Nanometer yellow tungsten oxide can effectively shield the energy in the near-infrared and far-infrared regions with excellent thermal insulation properties. Nano grain size yellow tungsten oxide also has the characteristics of good transmittance, weather resistance and stability. Moreover, such nano dispersion of heat insulation performance is still very transparent at high solids (to 50wt%). Therefore, yellow tungsten oxide nanopowder can be used for the preparation of thermal insulation dispersion.
The heat insulating dispersion of yellow tungsten oxide can reduce the infrared energy from the sun or other sources to keep the indoor temperature lower in the summer, and can also control the heat loss in the winter, thereby reducing the application of air conditioning to achieve energy saving effect. In addition, the heat-insulating film made of nano yellow tungsten oxide does not have a halo effect. Also, it does not interfere with the user's vision and judgment in a dark environment. In addition, it also has a good effect on the automobile film.
