Yellow tungsten oxide nano powder may be applied for the preparation of thermal absorption agricultural plastic film due to its excellent infrared absorption ding. And the new agricultural film prepared not only has excellent heat absorbing ding, but also has good ultraviolet blocking ding. Then, how is this kind of infrared absorbing material particles (yellow tungsten oxide particles) applied to the preparation of agricultural film?
An infrared absorbing layer is formed on a surface of a desired substrate such as polypropylene, and the infrared absorbing layer is obtained by dispersing yellow tungsten oxide nanoparticles in a suitable medium formed by coating. The infrared absorbing material nanoparticles obtained by baking at a high temperature in advance are mixed into the film substrate. As the yellow tungsten oxide nanoparticles can be bonded to the surface of the substrate by a binder, they can be used for a substrate material with a low heat resistance temperature such as a resin material. Since it does not require a large device for production, it is not so expensive.
