Blue tungsten oxide powder is a new material that may be used to produce heat insulation agricultural film. And the transparent agricultural film is mainly for use in flower greenhouses. The thickness of such film is very thin. In addition, it not only has the characteristics of good heat insulation, visible light transmittance and anti-drip performance, but also has better heat preservation performance and longer service life than that of agricultural film without adding nano grain size blue tungsten oxide powder.
More importantly, the heat insulating film of nano grain size blue tungsten oxide powder can shield a certain amount of light that is invisible to our naked eyes ---ultraviolet light --- to prevent the flower from being sunburned in hot summer. Moreover, ultraviolet rays can be used for sterilization, which is more conducive to the growth of flowers, keeping them in good growth state, and opening beautiful flowers.
