In recent years, polycarbonate roofing panels have been widely used due to their long service life, good thermal insulation performance, strong thermal insulation ability, and reasonable price. As a result, there are many inferior polycarbonate sheets, which confuse people's choice of polycarbonate. Let's take a look at how to choose the polycarbonate roofing panels :
1. Watch burning. Select a small PC solid sheet for the combustion test, and a good quality PC solid sheet will extinguish itself after it is far away from the fire source.
2. Look at the light transmittance of the sheet. The PC solid sheet produced by imported new materials such as Lexan, and Makrolon has the best light transmittance, no crystal points on the surface, and no impurities and pits inside the sheet. Several samples of PC solid sheets can also be placed on a white the paper, the PC solid sheet produced from recycled materials is dark and has pitting on the surface, while the imported new material produced has good light transmittance, is transparent and shiny, and has no pitting on the surface.
3. The anti-fog and UV-protected polycarbonate can be self-discriminated UV is a key factor that causes the aging of the panels. Therefore, more and more manufacturers are now choosing to co-extruded UV protection layers. UV layer solar panel, the UV layer of a good quality hollow polycarbonate cannot be measured only by the thickness, but also to see the uniformity of its co-extrusion. It is necessary to choose twin wall polycarbonate sheets with a good UV layer thickness and uniformity. The identification of anti-fog twin wall polycarbonate is actually very simple. Take a cup of hot water and put it under the panel. If the condensed water forms fog or water droplets on the lower surface of the panel, it means that the anti-fog effect is not good.
4. The installation and construction are neglected. Choosing a good-quality clear twin-wall polycarbonate is only the first critical step. Installation is a more critical step. Edge sealing and punching are the key factors that determine the quality of the solar panel installation technology. If it is not installed well during the installation process, then It will damage the service life of the solar panel, so the installation process must not be taken lightly.
I hope that you will not be misled in the process of purchasing polycarbonate roofing sheets. You must distinguish carefully and choose good-quality polycarbonate panels.
