Q

LLDPE drying judgment

A

LLDPE drying is executed as needed, regrind must be baked; After confirming effectiveness, fix the parameters and practices into the work instruction to prevent recurrence; include this case in the defect archive as a reference for troubleshooting similar problems in the future.

Material Drying LLDPE drying regrind bubbles

Q

LLDPE temperature upper limit

A

LLDPE's temperature upper limit also exists; the 280℃ red line plus residence management prevents oxidative degradation; After confirming effectiveness, fix the parameters and practices into the work instruction to prevent recurrence.

Processing Machinery LLDPE; temperature upper limit; 280℃; thermal oxidation; degradation

Q

LLDPE rotational molding powder quality

A

The particle size uniformity of rotational molding powder is the premise of wall thickness consistency; 35 mesh is the benchmark for particle size management; After confirming effectiveness, fix the parameters and practices into the work instruction to prevent recurrence.

Q

LLDPE '2079851475616104452 temperature management

A

LLDPE '2079851475616104452 temperature management is stricter than LDPE; the viscosity sensitivity of narrow MWD requires finer temperature control; After confirming effectiveness, fix the parameters and practices into the work instruction to prevent recurrence.

Injection Molding LLDPE; '2079851475616104452 temperature; 200-260℃; ±5℃; precision

Q

LLDPE extrusion temperature 195-215℃

A

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.

Extrusion & Post LLDPE; extrusion temperature; 195℃; 215℃; gel

Q

LLDPE die gap 0.060-0.10

A

The die gap is the equipment dividing line between LLDPE and LDPE; the 2-3 times difference must be reflected in the changeover procedure; After confirming effectiveness, fix the parameters and practices into the work instruction to prevent recurrence.

Material Analysis LLDPE; die gap; 0.060-0.10 inches; back pressure; material changeover

Q

LLDPE melt temperature 200-260℃

A

LLDPE's wide temperature window reflects process friendliness; but high-temperature residence also causes degradation, and leniency does not mean no boundary; After confirming effectiveness, fix the parameters and practices into the work instruction to prevent recurrence.

Production & Quality LLDPE; melt temperature; 200-260℃; 280℃; degradation

Q

LLDPE non-hygroscopic drying

A

LLDPE drying is moisture prevention rather than dehydration; sealed storage is primary, and damp material recovers with 80℃×1-2h; After confirming effectiveness, fix the parameters and practices into the work instruction to prevent recurrence.

Material Drying LLDPE; drying; non-hygroscopic; 80℃; silver streaks

Q

LLDPE film process record management

A

Record management is the soft power of the quality system; data capitalization can accelerate problem solving.; After confirming effectiveness, fix the parameters and practices into the work instruction to prevent recurrence.

Processing Machinery LLDPE; film; process records; traceability; standardization; management

Q

LLDPE film bubble shaking troubleshooting

A

Shaking troubleshooting must be systematic; the item-by-item isolation method is more reliable than experience guessing.; After confirming effectiveness, fix the parameters and practices into the work instruction to prevent recurrence; include this case in the defect archive as a reference for tr...
