2015new UV protection greenhouse automatic window opener with anti-fog

 greenhouse automatic window opener

Along with increasing demand on agricultural products,more and more technologies,new materails have been invested to this industry.

We use different roofing materials to make a compatible environment for many kind of vegetable,fruits,flowers and Chinese medicine herbs , to speed up their growth and maintain reliable and quality productions. the covering material changes from PE film to polycarbonate sheet , which means the development of our agriculture steps in a new stage.

why choose polycarbonate sheet for greenhouse automatic window opener ?(All Copyright reserved)

1.Transparency.

GoodLife clear transparent sheet have excellent light transmission and glossiness,and it will not change a lot with time goes on.

2. Impact Strengh.

It’s called “unbreakable glass”. For hollow profile, it’s 80 itmes as that of glass.

Impact strengh of GOODLIFE sheet is slightly better than GOODPOLY sheet.

3. UV-PC coextrusion layer.

The surface of Goodlife sun sheet is treated with high density special anti-ultraviolet  material to ensure the stability of ultraviolet resistance. 

4. Temperature  Resistance.

It’s low temperature embrittlement happens in-100℃, its hot temperature softening happens in 146℃. 

5. Thermal  Insulation.

The K-value of polycarbonate is 1/4 as that of glass, 1/300 as that of iron, 1/1000 as that of aluminum, 1/12000 as that of copper. It’s good for heat preservation so that to save heating energy. The structure of multi-wall sheet helps a lot. 

6. Energy Saving.

it’s called “energy saving building material”. The less the K-value is, the better result it is.  If the sheets is placed on the roof or on the window glass, keep distance 20-25mm, the result is even better. (All copyright reserved)

About the anti-fog polycarbonate sheet,

Anti-fog polycarbonate sheet means polycarbonate sheet with a kind of special,which is evenly painted on the downward surface to prevent moisture drops . When there is a big temperature difference between inside and outside, the tiny drops will be distributed evenly and flow down smoothly before gathering into a bigger drop, hich efficiently keeps the light transmission performance and protects the plants or animals inside. So it's specially used for large-scale greenhouse automatic window openers or eco-efficient hotel.

without anti-fog layer polycarbonate sheet :

On the surface of common sheet , the vapour coagulate fogdrops.

with an-fog layer polycarbonate sheet :

On the surface of Anti-fog sheet , the moisture soon gather to become a drop and flow down smoothly along the wall.
