Hyamine is a strong complexting agent, it has different complexting ability for tungsten and molybdenum. Using this difference can realize tungsten and molybdenum separation.
Nano grain size tungsten trioxide for thermal insulation film may be prepared by many different preparation methods. What are their advantages and disadvantages? Tungsten trioxide with special morphology can be prepared using different preparation methods such as hydrothermal synthesis method, precipitation method, sol-gel method, microemulsion method, gas-liquid reaction method and template method. The advantages and disadvantages of these preparation methods are as follows: The WO3 powder prepared by hydrothermal synthesis method has the advantages of complete grain development, small particle…
Nano grain size tungsten trioxide may be applied for manufacturing thermal insulation paper due to its thermal insulation performance. This kind of paper is excellent for use as die cut gaskets and seals as it resist high temperature, acid, alkali and other corrosive substances. And it is available in a variety of widths and thickness for your specific application. Tungsten trioxide also has wetting property. For example, the superhydrophobic coating with photochromism and mechanical stability can be prepared using tungsten…
Yellow tungsten oxide nanopowder can not only be applied for producing ceramic microsphere with high dispersity and excellent dyeing effect, but also be used as a type of special wettability material for emulsion separation in water pollution control. It is an important inorganic material that can be applied in the treatment of oil waste water. For example, yellow tungsten oxide film composed of a plurality of micron square prisms and microspheres may be prepared on a 2300 mesh stainless steel…
Yellow tungsten oxide nanopowder may be used to manufacture nano-ceramic color master. While by combing yellow tungsten oxide and its surface wettability, the application will be wider. For example, it can be applied in water pollution control. For example, a series of yellow tungsten oxide materials with special surface wettability can be synthesized by different methods and be applied in the fields of emulsion separation and superhydrophobic coating. By changing the pH value of the precursor in the hydrothermal process,…
Yellow tungsten oxide nanopowder may be used to produce nano-ceramic dispersion solution, which has excellent dispersibility. And this property is inseparable from its superhydrophobic property. What superhydrophobic yellow tungsten oxide particle means? Due to the hydrophilicity of yellow tungsten oxide, water droplets dripping on the surface of the yellow tungsten oxide particles can rapidly penetrate into the sample. Under the combined action of the coarse structure of yellow tungsten oxide and octadecyltrichlorosilane, the modified yellow tungsten oxide particles exhibit excellent…
Yellow tungsten oxide nanopowder is a type of near-infrared shielding material, which is mainly applied in different fields where require high heat insulation performance in the form of heat insulating film or coating. In addition, yellow tungsten oxide can also provide a new solution to solve oil pollution problem. Underwater superoleophobic yellow tungsten oxide films have been fabricated on 2300 meshes stainless steels via the modified hydrothermal process. SEM was used to analyze the surface morphology and results showed that…
Yellow tungsten oxide nanopowder may be applied for producing heat insulating window glass in the form of heat insulating thin film. However, why do you need to choose a window film with higher heat insulation performance? It is mainly for improving human comfort and traffic safety. It is known that people who are driving at high temperature can easily feel fatigue, and therefore cause lack of concentration, and even lead to “road rage”. While the high heat insulation window glass…
There are several methods include extraction method, precipitation method and ion exchange method to realize the separation. Activated carbon adsorption method is a special method.
Yellow tungsten oxide nanopowder may be used for the preparation of window heat insulation film, which is mainly applied in buildings and automobiles with high thermal insulation performance. And it can also play a significant role in privacy protection and beauty. Those outdoors cannot see the indoor scene, while the view is clear and natural if you look out from the room. Certainly, you should take the self-cleaning properties of building glass into account. In other words, the self-cleaning properties…
