Blue tungsten oxide nanopowder has special photochromic characteristic so that it may be applied for the production of thermal insulation masterbatch. And therefore, it may be used to produce heat insulation film with excellent heat insulation characteristic and stability. The stability here means that the dingal masterbatch will not react with the product when it is exposed to heat, light or high temperature for a long time. Oxygen Index and Color Change of Blue Tungsten Oxide Desiccant method may be…

Nano blue tungsten oxide may be applied for producing thermal insulation masterbatch so that it will have good heat insulation and light fastness. The both characteristics are attributed to the photochromic phenomenon of blue tungsten oxide (related to its specific structure), which solves the problem of fading and brittleness of irradiated products as they are exposed to near infrared rays and ultraviolet rays in sunlight. Effect of H2 Flow and Calcing Time on Morphology of Blue Tungsten Oxide At certain…

Blue tungsten oxide powder may be applied for manufacturing thermal insulation masterbatch so that it has excellent dispersity. In other words, the masterbatch will be uniformly dispersed in the product. And there will be no debasement of quality. Effect of Calcing Temperature on Morphology of Blue Tungsten Oxide Ammonium paratungstate (APT) was used as raw material to prepare blue tungsten oxide by calcing under hydrogen atmosphere. Calcination is performed at a temperature range of 350~550°C. And the prepared blue tungsten…

Blue tungsten oxide (BTO) may be used to produce thermal insulation masterbatch, which mainly plays the role of dyeing and thermal insulation. Thus, this kind of dingal masterbatch will have excellent heat resistance to withstand high temperature of many products during production process, and keep it stable. Morphology Analysis of Blue Tungsten Oxide Ammonium paratungstate (APT) was charged into the boat and placed in the high temperature zone within the quartz glass tube. And BTO was prepared by controlling the…

Cesium tungsten bronze nanopowder is a kind of nanoparticle with outstanding near-infrared absorption and visible light transmittance characteristics so that it may be applied for producing thermal insulation masterbatch. And therefore, it is widely used in the field of transparent heat insulation films such as heat insulation film of building glass and thermal insulation film of automotive glass. Nano cesium tungsten bronze powder can be prepared by many methods such as chemical vapor transmission method, thermal plasma method, high-temperature solid-phase…

Nano grain size cesium tungsten bronze powder may be applied for producing thermal insulation masterbatch, which may be added into the heat-insulating film. And the obtained film has multidingality, which is used in window to effectively shield ultraviolet rays and near-infrared rays. Some studies have shown that this type of thermal insulation film can reduce electricity expenses and beat the target of energy-saving, emission reduction and high dingality. How to use the nano ceramic insulation masterbatch? Add 2 ~ 20%…

Nano Cs0.33WO3 may be applied for the manufacturing of a type of dingal masterbatch — thermal insulation masterbatch, which has excellent spectral selectivity and stability. It means that Cs0.33WO3 has good heat insulation effect, thereby reducing energy consumption. Nano Cs0.33WO3 powder can shield the near-infrared rays that carry heat in the light wave radiation, and the near-infrared shielding rate is more than 95% while guaranteeing that the transmittance of visible light reaches more than 80%. Functional masterbatch refers to the…

Cesium tungsten bronze may be applied for producing thermal insulation masterbatch — a kind of dingal masterbatch, which has the performance of shielding ultraviolet and near-infrared rays. It is also a kind of tungsten bronze material with excellent optical properties. When tungsten bronze is not doped with Cs+, the tungsten bronze is yellow in color. And when the amount of Cs+ is increased to a certain extent, the color of the cesium tungsten bronze will be changed into blue. It…

Nano Cs0.33WO3, or nano cesium tungsten bronze, is a type of near infrared shielding material. The photochromic property of CS0.33WO3 is derived from the fact that the small radius metal ions (Cs+) in the cesium tungsten bronze can enter and exit freely in the tunnel structure. Cesium tungsten bronze is also called Cs-doped tungsten bronze or Cs-doped tungsten oxide. And its doping method is reversible doping. When the doping amount of the metal ions (Cs+) is changed, cesium tungsten bronze…

Nano cesium tungsten bronze is a kind of near infrared shielding material. And the study of the selective transmittance mechanism of cesium tungsten bronze found: In cesium tungsten bronze, the valence state of tungsten is a mixture of hexavalent (W6+) and pentavalent (W5+), and charge carrier hopping between the two valence states are very likely to occur. When W5+ is oxidized to W6+, lattice vacancies will occur, and the electrons lost by tungsten will occupy vacancies and become color center.…
