PBAT thickness reduction
Fenómeno do problema
Insufficient strength after PBAT film thinning, breaking in use, contradiction between cost and performance.
Análise das causas
PBAT strength is low and thickness demand is large; mechanical properties insufficient after thinning; stress in use conditions; safety margin; cost pressure.; when troubleshooting on site, verify item by item according to this mechanism, and avoid blindly adjusting the machine based only on experience
Solução
①Blend modification to improve strength before thinning; ②evaluate use conditions; ③safety margin design; ④multi-layer structure optimization.; after adjustment, continuously sample to verify the effect, and resume mass production only after confirming stability
Conclusão principal
PBAT thinning is a trade-off between cost and performance; modification is the technical support; evaluation ensures safety.; after confirming effectiveness, solidify the parameters and practices into the work instruction to prevent recurrence
