What's in the ice pack? This summer is no longer hot.

In the hot summer, what people want is to keep themselves cooler and have a weapon of their own. Now this is no longer a luxury. Have an ice pack that can be used not only as a cold compress but also as a hot compress. It is also very convenient and effective to use. But what is inside the ice pack? What substance has such a magical effect? ??Today, let me introduce to you what is inside the ice pack.

What is inside the ice bag

Chemical ice bag: This product is packaged in a water-impermeable soft synthetic resin bag, using component A of the coolant (sodium sulfate decahydrate). The portable chemical ice pack, which continuously exerts a cooling effect, uses the negative heat of dissolution of the chain reaction of the coolant sodium sulfate decahydrate with the other three salts to produce a negative dissolution heat of chain reaction with the three components in Group B. Provide cooling effect.

Raw materials? 1. Sodium sulfate decahydrate? Commonly known as Glauber's salt, 2. Ammonium bisulfate, 3. Sodium bisulfate, 4. Ammonium nitrate?, Component A (sodium sulfate decahydrate) is the same as group B The components (ammonium bisulfate, sodium bisulfate and ammonium nitrate) are packaged in soft plastic bags respectively, or individually packaged in a plastic bag to obtain the finished chemical ice bag. When using, knead it with your hands so that the two components A and B in the bag come into contact to exert a cooling effect. It can be used for medical care (such as cooling, reducing fever, stopping bleeding, and relieving pain), or for short-term preservation of food, or for low-temperature transportation or carrying of medicines and fresh products, etc., and has good effects. Especially for medical care, it is extremely suitable considering the volume, weight, cooling temperature and duration of this agent.

This type of ice pack works quickly and can cool down quickly, but the maintenance time is short (of course, the larger the ice pack, the longer it will take), and it cannot be used repeatedly.

The other is physical refrigeration, which is to freeze the ice pack before using it. This can be used repeatedly. There are many styles of this kind of ice pack, and it can use water, water and ethanol, gel, etc. as a cold storage agent. Let’s introduce them respectively:

1. Water, which is actually ice cubes;

2. Water and ethanol. Water and ethanol release cold energy in different proportions. The speed is different, and it can be kept cold for a period of time. When it is cooled, it always maintains the shape of melted snow, which is relatively gentle. It stores more cold than ice, releases it slowly and lasts longer.

3. The gel type is more complicated, and the formula is basically the manufacturer’s own, and I couldn’t find it. The principle is to use high-energy-storage materials, such as polyvinyl alcohol and other polymer materials, and add cross-linking agents, such as CMC, to form a gel, pack it in bags, and use it after freezing. It will feel soft when melted. This product is characterized by high energy storage and long maintenance time (it will vary depending on the energy storage material)

How to use ice packs

Generally, ice packs can be used for hot and cold compresses

Hot compress:

Method 1: Add enough water to soak the compress bag in the pot, wait until the water boils, remove the pot from the stove, and soak the compress bag (small size is 1 minute , 2 minutes for medium and large), dry it and put it into a bandage bag for use. Do not heat the compress bag directly after taking it out of the refrigerator. Do not tie the bandage bag too tightly to avoid burns.

Method 2: Flatten the compress bag and heat it in an 850-watt (high heat) microwave oven (15 seconds for small size, 35 seconds for medium size, 50 seconds for large size), and rub the compress bag , for uniform heat, if necessary, heat the compress bag again every five seconds (the total time should not exceed 35 seconds for the small size, 75 seconds for the medium size, and 210 seconds for the large size). After heating is completed, put it into the strapping bag for use. Do not use baking pan for oven heating.

Cold compress: place it in a refrigerator at -18 degrees Celsius for at least 1 hour, place the compress bag in a bundled cloth bag, do not use it for more than 20 minutes, and use it again after an interval of 20 minutes

Note: Do not place the compress directly on the skin, always use a bandage. For adult use only, use under supervision by children or people with cognitive disabilities. If you feel uncomfortable or allergic, please stop use immediately. If the compress bag ruptures, do not use it. Do not use the compress while sleeping.

Can the ice bag be used multiple times

Disposable type

Standard technology ice has one side made of high-density plastic and one side made of non-woven fabric

Mainly used for perishable products, biological preparations and all products that need to be refrigerated for transportation (if the scientific ice is transported with the product during transportation and cannot be recovered for reuse, it is recommended to use the standard two-layer one)? Standard type Although the Tech Ice is designed for one-time use, it can be used multiple times with careful use (Note: However, it cannot be compared with the HDR type four-layer Tech Ice. The HDR type four-layer?, can be used repeatedly. Hot and cold dual use).

Reusable

Four-layer Tech Ice consists of two layers of non-woven textile material, which are combined with trade secret formulas and compressed into a special form of cross-linking. Polymer refrigerant of polyacrylic polyol. The two key plastic layers inside use unidirectional micro-perforation technology to bond the plastic layer to the textile material layer, ensuring that this new model can withstand the worst weather during transportation. This performance It is undoubtedly an innovation.

1. Ice bags are an upgraded alternative to ice cubes. They have more applicability, are easy to use, hygienic and have a wide range of uses.

2. Used for medical treatment of high fever cooling, anti-inflammatory and analgesic, cold compress beauty, sprain, hemostasis, suppuration, skin care and other auxiliary physical therapy

3. Refrigerated transportation of various biological freezing reagents , Long-distance refrigerated transportation of solder paste, poultry medicine, medicines, plasma, vaccines, aquatic products, poultry, ornamental fish and foreign trade fresh food.

4. It is used for accidental bruises, sprains, falls, etc. during the training and competition of athletes in the sports world.

5. Cold storage saves energy in daily life, maintains low temperature when the refrigerator is powered off, keeps food fresh, iced drinks, and can be carried during travel.

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

Ice bag manufacturer

Shanghai Jingkun Industrial Co., Ltd. was established in 2011 and is located in Xinqiao Industrial Park, Xinqiao Town, Songjiang District, Shanghai. It is a company specializing in cold and hot products and is committed to Private enterprise engaged in R&D, production, processing and sales of physical cooling and warming products, mainly including disposable quick-cooling ice packs, biological ice packs, cold compress physiotherapy bags, hot compress physiotherapy bags, hot and cold compress physiotherapy bags, disposable instant heat bags, metal Hot bags, multi-purpose cooling pads (pet cooling pads, car cooling pads, sofa and sleeping cooling pads), iron powder hot bags (commonly known as baby warmers, instant heating pads), cold chain ice box ice bags, etc.
