Tungsten Trioxide for Mulch

 In addition to the production of tungsten trioxide (WO3) ultrafine particles, they can be used to produce tungsten powder, tungsten carbide powder, yellow ceramics, electrode materials for energy storage batteries, anti-corrosion paints and coatings, and can also be used to make multifunctional mulch films. Compared with ordinary agricultural film, the agricultural film containing tungsten oxide additives has higher comprehensive performance, which is mainly manifested in better heat insulation effect and better light transmission performance.

In areas with strong sunlight, when the temperature is too high, it is easy to produce drought and cell dehydration, which affects the physiological and metabolic activities of plants, such as photosynthesis, water metabolism, endogenous hormones, and thermal stability of cell membranes, which in turn leads to the appearance and growth of plants abnormal. Therefore, it is of practical significance to produce agricultural film with good heat insulation effect. However, a film with excellent heat insulation effect means that it has better near-infrared absorption performance.

In addition to good heat release effect, the new thermal insulation film also needs to have excellent light transmittance, so that it is convenient for managers to observe the production of crops at any time, without lifting the film, which improves the work efficiency of managers. At the same time, it can also reduce the rate of film breakage. The agricultural film with excellent light transmittance means that it has a higher transmittance to visible light.

WO3 is a classic transition metal n-type semiconductor material. It has excellent optical properties, that is, it has a significant absorption effect on near-infrared light in the 1400~1600nm and 1900~2200nm bands, and it also has high permeability to visible light. Therefore, it is favored by materials researchers at home and abroad. It is often used as a key modifier for commercial mulch films, which can significantly increase the near-infrared absorption capacity and light transmittance of the product, which is more conducive to the growth of crops.
