LLDPE extrusion temperature 195-215℃
Sorun Belirtisi
LLDPE film shows gel and uneven thickness; fluctuation remains after temperature adjustment.
Neden Analizi
LLDPE film extruder barrel 195℃ and die head 215℃ are the benchmark; uneven temperature produces gel; low die head temperature brings high melt fracture risk; heater bands and thermocouples need regular calibration.
Çözüm
①Barrel 195℃, die head 215℃ benchmark settings; ②regular calibration of heater bands and thermocouples; ③check filtration and degradation when gel is excessive; After adjustment, continuously sample to verify the effect, and resume mass production only after confirming stability.
Temel Çıkarım
LLDPE film temperature is the golden combination of 195/215; equipment state calibration is more important than blindly adjusting temperature; After confirming effectiveness, fix the parameters and practices into the work instruction to prevent recurrence.
