Violet tungsten oxide powder may be applied for the preparation of thermal absorption agricultural plastic film. At present, blown polyethylene film is a widely used and low-cost agricultural film, which has certain heat preservation, chemical stability, moisture resistance and many other characteristics. However, its heat absorption and heat insulation performance are not very good. Therefore, experts are studied to find that if a certain amount of violet tungsten oxide nanoparticles are added to the polyethylene film, it can have better…

Violet tungsten oxide may be used for the preparation of thermal absorption agricultural plastic film. Although this new type of agricultural film is called the “thermal absorption” agricultural film, it also has the ding of heat insulation. And these two characteristics are mainly attributed to the infrared absorption and ultraviolet blocking properties of the violet tungsten oxide nanoparticles. In addition, the agricultural film enhanced with nano grain size violet tungsten oxide powder has the advantages of better strength, toughness, wind…

Violet nano tungsten oxide may be used for the production of thermal absorption agricultural plastic film, which has excellent infrared (can be converted into heat) absorption effect, thereby warming the soil, but at this time, the temperature in the greenhouse does not rise. In addition, the agricultural film reinforced with violet tungsten oxide nanoparticles also has the characteristics of better anti-aging performance, higher temperature resistance, higher strength and longer service life. Take the high temperature resistance of the new agricultural…

Violet tungsten oxide nanopowder may be used for the preparation of heat insulation agricultural film. As you may have known, common agricultural film, or agricultural plastic film, whose main component is polyethylene, can be used to cover farmland, to improve ground temperature, maintain soil moisture, and promote seed germination and rapid growth of seedlings. At the same time, it also has the effect of inhibiting the growth of weeds. However, these agricultural films do not have good thermal insulation properties.…

Violet tungsten oxide nano powder may be applied for producing heat insulation agricultural film, which has a certain heat insulation effect and has excellent heat preservation performance. And therefore such agricultural film can be applied to flowers shed or greenhouse for the heat insulation of flowers that need to be moved in the greenhouse in cold winter. The flowers are containing potted camellia, brown bamboo, rhododendron, smile, Zhu Dinghong, and so on. In the Yangtze River Basin, these potted flowers…

Nano grain size violet tungsten oxide may be used to prepare heat insulation agricultural film. The prepared agricultural film is a type of nano inorganic composite agricultural film with excellent heat insulation performance and anti-ultraviolet radiation performance. It can be used in greenhouse or greenhouse supporting system such as double-arched double-film greenhouse, which is suitable for planting cucumber, tomato and many other fruits or vegetables. It can also be used for planting dwarf fruit trees. As you may have known,…

Nano violet tungsten oxide may be used for the preparation of heat insulation agricultural film. As you may have known, the agricultural film can be used in the double arch double membrane greenhouse supporting system. This kind of greenhouse system is equipped with external shading system, internal shading system (heat insulation system), fan curtain cooling system, heating system, and water curtain outer film ventilation system. Moreover, the greenhouse is covered with double-layer film on the top. It does not increase…

Violet tungsten oxide powder may be used for the preparation of heat insulation agricultural film. Wherein, the violet tungsten oxide used is nano grain size violet tungsten oxide, which can enhance the strength, toughness, heat insulation, light transmission, heat preservation, wind resistance and anti-drip performance of the obtained agricultural film. Therefore, the service life of the new heat insulating agricultural film is much longer than that of general agricultural film. And therefore the agricultural film adding with violet tungsten oxide…

Violet tungsten oxide powder may be used for the preparation of heat insulation agricultural film, which is mainly applied to greenhouses such as flower greenhouses. The reason why such agricultural film has heat insulation performance is because the violet tungsten oxide nano particles can effectively block ultraviolet rays and have strong infrared reflection performance, thereby preventing ultraviolet rays from harming crops, and enhancing the thermal insulation performance of the agricultural film. So, how is the agricultural film applied to the…

Violet tungsten oxide may be used to prepare a composite agricultural film — heat insulation agricultural film. As you may have known, with the development of agricultural technology, the demand for agricultural film has shown a rapid upward trend. At the same time, agricultural greenhouses have put forward higher requirements for the performance of agricultural film. And therefore, in recent years, violet tungsten oxide nanoparticles have attracted the attention of many researchers as nano grain size violet tungsten oxide has…
