Nano grain size yellow tungsten oxide is an excellent near-infrared shielding material (heat insulation material or thermal insulation material) that may be applied to building glass, and more specifically, on energy efficient glass. According to relevant experts, about 70% of the energy loss of the entire building is consumed on doors and windows. Therefore, the most important thing in building energy conservation today is the development and application of energy efficient glass, which means that the application prospect of heat…

Nano grain size yellow tungsten oxide has photochromic property so that it may be used in heat insulating window glass to shield heat and beautify your car. Also, it is anti-explosion and anti-glare with long working life. Why it can shield heat? As the heat is mainly produced by near infrared rays and ultraviolet rays in sunlight, and yellow tungsten oxide block these rays. And why it can beautify your car? As the yellow tungsten oxide film shows up dark…

Nano grain size yellow tungsten oxide may be applied for preparing window heat insulation film, and thus be used in glass window of building, which is also called “smart window”. It plays a role of heat insulation and energy saving. Also, it improves human comfort and saves energy charge of air conditioning in hot summer. There are two methods for applying yellow tungsten oxide in heat-insulating glass, which is mainly in accordance with its discoloration properties, that is, by electrochromic…

Nano grain size yellow tungsten oxide may be applied for preparing heat insulation masterbatch, and therefore be applied to exterior wall of building, skylight, sun room, greenhouse, industrial lighting belt and the like. The heat insulation rate and light transmittance rate of this type of masterbatch may be different by adjusting the addition amounts of yellow tungsten oxide. And the proportion will be added according to actual demand. The kind of heat insulation particles can greatly reduce materials used in…

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…
