What is in the ice bag?
It is a high-capacity, non-toxic, odorless polymer compound composed of water and water
What is in the ice bag? Dry ice?
Hello, I specialize in the research and development and production of ice bags. The ice in the ice bag is not condensed by water and there is no connection with dry ice. Although they are both cold storage products, there is still a big difference between the two. of. The ice bag contains a high-tech chemical product that is boiled at high temperatures and turned into a transparent and slightly viscous liquid that is clean, hygienic, odorless and non-toxic. Compared with dry ice, it still has great advantages. Because ice packs are more convenient to use and cleaner and more hygienic. Dan's products will also be taken up a notch.
What is the liquid in the ice bag?
Sodium polyacrylate
What is the ice in the ice bag? Is it dry ice?
What is in the ice bag? It's actually just ordinary water, not dry ice or the like. It's just that when we put the ice bag in the freezer, it freezes. Once the ice bag is removed from the refrigerator, it will quickly return to water.
What is the function of ice pack and how to use it?
Ice packs have a wide range of uses, here are some of them: 1. Cooling ice packs are a high-tech product that can be reused and can be used both hot and cold. 2. Used for medical cooling, antipyretic, anti-inflammatory and analgesic, cold compress to stop bleeding, physical therapy and skin care, hot and cold compress physiotherapy bag. 3. Refrigerated transportation of various biological freezing reagents, long-distance refrigerated transportation of medicines, plasma, vaccines, aquatic products, poultry, ornamental fish and foreign trade fresh food. 4. Used for injuries such as bumps, sprains, falls, etc. during the training and competition of athletes in the sports world. 5. Cold compress: physical cooling, fever reduction, anti-inflammatory and analgesic, fatigue relief, itching relief, etc., and can quickly eliminate discomfort or pain caused by fever, headache, toothache, sprain, back pain, mumps, heat stroke, etc. It is also suitable for students to study, cool down and prevent heatstroke during exams, and refresh themselves. 6. Cold storage saves energy in daily life, maintains low temperature when the supermarket freezer is powered off, preserves food, chills drinks, and travels. 7. Refrigeration and preservation: Breast milk preservation, beer and beverage preservation, food, lunch boxes and other items refrigeration preservation, long-distance refrigerated transportation. 8. Ice packs for cakes and mooncakes: There are many ice cream cakes and snowskin mooncakes on the market. The ice packs can be placed together with cakes and mooncakes to prevent the cakes and mooncakes from deteriorating due to rising temperatures. How to use the ice pack: first put the ice pack in water, knead it with your hands to expand the technological ice, and expand it to about 1 cm for the best state. After expansion, take it out, wipe off the water on the surface, and then put it in a commercial freezer. -gui/ can be frozen and used.
What is in the disposable ice bag?
What happened to the nitric acid?
This is the ice bag that comes with buying an eye mask. I don’t know what the liquid is in it. , what is the effect?
Satisfactory answer
I put the eye mask in the refrigerator, take it out when it is cold, and then cover the eyes, which can relieve eye fatigue, because the eyes like the cold but not the cold. If you have a fever, you can use the same method to cool down, but put it on your forehead.
Because the liquid in the eye mask is at a constant temperature, it can soothe the nerves of the eyes and eyeballs after wearing it. Usually our eyes are in a blood state when they are working for a long time (of course they are not congested). That’s it. Hahaha) So the liquid eye mask helps speed up blood circulation, relaxes the eyeballs, and helps reduce pressure on the eyeballs. The principle is simple, just like hematoma caused by trauma to other parts of the body, using ice can relieve pain. However, the tissues of the eyes are very fragile and cannot be applied with ice for a long time. Extreme temperatures will damage the eyes and eyeball tissues. Therefore, the constant-temperature liquid in the eye mask can not only reduce the fatigue of the eyes caused by long periods of time, but also does not cause damage to the eyes. Can damage eyeballs and eye tissues. Please adopt
What is the use of the ice pack in the thermal bag?
Thermal bags are used to maintain a certain temperature. Some things need to be stored at low temperatures, so the ice bags inside are used to better keep cold.
Used multiple times for sitting. What kind of liquid is contained in the ice pack?
The heating principle of hand warmers
Appearance: A sealed plastic bag filled with transparent liquid, with a metal piece 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, and 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 the hot summer, it can be used as a cold pack, used 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 warmer, 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/100m of constant 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 a supersaturated solution of 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 and reused. 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.
Urgent! ! ~What are the ingredients in ordinary cooling ice packs (not medical ones)? What's the principle?
Ordinary ice bags are filled with high molecular polymers and water-absorbent resins. The principle is to use cold sources such as refrigerators and freezers to allow the ice bags to reach the freezing point. Under the influence of the surrounding ambient temperature, they absorb the temperature and reduce the ambient temperature. It is a physical phenomenon, not a chemical reaction. Ice bags are used to keep food, fruits, seafood, etc. fresh and warm during transportation. They have no toxic or side effects and are food-grade raw materials.
