說明書
First, the outer glass plate 11 and the inner glass plate 12 will be described. Known glass plates can be used as the outer glass plate 11 and the inner glass plate 12, and these glass plates can also be made of heat-ray absorbing glass, regular clear glass or green glass, or UV green glass. However, the glass plates 11 and 12 are required to attain a visible light transmittance that conforms to the safety standards of a country in which the automobile is to be used. An adjustment can be made so that the outer glass plate 11 ensures a required solar absorptance and the inner glass plate 12 provides a visible light transmittance that meets the safety standards, for example. An example of clear glass, an example of heat-ray absorbing glass, and an example of soda-lime based glass are shown below.
Clear Glass
-
- SiO2: 70 to 73 mass %
- Al2O3: 0.6 to 2.4 mass %
- CaO: 7 to 12 mass %
- MgO: 1.0 to 4.5 mass %
- R2O: 13 to 15 mass % (R represents an alkali metal)
- Total iron oxide (T-Fe2O3) in terms of Fe2O3: 0.08 to 0.14 mass % Heat-Ray Absorbing Glass
