Introduction of Glass Greenhouse

Most plastic film greenhouses are dome shaped, and the roof and surrounding environment are covered with imported PEP composite long-life anhydrous film. The large span of the greenhouse and the spacious and bright rooms are well ventilated, providing more space for indoor facilities and personnel flow. The main structure after assembly is the hot-dip galvanized frame to ensure the overall corrosion resistance of the greenhouse frame. The main arch, concrete sill and column are made of hot-dip galvanized rectangular steel frame. The main arches of open rooms are hot dip galvanized. All fittings are bolted and the high flow flume is mounted on top of the span column. Covering materials can be combined in many ways. For example, the vertical surface around the greenhouse can be covered with hollow PC solar panels to enhance insulation and impact resistance. Other materials, such as float glass, can also be used to stubbornly demonstrate their effects and extend their service life. The top plastic film can be single layer or double layer, providing users with more choices. The film can be used as a greenhouse for seedling production. It is used to grow flowers, vegetables and young plants. There are many kinds of covering materials. The suitability of greenhouse depends on its nature. It is suitable for different units and different climatic regions. In other words, users can choose covering materials and supporting equipment according to their own economic strength and use, so as to achieve their own use purposes.

How to extend the greenhouse lifespan

1. Film thickness

The thicker the film is, the longer it will resist aging. The aging of PE material is caused by ultraviolet radiation. Therefore, it is necessary to select the agricultural film with UV absorber and UV stabilizer in the formula. The agricultural film acts with UV absorber acts is used as black protective layer. Ultraviolet light is absorbed and converted into heat. UV stabilizers can effectively prolong the aging time of agricultural films and even repair the damaged molecular structure.

2. Climate temperature

3. Chemicals

In particular, some pesticides and fungicides containing sulfur or chlorine will destroy the quality stability of agricultural films. If sulfur is used for fumigation of greenhouse gases, sulfur compounds must be prevented from burning. Because sulfide can seriously shorten the service life of agricultural film. When burning sulfur, attention should be paid not to exceed 160 ℃ to effectively prevent the formation of sulfur compounds.

4. Installation method

When the agricultural film is not tightened, aging often occurs. When the wind comes, the agricultural film will continuously and rapidly hit the bone, thus damaging the agricultural film. Therefore, the agricultural film must be evenly tensioned when installing the agricultural film. If the outdoor temperature then drops below 10 ° C, the agricultural film should be tightened again after a period of time as the temperature rises.
