How to extend the heat preservation time of a thermos bottle?

Hello everyone, "Dong Dong Talks About Cups" is here. The editor found that the number of visits to the newly released videos under the "Dong Dong Talks About Cups" account on several video platforms has increased significantly. Thank you for taking the time to watch the videos released by the editor. These videos are also completed by our team members. http://www.zhanyict.com/en/ProductsDetail-VB-10488.htmlNone of us are professionals, so the video shooting techniques are relatively simple. We have also tried our best in editing. Thank you for your tolerance and support. Today, the editor will continue to share new content with you, how to extend the insulation time of the thermos cup?

This question was raised by readers when I started writing and publishing this article. Over the years, some readers have continued to raise this question. They generally want to know how to extend the insulation time of the stainless steel thermos cup they bought if they find that the insulation time is not as long as they want after using it for a period of time. http://www.zhanyict.com/en/ProductsDetail-VB-10488.htmlI initially thought that this was just a misunderstanding of some friends and did not respond. Later, when I found that many friends had this idea, I responded to everyone today.

Although I have been working in the water cup industry for many years, to be realistic, the insulation time of a finished stainless steel thermos cup that has been produced is fixed. This means that whether the production process of this water cup that has been put on the market is exquisite? Is the production process completed? Is the quality management strict? All of these have determined the insulation time of this water cup. http://www.zhanyict.com/en/ProductsDetail-VB-10488.htmlIf the workmanship is good, the production process is strictly implemented, and the quality control is strict, then the insulation performance of the thermos cup on the market is stable, and the thermos cup market is also in line with the standards. On the contrary, the insulation time of the water cups on the market, even if they are of the same brand, model and capacity, is different.

In addition, everyone has different expectations for the insulation time of a thermos cup, which is why the editor has not responded and written such content. A thermos cup is qualified if it can keep warm for 8 hours according to the national standard. http://www.zhanyict.com/en/ProductsDetail-VB-10488.htmlIn fact, it is found that the insulation time can reach 10 hours during use, but I need this water cup to keep warm for 14 hours or even longer. If this is the idea, let alone extending the insulation time of the thermos cup that has been sold to such a long time through some human intervention, even if the shape and structure of the water cup are not changed during production, it is difficult to achieve through production technology and improving process operation standards.

Next, the editor will give you some suggestions based on the principles of heat preservation and heat dissipation of the thermos cup, hoping that this method can extend the heat preservation time of the thermos cup. The heat preservation principle of the stainless steel thermos cup is to achieve the function of heat insulation by evacuating the gap between the double-layer stainless steel bottle body to better keep warm. http://www.zhanyict.com/en/ProductsDetail-VB-10488.htmlThe hot air rises and because there is no insulation layer at the mouth of the thermos cup, the temperature transfer is blocked by the cup lid. Therefore, most of the heat dissipation of the thermos cup is dissipated through the mouth of the cup, and a small part is dissipated through the cup body, but because the dissipation is relatively slow, it is difficult to detect.

Since the temperature is transmitted from the mouth of the thermos cup, if we want to extend the insulation time of the thermos cup, we should try to reduce the number of times the cup lid is opened, and at the same time, seal the cup mouth more tightly to insulate it. Secondly, try not to use the thermos cup in an environment where the temperature difference between the ambient temperature and the temperature inside the cup is too large. http://www.zhanyict.com/en/ProductsDetail-VB-10488.htmlFor example, the temperature inside the cup is 90℃ and the ambient temperature is minus 40℃, or the temperature inside the cup is minus 1℃ and the ambient temperature is 35℃. Such a large temperature difference will accelerate the temperature loss. The solution is to put on an insulation "outer coat" for the thermos cup. The best filling material in the "outer coat" is insulation material. The more fillings, the better the effect of extending the insulation time.
