In winter, many girls are afraid of the cold and will use warm baby stickers. Sometimes they will also use warm baby stickers when they have menstrual dysmenorrhea. What are warm baby stickers made of? Why do some people paste warm baby paste will bubble? Let's get to know each other.
What is the warm baby paste made of
It's mainly activated carbon, which will get hot when encountering water. There will be changes after a long time. Generally, it is used more in winter. Because of the cold winter, many people need to warm their baby because of the cold body, but they feel very comfortable when they use it, but they need to pay attention when they use it.
1. Warm baby must be pasted across the clothes, generally not touching the skin. The raw material layer in it is a polymer synthesized by iron, stone, activated carbon, inorganic salt, water, etc., which does not cause any great damage to the skin, but it is better not to touch the skin.
2. The warm pasted raw material layer can continuously release heat under the action of oxygen in the air for 12-20 hours. This reaction process starts from the time when the vacuum packaging is opened.
3. After use, it is dark brown solid, including carbon powder, NaCl solid, Fe2O3 solid and magnesium aluminum salt.
4. It can relieve the pain of waist, shoulder, stomach, leg and joint, so it is especially suitable for the elderly.
5. It has a good effect to prevent frostbite and expel cold when you go out in cold winter. It's easy to carry and has a long-lasting and stable heat. As long as you stick a thin piece every day, you can resist the cold of your day. Warm paster is the most convenient and safe heating appliance, which has become the fashionable product of international heating, cold dispelling and hot treatment.
6. Among them, iron powder reacts with oxygen and water passing through the permeable membrane, and is reduced to iron oxide, which releases hydrogen and heat.
7. The function of edible salt is to corrode iron powder and speed up the oxidation of iron powder.
What's the reason for the blister of warm baby
That's scalding, just like cupping sometimes. Skin scalded naturally has a lot of discomfort, such as blisters, which are still very hot when touched, but at this time, we should immediately stop using warm baby, because warm baby will directly damage the skin.
1. Warm baby's fever is attributed to the internal oxidation and exothermic reaction. Under the action of catalyst, the high-purity iron powder in warm baby reacts with oxygen in the air to release heat.
2. The scald caused by warm baby is low temperature scald, also known as low temperature burn or low heat burn, which refers to the gradual damage of the body from the superficial layer of dermis to the deep layer of dermis and subcutaneous tissues caused by long-term contact with the heat source of temperature & lt; 50 ℃.
3. The heat source at 49 ℃ can damage the epidermis for 3 minutes, and the epidermis will necrosis after 9 minutes.
4. In the early stage of scald, blisters were found on the skin. Because blisters will not be regarded as serious trauma, plus people's understanding of low temperature scald is not deep, and the size of warm baby is not large, the trauma area is not large, and its severity is often ignored.
5. This is a low temperature burn. It is the skin that is exposed to low temperature objects higher than body temperature for a long time that will also cause scald. If the temperature of 70 ℃ is kept for one minute, the skin may be scalded.
6. When the skin contact temperature of nearly 60 ℃ lasts for more than five minutes, it may also cause scald, which is called 'low temperature scald'. Injured skin tissue.
Taboo of using warm baby
1. If the warm baby is stored for a long time, the possibility of hole breaking will increase. Before use, it is necessary to check whether there is hole breaking, so as to prevent the heating material inside the warm baby from exposing and causing danger.
2. Children under 12 years old are not strong in self-care ability, and they are easy to ignore the temperature generated by warm baby when playing. They are more likely to suffer from burns due to long time, or children can tear them up to play as toys.
3. After falling asleep, it is very dangerous to not realize the temperature change of the warm baby in time, or to fall off or break the warm baby during sleeping.
4. Don't stick 'warm baby' on the same part for a long time. On the one hand, the skin is airtight in warm state, on the other hand, it can prevent skin scald.
5. 'three no products' cannot be used. To choose a brand of "warm baby", but also do not because the packaging indicates the brand, production date and other elements, it must be authentic.
6. Can't be used while sleeping. When sleeping, the quilt can keep warm, so that the heat generated by the warm baby can not be emitted, causing damage to the human body. In addition, the human body's perception ability decreases during sleep, and it is more likely to be scalded.
