PC board greenhouses are mostly Venlo type (can also be round arched), mostly with one span and multiple roofs, modern appearance, stable structure, beautiful and generous form, smooth vision, excellent thermal insulation performance, moderate light transmittance, rainy trough, large Span, large displacement, strong wind resistance, suitable for areas with heavy wind and rainfall. The PC board greenhouse has good light transmittance and low thermal conductivity. Because the PC board has light weight and high tensile strength, it can meet the requirements of wind resistance and snow resistance through a simple steel frame structure, beautiful and generous, reducing repeated construction and investment , Is currently the first choice to replace the original plastic film greenhouses and glass greenhouses. PC greenhouses are also widely used in facility agriculture, and are widely used in flower seedling cultivation, vegetable planting, and ecological restaurants.
1. PC board greenhouse style
The size of the spire pattern is usually two-pointed or three-pointed. The span of the solar panel greenhouse is 8 meters, 9.6 meters, and 12 meters. The height of the column generally ranges from 4 meters to 6 meters. The size of the sunshine board is generally fixed at 2 meters in width, and the length can be produced to a fixed length.
2. PC board greenhouse supporting system functions
Three, the advantages and disadvantages of PC greenhouse
1. The light transmittance can reach about 85%. With the addition of UV anti-aging coating on the outside of the PC board, the light transmittance will not drop by more than 10% within ten years; the internal dripping anti-fog coating can effectively reduce fogging and dew. Drop phenomenon.
2. Light weight, the weight per square meter of 8mm national standard sunshine board is 1.5kg, while the weight of 5mm tempered glass is 12.5kg.
3. Strong impact resistance, has the reputation of Xianggang. It has a good safety effect against hail and foreign objects falling.
4. The sound insulation effect is good, and it can be used in bending.
Fourth, the shortcomings of the sun panel greenhouse
Since the sunshine board is a plastic product, it has a certain service life. National standard high-quality products are guaranteed for ten years, which is ten years + life span. The non-standard cheap solar panel greenhouses are easy to turn yellow and dark after a few years, and the light transmittance drops a lot, which affects the normal use of the greenhouse. It is not recommended to use non-standard sunlight panels in agriculture.
