Can the broken thermos bottle be used?

Generally, the thermos bottle has the characteristics of anti falling, anti leakage and anti impact, and the service life of the thermos bottle is 3 to 5 years. But in the life of the thermos bottle, it may suddenly appear that the thermos bottle is not insulated. Why? Generally speaking, it may be due to the following reasons: poor sealing, air leakage of the thermos bottle or poor quality of the thermos bottle. In order to improve the service life of the thermos bottle, we should pay attention to some common sense. For example, we can't use the thermos bottle to make tea, and some acidic liquid should not be put into the thermos bottle to avoid releasing toxic substances.

How to repair the thermos bottle?

Although there is no way to repair the thermos bottle if it is not insulated. This is because the vacuum state is damaged by air leakage from the bottle body, the bottle can still be used. Although the holding time is not ideal, it is still in good condition. If it is of special significance to you, you can keep it.

The reason why the thermos bottle does not keep warm.

1. It may be that the sealing is not good. Check whether there is a gap in the cap or other places. If the cap is not tightly closed, the temperature of the water in the thermos bottle will drop quickly.

2. There is air leakage in the bottle body. Maybe there is something wrong with the material of the bottle. Some thermos bottles have defects in technology. Pinhole size holes may appear in the inner liner, which can accelerate the heat transfer between the two walls of the bottle, so that the heat is lost quickly.

3. The thermos bottle is sandwiched with sand. This is a way for some businesses to make thermos bottles with inferior quality. When such bottles are bought, the thermal insulation effect is very good, but after a long time, the sand may react with the tank, causing the bottle to rust, and the insulation effect will be very poor.
