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…

Nano grain size tungsten trioxide may be used to produce nano-ceramic color master, which has the characteristics of high temperature resistance, high toughness and good brightness. It also has excellent dispersibility and thermal stability during melting and blending process. In addition, it makes the product have the highest mechanical strength retention rate. The ceramic color master has an appearance of bright yellow masterbatch with a solid content of 9.0%, a transmittance of 70-85%, an infrared blocking ratio of 80-95%, and…

Nano grain size tungsten trioxide may be used to prepare nano-ceramic dispersion solution so that the dispersion solution may have the advantages of high heat insulation, high solid content and low viscosity. And it can also reduce the use of the solvent as much as possible. Generally, the dispersion solution should be used in combination with various solvents, resins and auxiliaries. What should be noted is that the compatibility of those materials should be confirmed before use. Electrochromic property is…

Nano grain size tungsten trioxide may be used for the preparation of near-infrared shielding material, which mainly reflects its photochromic property. While tungsten trioxide also has electrochromic property. For example, a uniform and dense nano-Ag film may be prepared by vacuum coating, and then a layer of tungsten trioxide may be deposited thereon by electrochemical method to prepare a nano-Ag/WO3 composite film. The ultraviolet-visible absorption spectrum of the composite film when different voltages are applied in the electrolyte solution shows…

Nano grain size tungsten trioxide may have an application in heat insulating window glass, which make the glass have the following characteristics: 1. High heat insulation: the shielding rate of infrared rays is from 60% to 99%, which varies with the addition ratio of WO3. 2. High light transmittance: visible light transmittance is at the range of70-80%. According to the industry standard (GB/T 31849-2015), the light transmittance of front window of automotives is higher than 70%. 3. Weather resistance: color…

Nano grain size tungsten trioxide may be applied for window heat insulation film with electrochromic property. Electrochromism refers to the phenomenon that the color or transmittance of a material changes reversibly under the action of a certain electric field or voltage. This type of heat-insulating glass not only has the ding of beautifying the building, but also reduces the indoor temperature, thereby reducing the use of air conditioners in hot summer and the occurrence of air conditioning diseases. In addition,…

Nano grain size tungsten trioxide for heat insulation masterbatch has photochromic property so that it may be applied to thermal insulation coatings or thermal insulation films. And finally it may be applied to architectural glass such as glass curtain wall, glass window, glass door, glass skylight, and glass sun room, etc. Also, it may be applied in many other places where high heat insulation and high transparency are required. It not only improves the comfort of human body, but also…

Nano grain size tungsten trioxide may be used in thermal insulating glass. And nano tungsten trioxide with good dispersibility may be prepared by hydrothermal synthesis method using sodium tungstate as a tungsten source and formaldehyde as an organic inducer. In this process, the pH value is adjusted with hydrochloric acid (HCl). Under the irradiation of 3W UV lamp, the color difference of formaldehyde-induced tungsten trioxide nanopowder was 20, while the color difference of tungsten trioxide powder without formaldehyde inducer was…
