Nano blue tungsten oxide may be used to produce thermal absorption agricultural plastic film, which has good heat absorption effect and ultraviolet light blocking effect. And such transparent film is also transparent with high visible light transmittance. Therefore, the film is applied in flower greenhouses, vegetable greenhouses and many other different greenhouses.
As you may have known, there is ultraviolet light in the sun. It affects almost all living things, especially microbes. Microorganisms that are exposed to a dose of ultraviolet light will be killed within ten minutes. Therefore, a certain amount of ultraviolet light can be used for sterilization. However, excessive UV exposure can cause plants to wilted or even die.
Therefore, experts have found that the addition of a certain amount of blue tungsten oxide nanoparticles to the agricultural film can have a higher UV blocking rate and visible light transmission rate, which is exactly needed for vegetables or flowers in the greenhouse.
