Everyone knows that the vacuum layer between the inner wall and the outer shell of the vacuum flask can keep warm. There is no medium to spread in the vacuum, the heat will not diffuse, and the outside air-conditioning can't transfer the temperature of the water in the cup. This is the vacuum cup The most basic principle of heat preservation, the term "double layer" of double glass cups is easy to mislead consumers, but there is no vacuum in the middle of the double layer, and the double layer can only play a role in preventing heat insulation, and there is no heat preservation that can be achieved by a thermos cup. effect.
Compared with ordinary glasses, double-layer glasses have many unique functions. Let's take a look at what they have.
1. The design of the double-layer glass cup will greatly reduce the thermal conductivity of the cup and play a role in preventing heat insulation during use.
2. By applying the principle of dual structure, the comfort of the cup is improved, and the heat preservation effect of the glass is improved.
3. The double-layer glass cup is not only a humanized design, but also has a very good aesthetic value. The combination of transparent production materials and a double-layer structure sublimate the water for making tea into a dynamic artistic act.
4. The double-layer glass has the function of heat preservation and heat insulation, and can also store ice cubes.
5. Since the inner layer and sealing of the lid meet the medical-grade safety standards, leakage can be effectively prevented.
