WO3 may be applied to prepare ceramic microsphere, which is a kind of nano infrared heat insulation masterbatch. Such new masterbatch may be added in the processing of heat insulation film, and the obtained film has versatility. For example, such film is attached to the glass door and glass window of the building to effectively block ultraviolet rays and infrared rays. The experiment proves that the heat insulation film of nano WO3 can also reduce electricity costs by 30%, and…
