Nano grain size blue tungsten oxide may be applied for preparing thermal absorption agricultural plastic film. The so-called agricultural film is the agricultural plastic film, which refers to a thin agricultural film that directly covers the cultivated alfalfa or the ground, and generally has a thickness of 0.008 to 0.015mm. In recent years, various colored agricultural films have been listed. Due to the different absorption and reflection patterns of different colors of agricultural film, the effects on crop growth and weeds, pests and diseases, and ground temperature are also different. Therefore, considering different crop characteristics and planting season, different colors of agricultural film should be chosen to achieve better results.
For example, compared with the conventional agricultural film, the transparent agricultural film obtained by adding nano particle size blue tungsten oxide powder has a blocking ratio of 80% or more of infrared rays of a wavelength of 780nm-2400nm, a blocking ratio of 58% of ultraviolet rays of 380nm, and a transmittance of 93% or more of visible light.
