Dark Blue Nano Tungsten Oxide Applied for Thermal Absorption Agricultural Plastic Film 75

Dark blue nano tungsten oxide may be applied for producing thermal absorption agricultural plastic film. The obtained agricultural thin film is a type of nano thermal insulating agricultural film with the characteristics of relative high visible light transmittance, infrared shielding rate and appropriate ultraviolet transmittance. In order to obtain agricultural film with excellent heat insulating effect, some experts have specially conducted research on agricultural film with the addition of blue tungsten oxide powder. They found that the nano heat insulation…

Blue Tungsten Oxide Nanopowder Applied for Heat Insulation Agricultural Film 81

Blue tungsten oxide nanopowder may be applied for preparing heat insulation agricultural film, which has the advantages of anti-corrosion, acid resistance, alkali resistance, corrosion resistance. Also, it is anti-fog and anti-aging with long service life. In addition, the thickness of the obtained agricultural film conforms to the national mandatory standard thickness of agricultural film — 0.008mm. Although many of the agricultural films sold on the market are 0.004mm, they do not meet the requirements of agricultural film standard. If these…

Blue Tungsten Oxide Nano Powder Applied for Heat Insulation Agricultural Film 82

Blue tungsten oxide nano powder may be applied for producing heat insulation agricultural film. As you may have known, the main component of agricultural thin film is polyethylene, which is used in greenhouses such as flower greenhouses, vegetable greenhouses and crop greenhouses to play an important role of heat preservation and moisturizing. Also, such film can inhibit weed growth. But, it does not have a good thermal insulation effect. Moreover, some agricultural films have poor ultraviolet light (UV) passing rate,…

Nano Grain Size Blue Tungsten Oxide Applied for Heat Insulation Agricultural Film 74

Nano grain size blue tungsten oxide may be applied for producing heat insulation agricultural film. Although polyethylene film and polyester film have been widely used as greenhouse membranes, and they can also play a role in improving ground temperature, maintaining soil moisture, promoting seed germination, rapid growth of seedlings, and inhibiting weed growth. However, the heat insulation effect of these agricultural films is not very satisfactory. And this will cause problems such as wilting and scorching of plants in the…

Nano Blue Tungsten Oxide Applied for Heat Insulation Agricultural Film 87

Nano blue tungsten oxide may be applied for preparing heat insulation agricultural film, and thus be applied to greenhouses such as agricultural greenhouses. However, there are many greenhouse membranes that have no heat insulation ding, which makes the temperature stability in the greenhouse relatively poor, which is not conducive to the growth of crops. Just then, experts found that: If a certain amount of nano grain size blue tungsten oxide powder is added to these greenhouse films, these films can…

Information
Heat Insulation Agricultural Film: Blue Tungsten Oxide Powder, WO2.9 84

Blue tungsten oxide powder is a new material that may be used to produce heat insulation agricultural film. And the transparent agricultural film is mainly for use in flower greenhouses. The thickness of such film is very thin. In addition, it not only has the characteristics of good heat insulation, visible light transmittance and anti-drip performance, but also has better heat preservation performance and longer service life than that of agricultural film without adding nano grain size blue tungsten oxide…

Information
Blue Tungsten Oxide Powder Applied for Heat Insulation Agricultural Film 72

Blue tungsten oxide powder may be applied to produce heat insulation agricultural film, and therefore be applied in agricultural greenhouses. We all know that the crops planted in agricultural greenhouses are mostly crops that are shade-requiring plants. And excessive ultraviolet light rays (UV) can be harmful to such crops. For example, such plants are more prone to sunburn in the summer, resulting in sunburn and the like. However, the heat insulating agricultural film adding with nano particle size blue tungsten…

Information
Blue Tungsten Oxide Applied for Heat Insulation Agricultural Film 77

Blue tungsten oxide may be applied for preparing heat insulation agricultural film. And the heat-insulating thin film obtained has good visible light transmittance with a certain ultraviolet light shielding rate. What is more important is that it does not form a partitioning environment for excessive ultraviolet rays, which is unfavorable for crop growth. That is to say, the heat-insulating film can satisfy the illumination required for plant growth, and is therefore widely used in flower greenhouses, agricultural greenhouses, and so…

Information
Blue Nano Tungsten Oxide Applied for Heat Insulation Agricultural Film 84

Blue nano tungsten oxide may be applied for producing heat insulation agricultural film, which has a certain shielding effect on ultraviolet rays while ensuring high visible light transmittance. Since such heat insulation thin film does not completely block the ultraviolet rays, a part of the ultraviolet rays can still be irradiated to the plants through the film. In other words, this kind of insulation film does not affect the growth of plants, vegetables or flowers in agricultural greenhouses. We all…

Information
Blue Tungsten Oxide Nano Powder Applied for Thermal Absorption Agricultural Plastic Film 63

Blue tungsten oxide nano powder may be applied for producing thermal absorption agricultural plastic film. The agricultural plastic film obtained has the characteristics of visible light transmittance of 86%~92% and haze less than 0.8%. Also, it is anti-fog. Besides, such film has a thickness of 0.008mm, which meets national mandatory standards. In addition, the transparent agricultural film produced by adding nano grain size blue tungsten oxide powder has a certain anti-ultraviolet ding, so that the ultraviolet rays irradiated through the…
