Tungsten oxide nano powder is a new type of nano inorganic material with a hexagonal crystal structure, which may be used for preparing thermal absorption agricultural plastic film. And therefore, such agricultural plastic film of thermal absorption performance may be applied to agricultural greenhouses, garden greenhouses, and the like. Experts have discovered that tungsten oxide nanoparticles can perform good infrared absorption in the process of studying dingal agricultural film. There is agricultural film produced by dispersing the infrared absorbing nano…

Tungsten oxide powder may be used for the preparation of thermal absorption agricultural plastic film. And the obtained agricultural plastic film can achieve the purpose of improving the temperature in the greenhouse or the shed in cold winter without improving the transparency of the reinforced film. This is because tungsten oxide nano particles added into the agricultural film have an excellent infrared absorbing effect, so that the ground temperature in the shed or greenhouse can be maintained at a temperature…

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…
