Greenhouse project

Venlo-pc sheet greenhouse

Greenhouse is venlo more sunshine board type (also can be used in a circular arch), with more than a across the top, modern appearance, stable structure, form beautiful and easy, fluent, heat preservation performance is remarkable, light transmittance, moderate rain tank, large span and large displacement, strong ability to resist wind, wind and rain are suitable for large area. Sunlight greenhouse, has a good penetrability, low heat conduction coefficient, because the sunshine board weight is light, long life, great tensile strength, through a simple steel bone structure can meet the requirements of wind resistance, KangXue, and long service life, beautiful and easy, reduce repetitive construction and investment, is instead of the original plastic film greenhouse and glass greenhouse, the preferred products.

Features

（1）The transmission of light: PC sunshine board light transmittance as high as 89%, comparable to glass. UV coating plate blasting bask in the sun won't produce yellowing, atomization, pervious to light, the transmission loss is only 10%, after ten years of PVC turnover rate is as high as 15% - 20%, glass fiber was 12% - 20%.

（2）The impact resistance: impact strength is common glass of 250-300 times, 30 times that of the same thickness of acrylic, 2-20 times that of toughened glass, the following two meters with 3 kg hammer drop no crack, there are "no broken glass" and the "ring of steel" laudatory name.

（3）Anti-UV: one side of PC sheet is with anti-UV coating ,the other side with anti condensation treatment ,setting anti-UV radiation heat insulation and anti droplet function in a body.It a body. It can block ultraviolet rays through,and suitable for the protection of valuable aret and exhibits, so that is not subject to UV damage.

（4）Light weight: only half the amount of glass, saving transportation, removing, installing and supporting the framework.

（5）Fire retardant: national standard gb50222-95 confirms that the P C sunshine plate is a quandary, the B1 level. Ignition point is 580 ℃, PC board itself from the self-extinguishing fire, burning will not produce poisonous gas, don't feed the fire from spreading.

（6）Bending ability: can be designed to use cold bending mode at the site site, and be installed with vaulted, semi-circular top and window. The minimum bending radius is 175 times the thickness of the plate.

（7）Sound insulation sex: PC sunshine board sound insulation effect is obvious, than the same thickness and the strength of glass plate have better sound insulation, the thickness under the same conditions, the sound insulation quantity of P C sunshine board 5 -- 9 DP higher than that of glass. Internationally, it is the first choice of highway soundproof barrier.

（8）Energy-saving sex: Xia Tianbao cool, heat preservation in winter, P C sun plate more than common glass and other plastic thermal conductivity (K value), heat insulation effect between 7% and 25% higher than the same glass and P C sunshine board insulation up to 49%. The loss of heat is greatly reduced, and the buildings used for heating equipment are environmentally friendly.

（9）Temperature adaptability: PC board cold short does not occur when to -40 ℃, 125 ℃ when not soften, its mechanics in the harsh environment, mechanical properties, etc. No obvious change.

（10）Weather resistance: PC sunshine board can be - 40 ℃ to 120 ℃ scope to keep the stability of the physical indicators. The artificial weather-aging test was 4, 000 hours, yellow was 2, and the transmittance decreased by only 0.6 percent.

（11）Prevent dewing: outdoor temperature 0℃, indoor temperature is 23 ℃, the indoor relative humidity under 80% when, the inner surface of the material not condensation. The dew will move the surface of the plank, not dropping.

（12）Easy and convenient: unlike traditional materials, which are bulky and widely used in the coastal cities of China in recent years.
