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…
