PC architectural daylighting sheet
Problem Phenomenon
【Problem Phenomenon】Architectural daylighting needs high transparency, weather resistance and impact resistance
Cause Analysis
PC daylighting sheet (hollow/solid) is highly transparent and impact resistant (200 times that of glass), with weather-resistant coating, widely used in stadiums, stations and greenhouses；During on-site troubleshooting, verify item by item according to this mechanism, and avoid blindly adjusting the machine based solely on experience
Solution
Daylighting sheet selects weather-resistant coated PC; UV side installed facing outward; thermal expansion gap reserved；After adjustment, take continuous samples to verify the effect, and resume mass production only after confirming stability；Change only one variable at a time and record parameter changes to facilitate locating effective measures
Key Takeaway
PC daylighting sheet impact resistance 200 times that of glass, first choice for architectural daylighting；After confirming effectiveness, solidify the parameters and practices into the work instruction to prevent recurrence；Include this case in the defect archive as a reference for troubleshooting similar problems in the future
