Evaluation of the interaction of solar radiation with colored glasses and its thermal behavior
Source abstract
Abstract
Solar irradiation can induce different process on glasses. In this study, the thermal behavior of colored glasses (colorless, red, yellow, green, turquoise, blue, purple, and brown) were characterized by UV-vis-IR spectrophotometry, thermal conductivity-meter, infrared thermocamera and dilatometry. The calculation of the absorption coefficients and the thermal conductivity showed that the heating of each fragment depends predominantly on the chromophores. Blue, green and turquoise glasses present the highest NIR absorption, thermal conductivity, thermal expansion coefficient and the largest heating curve. In comparison with colorless glass, the expansion coefficient of bluish glasses is > 5·10−7°C−1 that can produce a thermal incompatibility with the formation of fissures and detachments.
