The little sun that walks in winter -- warm the baby
How does it heat up
You know what
Thermal materials for warmed babies consist mainly of iron powder, activated carbon, neptunium, water, salt, etc. Thermal principles are used to heat thermally using the iron oxide reaction。
In fact, the conversion of chemical energy to thermal energy is based on the principle of oxygen corrosion of iron in humid air. Using the strong adsorption of activated carbon, aqueous vapour is stored in the accelerator structure of activated carbon, water vapour is liquidized into water droplets, ejected in contact with air and iron powder, and reacts more rapidly to produce iron hydroxide and release heat under the catalytic effect of sodium chloride。
Iron powder: react with oxygen, release heat
Oxygen in air reacts with iron powder to produce iron oxide, which releases heat when it is corroded. These heats bring iron powder to about 68°c。
Activated carbon: adsorption of moisture to ensure a smooth oxidation process
The role of activated carbon is to absorb the water in the air and ensure that the process of oxidation is carried out smoothly. It also has thermal function, so it spreads the heat evenly. The volume of charcoal swells after heating。
Sodium chloride: catalyst, catalytic iron powder corrosion
Sodium chloride (salt) as an ice-free agent in snowy cities corrosives vulnerable parts of cars. Here, sodium chloride (with water) is a catalyst for iron powder corrosion。
Lysol: temperature insulation to avoid burns
This hydro-rich magnesium silicate will swell when heated and look like worms. It is light and has good water-absorption properties, does not react chemically in warm babies and does not smell alien. It is therefore a super-material with fire protection functions. Ribbon is insulation and is sometimes used as construction material. It spreads the iron powder evenly with activated carbon, avoiding overheating and burning the skin。
Where's the warmest sticker
1. Cervical vertebrates: a warm baby is attached to the cervical vertebrae and warms the whole body。
2. A person who fears the cold may be placed behind his waist: if he fears the cold on a day-to-day basis and has no special symptoms, he or she may be placed behind his or her waist。
3. On the back of the outer garment: the warmer baby is most warm on the back of the outer coat, which allows the whole body to feel the heat or choose according to its needs。
4. Menstruation may be placed on the abdomen: in the case of menstruation, the option is to be placed on the lower abdomen of the outer abdomen。
5. Artificial arthritis patients are given joints: cold on their knees and cold on their bodies, so that it warms them。
6. Shoulder neck disease warms the shoulder neck: in the case of a shoulder neck disease or a person who is winded on the shoulder in winter by wearing a low-collar coat, it can be applied to the shoulder or back neck to accelerate the circulation of blood in the neck and to mitigate symptoms of discomfort。
7. Indigents: if winter is cold and indigestion, they can be attached to the stomach, which makes them feel warm and promotes nutritional digestion and absorption. Note not to be attached directly to the skin。
The warm baby is using the guide
When the baby is torn apart, the substance inside is exposed to air oxidation and then heat. Watch out, rip it open and put it in a few minutes。
The “hot baby” should not be attached to the same place for long periods of time, either because the skin is inhaled in a hot state or to prevent the skin from burning。
If a “hot baby” has been placed on its body, no more equipment such as heaters should be used to prevent local temperatures from burning the skin。
The choice is for a branded “hot baby” to see the brand, date of production, etc。
Attention
1. Warm babies may not be used in combination with heating devices such as electric heat blankets, and when sleeping, do not use warm patches to avoid burns。
2. Warm babies cannot be attached directly to their skin, otherwise they will cause burns and avoid the use of warm babies at the same location for long periods of time, which should cease immediately if the skin is found to be ill。
3. Special groups of ill-health should be used with caution to prevent burns at low temperatures. Children, older persons and those unable to take care of themselves should be used under special care。
4. Warm must not be attached to clothing, such as sweaters, which are easily torn. Warm babies can only be used for external use, and when used do not rip open their inner bags in order to prevent the leaking of heat materials in their inner bags and to avoid entering their eyes or mouths. If the eyes are not reached, the water is washed and treated immediately, and when the food is lost, the vomiting and medical attention is given immediately。
People who don't use warm babies
1. Pregnant women and pre-pregnant women: the placing of a warm baby in the abdomen can cause excessive internal heat in the pregnant woman and the intra-breath, and the fetus can be followed by a variety of thermal diseases, such as defecation, scabies, etc., after birth; it can be attached to the correct position of the uterus, which can cause severe contraction of the uterus, affect the position of the foetus and even lead to deformation and premature birth。
2. Children, especially infants: due to their tender skin, they are unable to express their discomfort accurately and are prone to burns。
Diabetes, blood circulation disorders, heat-sensitive and old and infirm: it doesn't apply because the nerve ends feel retarded。
4. In winter, when there are no cold conditions, it is advisable not to use: warm babies are mainly suitable for cold, i. E. Cold people with cold hands and feet in winter, who often catch cold; for people who are not cold, warm babies produce excessive heat over a long period of time, causing overheating and discomfort。
