Yellow tungsten oxide nanopowder may be applied for thermal insulating glass with high UV shielding rate, which is as high as 99%. What the 99% UV shielding rate means? --- The effect of this type of heat-insulating glass with high UV shielding rate is N times better than that of the sunscreen. And it has the characteristics of environmental protection and safety. Also, it may easily eliminate the sun's damage to the skin. Yellow tungsten oxide is mainly applied to glass in the form of coating. And the UV irradiation experiment on the yellow tungsten oxide coating helps to better understand the heat insulation performance of yellow tungsten oxide.
By using the mercury lamp with a center wavelength of 365nm and a power of 20W as the central light source, the photochromic performance and anti-UV properties of superhydrophobic yellow tungsten oxide coating were tested for a period of time at room temperature. During irradiation, the distance between the sample and the light source is 15cm. During the experiment, the water contact angle of the surface of yellow tungsten oxide coating was measured every 6h. Subsequently, the yellow tungsten oxide coating irradiated with ultraviolet light was placed under visible light to facilitate observation and measurement of changes in the surface of sample.
