Blue tungsten oxide nano powder may be applied for producing heat insulation agricultural film. As you may have known, the main component of agricultural thin film is polyethylene, which is used in greenhouses such as flower greenhouses, vegetable greenhouses and crop greenhouses to play an important role of heat preservation and moisturizing. Also, such film can inhibit weed growth. But, it does not have a good thermal insulation effect. Moreover, some agricultural films have poor ultraviolet light (UV) passing rate, which will affect crop growth.
Therefore, some experts have achieved the purpose of improving the thermal insulation properties of the obtained agricultural film by adding a certain amount of nano grain size blue tungsten oxide powder to these agricultural films. Moreover, since the heat-insulating film is transparent, it does not affect the transmission of visible light. So, the illumination requirements required for crop growth in the greenhouse can be satisfied.
