Product Description

Plastic film greenhouse is a kind of greenhouse structure with plastic film as the main covering material, which is widely used in agricultural cultivation and other fields.

 

Product Description

Frame part
It is usually composed of metal materials (such as steel pipes and galvanized pipes). The pipes are cut, bent and welded to form the skeleton of the greenhouse. The diameter and wall thickness of the steel pipe are determined according to the size of the greenhouse and the design carrying capacity. For example, small greenhouses may use steel pipes with a diameter of 25-32mm, and large greenhouses may use pipes with larger diameters and thicker walls to ensure the stability of the structure and be able to withstand plastic films, snow, wind loads and other weights.
Frames come in a variety of shapes, with common arches and ridges. The frame of the arch greenhouse is circular, which can make the plastic film better covered, the force is more uniform, and the internal space is relatively open. The ridge greenhouse is similar to the ridge shape of the house, has certain drainage advantages, and is more flexible in the use of space, which is suitable for some planting methods that require higher space.

 

Plastic film
It is a key covering material for greenhouses. Commonly used plastic films are polyethylene (PE) film and polyvinyl chloride (PVC) film. PE film price is relatively low, good flexibility, high light transmittance, generally around 85%-93%, and puncture resistance is also good. The thermal insulation performance of PVC film is better than that of PE film, and its light transmittivity can reach 80%-90%, but the price is slightly higher, and over time, its plasticizer may leak out, affecting the performance of the film.
The thickness of the plastic film also has a variety of options, generally between 0.08-0.2mm. Thicker films are more durable, but the cost will increase accordingly. The color of the film is also different, transparent film has the best light transmission, which is conducive to plant photosynthesis; There are also some films with special pigments, such as blue films, which can regulate the light quality to a certain extent and have a special promotion effect on the growth of some plants.

 

Ventilation system
Natural ventilation is one of the common ventilation methods of plastic film greenhouse. This is generally achieved by setting vents on the side walls or roofs of greenhouses. The side wall vents can be manually opened plastic steel Windows or rolled film vents controlled by film rollers. The roll film vent is easy to operate, and the size of the vent can be adjusted according to needs. The roof vent usually adopts the roof ridge ventilation method, and the ventilation window is set at the roof ridge. The hot air in the room is discharged by using the principle of hot air rising to achieve the purpose of ventilation and cooling.
Mechanical ventilation systems are also used in some large plastic film greenhouses. It is mainly composed of fans and ventilation pipes. The fan is usually installed on one side of the greenhouse, and the ventilation pipe is distributed inside the greenhouse, and the fresh air pumped by the fan is evenly distributed to all corners of the greenhouse. This method has high ventilation efficiency, but the equipment cost and operating cost are relatively high.

 

Sunshade system
Sunshade net is the main component of plastic film greenhouse sunshade system. Sunshades can be installed inside or outside the greenhouse. The advantage of the internal sunshade net is that it is easy to install and maintain, and the disadvantage is that the sunshade effect is slightly poor. The external sunshade has a better shading effect, which can directly block sunlight onto the plastic film and reduce the accumulation of heat inside the greenhouse, but it is susceptible to natural factors such as wind and rain, and requires a more robust installation structure.
According to the different shading rate, the shading net has a variety of specifications, such as 40%, 60%, 80% shading rate. For some plants with low light intensity requirements, such as edible fungi and flower seedlings, you can choose a sunshade net with a higher sunshade rate to avoid damage to plants caused by strong light.

 

Insulation system
In addition to the thermal insulation effect of the plastic film itself, some plastic film greenhouses will also use thermal insulation to enhance the thermal insulation effect at night. Insulation quilt is usually composed of multiple layers of materials, such as needled cotton, insulation felt and so on. At night, thermal insulation is covered with plastic film by electric or manual coiling devices to reduce heat loss.

 

Product characteristics

 

Lower cost
Compared with glass greenhouses and polycarbonate sheet greenhouses, the construction cost of plastic film greenhouses is much lower. The plastic film itself is cheap, and the frame structure is relatively simple, and the material cost and installation cost are relatively low. This makes plastic film greenhouse in agricultural production more easily accepted by the majority of farmers, especially suitable for small and medium-sized farmers.

Good light transmission
Transparent plastic film can provide good natural lighting conditions, so that the greenhouse interior light is sufficient, conducive to plant photosynthesis. Moreover, the light transmission performance of plastic film can be adjusted by selecting different film materials and thicknesses to meet the requirements of different plants for light intensity and light quality.

Construction flexibility
The size and shape of the plastic film greenhouse can be flexibly designed according to the actual site and planting needs. It can be a small simple greenhouse for home gardening or small seedling breeding; It can also be a large multi-storey greenhouse for large-scale vegetable and flower planting. The assembly of the frame structure is relatively simple and the construction period is short.
