Tungsten oxide powder may be used for the preparation of thermal absorption agricultural plastic film, which has good heat preservation effect and heat insulation effect. And thus such thermal absorption film has a wider range of uses. The obtained agricultural plastic film has the advantages of stronger toughness, strength and wind resistance than the general agricultural film. So, the new agricultural plastic film of tungsten oxide has long service life with excellent performance. In other words, in the preparation of…

Tungsten oxide is a kind of infrared absorbing material nanoparticles that may be used for the preparation of thermal absorption agricultural plastic film such as agricultural land cover films, horticultural land cover films and greenhouse films. The infrared absorbing material nanoparticles are tungsten oxide nanoparticles and/or composite tungsten oxide nanoparticles. The new agricultural film will form an infrared light absorbing layer, which will absorb infrared light and block a certain amount of ultraviolet light without affecting the passage of visible…

Nano tungsten oxide may be used for the preparation of thermal absorption agricultural plastic film, such as the preparation of agricultural and horticultural land cover film. The obtained agricultural film is an infrared light absorbing layer containing infrared absorbing material nanoparticles. And the infrared absorbing material nanoparticles are tungsten oxide nanoparticles and/or composite tungsten oxide nanoparticles. And the tungsten oxide nanoparticles are tungsten oxide nanoparticles represented by the general formula WOX (2.45≤X≤3), and composite tungsten oxide nanoparticles is represented by…

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…

Tungsten oxide nano powder may be added in the production of a polyethylene film to obtain a heat insulation agricultural thin film. As you may have known, polyethylene film has many characteristics, showing as below: 1.0 Good light transmission, no plasticizer pollution, nice light transmittance and strong low temperature resistance. Low temperature embrittlement temperature is 70°C. 2.0 It is light in weight, 0.92, which is only equivalent to 76% of polyvinyl chloride. 3.0 Infrared transmittance is as high as 87%…

Tungsten oxide powder (WO2) may be used for the preparation of heat insulation agricultural thin film. And the obtained agricultural film has high visible light transmittance, high infrared shielding rate and suitable ultraviolet shielding rate to achieve a certain heat insulation effect. It does not affect the light requirements of the plants in the greenhouse. In such a greenhouse, the temperature is suitable and the amount of ultraviolet light is appropriate, and thus it is advantageous for the growth of…

Tungsten oxide powder is a kind of new nano heat-insulating material, which may be applied for the production of heat insulation agricultural thin film. The new agricultural film is mainly composed of two parts. One part is a transparent resin layer and the other part is a transparent base film. And the nano heat-insulation material is mainly applied to the transparent resin layer in the preparation process of agricultural film. Further, such a heat insulating material of tungsten oxide can…

Tungsten oxide is a nano heat insulation material that may be used in the preparation of heat insulation agricultural thin film. The new nano heat-insulation agricultural film comprises a transparent base film and a transparent resin layer, wherein the resin layer contains nano grain size tungsten oxide material. And the nano heat insulation material has a blocking ratio of 85% or more of 780nm wavelength of infrared rays, 60% of 380nm ultraviolet rays and more than 95% of transmittance of…

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,…

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…
