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…
