Nano grain size yellow tungsten oxide may be applied in thermal insulating glass to provide high heat insulation (shielding ultraviolet and near infrared rays) and high light transmittance (visible light). Yellow tungsten oxide can be prepared by sol-gel method. A Method for Preparing Yellow Tungsten Oxide – Sol-gel Method A certain amount of sodium tungstate crystal powder was stirred and dissolved in deionized water, and the concentrated HCl was added dropwise to the solution, stirred while being added dropwise to…

Nano grain size tungsten trioxide is a new near infrared shielding material that may be used in building energy conservation, more directly, on energy efficient glass. Therefore, you can see it “hidden” in the glass curtain wall, skylight, glass window and glass door. The reason why I say it “hidden” in different places is that the application of tungsten trioxide in the field of heat insulation has not been popularized, and “whether the glass uses tungsten trioxide material as material…

Nano grain size tungsten trioxide is a kind of infrared ultraviolet shielding material that may be prepared by different methods, one of which is sol-gel method. What is sol-gel method? Sol-gel method is a commonly used method for preparing nano-semiconductor powder. General, the preparing process is the hydrolysis of inorganic salt or metal alkoxide, then polymerization and gelation, or adding organic acid to the obtained solution system as ligand, and the pH value of the solution system is adjusted with…

Nano grain size tungsten trioxide is a kind inorganic transparent thermal insulation material, which will become one of the main development directions of transparent thermal insulation film in the future. And at that time, a lot of glass windows will be coated with such thermal insulation films. In addition, it should be noted that tungsten trioxide has various discoloration properties, namely electrochromic property, photochromic property and gasochromic property. The discoloration properties of tungsten trioxide itself have made it own broad…

Nano grain size tungsten trioxide is a type of transparent thermal insulation nanopowder. It is said to be transparent, mainly to describe the state it exhibits when it is applied in the form of thermal insulation film. Thanks to its own photochromic performance, this type of thermal insulation material may shield UV and near infrared rays, which are the main reasons of “hot” in hot summer. The thermal insulation nanopowder may finally be applied in the thermal insulation glass of…

Nano grain size yellow tungsten oxide may be used as a raw material for producing heat insulation coating, which mainly reflects the selectivity of yellow tungsten oxide for the transmission of different spectrums of sunlight. The development and application of such heat-insulating coating on the surface of transparent glass such as ordinary glass and PMMA is expected to solve the technical problem, which has always limited the building glass having high transmittance and high heat insulation. Such thermal insulation coating…

Nano grain size yellow tungsten oxide may be used in the production of thermal insulation coating so that it may be applied in building glass or automotive glass. Such transparent heat-insulating coating is thin with high hardness and good toughness. Also, it has good adhesion to the glass substrate without hollow drum and joints. Besides, it has the characteristics of easy construction, long service life and high economic benefit. And therefore, there will be a potential market for yellow tungsten…

Nano grain size yellow tungsten oxide may be applied for producing thermal insulation film and therefore be used in automobiles or buildings. The heat-insulating film not only has the characteristics of high heat insulation when it is applied in cars, but also reduces the glare and beautifies your car. In a word, it makes you travel in comfort. And when such thin film is used in building glass, it has similar dings. Yellow tungsten oxide (WO3) also has gaschromic property,…

Nano grain size yellow tungsten oxide may be applied for manufacturing thermal insulation paper so that it has the advantages of heat insulation, light insulation, anti-UV, safety and privacy protection. You may know that the part of the solar energy isolated by the glass is the total amount of reflection plus the amount of energy that the glass absorbs and then dissipates outward. Gasochromic property is also an attracted property of yellow tungsten oxide. A relatively regular porous yellow tungsten…

Nano grain size tungsten trioxide may be applied for preparing ceramic microsphere to make it have the characteristics of high visible light transmittance, high heat insulation, energy saving and environmental protection. Thus, it may be used for producing various transparent thermal insulation films or thermal insulation PC sheets of different thicknesses. Such film or sheet may be used in building window glass, skylight, and so on, which will achieve the effect of heat insulation and heat preservation, and therefore greatly…
