LLDPE film antiblock agent fouling
Sorun Belirtisi
High antiblock agent formulation film has severe die lip buildup.
Neden Analizi
Inorganic antiblock agents (such as diatomaceous earth) accelerate abrasive fouling at the die exit; the problem is prominent at 3000ppm-level addition.; During on-site troubleshooting, verify item by item according to this mechanism, avoiding blindly adjusting the machine based only on experience.
Çözüm
①Add PPA to suppress buildup; ②optimize antiblock agent type and dosage; ③regularly clean the die exit; ④evaluate organic antiblock alternatives.; After adjustment, continuously sample to verify the effect, and resume mass production only after confirming stability.
Temel Çıkarım
The conflict between antiblock agent and buildup can be resolved with PPA; there is also optimization room at the formulation level.; After confirming effectiveness, fix the parameters and practices into the work instruction to prevent recurrence.
