PBAT equipment corrosion
Problem Phenomenon
PBAT processing equipment corrosion, erosion by acidic degradation products.
Cause Analysis
PBAT degradation produces acidic substances; high-temperature processing accelerates; equipment material; anti-corrosion treatment; maintenance cycle.; when troubleshooting on site, verify item by item according to this mechanism, and avoid blindly adjusting the machine based only on experience
Solution
①Corrosion-resistant equipment material; ②optimize processing temperature; ③regular maintenance; ④anti-corrosion coating.; after adjustment, continuously sample to verify the effect, and resume mass production only after confirming stability
Key Takeaway
PBAT equipment corrosion is a long-term production problem; material and maintenance are equally important; temperature management reduces degradation.; after confirming effectiveness, solidify the parameters and practices into the work instruction to prevent recurrence
