Anti Drip UV Protection Colorful Plastic Film for Greenhouse Covering refers to a special plastic film used in the construction of agricultural facilities. Its light transmittance, heat preservation, tensile strength and aging resistance are superior to those of ordinary agricultural film. It is of great significance to increase the yield and increase income of crops in greenhouses.
The structure of greenhouse film products should be multi-layer composite, and the performance should be integrated with high light transmission, high heat preservation, high strength, long life and continuous dripping period, fog-proof period, dust-proof period and other functions.
This kind of film has good light transmittance, the total light transmittance of the new film is over 85%, good moisture retention, low heat conductivity, high tensile strength and strong wind resistance. Good chemical stability, acid and alkali resistance.
Plastic film maintenance:
When deducting the membrane, try to avoid the mechanical damage of the shed film, especially the bamboo shed. Before the membrane is buckled, the protruding part of the surface of the frame should be flattened or wrapped with rag. When fixing with a spring, a layer of old newspaper should be placed at the card slot. Also pay attention to avoid long-term contact between new and old films, so as not to accelerate the aging of the new film. Be careful when ventilating. When the film is frozen or exposed, it will promote aging. The steel pipe is exposed to the sun in the summer, and the temperature can be raised to 60-70 ° C, thereby accelerating the aging and breaking of the film. During the use of the film, it is inevitable that there are holes, and it should be glued with adhesive or tape in time. Second, the environmental characteristics and regulation The greenhouse is covered by plastic film, forming a special microclimate that is relatively closed and exposed. For the cultivation of vegetable greenhouses, it is necessary to grasp the characteristics of the environment inside the greenhouse, and take corresponding control measures to meet the conditions for the growth and development of vegetables, so as to obtain high quality and high yield.
