WO3 Nanopowder Applied for Building Glass Thermal Insulation Coating

WO3 nanopowder may be applied to manufacture a transparent building glass thermal insulation coating. When such coating is applied to building glass window or glass door, it seems that they are putting on "heat preservation jacket" or "heat insulation film".

According to reports, the coating is composed of nano-scale semiconductor material - tungsten oxide. In the summer, the semiconductor material is oscillated by free electrons to block the infrared rays in the sunlight from entering the room through the window. In winter, it can block the indoor infrared rays from being emitted, and the effect of “warm in winter and cool in summer” is achieved. The semiconductor material is made of nano-scale, which enables the paint to "release" most of the visible light in the sunlight, keeping the window glass transparent. In addition, transparent heat insulation coating of nano tungsten oxide can block some of the ultraviolet rays and reduce the damage of UV to human skin, indoor furniture and accessories. Compared with some imported heat-insulating films, tungsten oxide nano heat-insulating coating has a higher shielding rate to solar energy at the same light transmittance. And the effect of controlling indoor temperature of such coating is more obvious, reducing the utilization rate of air-conditioning and heating equipment, to achieve the purpose of energy conservation and consumption reduction.
