Violet tungsten oxide is an excellent thermal insulation coating, which may be used in the fields of architectural glass and automotive glass in the form of thermal insulation film. This type of heat insulating coating has high heat insulation, which can effectively block solar energy. The coating also has high ultraviolet blocking rate, which can prevent indoor objects from fading and aging and protect human body from ultraviolet rays. Besides, the coating has high light transmittance so that it does not affect the optical properties of the glass. in other words, it does not influence the day lighting.
The thermal insulation film of nano grain size violet tungsten oxide has good infrared blocking rate, which is not less than 95%. The infrared reflection rate is not less than 20%, the visible light transmittance is between 70% and 90%, and the ultraviolet transmittance is about 99%. At present, the construction methods of glass heat-insulating coatings include spray coating, spray gun spraying, sponge coating, and roller coating. Among them, the sponge roller coating method is the most commonly used, as its application is not limited to the construction environment. And the method is easy to operate. Also, it saves material and labor. Besides, the construction area is large.
