Hydroponic greenhouse automatic polycarbonate greenhouse for agricultural planting
Multi span plastic film green house
-European structure, multi span commercial film green house for agriculture
1. Brief Introduction
The plastic film green house, bringing about fabulous social or economic benefits, is a kind of simple and practical equipment for cultivation or breeding, easy to construct, convenient to use and low cost, applied widely on the cultivation of vegetables, fruits, flowers and breeding of aquatic products and poultry
as well as scientific experiences all around the world with the development of plastic-film industry. It is able to provide the conditions of suitable illumination, moisture and temperature, raising the output and resisting the natural disasters. It is also able to bring forward or backward the provision, remitting the contradictions of provision and demand.
2. Structure and Configuration
The skeleton is equipped with the thin steel tubes linked with the appropriate connectors. The section of the upright is circular, rectangular and U-shaped. About the roof, the framework is arched or inverted-V-shaped, accessible to be equipped with the suitable gutters. All of the mental material, many types, is two-side hot-galvanized, rust-resisting, standard and originally produced.
The facilities that are fitted for it can be the film-reeling ventilation system or the roof row-rack ventilation system and the A-type rack-pinion screening system as well as the side cooling-pad ventilation system. The greenhouse can also be equipped with some facilities such as fans and furnaces,etc.
The covering material is the plastic film, thickness of 0.08mm-0.15mm, PE or EVA, colorless and semi-transparent.
The main body can be in service for more than 10 years.
3. Characteristics
• inner large room, convenient operation, easy to construct and accessible to remove.
• accessories rust-resisting, strong ability to resist the snow and wind as the whole.
• high transmission rate, great heat-retaining property and hermetic ability.
