Nano particle size cesium tungsten oxide may be applied for preparing thermal insulation masterbatch. The masterbatch can be prepared by a grinding dispersion and a wet granulation process with the effect of absorbing near-infrared radiation. In addition, such masterbatch can effectively block UV rays. The experiment proves that the color masterbatch may be used to prepare thermal insulation film, and thus be applied to the architectural glass, which can reduce the electricity cost by 30%, and achieve the results of energy conservation, emission reduction and high functionality.

Nano particle size cesium tungsten oxide may be used to prepare near infrared shielding material. Wherein, the raw material is cesium tungsten bronze nanoparticles, and the obtained material may be a heat insulating film, a heat insulating dispersion liquid, a heat insulating coating or the like. They can all be applied for the heat insulation of architectural glass. Nowadays, transparent insulation materials of cesium tungsten bronze nano particles are more and more widely used in the construction field. Therefore, the preparation of the cesium tungsten bronze nano powder is becoming more and more important.

Nano particle size cesium tungsten oxide, or nano particle size cesium tungsten bronze, may be used for preparing a functional color masterbatch --- nano-ceramic color master, which is a new type of heat insulation color masterbatch. The obtained color masterbatch has heat insulation effect and heat preservation effect so that it may be used for producing heat insulating materials such as heat insulation film, and thus be applied for heat insulation of architectural glass such as a sun room. The raw material cesium tungsten bronze powder used is nanopowder. So, what is nanopowder?

Nano particle size cesium tungsten oxide, or cesium tungsten bronze nanoparticles, may be used for preparing infrared thermal insulation nano material such as transparent thermal insulation coating, and thus be applied to architectural glass to provide thermal insulation performance without affecting lighting. Experts said that the thermal insulation test of such thermal insulation coating glass can be achieved by the following method.
