Do you know the most common glass thermos in our life?

Glassware is a necessity in our lives. Without it, our life will be very inconvenient. Do you know the insulation principle of glass thermos? When the glass thermos has dirt, how can we clean it? This article will be introduced.

1)How to remove the scale of the glass thermos

1) Use lemon

Can't think of it? Lemon can also be used to remove dirt. We only need to chop the lemon first, then put it in a glass thermos with hot water, and let it stand for a while, the dirt will be gone. In fact, the cleaning agent we use in normal times, the main component is citric acid.

2)The principle of insulation of glass thermos

In fact, it is not difficult to understand the principle of insulation of glass thermos. The main reason for the insulation of glass thermos is that the glass thermos is a double-layered glass structure. There is a vacuum between the inside glass and the outside glass. At the same time, the outer glass is blocked with a layer of silver or aluminum. Because of the silver-plated glass, the heat dissipation of the glass is weakened. So this is why the glass thermos can be kept warm. If the thermos is filled with cold water, the principle of maintaining the temperature is the same.

But for thermos, there is a disadvantage. That is, the bottle neck portion of the bottle is likely to cause heat to diffuse, which will reduce the thermal insulation performance of the thermos bottle. In order to have better insulation performance of the thermos bottle, it is generally preferred to shorten the bottle neck portion of the thermos bottle.
