How does a thermos cup utilize double glass insulation?

Many people have the experience of using disposable cups to catch very hot water, often with two paper cups so as not to burn their hands. This is the most primitive thermal insulation cup. Since the double glass cup is double, that certainly has the function of heat insulation and heat preservation, many high-rise buildings installed on the floor windows of the double glass, is to play the role of this heat insulation and heat preservation, in addition to both the function of noise isolation. Of course, this double-glass cup than the real meaning of the insulation cup, the function is still slightly lacking, because it is not a vacuum compartment.

If the compartment is vacuumed, and then plated with mercury on the inner layer, it will become a traditional thermos bottle, and the heat preservation effect will be great, however, the aesthetic effect is far worse. So, now this double-layer glass cup is a combination of aesthetic and thermal insulation, and to the aesthetic as the first priority. Double glass cup is the last century, the Japanese first invented, first made two layers of the cup wall, and then the air in it is evacuated, so that the internal stainless steel cup of hot water in the state of pumping into a vacuum will be able to maintain the original water temperature, so that the cup is not only heat preservation, but also to keep the cup wall at a low temperature, so that we will not be high temperature heat conduction when we use it to facilitate the drinking of water.

Double glass since it is a double layer, that certainly has the function of heat insulation, many high-rise buildings installed on the floor windows of the double glass, is to play this role of heat insulation, in addition to both noise insulation function. Of course, this double-glass cup than the real meaning of the insulation cup, the function is still slightly lacking, because its compartment is not a vacuum. If the compartment is vacuumed, and then plated with mercury on the inner layer, it becomes a traditional thermos bottle, and the insulation effect is great, however, the aesthetic effect is far worse.

Double glass, as the name suggests, is a two-layer glass firing connection and become, with heat insulation and anti-scald function, so it is a good solution to the problem of single-layer glass hot, is more healthy drinking water containers.
