GREENHOUSE SCREEN |
摘要 |
<p>A greenhouse screen with high light resistance and good weathering characteristics. The purpose is to achieve a greenhouse screen which combines the characteristics of a shadow curtain and a blackout curtain and in certain cases also an energy curtain. These goals have been achieved through letting the screen at least partly consist of a material which in one or more layers is sunshine absorbing in a significant part of the wavelength interval 575 - 800 nm, preferably with a maximum in the interval 600 - 750 nm, while the photosynthes light of the sunshine in the wavelength interval 400 - 575 nm is mainly transmitted through the material.</p> |
