Tungsten oxide may be used in the manufacturing of near-infrared shielding material, i.e., thermal insulation material. And this kind of thermal insulation material can be made into nano thermal insulation film with excellent physical properties such as waterproofing, weather resistance, aging resistance, and no communication interference. Also, it has high infrared shielding effect, high ultraviolet shielding performance, high visible light transmission and other optical properties. Besides, compared with other heat insulating film, it is safer and more durable with higher…

Tungsten oxide can be applied for the production of heat insulating window glass to make it shield near-infrared rays. Nano grain size tungsten oxide plays a role of heat insulation film on window glass. Infrared absorption technology is applied to heat insulation film to meet people’s pursuit of more comfortable driving space by reducing sun’s damage to drivers and passengers. It blocks the scorching heat in summer with the most simple and elegant design. So, why not adopt this kind…

Tungsten oxide can be applied for manufacturing thermal insulation coating. Since the IR radiation into heat will be surprisingly in high efficiency, and this tungsten oxide material may be applied at very low concentrations, the color itself may be acceptable in most applications. Preparation of Tungsten Oxide/ Solvent type Polyurethane Composite Film 1. 10g of WO3 powder, 90g of MEK and 150g of zirconium balls were ball milled. After milling for a period of time, a WO3/MEK suspension was obtained…

Tungsten oxide is a type of NIR-shielding material with high transparency although it is slight blue in color, which can be applied for the production of thermal insulation film. Study on Tungsten Oxide/ Solvent type Polyurethane Composite Film The composite heat insulation film can be prepared by using tungsten oxide (WO3) powder and solvent type polyurethane (PU) as raw material. After the dispersed WO3 suspension and the PU were degassed and stirred, the composite film was formed by using a…

Tungsten oxide (WO3) may be applied for producing thermal insulation paper. Tungsten oxide is a new material discovered in recent years, which can be used as transparent heat insulation coating. WO3 nanopowder has the best near infrared absorptive capacity. It not only has strong absorption characteristics in the near-infrared region, and has strong transmission characteristics in the visible region, but also in the ultraviolet region it has a strong shielding property. It also has broad application prospects in the field…

Cesium tungsten bronze can be applied for producing ceramic microsphere. Recently, many kinds of ceramic particles have been attracted very much interest for UV-visible and near-infrared (NIR) region cut-off behavior. Particularly, tin-doped indium oxide and antimony-doped tin oxide have been widely used as materials to perform purpose of NIR-shielding effect. At this point, electrochromic device containing cesium tungsten bronze also has been examined for smart film applications with changeable modulations in optical spectra. It has been reported that cesium tungsten…

Cesium tungsten bronze can be applied to produce nano-ceramic color master as nano grain size cesium tungsten bronze powder has highlighted the near-infrared absorption and visible light transmission characteristics. And therefore, this kind of nano-ceramic color master has excellent transparency, and can isolate the infrared in sunlight so that it can be applied in window glass of building or automobile glass to achieve infrared-isolation. Energy and environment become the two major social problems with the rapid development of social production…

Cesium tungsten bronze can be applied for the manufacturing of nano-ceramic dispersion solution. And this kind of dispersion solution has very excellent transparency and IR cut dings so that it can be applied to the lamination of highly IR cut film, such as heat insulating window glass. Pre-disperse 67~80% of solvent, 10~30% of nano cesium tungsten bronze powder and 2~10% of dispersing agent by weight percent in a smashing effect of stirring or ultrasonic wave. Then, perform grinding dispersion to…

Cesium tungsten bronze is a new near-infrared shielding material with selectivity and strong near-infrared absorption in the range of 800nm~1200nm. The near-infrared shielding material coated with cesium tungsten bronze has superior solar control effect. It diminishes near-infrared rays of shorter wavelength which has much of the heat energy in sunlight compared to ITO (tin-doped indium oxide) and ATO (antimony-doped tin oxide). Cesium tungsten bronze can be surface-coated on glass or PET film, or mixed into the plastic material such as…

Tungsten oxide has the advantages of high transparency, high thermal insulation, and NIR-shielding performance so that it can be applied for window heat insulation film. Why window heat insulation film is necessary for building windows? 60% of the solar thermal energy enters the room through the window, while the general glass can only block 7% of the solar thermal energy, which makes the indoor temperature in the summer high within a certain temperature range, resulting in the frequent and lasting…
