Why can heat preservation vacuum flask
Third, the inside of the double deck glass evenly on the surface of the plating Layer of silver, silver plated shining surface, can reach the thermal radiation on the surface of the back, thus preventing the damage because of the thermal radiation Heat loss. The vacuum flask to heat preservation, because inside on the structure of the three major characteristics, basic to prevent the heat dispersion Loss of three ways: convection, conduction and radiation. In the same way, we will be cold in your vacuum flask, can also Cold insulation effect, become a cold bottle
Second, the inside by double Glass, glass and cork is a poor conductor of heat, interlayer distance is only 8 mm, is pumped in the sandwich Into the vacuum, can effectively prevent heat conduction.
Inside of the vacuum flask on the structure has three characteristics: first, the inside of the smaller bottle, bottle mouth sealed cork stopper , which can reduce evaporation, to prevent the flow of gas, liquid surface to reduce heat loss.
