Do you know how to choose a Thermos Bottle in winter(1)?

Winter is approaching, friends at home will always keep a thermos bottle so that they can drink hot water at any time. School students also have their own Thermos Bottles, but some students do not know how to choose insulation pots, so there are often accidents of insulation pot explosions. So how to choose?

 

First choose the thermos bottle to choose from the following six aspects

 

1. Capacity

In general, the capacity of the heat preservation pot is between 1.5L and 2L. It is good to choose the appropriate capacity according to your needs.

 

2. Liner

 

The most common thermos bottles on the market are made of stainless steel and glass.

 

1. Stainless steel heat preservation pot: Stainless steel heat preservation pot is the most common kind of heat preservation pot on the market. The cost and price of this kind of heat preservation pot are not high, but the heat preservation effect is better and it has a high cost performance. The stainless steel inner pot used in the stainless steel insulation pot is generally made of food grade 304 stainless steel, otherwise the stainless steel insulation pot is not up to the standard. The stainless steel used in the inner tank of the high-grade stainless steel insulation pot is generally made of food-grade 304 stainless steel, while the low-quality stainless steel insulation pot is made of 201 stainless steel. There is iron element in the inner pot of stainless steel heat preservation pot, which is one of the elements we need to take in daily.

 

2. Glass thermos bottle: Glass thermos bottle is also a common type of thermos bottle. The glass thermos bottle is safer than other materials, because the glass liner of the glass insulation pot is artificially blown. The physical and chemical properties of this material are relatively stable, and it is not easy to produce and use. Undesirable impurities are produced, which will not affect human health, and glass heat conduction is slower, and the silver-plated glass liner can effectively reduce external heat radiation, so the glass liner thermos keeps better.
