What's in the ice pack?
Chemical ice pack: This product is a portable chemical ice pack that continuously plays a cooling role in a waterproof soft synthetic resin packaging bag by using the negative heat of dissolution of component A (sodium sulfate decahydrate) of the coolant and three components in group B. It plays a cooling role by using the negative heat of dissolution of sodium sulfate decahydrate of the coolant and three other salts.
Raw materials? 1. Sodium sulfate decahydrate? Commonly known as mirabilite, 2. ammonium bisulfate, 3. sodium bisulfate, 4. ammonium nitrate? , the component A (sodium sulfate decahydrate) and the component B (ammonium hydrogen sulfate, sodium hydrogen sulfate and ammonium nitrate) are respectively packed in soft plastic bags, or are separately packed in a plastic bag to obtain the finished chemical ice pack. When in use, it is kneaded by hand to make the two components A and B in the bag contact, so as to play a cooling role. 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, etc., and has good effects. It is especially suitable for medical care, considering the volume, weight, cooling temperature and duration of this agent.
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 will take), and it can't be used repeatedly.
The other is physical refrigeration, that is, the ice pack is frozen and then used, which can be used repeatedly. There are many styles of this kind of ice pack, and water, water and ethanol, gel and so on can be used as cold storage agents. The following are introduced separately:
1. water, which is actually ice;
2. Water and ethanol, with different proportions, have different rates of releasing cold energy, so they can keep cooling for a period of time, and always keep the snow melting when cooling, which is gentle. Compared with ice cubes, it stores more cold, releases cold slowly and lasts for a long time.
3. The gel type is complicated, and the formula is basically owned by 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 a 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)
Usage of ice pack
Generally, ice packs can be cold and hot.
Hot compress:
Method 1: Add enough water to the pot to soak the dressing bag. When the water boils, remove the pot from the stove, soak the dressing bag (1 min for small size, and 2 minutes for medium size and large size), dry it and put it into a binding cloth bag for use. Do not directly heat the dressing bag after taking it out of the refrigerator. Do not bind the binding cloth bag too tightly to avoid burns.
Method 2: Put the bag spread flat in an 850-watt (high-fire) microwave oven for heating (15 seconds for trumpet, 35 seconds for medium and 50 seconds for large), and rub the bag to evenly heat it. If necessary, add the hot compress bag again every five seconds (the total duration of trumpet should not exceed 35 seconds, medium 75 seconds and large 2 10). Do not use the baking tray oven for heating.
Cold compress: put it in the refrigerator at-18℃ for at least 1 hour, put the compress bag in 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, always use a binding cloth bag. Adults only, children or people with cognitive impairment should use it under supervision. If you feel uncomfortable or allergic, please stop using it immediately. Do not use if the compress bag is broken. Please don't use the compress when sleeping.
Can the ice pack be used multiple times?
Disposable type
Is the standard technology 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 technology ice is shipped with the product, it can't be taken back for reuse. It is recommended to use the standard two-story ice. Although the standard technical ice is designed for one-time use, it can also 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 consists of two layers of non-woven textile materials, which are combined with the trade secret formula. Condensed into a special form of cross-linked, polyacrylic polyol polymer refrigerant. In there? The two plastic layers that play a key role use one-way micro-perforation technology to combine the plastic layers. Go to the textile material layer and make sure that this new model can withstand the worst weather during transportation. This kind of performance is undoubtedly an innovation.
1, ice pack is an upgraded substitute product of ice, which has more applicability, convenient use and health. Health, a wide range of uses.
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 sports athletes training and competition in the process of external bumps, sprains, falls, etc.
5. Store cold energy and save electricity in daily life, and maintain low temperature, keep food fresh, and cool drinks when the refrigerator is out of power. Travel to carry.
6、? Its effective cold capacity is 6 times that of the same volume of ice.
