Blue tungsten oxide powder may be applied for manufacturing ceramic microsphere. And usage of obtained heat insulation ceramic nano particles is as follows: The first step: According to the requirements of visible light index and infrared shielding index, add appropriate weight of heat insulation masterbatch by calculated amount; The second step: Uniformly mix the heat-insulating masterbatch with ordinary plastic particles; The third step: produce the transparent heat insulation film in accordance with the biaxial stretching process, or produce the transparent…
