What is the principle of warm baby sticking? Precautions for using warm baby

In winter, for girls who are afraid of the cold, have they accumulated a large number of warm treasure stickers? The effect of warm stickers is the same as the hot compress principle of traditional Chinese medicine, which can be used in any part of the body. It is suitable for cold and warm in winter. It has the effects of relaxing the tendons and promoting blood circulation, dispelling wind and dispersing cold, eliminating swelling and relieving pain. What is the principle of warm baby fever?

How does a warm baby get hot?

The heating raw material of warm baby is a polymer composed of iron powder, activated carbon, vermiculite, inorganic salt and water. It can tear open the rubber layer and react with oxygen in the air immediately to generate exothermic reaction.

Iron powder

Oxygen in the air reacts with iron powder to produce iron oxide. When iron is corroded, heat will be released. These heat can make the temperature of iron powder reach about 68 ℃; the temperature of military grade heater can reach 90 ℃. In general, factories grind iron or spray molten iron with water to get iron powder. Interestingly, we eat two million pounds of iron powder every year just for breakfast.

Small porous bag

Open the plastic packaging bag, the air will penetrate into the warm baby's small bag, and the bag will start a chemical reaction that can heat up. More holes means more air, so more holes are needed to warm your baby (after all, the air in the shoes is not so flowing).

Activated carbon

The function of activated carbon is to absorb the moisture in the air and ensure the smooth oxidation process. It also has heat conduction function, so it can evenly dissipate heat. The heated charcoal expands in volume, leaving millions of holes between the carbon atoms, thus increasing the surface area per gram of carbon to 2000 square kilometers. The surface area of a pound of activated carbon is the size of six football fields -- the gaps are enough to absorb water.

sodium chloride

Sodium chloride (salt), as a deicing agent in snowy cities, will corrode the vulnerable parts of cars. Here, sodium chloride (along with water) is a catalyst that causes iron powder to corrode.

Vermiculite

This aqueous magnesium aluminum silicate expands when heated and looks like a worm. So its name comes from the Latin worm called vermiculus. It is light, strong in water absorption, does not have chemical reaction in warm baby, it does not smell, so it is a super material that can prevent fire. It's an insulator, and it's also used in some building materials. Together with activated carbon, it disperses the iron powder to prevent the filler in the warm baby from burning the skin too quickly. This is what Reptilians use to keep their eggs comfortable - and you can replace them with your own hands.

What should you pay attention to when warming your baby?

Now that you know how to warm your baby, what you need to know is how to use it correctly. Warm baby is hot as soon as it is pasted, and it has immediate effect. It's just a small sun that you carry with you. Although it has become a necessary article for many women to keep warm and keep cold, it still has potential safety hazards. Here, we remind you that you should pay attention to safety while keeping warm.

Can you warm your baby?

First, although the heat source temperature of warm baby is low, it may cause low temperature scald in the local part of human body for a long time. Therefore, special attention should be paid to: 1. Do not use warm baby while using heating appliances such as electric blanket; 2. Do not directly stick warm baby on the skin, and it is best to stick it on the outside of close fitting clothes and trousers; 3. Do not use it when sleeping, to avoid excessive pressure of turning over; 4. Avoid long time 5. Avoid placing the baby in the same place for a long time; 6. Observe the local skin condition at any time, and take it off immediately if there is any abnormality.
