From PE Greenhouse Covers
PE greenhouse films; that are used to to prepare a controllable environment and provide suitable conditions for plant grow, are the most important material of greenhouse applications with cartier replica watches their flexibilites, strengths, easy installations, additive acceptance and being economics. They are produced in different lifetime and in different properties according to the regions, crop types, crop properties and requirements.
- They are flexible and can be shaped, easily closed greenhouse skeleton.
- Application is cheaper and easier.rolex replica watches
- Various alternetive of covers by production with the usage of some additives like UV, AF, IR etc.
- More economic than other greenhouse cover materials.
UV additive increases the usefull lifetime of the film. Depends on the film thickness, desired life-time of the film and the region that the film will be used, different type and amount of UV Stabilizers are used.
These stabilizers determines the type and life-time of the greenhouse films as 9,12,24,36 and 60 months.
During nights and cold days, IR additive decreases heat loss by 2-5 0C by keeping the heat inside greenhouse.
IR additive protects the plants from frost, protects from stres and improves plant development. In addition to these, IR provides energy savings in greenhouse heating.
AF (AntiFog) provides the moisture condensed on the film surface forming uniform water layer and this prevents the water droplets falling on the plants.
EVA increases the transparency of the film, provides high strength and flexibility.
Anti Dust prevents the decrease in light transmission of the film by preventing accumulation of the dust on outer surface of the film.
AV additive prevents insect mobility and some fungi development inside greenhouses.
LD (Light Diffuser)
LD additive provides the some portion of sunlight entering inside greenhouse to be diffused and this results in beter plant development and prevents sunburn of the plants.
