Tungsten trioxide is a semiconductor material with special optical properties, so it is often used to prepare new heat insulation materials such as kitchen thermal insulating film. With the applications of tungsten oxide nano materials in the field of thermal insulation, more and more experts and scholars have noticed it. They started to focus on tungsten oxide, for example, how to prepare tungsten oxide? The following is a method for preparing tungsten trioxide by treating seed sodium tungstate solution.

Tungsten trioxide has promising applications in the fields of balcony thermal insulating film. And such a heat insulation film can be a functional transparent PVB film material, which is obtained by blending nano tungsten oxide material with PVB. This is a new type of heat insulation film, which solves the difficulty of large haze of functionalized PVB transparent film material, with the characteristics of environmental protection.

Tungsten trioxide for preparing bedroom thermal insulating film is not pure tungsten trioxide powder, but doped tungsten trioxide nano powder. And the prepared heat insulation film is a new type of energy-saving material, which is environmentally friendly with long service life.

Tungsten trioxide is a functional material that can absorb light of a specific wavelength - mainly near-infrared light (heat radiation in the sunlight), so it can be used to produce living room thermal insulating film. With its popularization and application in the field of heat insulation, the preparation of tungsten trioxide powder has attracted much attention from the scholars. And the following is a method for preparing ultrafine tungsten trioxide.

Tungsten trioxide can be made into tungsten trioxide nano slurry first, and then used together with other components to produce bathroom thermal insulating film. Some experts have prepared a high-performance PVB thermal insulation film, whose composition and mass percentage are: tungsten trioxide nano slurry of 0.1‑0.5%, wherein tungsten trioxide particle diameter in the slurry is less than 20nm; PVB resin powder of 50‑50.80%; plasticizer of 18‑45%; antioxidant of 0.1‑1%; UV absorber of 0.05‑1%.

Tungsten trioxide is often doped with cesium element for producing glass dome thermal insulating glass coating, which is a new type of solar-radiation-shielding material, that is, a new heat-shielding material. Such transparent heat insulation coating reduces the solar radiation while holding the visible light transmittance.

Tungsten trioxide, doped with cesium metal, is a good functional material for producing office thermal insulating glass coating --- a new type of transparent smart material with high heat insulation and high preservation effects. But why such a heat insulation material is required in many places? The building energy consumption in developed countries such as Europe and the United States accounts for about 1/3 of the total energy consumption in the country, and China also accounts for more than 25%.

Tungsten trioxide for producing exhibition hall thermal insulating glass coating is nano particle size tungsten trioxide. And the prepared transparent heat insulation coating is a new type of anti-infrared coating, which can turn ordinary glass into energy-saving glass.

Tungsten trioxide, doped with alkali metals, is increasingly applied for preparing hotel thermal insulating glass coating. Therefore, the preparation of the raw material tungsten trioxide powder is achieving more attention. In this regard, the experts introduced a method for preparing tungsten trioxide. The specific steps are as follows:

Tungsten trioxide for preparing sun room thermal insulating glass coating is tungsten trioxide nano powder. According to the experts, the tungsten trioxide nanoparticles are often doped with alkali metals to obtain tungsten bronze nanoparticles such as CsxWO3 nanoparticles. And nano particle size CsxWO3 is actually the one that is used to produce sun room thermal insulating glass coating due to its good optical properties.
