Violet tungsten oxide nanopowder may be used for the preparation of heat insulation agricultural film. As you may have known, common agricultural film, or agricultural plastic film, whose main component is polyethylene, can be used to cover farmland, to improve ground temperature, maintain soil moisture, and promote seed germination and rapid growth of seedlings. At the same time, it also has the effect of inhibiting the growth of weeds.
However, these agricultural films do not have good thermal insulation properties. In other words, in the summer, these agricultural films can not meet the growth requirements of some plants in the greenhouse. While the agricultural film added with violet tungsten oxide nanoparticles has excellent heat insulation effect (58% blocking rate of 380nm ultraviolet light), so that these plants in the greenhouse can grow well even at high temperature.
Besides, the new agricultural film of violet tungsten oxide also has good tensile strength, high aging resistance, good light transmittance and good herbicidal, deworming, moisturizing and fat-retaining effects. In addition, the film does not contain any filler or old materials, in line with the national standards of agricultural film.
