Glass Greenhouse Smart Sun Panel Greenhouse
Sunshine panel greenhouses are mainly used for ecological restaurants, exhibition and sightseeing, scientific research experiments, demonstration and promotion, efficient planting (melon and fruits, vegetables, flowers and trees, Chinese medicinal materials, etc.), agricultural products exhibition and sales, efficient breeding (aquatic products, livestock and poultry, insects, etc.) Comprehensive cycle.
The main structure of the solar panel greenhouse:
The main body of the greenhouse mainly includes columns, purlins, side rails, arches, chord trusses, rain gutters (gutters), connectors, special aluminum profiles, seals, seals, fasteners, etc.; Q235 national standard high-quality carbon steel. Steel parts and fasteners are in accordance with "GB/T1912-2002 Metal Covering Layer, Technical Requirements and Test Methods for Hot-Dip Galvanized Steel Products". Good corrosion resistance, service life of more than 20 years. In order to meet the organized drainage of the gutter, single-end drainage is adopted, and the slope of the gutter is 3‰. The downpipe is made of PVC plastic pipe, diameter Ф110 mm
Cover material:
The top cover is made of polycarbonate hollow board with anti-ultraviolet light on the outer layer and anti-condensation on the inner layer. The surrounding walls are made of polycarbonate hollow board or glass according to the conventional requirements. etc.), the north wall can be made of thermal insulation composite panels, and sliding windows can be installed to increase the ventilation area of the greenhouse.
Solar panels have the following characteristics:
(1) Light transmittance: The light transmittance of PC solar panel can reach up to 89 percent , which can be beautiful with glass. UV coated board will not produce yellowing, fogging and poor light transmission under sunlight exposure. After ten years, the loss of light transmission is only 10 percent , the loss rate of PVC is as high as 15 percent -20 percent , and the loss rate of glass fiber is 12 percent . percent -20 percent .
(2) Impact resistance: The impact strength is 250-300 times that of ordinary glass, 30 times that of acrylic sheets of the same thickness, and 2-20 times that of tempered glass. There is no crack when dropped from two meters below a 3kg hammer. Glass" and "Sound Steel".
(3) Anti-ultraviolet: One side of the PC board is co-extruded with anti-ultraviolet (UV) coating, and the other side has anti-condensation treatment, which integrates the functions of anti-ultraviolet, heat insulation and anti-fog droplets. It blocks UV rays from passing through and is suitable for protecting valuable artwork and exhibits from UV damage.
(4) Light weight: the specific gravity is only half of that of glass, saving the cost of transportation, handling, installation and supporting the frame.
(5) Flame retardant: The national standard GB50222-95 confirms that the PC solar panel is a flame retardant grade 1, that is, B1 grade. The ignition point of the PC board is 580 degree , and it will self-extinguish after leaving the fire. No toxic gas will be produced when burning, and it will not contribute to the spread of the fire.
(6) Bendability: According to the design drawing, the cold bending method can be adopted on the construction site, and it can be installed into an arch, semi-circular top and window. The minimum bending radius is 175 times the thickness of the plate, and it can also be hot bent.
(7) Sound insulation: PC solar panel has obvious sound insulation effect, and has better sound insulation than glass and sub-afterburner of the same thickness. Under the same thickness, the sound insulation of PC solar panel is 5-9DB higher than that of glass. . Internationally, it is the best material for highway noise barriers.
(8) Energy saving: keep cool in summer and keep warm in winter, PC solar panel has lower thermal conductivity (K value) than ordinary glass and other plastics, and the thermal insulation effect is 7 percent -25 percent higher than that of the same glass. thermal insulation up to 49 percent . Therefore, the heat loss is greatly reduced, and it is an environmentally friendly material for buildings with heating equipment.
(9) Temperature adaptability: PC board does not become cold and brittle at -40 degree , does not soften at 125 degree , and its mechanics and mechanical properties have no obvious changes in harsh environments.
