Dark green gray low permeability glass composition

摘要

The present invention relates to a low-transmission dark mist green glass composition, more specifically relates to a low-transmission dark mist green glass composition in which Fe 2 O 3 , CoO, Se and Cr 2 O 3 are used as coloring components within a specific content range where for the coloring components the relative contents of (CoO+Cr 2 O 3 ) to Se and CoO to Cr 2 O 3 are restricted to certain ranges and accordingly the visible transmittance (LT A ) is effectively controlled and thus a blocking performance for privacy is satisfied; the solar energy transmittance (T e ) and the UV transmittance (T uv ) are lowered, and accordingly the cooling load for vehicles, buildings and the like is reduced and interior materials and people protection against UV rays is obtained; and the optimal range of chromaticity diagram of transparent colors is satisfied which accordingly reduces eyestrain and provides psychological stability.
