The stainless steel insulated water bottles is made of double-layer stainless steel inside and outside. The inner tank and the outer shell are combined by welding technology, and the air in the interlayer between the inner tank and the outer shell is extracted by vacuum technology to achieve the effect of vacuum insulation. Do you want to know more details about it? Let's learn more about the process flow of the stainless steel water bottle.



Features of stainless steel insulated water bottle

The stainless steel insulated tumbler is characterized by a cover on the top and a tight seal. The vacuum insulation layer can delay the heat dissipation of the water and other liquids in the interior to achieve the purpose of heat preservation. The thermos bottle is developed from the thermos. The principle of insulation is the same as that of the thermos, but people make the bottle into a water bottle for convenience. There are three ways of heat transmission: radiation, convection and transmission. The silver water bottle bladder in the thermos can reflect the radiation of hot water, the vacuum of the water bottle bladder and the vacuum water bottle can block the heat transfer, and the bottle that is not easy to transfer heat can prevent heat convection.
