Q

Unreasonable die head flow channel design of polyolefin plastomer extruders (Variant: Enhanced Measures)

A

The die head flow channel design needs to ensure uniform melt distribution and no stagnation, and the die head should be redesigned when necessary. Targeted preventive measures need to be taken in different production scenarios.

Q

Ovality of polyolefin plastomer pipes exceeding the standard (Variant: Enhanced Measures)

A

Excessive ovality is caused by uneven cooling or external force deformation, and needs to be solved from cooling uniformity and pipe storage. Targeted preventive measures need to be taken in different production scenarios.

Q

Mechanical properties of polyolefin plastomer extruded products not up to standard (Variant: Enhanced Measures)

A

Mechanical properties not up to standard are caused by material degradation or poor processing quality, and need to be solved from temperature control and plasticization quality. Targeted preventive measures need to be taken in different production scenarios.

Q

Excessive gel/gel particles in polyolefin plastomer extruded products (Variant: Enhanced Measures)

A

Gel is caused by insufficient plasticization or raw material quality problems, and needs to be solved from temperature control, screw design, and raw material selection. Targeted preventive measures need to be taken in different production scenarios.

Q

Bending deformation of polyolefin plastomer extruded pipes (Variant: Enhanced Measures)

A

Pipe bending is caused by non-uniform cooling or hauling eccentricity, and needs to be solved from cooling uniformity and equipment alignment. Targeted preventive measures need to be taken in different production scenarios.

Q

Uneven thickness of polyolefin plastomer cast films (Variant: Enhanced Measures)

A

Uneven cast film thickness is caused by uneven die gap or temperature, and needs to be solved from mold precision and temperature uniformity. Targeted preventive measures need to be taken in different production scenarios.

Q

Wrinkles appearing in polyolefin plastomer blown films (Variant: Enhanced Measures)

A

Wrinkles are caused by uneven thickness or unbalanced hauling, and need to be solved from thickness control, hauling, and herringbone plate adjustment. Targeted preventive measures need to be taken in different production scenarios.

Q

Die marks/lines appearing on polyolefin plastomer extruded products (Variant: Enhanced Measures)

A

Die marks are caused by damage to the die inner wall or impurities, and the die condition needs to be regularly cleaned and checked. Targeted preventive measures need to be taken in different production scenarios.

Q

Polyolefin plastomer pipe pressure resistance test unqualified (Variant: Enhanced Measures)

A

Unqualified pressure resistance is caused by insufficient wall thickness, material degradation, or internal defects, and needs to be solved systematically from process and material quality. Targeted preventive measures need to be taken in different production scenarios.

Q

Polyolefin plastomer film blocking/poor opening property (Variant: Enhanced Measures)

A

Film blocking is caused by surface tension and temperature, and needs to be solved by adding anti-blocking agents and controlling winding conditions. Targeted preventive measures need to be taken in different production scenarios.
