1, common ice: liquid water freezes to make solid water.

2, stainless steel ice: made of 304 stainless steel, will not dissolve in water to affect the taste. It contains special frozen liquid, which lasts longer than traditional ice cubes.

Second, the principle is different.

1, ordinary ice: pure water in nature will freeze to 0 degrees Celsius at normal atmospheric pressure. If water contains impurities, the freezing point of water will decrease with the increase of pressure. The melting point of ice is the freezing point of water. With the increase of atmospheric pressure, the melting point of ice increases.

2, stainless steel ice: using the principle of physical cooling, it can be used indefinitely and is easy to clean. The harm of ice cubes made from unclean water sources to human body is completely avoided.

Extended data:

The role of stainless steel ice cubes and ordinary ice cubes;

1, relieve hematoma

During the collision, when a hematoma is caused by injury to a certain part of the body, do not apply hot compress, and quickly wrap the wound with ice cubes and clean cotton cloth in the refrigerator. Stimulation of the injured part by cold ice will cause vasoconstriction, which can not only reduce skin bleeding, but also reduce hematoma, and has a good analgesic effect.

However, it should be noted that ice can be applied for a few minutes without repeated cold compress. In other emergencies, ice can also be used to stop bleeding.

Step 2 stop itching

Rubbing the itchy place with ice cubes can stop itching. After being bitten by poisonous insects, besides drug treatment, you can also use ice cubes to relieve itching.
