The insulated water bottle is almost a necessary product in our daily life. Whether it is used for heat preservation or cold preservation, it is very popular.
The bladder of the insulated insulated water bottle is made of double-layer glass. Both layers of glass are plated with silver, like a mirror, which can reflect the heat rays back and cut off the path of heat radiation.
The vacuum between the two layers of glass in the thermos destroys the conditions of convection conduction. The use of a heat preservation water bottle lid that is not easy to transfer heat cuts off the path of convection and heat transfer.
If all three roads for heat transfer are blocked, the heat can be retained for a long time. However, the thermal insulation of the thermos is not so long.There is still some heat that can come out, so the thermal insulation time of the thermos has a certain limit.
The lid of insulated water bottle can maintain the temperature of the water in the bottle, cut off the exchange of cold and heat between the bottle and the outside of the bottle.
If you put ice in the thermos quickly, the heat outside will not run into the bottle easily, and the ice will not melt easily.
The insulated water bottle is very useful,which can save both heat and cold.
