Polycarbonate sunshine board installation manufacturer
For the polycarbonate board, lift up the protective film along the edge and leave the position of the bead so that the bead polycarbonate sheet directly touches the board. After the installation of the PVC gusset is completed, the maintenance film is completely torn off. Do not remove the maintenance film. After the sheet of the film is installed, the protective film is cut along the edge of the bead. Because it is so simple to leave a scratch on the sheet, the sheet will crack along the scratch. If screws are used to fix the solar panel, the aperture should be more than 0.5 times the diameter of the screw to prevent heat and cold from shortening and deforming and damaging the panel.
Do not touch the polycarbonate sheet with corrosive chemical solvents to prevent damage to the sheet. Please use a neutral detergent or non-aggressive detergent to scrub with water to prevent the appearance of unique marks. The joint of the two plates needs to reserve a satisfactory elastic space according to the change of the temperature difference in the field. Under normal circumstances, the gap width is more than 50% of the screw diameter.
Please use special sealant, other types of sealant may corrode the board, making the board brittle and simply cracking. PVC seals will corrode the board. When installing the sunshine board, it is necessary to choose sealant paste and rubber pads suitable for polycarbonate plastics, and it is strictly prohibited to use PVC seals and gaskets. Avoid touching alkaline substances and aggressive organic solvents on the board surface, such as alkalis, amines, ketones, aldehydes, ethers, halogenated hydrocarbons, aromatic hydrocarbons, formaldehyde propanol, etc.
It is forbidden to drill the board screws directly during the construction process. The screw holes should be drilled first, and then the screws should be installed. If the plate needs tortuous shape, screw on the tortuous stress point is forbidden. In order to allow the displacement of the plate expansion during the drilling device, the drilling diameter should be greater than 50% of the screw diameter and the distance between the screw hole and the edge of the plate should not be less than 50mm. The screw cannot be tightened too tightly. The screws should not be too dense. It is recommended to use one screw every 50cm or more.
