What's in the ice pack? It is not hot this summer.

In the hot summer, what people want is to be able to cool themselves down and have a weapon of their own. Now it's not a luxury. Have an ice pack, which can be either iced or hot. It is also very convenient and effective to use. But what's in the ice pack? What substance has such a magical effect? Today, let Bian Xiao tell you what's in the ice pack.

What's in the ice pack?

Chemical ice pack: This product is a portable chemical ice pack, which uses the negative heat of solution of component A (sodium sulfate decahydrate) and component B of cooling liquid to continuously play a cooling role in waterproof soft synthetic resin packaging bags, and uses the negative heat of solution of sodium sulfate decahydrate and other three salts of cooling liquid to play a cooling role.

Raw materials? 1. Sodium sulfate decahydrate? Commonly known as mirabilite, 2. Ammonium hydrogen sulfate, 3. Sodium bisulfate, 4. Ammonium nitrate The component A (sodium sulfate decahydrate) and the component B (ammonium bisulfate, sodium bisulfate and ammonium nitrate) are respectively put into soft plastic bags or plastic bags to obtain the finished chemical ice pack. When in use, it is rubbed by hand to make the two components A and B in the bag contact, thus playing the role of cooling. It can be used for medical care (such as cooling, stopping bleeding and relieving pain), or for short-term preservation of food, or for low-temperature transportation or carrying of drugs and fresh products. , the effect is very good. Considering the volume, weight, cooling temperature and duration of this medicine, it is especially suitable for medical care.

This kind of ice pack takes effect quickly and can cool down quickly, but it lasts for a short time (of course, the bigger the ice pack, the longer it takes) and cannot be used repeatedly.

The other is physical refrigeration, that is, the ice pack can be used after freezing and can be used repeatedly. There are many styles of this kind of ice pack. Water, water, ethanol and gel can all be used as cold storage agents. The following are introduced respectively:

1. water, which is actually ice;

2. Water and ethanol, with different proportions, release cold energy at different rates, so it can be kept cool for a period of time, and the snow always melts when cooling, which is mild. Compared with ice, it stores more cold, releases cold slowly and lasts for a long time.

3. The gel type is complicated, and the formula is basically from the manufacturer. I didn't find it. Its principle is to use high energy storage materials, such as polyvinyl alcohol and other polymer materials, and add crosslinking agents, such as CMC, to form gel, bag it, use it after freezing, and feel soft when melting. This product is characterized by high energy storage and long maintenance time (depending on energy storage materials)

The use of ice packs

Generally, ice packs can be cold or hot.

Hot compress:

Method 1: Add enough water into the pot and soak the dressing bag. After the water boils, remove the pot from the stove, soak the dressing bag (small 1 minute, medium and large for 2 minutes), dry it and put it into a binding bag for later use. Do not directly heat the cosmetic bag after taking it out of the refrigerator. Don't tie the binding bag too tightly to avoid burns.

Method 2: Put the spread bag in an 850-watt (high-fire) microwave oven and heat it (small 15 seconds, medium 35 seconds, large 50 seconds), and rub the bag to heat it evenly. If necessary, add a hot compress bag every five seconds (the total length of the small size is no more than 35 seconds, the medium size is 75 seconds, and the large size is 2 10 seconds). Don't heat it in the baking tray oven.

Cold compress: put it in a refrigerator at-18℃ for at least 1 hour, put the cold compress bag into a binding cloth bag, and use it for no more than 20 minutes, and then use it again after 20 minutes.

Note: Do not put the compress bag directly on the skin, but always use a tie bag. Only adults, children or people with cognitive impairment should use it under supervision. If you feel uncomfortable or allergic, please stop using it immediately. If the compression bag is broken, do not use it. Please don't use compress when sleeping.

Can the ice pack be used multiple times?

Disposable type

Is the standard process ice-side high-density plastic? One side is non-woven fabric

Mainly used for perishable products, biological agents and all products that need to be refrigerated and transported (if transported? When the technical ice is transported with the product, it cannot be taken back for reuse. It is recommended to use standard two layers of ice. Although the standard technical ice is designed for one-time use, it can be used many times if it is used carefully (note: but it can't be compared with HDR four-layer technical ice. HDR four-layer technical ice? Reusable, hot and cold).

Reusable type

The four-layer technology ice is composed of two layers of non-woven textile materials, combined with the trade secret formula. Concentrated into a special form of crosslinked polyacrylic acid polyol polymer refrigerant. Where is it? The two plastic layers that play a key role use unidirectional microperforation technology to combine the plastic layers. Remove the textile material layer to ensure that this new model can withstand the worst weather during transportation. This performance is undoubtedly an innovation.

1, ice pack is an upgraded product of ice, with stronger applicability, convenient use and health. Healthy and versatile.

2, used for medical high fever cooling, anti-inflammatory and analgesic, cold compress beauty, sprain, hemostasis, suppuration,? Auxiliary physiotherapy such as skin care.

3. Refrigerate and transport all kinds of biological freezing reagents, such as solder paste, poultry medicine, medicines, plasma, vaccines and aquatic products? Long-distance refrigerated transportation of poultry, ornamental fish and foreign trade fresh-keeping food.

4. Used for external bumps, sprains, falls, etc. during the training and competition of sports athletes.

5. Save electricity by storing cold energy in daily life, keep the temperature low when the refrigerator is out of power, keep food fresh and cool drinks. Travel to carry.

6、? Its effective cooling capacity is six times that of the same volume of ice.
