Why doesn't the thermos cup keep warm?

After we have purchased and used it for a period of time, some people may find that the thermos cup has gradually become uninsulated. What is the reason that the thermos cup does not keep warm? The following will be answered by Dongguan Zhanyi Commodity Technology Co., Ltd.

 

The possible reason why the thermos cup is not insulated is that the service life of the thermos cup is up. If we maintain it properly, the service life of a vacuum flask is about 3~5 years. After this period of time, the insulation function of the thermos will slowly degrade, until it finally loses its insulation function.

However, if the insulation cup is not properly maintained during the use of the insulation cup, the service life of the insulation cup will be much shortened, and the insulation effect will become worse. Then if the thermos cup undergoes a relatively violent collision, it is also very likely that the thermos cup will not be insulated. The thermal insulation principle of the vacuum flask lies in its vacuum layer. If it is bumped, it may cause the vacuum layer of the vacuum flask to leak, which will not achieve the effect of preventing heat transfer, and naturally it will not be insulated.

The above points are the main reasons why the thermos cup asks why it is not insulated. Of course, there are some other minor problems that will affect the insulation effect of the thermos. For example, the aging or damage of the sealing parts will also make the sealing of the thermos worse, which will cause the thermos to become less insulated. If you want to extend the use time of the vacuum flask, we need to maintain the vacuum flask.

The vacuum flask produced by Dongguan Zhanyi Commodity Technology Co., Ltd. is made of sufficient materials and exquisite workmanship.
