Why not choose nano blue tungsten oxide as the transparent thermal insulation material you needed? Blue tungsten oxide may make this kind of dingal heat insulation material have the advantages of high heat insulation and high transmittance of visible light, so that it may be used to prepare heat insulation film of building and automobile. And therefore, it makes human body feel more comfortable. And it also saves energy. Most of blue tungsten oxide is produced in a semi-closed electrical…

Blue tungsten oxide powder is a type of transparent thermal insulation material, which may be used to prepare transparent heat insulation film, so that it has excellent ultraviolet and near-infrared shielding characteristics and high visible light transmittance. Therefore, the observation of phase structure of blue tungsten oxide has certain guiding significance for blue tungsten oxide applying to the production of thermal insulation materials. Phase Structure of Blue Tungsten Oxide The composition of blue tungsten oxide is subject to the preparation…

Blue tungsten oxide (BTO) is one of many types of transparent thermal insulation material, which may be used to produce thermal insulation film and heat insulation paper. The BTO can be prepared by using APT as raw material and reducing under certain calcination conditions. APT was used as raw material, and was reduced to blue tungsten oxide under certain calcination conditions. It was found that the morphology of APT affected the morphology of blue tungsten oxide obtained by reduction. APT…

There are many types of transparent thermal insulation nanopowders. Among them, blue tungsten oxide nanopowder has good near-infrared and ultraviolet shielding characteristics and high visible light transmittance. So, the transparent thermal insulation nanopowder can be used for the preparation of transparent heat-insulating film. The particles of the raw material APT powder have relatively regular hexahedral characteristic. And the APT powder is coarse with rough surface and many cracks. It was found by observing the morphology of the blue tungsten oxide…

As a transparent thermal insulation nanopowder, nano blue tungsten oxide has many excellent characteristics, such as high temperature resistance, uniform particle, anti-aging, resistance to acid and alkali, etc., and thus can be used for producing transparent thermal insulation film, which is mainly applied in building glass and auto glass. Some ammonium paratungstate powders produced by different manufacturers and different processes were used as raw material to be reduced to blue tungsten oxide under the same conditions. Tests were conducted to…

As a type of transparent thermal insulation nanopowder, the ding of blue tungsten oxide powder is mainly manifested in the production of transparent heat-insulating film. And this type of thermal insulation film has high visible light transmittance and good ultraviolet and near-infrared shielding characteristics. And therefore, it has a wide application in thermal insulation material such as building thermal insulation glass (window, door, and curtain wall, etc.) and auto window film. Effect of APT on the Morphology of Blue Tungsten…

Blue tungsten oxide (BTO) is a kind of transparent thermal insulation nanopowder. “Transparent” is used because it is transparent when it is applied in the thermal insulation films. The thermal insulation characteristic of blue tungsten oxide is determined by its special structure, which makes it has photochromic properties. When blue tungsten oxide is prepared by reducing ammonium paratungstate (APT), the phase transformation of BTO is as follows: APT→WO3+ammonium tungsten bronze→WO2.90→WO2.72 The products in this phase transformation process are all blue…

Blue tungsten oxide nanopowder may be applied to produce ceramic microsphere, so that it has good dispersion and thermal insulation in the thermal insulation material, and therefore applied for manufacturing thermal insulation films in different places such as building glass and auto glass. Phase Change During Reduction of Blue Tungsten Oxide Below 350°C, the main phase composition of the reduced blue tungsten oxide is WO3 and ammonium tungsten bronze. If the temperature rises to 400°C, a new phase of WO2.90…

Nano blue tungsten oxide (BTO), as a type of raw material to prepare ceramic microsphere, has the characteristics of high temperature resistance, high visible light transmittance, high hardness, high thermal insulation, good photochromism, and uniform particle size. Thus, the obtained dingal ceramic particles inherit some of characteristics of BTO such as uniformity, dispersity, stability, good thermal insulation and transmittance of visible light. It was found that curves of XRD (X-ray diffraction) of blue tungsten oxide obtained by reducing different APT…

Blue tungsten oxide powder may be applied for manufacturing ceramic microsphere. And usage of obtained heat insulation ceramic nano particles is as follows: The first step: According to the requirements of visible light index and infrared shielding index, add appropriate weight of heat insulation masterbatch by calculated amount; The second step: Uniformly mix the heat-insulating masterbatch with ordinary plastic particles; The third step: produce the transparent heat insulation film in accordance with the biaxial stretching process, or produce the transparent…
