating speed of the warm-up stickers, and the warm-up stickers will be very hot after reaction, so it is easy to cause burns on the soles of feet due to excessive squeezing when walking. Therefore, warm-up stickers should not be attached to soles of feet.

You can’t. The slow air circulation speed of 空 on the soles of feet will affect the heating speed of the warm-up stickers, and the warm-up stickers will be very hot after reaction, so it is easy to cause burns on the soles of feet due to excessive squeezing when walking. Therefore, warm-up stickers should not be attached to soles of feet.

Warm-up stickers are a tool for heating. The reaction principle is to use the primary battery to accelerate the oxidation reaction and convert chemical energy into heat energy. In order to keep the temperature longer, vermiculite is used to keep the temperature. Because it can’t react before use, the bag material should be very special, which is composed of raw material layer, gelatin layer and non-woven bag. The non-woven bag is made of microporous breathable film, and it must have a conventional airtight outer bag. When in use, the outer bag is removed, and the inner bag (non-woven bag) is exposed to 空 gas, and the oxygen in 空 gas enters through the breathable film. The exothermic time and temperature are controlled by the oxygen permeation rate of the breathable film. If oxygen permeates too quickly, the heat will be released at once, and the skin may be scalded. If oxygen permeation is too slow, there will be no temperature. After use, it is a dark brown solid, which contains carbon powder, sodium chloride solid, Fe2O3 solid and salts containing magnesium and aluminum.
