Tungsten oxide nanoparticles are important raw materials for manufacturing glass curtain wall heat insulation coating. Specifically, the nano particle size tungsten oxide is first prepared into heat insulation nano dispersion, and then mixed with a resin to uniformly produce a smart heat-insulating coating. So, the energy saving coating can automatically adjust the heat (IR) transmission according to the change of the ambient temperature, and therefore maximize the optimization of heat distribution to achieve the purpose of “warm winter and cool…

The glass curtain wall heat insulation coating of tungsten trioxide nanoparticles can shield the ultraviolet rays in the range of 320nm-460nm. It simultaneously allows the visible light of 440nm-780nm to pass through. In other words, such energy-saving coating does not affect the see-through and lighting effects. More details, please visit: http://www.tungsten-powder.com/tungsten-oxide.html As common glass does not have the ding of shielding heat radiation and ultraviolet light, it needs to be sprayed with a transparent heat-insulating coating to form a heat-insulating…

WO3 nanoparticles can be used to prepare a heat insulating nano dispersion. Applying this dispersion to the building glass, and a coating layer (film) formed on the surface of glass, thereby transforming the common transparent glass into a transparent heat insulation glass. Under the illumination of sunlight, the color of the film changes darker or lighter with the intensity of the light, so the light intensity is automatically adjusted and always maintained at an appropriate level.
