What is the heat preservation principle of a thermos cup? Can it achieve extra-long heat preservation?

Hello everyone, "Dong Dong Talks About Cups" is here. Yesterday, the editor shared the principle of heat preservation of the glass liner of the traditional glass thermos kettle. Interested friends can look through the editor's article yesterday. Today, the editor brings friends "What is the heat preservation principle of the thermos cup? Can it achieve super long heat preservation?" Friends who like the editor's articles, please follow the editor. http://www.umbottle.com/ProductsDetail-VB-10053.htmlThe editor hereby declares that all the articles written and published by the editor are articles written by the editor personally. The editor owns the copyright of the copywriting. Friends who like the editor's articles can forward them, but please do not delete or add without authorization to mislead everyone. Recently, I saw an article on a certain website that deleted and added to the editor's article, and the content changed. The undeleted parts have the same typos as the editor's original text. This behavior is really despicable.

Friends who have been following my account for such a long time must have understood the insulation principle of a thermos bottle. http://www.umbottle.com/ProductsDetail-VB-10053.htmlHowever, there are still some new friends or tourists who are not clear about it. If you are also interested, I will continue to share with you the insulation principle of a thermos bottle.

The ability of a thermos cup to keep warm means that it can lock in the temperature. The longer the temperature is locked in, the longer the heat preservation time is. Here, heat preservation refers to both heat preservation and cold preservation. http://www.umbottle.com/ProductsDetail-VB-10053.htmlThe principle of heat preservation is that all factories currently use a double-layer structure for the cup body, and the air between the double layers is discharged through high temperature and pressurization to form a vacuum state, that is, vacuumization. Since the temperature required for high temperature and pressurization must reach 600℃, the materials that can be used to make thermos cups are mainly metal and glass. In the previous article, the editor talked about the production method and material use of glass water cups, which made it impossible to achieve vacuumization, so the thermos cups you see on the market are mostly made of stainless steel and titanium.

Many friends are concerned about the insulation time of thermos cups, and some friends also asked if there are any thermos cups that can achieve super long insulation? http://www.umbottle.com/ProductsDetail-VB-10053.htmlBefore explaining super long insulation, let us first know what is the current national standard for insulation of thermos cups? Any product is subject to national standard specifications, and the same is true for thermos cups. The national standard stipulates that the insulation time of a thermos cup is determined by the size of the thermos cup, that is, the capacity, the diameter of the thermos cup mouth, and the way the lid and the cup body of the thermos cup fit together. The editor concluded that the insulation time of a qualified thermos cup should be 6-12 hours. This is a range that includes a variety of cup types and a variety of national standard conditions. Since the content is very detailed, the editor can only summarize it relatively. You can see that the insulation time requirements of the thermos cup are roughly like this. With this time requirement, it is easy to talk about super long insulation.

Taking the thermos cup that keeps heat for 6 hours as an example, the super long heat preservation time should be about 10-12 hours, that is, the super long heat preservation time is usually nearly double the heat preservation time specified by the national standard. http://www.umbottle.com/ProductsDetail-VB-10053.htmlSome friends may ask, is it possible to improve the production quality of the thermos cup that keeps heat for 6 hours as specified by the national standard so that the heat preservation time can reach 24 hours, 48 hours or even longer through strict production management? To be sure, this is impossible. The production of any product has a reasonable value, and the same is true for thermos cups.
