What to pay attention to when installing polycarbonate board
The polycarbonate board is either dry assembly method or wet assembly method, whether it is installed horizontally, vertically or inclined. The most important thing in the installation of polycarbonate panels is the fastening of the edges. The clamped part of the solar panel must contain at least one arrow rib, or the meshed part of the edge of the solar panel must be at least 20mm. There must be an effective space in the connecting profile or in the inserting groove of the frame to allow the solar panel to be expanded and displaced under load. The linear thermal expansion coefficient of the hollow solar panel is 7×10m/mk, that is, for every 1℃ increase in temperature, the 1m×1m solar panel expands by 0.075mm along the length direction. The user must calculate the temperature difference according to the four seasons of the project location and the transparent pc board. Installation clearance data: For example, in the northern area, the highest temperature is 40℃, polycarbonate sheet is quoted, and the low temperature is -30℃. The reserved clearance for 1m×1m plate installation is 0.07×70u003d4.9mm
