Is the cup that cools quickly healthy? Is the cup that cools when shaking harmful to human body?

1, this kind of fast cooling water cup is called 55-degree fast cooling cup. Pour 100 degree boiling water into the cup and shake it for about one minute, and it will become warm water of about 55 degrees, especially suitable for people who want to drink warm water immediately. For impatient people, don't design cups for special convenience. A 55-degree glass is harmless to the body.

There is actually an interlayer in the middle of the 2.55-degree cup, and the phase change material in the interlayer can absorb heat. This phase change material is a solid with a phase change temperature of 55℃. When people pour boiling hot water into a cup and shake it for at least one minute, the phase change material in the cup quickly absorbs heat and becomes liquid, and the water temperature in the cup drops sharply, thus realizing the cooling function.

3. Temperature at which phase change materials can be stored. As soon as cold water is poured, the heat of the phase change material is absorbed and changed back to solid state, and the water temperature will rise, which is actually a very simple physical change.

4. So the principle of 55-degree cup is actually an ordinary physical change, just a process of heat transfer, which is harmless to human body.
