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 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 becomes a dark brown solid, which contains carbon powder, NaCl solid, Fe2O3 solid and salts containing magnesium and aluminum.

Question 2: 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 is from a It starts when the vacuum packaging is opened.

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 3: What are the ingredients in Warm Baby? There are some scratches on the packaging bag of Nuanbaobao. If you buy genuine products from the supermarket, there will be a label with Chinese instructions on the back: the main ingredients include: iron powder, water, salt, wood powder, activated carbon, etc.

< p> Continuously generates heat through the exothermic characteristics of the iron oxidation process

There is no so-called phosphor component, maybe you are not familiar with the product you are using

< p> Therefore, there are many fake and shoddy things on the market now. It is best to choose regular stores to buy.

It is best to have a customs clearance certificate or agency certificate. If the price is very cheap, the non-woven fabric inside is contaminated.

After use, it is as hard as a brick, so congratulations, you have bought a fake.

Or if you buy a small amount, the store will not deliver the goods, for fear of inspection, because such sellers are A one-shot deal!

If you want to distinguish between true and false, go to Taobao store ID: golden1997. There will be detailed explanation and analysis, and you will definitely gain something.

Warning: It doesn’t matter if you spend a few cents more, the key is not to cause any harm to your body. , no one is responsible if something goes wrong!

Question 4: What is the black thing inside the warm baby? Because the main ingredients inside the warm baby are iron powder, activated carbon, hydrated compounds, salt, etc. When the package is opened, iron will be produced when the warm patch comes into contact with the air. The chemical principle of powder oxidation causes heat not only when it is attached to the body, but because it heats up when it comes into contact with the air. When it heats up, it will expand a little

Question 5: Warm the baby What kind of material are the particles inside made of? Are they cold or warm? It mainly includes: iron powder, water, salt (edible salt), vermiculite, activated carbon 1. The iron powder reacts with oxygen and moisture that pass through the breathable membrane, and is reduced to iron oxide, releasing hydrogen and releasing heat; 2. The function of edible salt is to corrode iron powder and accelerate the oxidation rate of iron powder (many colleagues who do not know the truth should refer to this ingredient by the so-called catalyst); 3. Vermiculite is a fluffy porous structure, which mainly acts as a catalyst. The role of the carrier is that the iron powder has enough space to fully react with oxygen and plays a certain role in insulation. (Some small manufacturers will use wood powder to replace vermiculite. Wood powder is used in many places in the country. It is free. Although the two have the same effect, the structure of vermiculite determines that it plays a better role than wood powder. To a certain extent, it will help to improve the heating time and reaction degree of the product) 4. Activated carbon Its main function is to absorb excess water produced during the reaction and ensure the reaction environment. For your reference

Question 6: What kind of substance is in the Warm Baby Patch! What a principle! 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 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 7: What picture is inside Nuanbaobao? Iron sand.

Question 8: What is the liquid in Warm Baby? It is a supersaturated solution with unknown ingredients. When the metal piece is pulled, friction is actually applied to eliminate the unstable "stable" state of the supersaturated solution, causing the solution to form tiny crystal nuclei on the surface of the metal piece and grow rapidly, consuming the supersaturated part of the solute in the solution. Until the solution reaches a stable saturated state, this process is exothermic. This is the principle of Rebao.

Heating can make it absorb heat again and return to its original state, which is equivalent to storing heat energy.

Because the concentration of the supersaturated solution is too high, it is not stable. When you twist a metal, the slight vibrations produced are enough to crystallize the solute into a more stable solid. However, this process is exothermic, so the hand warmer begins to warm up.

At a certain temperature, the solubility of a solute in a solvent remains unchanged. For example, the solubility of salt (sodium chloride) in water is 36g/100mL of water at room temperature. . When the concentration of a solution is equal to its solubility, the solution is called a saturated solution; when the solubility of the solution is higher than its solubility, the solution is called a supersaturated solution. The liquid in the hand warmer bag is supersaturated solution sodium acetate (sodium?acetate,?CH3COONa).

The heating principle of hand warmer

Appearance: a sealed plastic bag, It is filled with a clear liquid and a metal piece is placed in the liquid.

In order to be more comprehensive, I have also posted the "Instructions for Use":

1. Use - gently bend the metal piece in the bag, the liquid in the bag will appear crystalline (blue color translucent), hardens into a solid. The heating temperature is about 50 degrees (about 1 hour).

2. Reserve - After use, boil it in boiling water for 10 minutes until the crystals completely return to a transparent liquid. After cooling, it can be used again.

3. The product can be used repeatedly according to the above method.

4. In hot summer, you can use it as a cold pack, like an ice pack, to prevent and cool down, but it needs to be frozen in the refrigerator before use.

To understand the principle of "Hand Warmer" hand warming, we first need to know what a supersaturated solution is. At a certain temperature, the solubility of a solute in a solvent remains unchanged. For example, the solubility of salt (sodium chloride) in water is 36g/100mL of water at room temperature. When the concentration of a solution is equal to its solubility, the solution is called a saturated solution; when the solubility of the solution is higher than its solubility, the solution is called a supersaturated solution. The liquid in the hand warmer bag is supersaturated solution sodium acetate (sodium?acetate,?CH3COONa).

Because the concentration of the supersaturated solution is too high, it is not stable. When you twist a metal, the slight vibrations produced are enough to crystallize the solute into a more stable solid. However, this process is exothermic, so the hand warmer begins to warm up.

One advantage of hand warmers is that they can be recycled. As long as you put the hand warmer bag into boiling water and heat it for about 10 minutes, the condensed solute will dissolve again; this is because the solubility of the solute increases at high temperatures. During the dissolution process, the solute undergoes an endothermic reaction and becomes a supersaturated solution again.

It is said that the packaging seems to be made of PVB material. This material is non-toxic at room temperature, but it will release toxic substances when heated. This kind of product has not been tested by the State Administration of Quality Supervision, and its safety needs to be considered.
