PEI Ultraviolet and Gamma Radiation
Problem Phenomenon
Performance of PEI changes in outdoor or radiation environment applications; the ultraviolet and gamma radiation resistance characteristics need working condition matching.
Cause Analysis
PEI resists ultraviolet and gamma radiation; but specific dose and time have influence; color and mechanical properties are evaluated separately; protective measures are enhanced.; during on-site troubleshooting, verify item by item according to this mechanism, and avoid blindly adjusting the machine based only on experience
Solution
①Verify performance according to radiation dose; ②track color and mechanical properties separately; ③protective coating when necessary; ④accumulate application data in radiation environments.; after adjustment, continuously sample to verify the effect, and resume mass production after confirming stability
Key Takeaway
PEI's radiation resistance broadens applications; the dose and time dimensions need refinement; dual-indicator tracking is comprehensive.; after confirming effectiveness, fix the parameters and practices into the work instruction to prevent recurrence
