Blue nano tungsten oxide may be applied for producing heat insulation agricultural film, which has a certain shielding effect on ultraviolet rays while ensuring high visible light transmittance. Since such heat insulation thin film does not completely block the ultraviolet rays, a part of the ultraviolet rays can still be irradiated to the plants through the film. In other words, this kind of insulation film does not affect the growth of plants, vegetables or flowers in agricultural greenhouses.
We all know that the lethality of ultraviolet light is extremely strong. Excessive ultraviolet radiation is extremely harmful to the growth of some plants. While if the amount of ultraviolet ray is appropriate, it is indispensable for the suppression of harmful bacteria and the prevention and control of pests and diseases. And this effect can be achieved by using an heat insulating film adding with nano grain size blue tungsten oxide powder.
