Yellow tungsten oxide nanopowder may be applied to a new energy efficient glass such as energy-saving glass curtain wall, which is environmentally friendly of great importance in building renovation. Some experts have conducted experiments on the heat insulation effect of common insulating glass and tungsten oxide smart glass. The test results show that:

Yellow tungsten oxide nanopowder may be applied to energy-efficient glass in the form of a smart film. In the future, there will be more environmentally friendly smart film products coming into our lives. For example, the glass used in the energy-saving glass curtain wall is a smart glass or an electrochromic glass of tungsten oxide nanoparticles for building. It can change color according to temperature changes due to a layer of smart nano-film on the glass.

Nano WO3 may be used to produce a new energy efficient glass. As we all know, at present, doors and windows, which are affecting building energy consumption, are generally thin-walled lightweight components. And doors and windows are weak links in building heat preservation, heat insulation and sound insulation. Especially doors and windows can lead to energy loss of buildings through radiation transmission, convection transmission, conduction transmission and air penetration. The energy loss of ordinary single-layer glass windows accounts for about 50% of the energy consumption of building heat preservation in winter and heat insulation in summer.

Nano WO3 may be used to prepare an energy-efficient glass. This new type of glass shields near-infrared and ultraviolet light with good thermal insulation effect, which is consistent with the structural adjustment target of domestic energy-saving glass. So, what is the structural adjustment goal of China's energy-saving glass industry?

Tungsten oxide is one of the important raw materials for the production of a new energy efficient glass. Nowadays, with the economic development mode and the demand structure upgrade, the demand for traditional glass products will remain basically stable or slightly declining, and the demand for energy-saving glass continues to grow.

Tungsten oxide may be applied to an environmentally friendly and energy-efficient glass. As we all know, in the face of the overcapacity of the glass industry, enterprises should firmly grasp the background of “the environment force green production”, and resolutely do not do backward production capacity. Instead, by increasing technological innovation, a production line with advanced technology and equipment will be built in the country. In short, it is based on energy conservation, to seize the opportunity, and occupy the high-end glass supply market.

Tungsten oxide may be used to produce a transparent thermal insulation film and thus be applied to architectural glass to obtain a new type of energy efficient glass. As you may know, at present, smart film of heat insulating performance sold on the market mainly rely on current changes to change the state of the film. Most of the smart films require manual adjustment and consume electricity. While the smart film of tungsten oxide heat insulating nano particles is a photochromic film, which will not consume electricity. And such film can play its role without manual adjustment.

Tungsten oxide has electrochromic property so that it may be used to prepare a high-performance energy-saving glass. And therefore it is often applied in architectural glass doors, windows or glass curtain walls. According to experts, unlike ordinary glass, such glass can automatically adjust the transparency of the glass in accordance with the change of temperature, effectively shielding ultraviolet rays and infrared rays, and thereby saving energy consumption by about 10%.

Yellow tungsten oxide may be used in the glass deep processing industry, that is, to obtain a new energy efficient glass. For example, it may be applied in super energy-saving insulating glass. This is a new type of insulating glass, which replaces the aluminum strip with special rubber strip to reduce the heat transfer efficiency of the windows. With seamless connection, it will never fog. Also, it has tight sealing. Moreover, the tungsten oxide heat insulation nanoparticles may greatly improve the performance of the insulating glass, and provide technical guarantee for high-performance hollow windows.

Yellow tungsten oxide may be used to produce a transparent energy-saving coating, that is, a transparent thermal insulation coating, which is applied to the renovation of existing architectural glass to obtain an environmentally-friendly energy-efficient glass. This new type of glass can make the surface of the building glass door, glass window and glass curtain wall have self-cleaning, anti-scaling and anti-static functions. Also, such glass does not need to be cleaned at regular intervals. It can be kept clean and beautiful by rain washing.
