Venlo-pc Sheet Greenhouse
Greenhouse is venlo more sunshine board type (also canbe used in a circular arch), with more than a across the top, modern appearance, stable structure, form beautifuland easy, fluent, heat preservation performance is remark-able, light transmittance, moderate rain tank, large spanand large displacement, strong ability to resist wind, windand 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, greattensile strength, through a simple steel bone structure canmeet the requirements of wind resistance, KangXue, andlong service life, beautiful and easy, reduce repetitive con-struction and investment, is instead of the original plasticfilm greenhouse and glass greenhouse, the preferred products.
Features
The transmission of light: P C sunshine board light transmittance as high as 89%, comparable to glass. UV coating plateblasting bask in the sun won't produce yellowing, atomization, pervious to light, the transmission loss is only 10%, after tenyears of PVC turnover rate is as high as 15% - 20%, glass fiber was 12% - 20%.
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.
Anti-UV: one side of PC sheet is with anti-UV coating ,theother side with anti condensation treatment ,setting anti-Uvradiation heat insulation and anti droplet function in a body.lta body. lt can block ultraviolet rays through,and suitable forthe protection of valuable aret and exhibits, so that is not sub-ject to UV damage.
Light weight: only half the amount of glass, saving transportation, removing, installing and supporting the framework.
Fire retardant: national standard GB50222-95 confirms that the P C sunshine plate is a quandary, the B1 leve.lgnition point is 580 ℃, PC board itself from the self-extinguishing fire, burning will not produce poisonous gas, don't feed the fire from spreading.
Bending ability: can be designed to use cold bending mode at the site site, and be installed with vaulted,semi-circular top and window. Theminimum bending radius is 175 times the thickness of the plate.
Sound insulation sex: PC sunshine board sound insulation effect is obvious,than the same thickness and the strength of glass plate havebetter sound insulation,the thickness under the same con.ditions, the sound insulation quantty of P C sunshine board 5 --9 DP higher than that ofglass. Internationally, it is the first choice of highway soundproof barrier.
Energy-saving sex: XiaTianbao cool, heat preservation in winter, P C sun plate more than common glass and other plastic thermal conductivi-ty (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 ofheat is greatly reduced, and the buildings used for heating equipment are environmentally friendly.
Temperature adaptability: PC board cold short does not occur when to -40 ℃, 125 C when not soften ,is mechanics in the harsh environmentmechanical properties, etc. No obvious change.
Weather resistance: P C sunshine board can be - 40 ℃C to 120 C scope to keep the stability of the physcal indicators.The artifical weather-ag-ing test was 4, 000 hours, yellow was 2, and the transmittance decreased by only 0.6 percent.
Prevent dewing: outdoor temperature ℃, indoor temperature is 23 ℃C, the indoor relative humidity under 80% when ,the inner surtace of thematerial not condensation.The dew will move the surface of the plank, not dropping.
Easy and convenient: unlike traditional materials, which are bulky and widely used in the coastal cities of China in recent years.
