Ammonium metatungstate may be applied for producing thermal insulation film.
Ammonium metatungstate enables this kind of dingal film to block near-infrared rays. And its infrared shielding rate is as high as more than 90%. Moreover, this film has good visible light transmittance, which is higher than 80%. Therefore, it can save energy consumption by 20-30% when used in building glass. What’s more, from the point of view of application, this kind of dingal film has weather resistance, anti-aging, and long service life.
Thermal Insulation Film Applied for Architectural Glass
In summer, the film may absorb most of the infrared energy in sunlight and radiate to the outside of the window. Due to the large air flow on the outside, 80% of the heat of the substrate surface is taken away quickly, and the amount of heat radiated to the inside is reduced, so that it plays a role of heat insulation. Besides, the air-conditioned air will not leak out. And therefore, the energy consumption of air-conditioning may be reduced.
