Infrared Thermal Insulation Nano Material: Cesium Tungsten Bronze Nanopowder

Cesium tungsten bronze nanopowder is a kind of infrared thermal insulation nano material, which can be applied in the form of transparent heat-insulating film for building energy efficiency.

Energy on the earth comes from the sun’s radiation. Electromagnetic waves are the form of energy delivered by the sun. The “Energy Distribution of the Solar Spectrum” is shown in the figure below.energy distribution of the solar spectrum picture
As can be seen from the figure, in the total solar radiation energy, the ultraviolet with wavelength in the range of 200~380nm accounts for about 5%; the visible wavelength in the range of 380~780nm accounts for about 43%; and the near-infrared wavelength range of 780~2500nm accounts for about 52%. As you may have known, 98% of the total solar radiation energy is concentrated in the wavelength range from 200nm to 2500nm. However, among them, only visible light is useful for building lighting. Other wavelengths of sunlight can cause energy consumption in some buildings. The energy lost through doors and windows occupies a very large proportion of the overall energy loss of building. Therefore, building glass energy-saving technology came into being to reduce building energy consumption. Subsequently, the cesium tungsten bronze transparent heat insulation film also comes into people's view.infrared thermal insulation nano material cesium tungsten bronze nanopowder picture
