Ultra-white glass is not necessarily better the more transparent it is. Although high light transmittance is an important characteristic of ultra-white glass, evaluating its quality requires consideration of multiple aspects.
First, the reason why ultra-white glass has high light transmittance is that the iron content in its raw materials is extremely low, far lower than that of ordinary glass. This ensures that ultra-white glass absorbs less of the green and purplish-red bands in visible light, making the glass color more consistent, with light transmittance reaching over 91.5%, or even higher. However, light transmittance is not the only standard for evaluating the quality of ultra-white glass.
Secondly, ultra-white glass also has the following advantages:
Low self-explosion rate: Due to the lower content of impurities such as NiS in the raw materials of ultra-white glass and the precise control during the melting process, it has a more uniform composition and fewer internal impurities compared to ordinary glass, thus reducing the probability of self-explosion after tempering.
Low ultraviolet transmittance: Although the ultraviolet transmittance of ultra-white glass is relatively higher than that of ordinary glass (but not all ultra-white glass has this characteristic, and it can usually be improved through coating and other technical means), in some application scenarios, such as museums, ultra-white glass can still effectively reduce ultraviolet transmission, slowing down the fading and aging of various exhibits in display cases.
Good processing performance: Ultra-white glass has all the processable properties of high-quality float glass and can undergo various deep processing like other float glass, such as tempering, bending, lamination, and insulating glass unit assembly.
In addition, ultra-white glass also has some limitations, such as relatively high solar energy transmission, which may lead to faster indoor and outdoor temperature difference convection. This may not be the best choice in some climatic conditions (such as high-heat areas in southern cities).
