Two reasons why a Double Wall glass will keep warm.
Now the Double Wall glass is widely used. It not only has the anti-scalding function, but also has a certain heat preservation effect. The following is a brief introduction to the reasons why double-glazed glass will keep warm.
First of all, the reason why Double Wall glass is insulated is because it adopts vacuum insulation technology. In the case of vacuum, it can prevent heat from being transferred to the outside, so as to achieve the effect of heat preservation. In fact, this is also the reason why it is anti-scalding. In addition, there is usually a slight heat at the mouth of the Double Wall glass, and the temperature will also be lost from here.
In addition, the airtightness of the Double Wall glass also contributes to its heat preservation effect. The better the airtightness, the better the natural heat preservation effect. Therefore, when buying a Double Wall glass, you need to pay special attention to check its tightness. You can twist the lid to check whether the lid is completely consistent with the body and whether the lid has a sealing ring. During the test, you can do a test, pour 100 degrees of boiling water into the cup, wait two or three minutes, and then touch each part of the Double Wall glass with your hand to test whether the temperature is hot, and if which part will be If you get hot, the temperature will be lost from that place. However, it is normal for a Double Wall glass to have a slight heat at the mouth of the glass. Then, pour water into the cup, and turn the cup upside down for two or three minutes to see if any water seeps out. If the Double Wall glass does not seep, it indicates that it has good sealing performance.
The heat preservation effect of the Double Wall glass cup is very practical, because it can not only ensure the temperature of the tea, but also prevent it from being inaccessible like a thermos cup.
