PBAT foamed material
Problem Phenomenon
PBAT foaming processing, cell structure and density control.
Cause Analysis
PBAT foaming agent selection; cell nucleation; temperature and pressure; density control; mechanical properties.; when troubleshooting on site, verify item by item according to this mechanism, and avoid blindly adjusting the machine based only on experience
Solution
①Foaming agent type; ②process parameters; ③density optimization; ④performance testing; ⑤application matching.; after adjustment, continuously sample to verify the effect, and resume mass production only after confirming stability
Key Takeaway
PBAT foaming is a functionalization direction; cell structure determines performance; testing ensures application.; after confirming effectiveness, solidify the parameters and practices into the work instruction to prevent recurrence
