Nano tungsten trioxide for the production of exhibition hall thermal insulating glass coating is a well-known dingal material with spectral selectivity. More specifically, such a heat insulation coating can shield most of the infrared and ultraviolet rays, and allow the visible light to pass through.

It is reported that the range of radiation wave reaching the ground from the sun is about 200nm-2500nm, of which 200nm-400nm is ultraviolet, 400nm-800nm is visible light, 800nm-2500nm is near infrared. Wherein, near infrared can be divided into short wave near infrared (800nm-1100nm) and long-wave near infrared (1100nm-2500nm). And the infrared is the culprit that causes heat radiation. So how to do to save energy? It is necessary to shield infrared and ultraviolet rays as much as possible, and the transmittance of visible light must be high. The exhibition hall thermal insulating glass coating of nano tungsten trioxide is just such a transparent thermal insulation coating.
