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...
