This property determines that it has one more use to refract light into the room, but at the same time, glass has another test compared to other materials-light transmittance. ��D]��1Ur�;���G���P^

y���`�|� High-performance windows with low-E coatings can reject the solar heat gain while allowing relatively high amounts of visible light to pass through the glass, however, the more solar gain being filtered out, the less (minimal) the transmittance. /Name /Im9 How to Measure Ultraviolet Radiation Intensity by a UV Lamp Intensity Meter? Tints can also be added to glass to decrease light transmittance. From:Linshang Time:2020/04/06 11:00:00 Browse:145. When the heavy oil is not completely burned, some impurities in the air will enter the glass, which affects the light transmittance of the glass. These materials have a much higher purity than natural minerals and have a small impact on the light transmittance of glass. Arrange more productions to make the molten glass stay in the furnace as short as possible. Factors affecting glass transmittance. (2) The furnace output should be large. d o c)
