Thermos insulation principle
The principle of thermos insulation means that the cork stopper is used to prevent the convection between hot and cold air; the gap between the double-layer bottles is vacuumed to solve the heat conduction; a thin layer of silver is applied to the bottle. Make it a mirror that reflects light and reflects heat, so that the silver layer is used to block the heat radiation. In this way, heat will not be lost and will play a role in heat preservation.
