Characteristics And Performance Characteristics Of Film Multi-span Greenhouse

In recent years, the utilization rate of greenhouses has become higher and higher. The film multi-span greenhouse is also a kind of greenhouse derived from it. Compared with other greenhouses, its performance characteristics and other aspects have been greatly improved. The characteristic of the film multi-span greenhouse structure is that its outer surface is covered with a film, which is connected by several independent greenhouses, which can not only keep warm and moisturize, but also increase the ground receiving area. The application range of the film multi-span greenhouse is also very wide, and it can be used in various agricultural facilities.
1. Single-layer film flower greenhouse The multi-span greenhouse is also called the arched film multi-span greenhouse. It is a multi-span greenhouse that connects a single arched greenhouse with columns. Because the span between the two columns is 8m, the span between the two columns is 4m, and the column height is 3m, it is called a multi-span greenhouse. The multi-span film greenhouse consists of a main frame, a film covering material, an external shading system, an internal shading system, a fan water curtain cooling system, a top film winding ventilation system, and a side film winding ventilation system.
2. Double-layer film multi-span flower greenhouse The main frame of the greenhouse is the round arch on the right side of the bottom of the outer arch, and then a layer of inner film is added around the greenhouse to cover the top and sides of the greenhouse with double-layer film. The column height of traditional multi-span greenhouses is generally about 3 meters, while the column height of multi-arch double-film greenhouses in some countries is increased to about 5 meters or 6 meters, which increases the height of the internal space. The interior of the greenhouse is divided into two insulation spaces by a double-layer film, which improves the insulation performance of the greenhouse.
The advantage of PO film is that it has a long service life. 15 lines can be used for about 5 years, and 8 lines can be used for about 3 years. The film has good light transmittance, heat preservation and drip resistance.Polytunnel Plastic Greenhouses
