Tungsten oxide may be applied for the manufacture of nano-ceramic color master. And the color master can be used to prepare nano-ceramic dingal film with high thermal insulation. There are black thermal insulation film, blue thermal insulation film and other thermal insulation film with different colors and high light transmittance. Among them, the two kinds of thermal insulation films, black and blue, UV blocking rate of up to 98%. While the IR blocking rate is slightly different from each other.…
