Principle of stainless steel thermos bottle

Stainless steel thermos bottle has gradually become the first choice of friends in winter, because of its unique heat preservation function, it is deeply loved by people and businesses. But many people don't know why the thermos bottle can keep warm. The following is the principle of the heat preservation of the stainless steel thermos bottle:

The stainless steel thermos bottle, in fact, is to extract the air between the two layers of stainless steel in the cup to make it into a vacuum environment, so as to achieve the purpose of heat preservation. The length of the heat preservation time also depends on the structure of the bottle body and the thickness of the bottle material, that is to say, the thinner the thermos bottle material is, the longer the heat preservation time is.

The thermos bottle with large capacity and small mouth has a longer heat preservation time, on the contrary, the thermos bottle with small capacity and large mouth has a shorter heat preservation time. Some manufacturers will add metal film and copper plating on the outer layer of the thermos bottle inner liner to increase the heat preservation time.

Everyone would not think that a small insulation function would have such a tedious process. At the same time, here is a small suggestion: because the bottle body of the thermos bottle is made of stainless steel, it is very easy to be damaged and deformed, so when using the stainless steel thermos bottle, we must try not to let the thermos bottle fall or be hit violently. Otherwise, the heat preservation function of the thermos bottle may fail.
