The leisure ecological restaurant is a sunroom restaurant with greenhouse as the main building form. The sunroom ecological restaurant is covered with transparent color materials. Its purpose is to construct a natural and fresh dining environment. At present, most of the ecological restaurants in China use the pattern of the glass greenhouse to do, because the cost is economical, practical and beautiful, the construction speed is fast, the service life is long and so on. What I want to analyze today is why the roof of the greenhouse building of ecological restaurant chooses sunlight board as the covering material.
Let's first introduce the advantages of the sun board:
1. Anti-uv: the surface of the sun board PC board is treated with anti-uv technology, and the anti-uv layer thickness is greater than 50 microns. Uv protective layer penetrates the surface of the plate to ensure its long-term use. The light transmittance is minimized while maintaining long - term impact resistance and anti - aging.
2, to prevent indoor dripping: the sun board PC board inside of the special single-sided coating, after special treatment, can effectively decompose the plate surface produced by condensation; The condensate at the top drips down the sun plate into the dew trap.
3, super insulation: the sun board PC board with 8mm hollow or 10mm hollow form, with super thermal insulation, than the traditional method of heat insulation lighting energy saving up to 50%; Conducive to the ecological restaurant internal thermal insulation to reduce energy consumption.
4 and breakage resistance: the sunshine board PC board is a safe, high resistance to impact the daylighting of the material, compared with other greenhouse materials, impact resistance, strongest and not often need to change, as the aging or damaged under strong storm, hail and snow, under the condition of plate will not damage, so as to cut down the cost of replacement Drop hammer impact test: 10 kg heavy hammer, falling from 2 meters, no crack, no crack after impact. This also is an important factor that ecosystem dining-room chooses sunshine board, safe coefficient is tall.
5, high fire resistance: with good fire resistance, so it is more suitable than other plastic materials for greenhouse applications, its self-extinguishing can meet the fire standards of many countries; Difficult to burn rating difficult to burn a level.
6. Easy construction: the PC board is lighter than other materials, easy transportation and easy construction. Can be cold curved into an arc, the minimum bending radius is 175 times the thickness of the plate. Can maintain its perfect appearance for a long time. And the weight of the sun plate is very light, the weight of each square meter is 1.5kg, is 5mm tempered glass one eighth times.
The defect of sunshine board: the problem that USES fixed number of years, the manufacturer that gb is heavy sunshine board pledges fixed number of years to be 10 years, the proportion that qualitative content is the transmittance of sunshine board decreases in 10 years won't exceed 10%, and won't appear yellow change, brittle crack to wait for a phenomenon. But the quality of the sunshine board is not easy to check, there are also some with five years of warranty of the sunshine board as a ten years of warranty of the use of the sunshine board. Because this needs broad consumer when buying sunshine board must choose the sunshine board that brand manufacturer pledges.
