Application of functional greenhouse film

<< Back >>

In recent years, with the rapid development of agricultural high-tech in my country and the rapid promotion of greenhouse agriculture, the demand for agricultural film for greenhouses has increased sharply, but the general single-layer PE The film has low light transmittance, small elasticity and low UV resistance; although the general single-layer EVA film has excellent elasticity, it is not resistant to high temperature. Now, a new type of agricultural film - multi-functional agricultural special three-layer PEP co-extruded agricultural film is quietly entering the market. This kind of agricultural film is a co-extrusion type (PE+EVA+PE sandwich method) three-layer composite film made by overcoming and improving the shortcomings of the general agricultural film, so as to preserve the original advantages and eliminate its shortcomings. In addition to using additives such as anti-aging, anti-fogging, and thermal insulation, it also uses a new generation of high-tech polyolefin catalyst Metallocence to make the agricultural film thinner and stronger. Compared with other common agricultural film, the product has a long service life (1-3 times), a long anti-drip life (3-4 times), good thermal insulation effect, biological control and thermal insulation and cooling functions. Multi-functional agricultural special agricultural films include: gold, silver, copper and other multi-color films, rose films and red fluorescent films for rose cultivation, biological control films, thermal insulation and cooling films and other multi-functional agricultural greenhouse special agricultural films membrane. As soon as the product came out, it was favored by consumers for its unique color and special function.
1. Durability: As we all know, the aging of any substance is caused by the irradiation (destruction) and oxidation of the sun's ultraviolet rays, and the multi-functional agricultural special agricultural film contains 15% - 35% more resistance than the general PE film. UV stabilizer, thus extending its useful life. Its longest service life can be up to 5 years, which varies with different climates. Specially formulated agricultural film can meet the needs of different customers.
2. Light transmittance: The light transmittance can reach 92%, and can be adjusted according to actual needs.
3. High refractive index: multi-functional special films with different refractive indices can be produced according to actual needs. Generally divided into three types: no refractive index - less than 25%; medium refractive index - between 25% - 40%; high refractive index - between 40% - 60% .
4. High temperature and strong wind resistance: Because it has both the temperature resistance of PE and the toughness of EVA, it can resist high temperature and strong wind.
5. Dustproof: After electrostatic treatment, the surface is free of static electricity, and it is not easy to absorb dust.
6. Anti-ultraviolet: The multi-functional special agricultural film is treated with two kinds of ultraviolet formula, so it has excellent anti-ultraviolet physical properties, and the service life can be up to 5 years.
7. Heat preservation: The multifunctional special agricultural film can also be made into a film with excellent heat preservation by a special formula. At night, the thermal insulation film can still retain 75%-85% of the far infrared rays, which is more effective than the general non-insulation film which can only retain 40%-45% of the far infrared rays.
8. Anti-fog: The multi-functional special agricultural film contains a special additive, which can reduce the surface tension of the film and allow the water droplets condensed by the fog to flow down from both sides of the film without forming fog and dew, and stay in the film. on the film.
