Ultraviolet/infrared absorbent low transmittance glass |
摘要 |
<p>The ultraviolet/infrared absorbent low transmittance glass consists of base glass including: 65 to 80 wt.% SiO2; 0 to 5 wt.% Al2O3; 0 to 10 wt.% MgO; 5 to 15 wt.% CaO (a total amount of MgO and CaO is between 5 to 15 wt.%) ; 10 to 18 wt.% Na2O; 0 to 5 wt.% K2O (a total amount of Na2O and K2O is between 10 to 20 wt.%) ; and 0 to 5 wt.% B2O3; and colorants including: 1.2 to 2.2 wt.% total iron oxide (T-Fe2O3) expressed as Fe2O3; greater than 0.03 wt.% CoO; less than 0.0001 wt.% Se; and 0 to 0.2 wt.% NiO. The glass has a visible light transmittance measured by the illuminant A of not greater than 12 % in case that the glass has a thickness of 4mm. The glass has almost neutral color such as bluish green shade or deep green shade, low visible light transmittance, low solar energy transmittance and low ultraviolet transmittance, so that it is useful for windows of vehicles or buildings particularly for thickness and weight reduction of a privacy preventing glass.</p> |
