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 the building structure and save construction investment costs. Data show that greenhouses using this type of heat insulation material are 50% less expensive than that of ordinary glasshouses.
Yellow tungsten oxide with small particle size, good uniformity and high purity may be prepared by sol-gel method. And it is especially suitable for industrial production. However, this method also has its disadvantages. For example, it is difficult to control the sol-gel transition. The solvent is easily agglomerated after drying if the transition is not so well. And the synthesis cycle of the method is generally longer.
