LLDPE film metallocene upgrade
Sorun Belirtisi
Ordinary LLDPE performance reaches a bottleneck; evaluate the mLLDPE upgrade.
Neden Analizi
mLLDPE has a narrow molecular weight distribution and uniform comonomer distribution; strength, transparency, and heat sealing are comprehensively better than conventional LLDPE; but the processing window is narrower.; During on-site troubleshooting, verify item by item according to this mechanism, avoiding blindly adjusting the machine based only on experience.
Çözüm
①Evaluate mLLDPE grades; ②adjust processing temperature and screw configuration; ③add PPA to improve processing; ④verify performance improvement.; After adjustment, continuously sample to verify the effect, and resume mass production only after confirming stability.
Temel Çıkarım
mLLDPE is the performance upgrade direction; processing adaptation is the key to successful switching.; After confirming effectiveness, fix the parameters and practices into the work instruction to prevent recurrence.
