LLDPE film winter production fluctuation
Fenómeno do problema
Bubble stability and thickness deviation problems increase in winter.
Análise das causas
Low ambient temperature makes cooling too strong and uneven; low raw material temperature also affects plasticization stability.; During on-site troubleshooting, verify item by item according to this mechanism, avoiding blindly adjusting the machine based only on experience.
Solução
①Adjust the cooling air volume to adapt to the ambient temperature; ②preheat the raw material or store with heat preservation; ③monitor bubble temperature; ④establish winter process cards.; After adjustment, continuously sample to verify the effect, and resume mass production only after confirming stability.
Conclusão principal
Seasonal factors cannot be ignored; environmental compensation and seasonal process cards are countermeasures.; After confirming effectiveness, fix the parameters and practices into the work instruction to prevent recurrence.
