Tungsten Oxide Nanopowder Applied for Heat Insulation Agricultural Thin Film 50

Tungsten oxide nanopowder may be added in the preparation of common agricultural film to obtain heat insulation agricultural thin film. As you may have known, common agricultural film is not good for fogging in winter, and it is easy to produce dew when it is released, which results in high humidity in the shed. And it is not conducive to disease prevention. Moreover, it needs to be replaced frequently, which is not conducive to environmental protection. But, experts have found…

Information
Nano Tungsten Oxide Applied for Heat Insulation Agricultural Thin Film 62

Nano tungsten oxide may be used for the preparation of heat insulation agricultural thin film. This is mainly because the tungsten oxide nanoparticles have an excellent ultraviolet blocking effect. In other words, these nanoparticles can well block ultraviolet rays from the outside which are excessive for plants in the greenhouse. Therefore, an appropriate amount of long ultraviolet rays that are irradiated into the greenhouse can stimulate the growth of plants, increase crop yield, and promote the synthesis of proteins, sugars,…

Information
Yellow Tungsten Oxide Nanopowder Applied for Thermal Absorption Agricultural Plastic Film 61

Yellow tungsten oxide nanopowder may be used for the preparation of thermal absorption agricultural plastic film. Since the infrared absorbing material nanoparticles (yellow tungsten oxide nanoparticles) are electrically conductive materials, when these infrared absorbing material particles are connected to form a continuous film, it is possible to absorb and reflect wave, and then the radio waves of mobile phones will be blocked. However, when the infrared absorbing material is made into nanoparticles and dispersed in the base material, these nanoparticles…
