How long can the thermos be used? How long does it take to qualify as an insulated mug?（two）

The sealing ring used as the sealing function between the lid and the body of the cup is currently mostly silica gel. Silicone is elastic and has a limited lifespan, plus prolonged soaking in hot water. Under normal circumstances, the silicone sealing ring needs to be replaced once a year, which means that the safe service life of the silicone sealing ring is about 1 year.

Through the life analysis of each part of the thermos cup, a qualified thermos cup can be used for at least one year if used properly. But according to the editor, it is no problem to use a thermos cup with excellent workmanship and quality for 3-5 years.

So how long does it take to be a qualified thermos? Considering the safety of the silicone ring, it takes at least 1 year for a thermos to go from the factory to the replacement of accessories. Therefore, if a thermos cup has problems such as poor performance and no insulation after less than 1 year of use, it means that this thermos cup is unqualified.

Finally, the editor answered the question of how long we need to replace the thermos cup in our daily use. How long it is used is not determined by the long life of the thermos cup, and how long it is used mainly depends on the user's usage habits. The editor has seen that it will be replaced after two or three months of use, and I have also seen those that have been used for 5 or 6 years and continue to be used.I give you some advice. If you use a thermos cup, it is only filled with cold or hot water, and the whole cup will be cleaned in time after use. In the case that the materials are qualified and the workmanship quality is guaranteed, there is no problem in using it for 5 or 6 years.

But if you use it every day, you will hold a variety of different types of drinks, coffee, juice, alcohol, etc.At the same time, it cannot be cleaned in time after use. In particular, some friends forget that there is still unfinished drink in the water cup after using it, causing mildew inside the water cup. The editor recommends that such a friend replace it every two or three months.There was a mildew in the water cup.

Although high temperature or sterilization can completely kill viruses, this will damage the inner liner of the water cup. The most obvious phenomenon is the oxidation of the inner liner of the water cup. Once the liner of the water cup is oxidized, the service life will be greatly shortened, and the oxidized liner will also cause harm to the human body when it is used. If such a thing occurs 2 or more times, the editor recommends replacing the thermos with a new one in time.
