Yellow tungsten oxide nanopowder may be added to the polyethylene agricultural film to prepare heat insulation agricultural film with better performance. As you may have known, polyethylene film has high transparency, high strength, water resistance, moisture resistance, impermeability and strong tensile properties. Such film is also breathable, which can effectively separate moisture and exhaust hot air and moisture, so it is beneficial to the growth of plants in the greenhouse. And therefore, nano yellow tungsten oxide powder may be used in the production of agricultural film.
If a layer of infrared absorbing material (nano yellow tungsten oxide particles) is applied to one side of such an agricultural film to form an infrared absorbing layer, a new type of agricultural film is prepared, which can insulate and absorb heat without affecting the demand for light of plants. Moreover, the performance of the film such as toughness and strength is also improved.
