Main features of thin film shed

      Thin film ShedIs one of the construction forms of greenhouse shed, this kind of shed is very low cost, and the construction is relatively convenient, is the current agricultural shed construction is very good choice, this structure greenhouse shed is not affected by the season, more suitable for the growth of crops, adapt to a variety of growth environment.

Thin film shed main structure using hot-dip galvanized coffin, covering materials using plastic film (the top of the use of imported drip-free film, the surrounding use of imported longevity film). Hot-dip Galvanized light steel structure is used. The top is covered with double-decker inflatable film or single-layer film and can be surrounded by double-layer inflatable films, single-layer films or other flexible covering materials. Generally speaking, the interior space is large, the snow load is high, the hood is few, also has the suspension function, therefore the construction cost is lower. The transmittance is stable, not only good water vapor, good anti-aging resistance, large greenhouse lighting area, uniform indoor light, indoor spacious and bright, large operating space, high greenhouse utilization rate, beautiful and beautiful, strong ornamental, greenhouse has a strong decorative. Strong drainage capacity, can be a large area of multi-span. Can be used in scientific research experiments, flower market, ecological hotel, high-end flower planting seedlings.

The main characteristics of thin film continuous greenhouse are simple structure and flexible form. Simple multi-span membrane greenhouse is to remove the configuration of some multi-span membrane greenhouse, mainly applicable to grape shielding, strawberry cultivation, crop seedling and so on. It mainly has the following two characteristics. Simple structure: Due to the characteristics of covering materials, plastic shed load-bearing structure, thin film fixing system, installation requirements are relatively simple. Its bearing structure adopts hot-dip galvanized light steel or ordinary steel structure, generally using hot-dip galvanized light steel structure, assembly structure is very good. Flexible size and variety: Due to the structural characteristics of multi-span greenhouse, coupled with the development process of large plastic film greenhouse, affected by geography, customer demand and other factors, all countries in the world according to their own standards for public relations. Popularization and popularization of plastic shed.

The membrane is easily damaged during use and preservation and can be temporarily repaired during use. There are two methods: one is to fill the water method, wipe the damaged area clean, cut into a slightly larger film than the broken area, dipped in the water paste on the hole, discharge the air between the two layers of film, according to the plane can be, the other is the paper filling method, slightly damaged. ED agricultural film, dipped in water stickers in damaged areas, can generally be used for about 10 days. The damaged film should be repaired. The thicker film is damaged and can cover the same film and is connected to thin lines and seams. Can also clean the damaged parts, cover the hole with a slightly larger film, and then cover with 2-3 layers of newspaper, with the iron along the interface gently ironed, two layers of film heated and pasted together, cooled into a hot patch. In addition, there is a method of dispensing, cleaning around the hole, with a brush dipped in a special glue smear, 3-5 minutes later, take a film of the same texture placed on top, glue can be firmly glued dry. Heat repair and dispensing have a good repair effect. Membrane repair is not only leaking, but also easy to pull open. It is best not to use thick film.

The location of multi-span greenhouses should be as flat as possible, the water table should not be too high, to avoid mountains and buildings shading, polluted areas can not build greenhouses. In addition, the wind resistance of greenhouse greenhouses should be considered in strong monsoon areas. In general, the wind resistance of a greenhouse should be above 8. The greenhouse direction of solar greenhouse has a great influence on greenhouse heat storage capacity. Planting greenhouses suggests a north-south orientation, with greenhouse heads on both sides of the south and north, allowing crops in greenhouses to distribute even light.
