PPSU transparency retention
Problem Phenomenon
PPSU maintains transparency at high-temperature service; optical application advantage.
Cause Analysis
PPSU transparent slightly yellow; maintains transparency at high temperature; optical performance; thermal aging; application verification.; During on-site troubleshooting, verify item by item according to this mechanism, and avoid blindly adjusting the machine based solely on experience
Solution
①Transparent grade selection; ②high-temperature verification; ③optical testing; ④aging evaluation.; After adjustment, continuously sample 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
PPSU high-temperature transparency is a unique advantage; verification ensures application; testing ensures quality.; After confirming effectiveness, solidify the parameters and practices into the work instruction to prevent recurrence
