REXI green glass is a kind of selective absorption type glass. It only transmits or absorbs light in one or several wavelength bands. Its characteristic is that the transmittance curve has obvious peaks and troughs in the whole spectral range.
The coloring matter used in Chinese factory is a transition metal element such as titanium, vanadium, chromium, manganese, iron, cobalt, nickel, copper, etc. The valence electron transitions between different energy levels (ground state and excited state) cause selective light absorption.
It is suitable for windows or exterior walls of buildings in tropical areas that require both lighting and heat insulation. Many of the high-end and stylish high-rise buildings in Lagos and Apapa, the capital and most important commercial port of Nigeria, use it do make a variety of urban decorations, and each building has achieved energy-saving and cool indoor environment.
However, in the temperate and frigid urban residential complexes, sunshine is necessary to be able to sterilize, disinfect and deodorize. China green glass suppliers believe that if the sunshine has a loss by half, it is not worthwhile.
Tsol, the abbreviation for solar direct Transmittance ratio, is very important to China manufacturers and determines green glass price. In the solar spectrum (300nm to 2500nm), the ratio of solar energy intensity to incident solar energy directly through the glass. It includes the degree of transmission of ultraviolet, visible, and near-infrared energy, but does not include the energy portion of the glass that absorbs energy from direct sunlight and transmits it twice to the outside.
