Yellow tungsten oxide nano powder may be applied for the preparation of thermal absorption agricultural plastic film due to its excellent infrared absorption ding. And the new agricultural film prepared not only has excellent heat absorbing ding, but also has good ultraviolet blocking ding. Then, how is this kind of infrared absorbing material particles (yellow tungsten oxide particles) applied to the preparation of agricultural film? An infrared absorbing layer is formed on a surface of a desired substrate such as…

Nano grain size yellow tungsten oxide may be used for the preparation of thermal absorption agricultural plastic film. The new agricultural film not only has excellent infrared absorption ding (thermal absorption property or thermal insulation property), but also has the characteristics of high visible light transmittance and aging resistance. And the transparent film is waterproof, anti-fog and anti-dripping. As you may have known, the common agricultural film has water droplets. And it is not sufficiently insulated. While the new agricultural…

Nanometer cesium tungsten bronze is an inorganic nano-material that has a good absorption effect on near-infrared rays, and thus it may be used as a raw material for preparing ceramic microsphere such as heat insulating ceramic microsphere. Therefore, such dingal ceramic microsphere may be applied to automobile film, transparent heat-insulating architectural window film, building coatings, and so on. The reason why the nano grain size cesium tungsten bronze powder has good heat insulating effect is because the powder has infrared…

Nanometer cesium tungsten bronze may be applied for producing nano-ceramic color master. This is because the nano particle size cesium tungsten bronze powder has strong absorption properties in the near-infrared region at the wavelength range of 800-1200nm and high transmittance in the visible light region at the wavelength range of 380-780nm, so that a new dingal ceramic color master can be prepared. At present, the new dingal nano ceramic color master of nano grain size cesium tungsten bronze powder has…

Nano yellow tungsten oxide is an infrared absorbing material, which may be added to the production of polyvinyl fluoride film for preparing a new type of thermal absorption agricultural plastic film. As you may have known, different colors of agricultural plastic film have different performance on absorption, refraction and reflection of light, and thus have different effects on various crops. Therefore, farmers hope that manufacturers can produce a variety of colored agricultural plastic film to meet the needs of different…

Yellow tungsten oxide powder (WO3) may be applied in the production of low density polyethylene agricultural film to obtain thermal absorption agricultural plastic film. As you may have known, low-density polyethylene film has high transparency and good heat sealability. And it is also waterproof and moisture-proof. However, the low-density polyethylene film has low tensile strength and large tensile elongation, which make it prone to wrinkles. And it is particularly susceptible to deformation when heated, resulting in difficulty in color registration.…

Yellow tungsten oxide powder may be applied to the production of thermal absorption agricultural plastic film in the form of an infrared absorbing layer. This is a new type of composite agricultural film. The new agricultural plastic film of yellow tungsten oxide is mainly obtained by coating yellow tungsten oxide nanoparticles in a production process of blown polyethylene film, cast polyethylene film or extrusion coated polyethylene film. Certainly, there are many other types of agricultural plastic films on the market,…

Yellow tungsten oxide may be added to the production of PE agricultural film to improve the thermal absorption effect (heat preservation effect) of the film, and therefore a new type of thermal absorption agricultural plastic film may be obtained. As you may have known, PE film has the characteristics of moisture resistance, high transparency and low moisture permeability. According to different manufacturing methods and control methods, PE film can be divided into low density PE film, medium density PE film…

Yellow nano tungsten oxide may be added to the production of polyvinyl chloride film (PVC film) so that the thermal absorption agricultural plastic film may be prepared. As you may have known, although PVC has a certain thermal absorption performance, the agricultural film produced by PVC material generally has a high transmittance, so the thermal absorption property of the agricultural film is not so good. While if the PVC agricultural plastic film is produced by adding a certain amount of…

Yellow tungsten oxide nanopowder may be added to the polyethylene agricultural film to prepare heat insulation agricultural film with better performance. As you may have known, polyethylene film has high transparency, high strength, water resistance, moisture resistance, impermeability and strong tensile properties. Such film is also breathable, which can effectively separate moisture and exhaust hot air and moisture, so it is beneficial to the growth of plants in the greenhouse. And therefore, nano yellow tungsten oxide powder may be used…
