Dark blue nano tungsten oxide for preparing near infrared shielding material is a new type of nano heat insulation material, which can shield most of IR and UV rays, especially for the near-infrared region with a wavelength of 800-1000nm and the ultraviolet region below 380nm. And the absorption and reflection effect is obvious.
Such near-infrared absorbing material has a purity of more than 99.99% and a particle diameter of 50-100nm. It is prepared by high-temperature calcination. The tungsten oxide is a nano grain size tungsten oxide particle with a dark blue appearance, hence the name - dark blue nano tungsten oxide. This new heat insulation material has excellent thermal insulation and UV resistance. And it is no wonder that blue tungsten oxide can be used as a near-infrared shielding material. The application of this new heat insulating material is expected to be widely promoted in the future. So, this scene has emerged: you can see it where are equipped with windows in the future - heat insulating glass.
