Question 1: What is Nuanbaobao and what is it used for? Nuanbaobao is a registered trademark of Kobayashi Pharmaceutical Co., Ltd. approved by the Trademark Office of the State Administration for Industry and Commerce. It is not a common name for winter heating tablet products.
In the industry, the formal and common name of this type of product is disposable heating pads. Various manufacturers in the industry have different names, such as heating packs, heating patches or thermal patches, etc., each In order to prevent trademark infringement, regular manufacturers avoid using similar terms such as warm baby or warm baby stickers.
Warm baby is also called warm patch. Its reaction principle is that the raw material layer in the warm patch can continuously release the amount of warm patch within 12-20 hours under the action of oxygen in the air. This reaction The process begins as soon as the vacuum packaging is opened. In order for the temperature to last longer, the product uses the mineral material vermiculite to insulate it. Because the product cannot react before use, the bag material must be very special, consisting of a raw material layer, a gelatin layer and a non-woven bag. Non-woven bags are made of microporous breathable membrane. It must also have a conventional airtight outer bag - a gelatin layer. When using, remove the outer bag and expose the inner bag (non-woven bag) to the air, and the oxygen in the air will enter through the breathable membrane. The time and temperature of heat release are controlled by the oxygen permeability rate of the breathable membrane. If the oxygen permeates too quickly, the heat will be released all at once, and the skin may be burned. If the oxygen permeation is too slow, there will be no temperature. After use, it becomes a dark brown solid, which contains carbon powder, NaCl solid, Fe2O3 solid and salts containing magnesium and aluminum.
Question 2: What is a warm baby? The first one is: rechargeable. Wear it on your body after charging. It is very warm. The price is between 20 and 30 yuan.
The second type is: like a plaster, it can be applied to underwear or soles of the feet without staining the clothes. A large pack costs about 30 yuan, with a pack of more than 10 pieces. It is very warm when applied to the body. It can last for more than 10 hours. It is a one-time use and costs 2 to 3 pieces per piece.
The third kind is: the same as the second kind, but no need to stick it, just hold it in your hand and rub it around, it will be very warm. Just like a bag of tea bags
I recommend the second one. Although it is not as affordable as the first one, it is really useful for the elderly and girls. It is clean, light, and warm
Question 3: The principle of "Nuanbaobao" is a synthetic mixture of iron, vermiculite, activated carbon, inorganic salts, water, etc. Among them, vermiculite is a kind of iron and magnesium Vermiculite is a quality aluminosilicate mineral whose composition is Mg0.5(H2O)4Mg3[AlSi3O10](OH)2. It is named after its ability to expand rapidly when heated and bend into the shape of a leech (leech). It is generally brown or brown-yellow. Or dark green, with a greased glass luster. About 80% of expanded vermiculite is used in the construction industry and is a good thermal insulation and sound insulation material. Vermiculite is the world's leading super insulation material after a series of complex processes. After chemical treatment, the extracted vermiculite film is translucent. The surface layer of this film has excellent thermal insulation properties and is used to make fireproof coverings, roof heat protection, high-temperature gaskets, expansion joints for furnaces or boilers, and refrigerators. It is suitable for the heat protection layer of household appliances, incubators and cable outer coverings.
So, what is the heating principle of the "warm baby" we use? The reaction principle of "Warm Baby" and the products after use are explored and identified.
2. Principle Analysis
"Nuanbaobao" uses the heat released by the iron oxidation reaction to generate heat. In fact, It is based on the principle that iron absorbs oxygen and corrodes in humid air. At the same time, the strong adsorption property of activated carbon is used to store water vapor in the loose structure of activated carbon. The water vapor liquefies into water droplets and flows out to contact with air and iron powder. During chlorination. Under the catalysis of sodium, the reaction occurs relatively quickly to generate iron hydroxide, releasing heat.
The oxidation reaction rate of iron under natural conditions is slow. If you can speed up this reaction, you can try to increase the iron content. By using water, salt and activated carbon to form a primary battery to promote the reaction, you can obtain the temperature required by the heating bag and become the heat source of the heating bag. It will not cause harm to the body, just don't burn yourself.
Negative electrode: Fe-2e-＝Fe2+
Positive electrode: O2 + 2H2O + 4e-＝4OH-
Total reaction: 2Fe + O2 + 2H2O＝2Fe (OH)2
2Fe(OH)2 + 2H2O + 3O2＝4Fe(OH)3↓
2Fe(OH)3 ==== Fe2O3+3H2O
Question 4: What is inside the warm baby patch? The raw material layer of the warm patch can continuously release heat within 12-20 hours under the action of oxygen in the air. This reaction process starts from the moment the vacuum package is opened. It started at that time.
