Heat insulation agricultural film may be prepared by adding a certain amount of yellow tungsten oxide powder. And the comprehensive performance of the agricultural film may be improved as yellow tungsten oxide particles have excellent ultraviolet blocking effect. The yellow tungsten oxide used is nano grain size yellow tungsten oxide of infrared absorbing nanoparticles. And these nanoparticles can form an infrared light absorbing layer so that yellow tungsten oxide nanopowder can be applied to prepare a weather-resistant and low-cost agricultural film. More important, just a small amount of yellow tungsten oxide particles is needed to efficiently absorb the near-infrared rays from sunlight through agricultural film.
What should be noted is that agricultural film covering technology is widely used in rural areas nowadays, and farmers can apply it many times in order to improve economic efficiency. Therefore, you need to know how to store agricultural film of yellow tungsten oxide for next use. For example, using water storage method. The used agricultural film is washed and dried, then rolled into bundles or stacked, placed in a tank or a pool, pressed on the mulch, poured into the water to flood the film, and then added cover for the sunshade. During storage, the tank cannot be dehydrated.
