Nano yellow tungsten oxide is an infrared absorbing material, which may be added to the production of polyvinyl fluoride film for preparing a new type of thermal absorption agricultural plastic film. As you may have known, different colors of agricultural plastic film have different performance on absorption, refraction and reflection of light, and thus have different effects on various crops. Therefore, farmers hope that manufacturers can produce a variety of colored agricultural plastic film to meet the needs of different crops.
In this regard, experts in the development of multi-color agricultural plastic film found that a transparent agricultural plastic film may have the performance of multi-color agricultural film, to meet the various needs of crops, such as heat preservation, heat insulation and herbicidal ding. Also, experts found the film of yellow tungsten oxide nanoparticles can prevent premature aging of crops. And such a transparent film is obtained by adding a certain amount of yellow tungsten oxide nano particles during the production of the common agricultural film.
