The stainless steel double-layer thermos cup can keep hot water and cold water warm. The principle of heat preservation is to remove the air between the double-layer shells through vacuum technology to form a vacuum state to prevent temperature conduction. Therefore, the stainless steel double-layer thermos Regardless of whether hot water or cold water is filled in the thermos cup, the surface temperature of the water cup is the natural ambient temperature, and will not change due to the temperature of the drink in the cup. Therefore, the stainless steel thermos cup is filled with ice water, and the surface of the water cup will not cause water condensation due to low temperature conduction.
Since the finished product is a good product, the double-layer stainless steel thermos cup can play a good role in heat insulation, and there will be no condensation beads on the surface after being filled with cold water, so since the condensation beads appear, it means that the water cup has not been able to isolate the temperature conduction If you buy such a water cup, it is recommended that you contact the merchant in time to provide product problems and ask the other party to provide return and exchange services.
