Yellow nano tungsten oxide may be added to the production of polyvinyl chloride film (PVC film) so that the thermal absorption agricultural plastic film may be prepared. As you may have known, although PVC has a certain thermal absorption performance, the agricultural film produced by PVC material generally has a high transmittance, so the thermal absorption property of the agricultural film is not so good.
While if the PVC agricultural plastic film is produced by adding a certain amount of nano grain size yellow tungsten oxide powder, the film will have high thermal absorption performance as well as high visible light transmittance. Also, such agricultural plastic film of yellow tungsten oxide nanoparticles has good ultraviolet shielding performance. Besides, the toughness, strength and many other characteristics of the PVC film are improved. Therefore, the agricultural plastic film obtained may be widely applied in the greenhouse as a lot of plants need just such environment for better growth.
