Insulation cup from the thermos bottle of the development, the principle of insulation as a thermos bottle, people just for the convenience of the bottle made of glass. Heat transmission has three ways: radiation, convection and transfer.Heat preservation cup silver cup liner can radiation reflection hot water, vacuumcup liner and a cup body can block heat transfer, and is not easy to block theheat convection can transfer heat bottles. Thermos bottle now, also the application of magnetized water principle, is at the bottom of the bottle and the bottle cap with a magnet, so that the water is magnetized.
