Nano grain size yellow tungsten oxide is a infrared ultraviolet shielding material, which means that it may shield infrared rays and ultraviolet rays in sunlight. Thus, it may be applied to architectural glass to effectively block the infrared radiation of sunlight through transparent glass, allowing 80% of visible light to enter the room through the glass. And it may block the ultraviolet radiation of about 99.9% to achieve the effect of “coolness in summer”. It is energy-saving and environmentally friendly,…
