Single Span Film Greenhouse For Vegetable Growing-Jianchuan

The installation method of sunshine board greenhouse

To build a greenhouse greenhouse first steel support, available pipe or tube to do steel, steel can also be made of steel, in general, sunshine plate shed are made arc, which is conducive to the top of the drainage, to remind everyone The spacing should not be too wide, otherwise the installation will lead to board sagging.

The External Shading System-Jianchuan Greenhouse

      First, the sun plate should be bent along the direction of the force, must not bend the horizontal. Bending radius of the plate thickness: 175 times the hollow two-tier plate, the following three-tier board 185 times, four times the board about 200 times. The strength of the solid endurance plate is also less than 175 times the thickness of the thickness. Plate bending parts are strictly prohibited with screws.
      Second, in the installation of hollow plate and solid endurance board, the board and board joints, must be based on sheet size reserved thermal expansion gap, thermal expansion coefficient of 0.065mm / m ℃, is strictly prohibited self-tapping, rivets and other direct through the plate fixed. If it is necessary to pass through, it must be perforated on the plate diameter greater than 100% of the diameter of the self-tapping or rivet riveting hole, and then reduce the self-tapping or rivet through the expansion of the center of the hole to ensure that the plate can be free in any direction
        The Third, contact with the sun plate sealant must use neutral silicon copper glue, is strictly prohibited the use of alkaline, acidic, chemical composition of the solvent containing the sealant. To avoid direct contact with chemical solvents, solutions and volatile gases, if the use of thinner dilution paint spray sunshine board support frame, must be completely dry with paint before the installation of sun panels, is strictly prohibited with thin paint diluted brush has been installed Sun plate steel skeleton.

Twin Wall Polycarbonate (PC) Sheet Greenhouse

        Fourth, the sun board installation must be fixed with the company's special anti-dripping up and down sets of fasteners or the company to provide special flat pressure, if the use of other companies flat sheet must ensure that the material is EPDM rubber or rubber, Polyvinyl chloride (PVC), natural rubber and other materials containing harmful substances on the sun plate.
        Fifth, the installation of light board must be UV coextrusion UV anti-UV layer with a text protective film side to the outside, must not be installed anti-installed immediately after the completion of the protective film immediately to avoid the sun after exposure to protective film And the sun plate adhesion.
6, before installation should be opened from the edge of about 30mm range of protective film, is strictly prohibited under the protective film in the profile, and then cut the protective film with a knife to open the film method. Any part of the sunboard can not be scratched.7, sun section cut section with aluminum foil tape or waterproof breathable tape sealed, so as not to water vapor dust and insects into the air, affecting the sun board transparency and aesthetics.
