Thermos insulated water bottle is simply a water bottle that can be insulated. Many businesses say that the thermos insulated water bottles they sell are made of two layers of stainless steel, so many people think that the thermos insulated water bottle can be insulated by two layers of stainless steel. But it's only superficial knowledge. The reason why thermos insulated water bottle can keep warm actually has a deeper secret.
Thermos insulated water bottle is a kind of high vacuum vessel with one millionth of air pressure between two layers of stainless steel. This kind of vacuum state is the same as that of space, which can not carry out any heat convection and heat dissipation. In addition, a mirror function is added in the bottle, which can effectively prevent the heat loss caused by radiation. It is because of this "vacuum layer" that the thermos insulated water bottle can continuously achieve the functions of heat preservation and cold preservation.
To make a good heat preservation cupthermos insulated water bottle, it is necessary to use food grade 304 stainless steel, and it also needs three to seven different degrees of stretch forming, so as to ensure the quality basis from the material and technology. From raw materials to finished products, there are at least 16 processes, so it is not so easy to produce a thermos insulated water bottle.
Finally, the author points out that it is necessary to avoid collision and impact in the daily use of thermos insulated water bottle, so as to avoid damaging the bottle body, causing heat preservation failure or water leakage, otherwise no matter how good the thermos insulated water bottle is, it can not withstand such impact.
