Do you know how the recognized god of heating, the little sun walking in winter - warm baby, gets hot?
Heating principle of warming baby
The heating materials in warm baby are iron powder, activated carbon, vermiculite, inorganic salt andwaterWhen the gelatin layer is torn off, the synthetic polymer can react with oxygen in the air immediately to produce exothermic reaction.
Iron powder: oxygen in the air reacts with iron powder to produce iron oxide. When iron is corroded, it will release heat. These heat can make the temperature of iron powder reach about 68 ℃.
Porous small bag: open the plastic packaging bag, the air will seep into the warm baby small bag, and the chemical reaction that can generate heat will begin in the bag. The more holes mean the more air, so there are more holes to warm babies with feet than normal.
Activated carbon: The function of activated carbon is to absorb water in the air and ensure the smooth oxidation process. It also has the function of heat conduction, so it can dissipate heat evenly. The heated charcoal expands in volume.
Sodium chloride: As a deicing agent in snowy cities, sodium chloride (salt) will corrode the vulnerable parts of cars. Here, sodium chloride (together with water) is a catalyst that can promote the corrosion of iron powder.
Vermiculite: This hydrated magnesium aluminum silicate will expand when heated, and it looks like a worm. It is very light, has strong water absorption ability, does not have chemical reaction in warm baby, and its smell is not smelly, so it is a kind of fireproof super material. It is an insulator, which is also used in some building materials. It disperses iron powder together with activated carbon to prevent the filling in the warm baby from burning too quicklyskin。
Where is the warmest place for warm baby
1. Cervical vertebra, warm the baby's body by sticking it on the cervical vertebra.
2. People who are afraid of cold can stick it on their back waist. If they are only people who are afraid of cold on weekdays and have no special symptoms, they can stick it on the coat at the waist.
3. At the back of the coat, the warm baby sticks to the back of the coat to keep warm, which can make the whole body feel the heat. You can also choose according to your own needs.
4. You can stick it close to the abdomen during the menstrual period. If you are in the menstrual period, you can choose to stick it under the belly button of your coat. Warm babies should not touch the skin. This is especially important.
5. Arthritis patients can stick to the joint, and arthritis patients can stick to both knee joints; If your knees get cold, your body will feel cold. So sticking it on the joint can make people feel warm. Be careful not to apply it directly to the skin.
6. Shoulder and neck disease should be applied to the shoulder and neck for warmth. If there is shoulder and neck disease or the shoulder is winded in winter due to wearing low collar clothes, it can be applied to the shoulder or back neck to accelerate the blood circulation at the shoulder and neck, and alleviate the discomfort symptoms.
7. People with indigestion can apply it to their stomach. If they suffer from indigestion due to cold in winter, they can apply it to their stomach. In this way, people will feel warm and promote the digestion and absorption of nutrients. Be careful not to stick it directly on the skin.
Pay attention to safety when using warm baby
First of all, because "Warm Baby" can be purchased online, people had better choose products with brands when shopping.
Secondly, because the maximum temperature of the "warm baby" can reach 60 degrees Celsius, it is necessary to lay the "warm baby" on the outside of the underwear to prevent scalding.
Again, "Warm Baby" should not be used with other heating tools to avoid burning the skin due to excessive local temperature, nor should it be used during sleep when people's perception is weak.
Finally, pregnant womenbaby, diabetes and blood circulation disorders should not be used.