The baby warmer must be applied across clothes and generally does not touch the skin. The raw material layer inside it is a polymer synthesized from iron, stone, activated carbon, inorganic salts, water, etc. It will not cause any great harm to the skin, but it is best not to touch the skin~
Question 5: What is inside the Nuanbaby thermal patch? Why do you get hot by yourself? At first glance, I saw that the owner just bought Nuanbaobao. I just found some introduction to the heating principle of the warm baby from the blog of Hengda Warm Baby. You will understand it at a glance:
The warm baby is composed of a raw material layer, a gelatin layer, and no The woven bag consists of three parts.
The raw material layer is placed inside the non-woven bag, and the gelatin layer is used to make the body warmer adhere to the clothes.
The raw material layer is a polymer synthesized from iron, stone, activated carbon, inorganic salts, water, etc.
It can undergo an exothermic reaction under the action of oxygen in the air.
At present, this product is not very standardized. The products look similar, but the quality is uneven.
Genuine baby warmers warm up quickly, heat evenly, last for a long time, have moderate viscosity, and do not fall.
For example, Hengda Company’s Beibei Bear Warmer is among similar products. It is very popular and is now the number one selling warm patch online. 20 million pieces were sold online last November. In addition to Beibei Xiong, Shangle Portable Warm and Hexin Portable Warm are also heating patch brands produced by Hengda Company! Among them, Sangle's steam-type eye protection patches were also selected as *** gifts by the United Nations Pavilion at the Shanghai World Expo!
Question 6: What brand of warm baby patches is good? Warm baby patches are suitable for people who are afraid of cold. Still a good choice. When you go out in the cold winter, wearing a warm baby patch can prevent frostbite and expel the cold. It is very effective. Moreover, the warm baby patch is easy to carry and the fever is long-lasting and stable. Just put on a thin piece of warm baby patch every day to withstand your daily stress. cold. There are quite a few brands of baby warmers: Kangaroo baby warmers, Xiaolin Kepao baby warmers, Koala baby warmers, Sankang warmers, Golden Rabbit baby warmers, Flying Eagle baby warmers, etc.
Question 7: What is the principle of warming the baby? Introduction to Nuanbaobao Nuanbaobao was first invented by the Japanese and emerged in Japan. It is the latest generation of Japanese high-tech products. The product is as thin as paper, light as cotton, soft and elastic.
With the improvement of people’s living standards, disposable heating products are also widely used in people’s lives. Due to different names, they can be divided into: thermal patches, heating patches, heating sheets, hand warmers, hand warmers, Yitie Hot, Foot Warming Patch, Menstrual Relaxation Patch, Warming Gongbao, Women's Menstrual Warming Patch, Portable Warming Patch, etc.
The reaction principle of Nuanbaobao: The reaction principle of Nuanbaobao is to use primary batteries to speed up the oxidation reaction and convert chemical energy into thermal energy. In order for the temperature to last longer, the product uses the mineral material vermiculite to insulate it.
Because the product cannot react before use, the material of the bag must be very special, consisting of a raw material layer, a gelatin layer and a non-woven bag. Non-woven bags are made of microporous breathable membrane. It must also have a regular airtight outer bag - a gelatin layer. When using, remove the outer bag and expose the inner bag (non-woven bag) to the air, and the oxygen in the air will enter inside through the breathable membrane.
The time and temperature of heat release are controlled by the oxygen permeability rate of the breathable membrane. If the oxygen permeates too quickly, the heat will be released all at once, and the skin may be burned. If the oxygen permeation is too slow, there will be no temperature.
After use, it will be a dark brown solid, which contains carbon powder, NaCl solid, Fe2O3 solid and salts containing magnesium and aluminum.
Precautions for using Warm Baby: At present, this product is not very standardized. Under many names, the products are similar, but the quality is uneven.
Inapplicable groups:
Pregnant women: If the patch is facing the uterus, it is likely to cause uterine contraction, resulting in fetal malformation and premature birth. Infants: Infants have very tender skin and little activity, which prevents low-temperature burns.
People with diabetes, blood circulation disorders, and those with low skin thermal sensitivity should pay attention when using it.
Attach it to the outside of the underwear, do not attach it directly to the human skin (except for the muscle patch type).
It should not be used when sleeping at night to prevent low-temperature burns.
Avoid damage or damage to the vacuum plastic packaging bag, otherwise the product will fail.
If it accidentally comes into contact with eyes, rinse immediately with clean water and seek medical treatment. If swallowed by mistake, induce vomiting and seek medical treatment immediately.
Nuanbaobao is originally for medical use. As long as it is genuine, there should be no side effects.
Don’t buy fake ones that cost just a few cents. I heard that industrial iron powder is used.
Low-grade and inferior products cannot be used
