Yellow tungsten oxide may be added to the production of PE agricultural film to improve the thermal absorption effect (heat preservation effect) of the film, and therefore a new type of thermal absorption agricultural plastic film may be obtained. As you may have known, PE film has the characteristics of moisture resistance, high transparency and low moisture permeability. According to different manufacturing methods and control methods, PE film can be divided into low density PE film, medium density PE film and high density PE film. In either case, the heat absorption of these PE films is generally not very good.
Therefore, some experts have discovered in the process of studying the thermal absorption film that if a certain amount of yellow tungsten oxide nanoparticles is added to the common PE agricultural film, the prepared agricultural plastic film will have good heat absorption effect. In other words, the soil in the greenhouse can be fully heated, which is good for the growth of plants.
