Ion exchange method principle is sulfurizing sodium tungstate solution containing molybdenum or ammonium tungstate, molybdenum is absorbed on the resin, after tungsten entering exchange solution to realize tungsten and molybdenum separation.
Nanometer blue tungsten oxide may be applied for preparing thermal insulation film so that such thin film will have the properties of high transparency (visible light transmittance higher than 70%), high heat insulation effect, one-way see-through, privacy, anti-glare, and anti-UV (UV blocking rate is up to 99%). Also, the heat-insulating film is explosion-proof and environmentally friendly. With such a thermal-insulation film, there is no need to pull the curtains. And you can enjoy the beautiful scenery outside the window more…
Nanometer blue tungsten oxide for ceramic microsphere may be produced stably by adjusting other process parameters without inletting H2 or NH3. Then, observe the effect of reduction time on blue tungsten oxide. And it is found that: The effect of reduction time on blue tungsten oxide is as follows: With the extension of reduction time, the oxygen index (O/W) shows a downward trend, and residual ammonia also shows a downward trend. But the effect of test temperature is much greater…
Nanometer blue tungsten oxide for thermal insulation masterbatch can be prepared by a self-reduction process of ammonium paratungstate. In other words, by adjusting other process parameters without inletting hydrogen or NH3, the blue tungsten oxide can be prepared stably. Observing the effect of temperature on blue tungsten oxide, it was found that: With the increase of temperature, the particle size of blue tungsten oxide changed irregularly. But, the change was small. It proved that the temperature condition was not significant…
Nanometer blue tungsten oxide may be used to prepare nano-ceramic color master, and therefore be applied to produce heat insulation products such as heat insulation film or heat insulation plate. And the prepared film or plate has the performance of high transparency, high heat insulation, energy conservation, environmental protection, safety, beauty and privacy. Such heat insulation material is a type of high-tech product. If the heat insulation film is prepared by using blue tungsten oxide as raw material, it will…

And the obtained dispersion solution has a lot of excellent properties such as super-dispersibility, high heat insulation and high transparency. Blue tungsten oxide can also be used to prepare tungsten powder. As you may have known, tungsten processing materials include cemented carbide, tungsten alloy, tungsten wire, tungsten electrode, and so on. Since the performance and production scale of these materials have reached or are close to the world…
Nanometer blue tungsten oxide may be applied for producing thermal insulation dispersion. The prepared dispersion can be widely used in various automotive films, architectural films, architectural coatings, plastics and resin products as it has good compatibility with various resins, coatings and plastics. And they can be mixed at will. Such dispersion has high transparency and high heat insulation effect. More specifically, the dispersion can shield most of the infrared light at 950nm, which is more than 90%. The dispersion can…
Nanometer blue tungsten oxide may be applied for preparing thermal insulation dispersion liquid. The obtained dispersion liquid has the characteristics of uniform particle size and high crystallinity. Such dispersion liquid also has super-dispersion property, so that it is easily dispersed in various polar or non-polar organic solvents and water. And therefore it is used for applications such as heat insulating glass. Blue tungsten oxide can also be used to prepare tungsten powder. There are many factors affecting the performance of…
Nanometer blue tungsten oxide may be applied for producing near infrared shielding material, such as thermal insulation films. The obtained heat-insulating film has an ultraviolet blocking rate of 99% and a visible light transmittance of more than 70%. Moreover, the heat insulation film also has an explosion-proof effect, which can resist a certain impact force and prevent the glass from breaking and scattering. Blue tungsten oxide can be prepared by self-reduction of ammonium paratungstate. Under special process and technical conditions,…
