Q
POE and PA blend incompatible
A
POE/PA incompatibility requires POE-g-MAH chemical bonding to solve
Extrusion & Post POE/PAincompatiblePOE-g-MAHreactive compatibilizationinterfacial chemical bonding
Q
POE extrusion pipe ovality exceeds standard
A
Ovality is caused by uneven cooling and clamping; annular cooling and uniform haul-off are key
Extrusion & Post POE pipeovalityannular coolingvacuum sizinguniform haul-off
Q
POE extrusion film gel particles
A
Gel particles are caused by insufficient melting; raising temperature and mixing are key
Extrusion & Post POE filmgel particlemelting temperaturemixing sectionhigh molecular weight component
Q
POE extrusion film transverse corrugation
A
Transverse corrugation is caused by haul-off vibration and roller eccentricity; equipment overhaul and stable control are key

Q
POE extrusion screen frequent clogging
A
Screen clogging is caused by impurities and improper configuration; raw material control and stepped screens are key
Extrusion & Post POE extrusionscreen clogginggel particlesstepped screenautomatic screen change
Q
POE extrusion film winding wrinkling
A
Film wrinkling is caused by tension fluctuation and uneven thickness; automatic tension control and uniformization are key
Extrusion & Post POE filmwinding wrinklingtension controlthickness uniformityguide roller parallelism
Q
POE extrusion feeding unstable
A
Feeding instability is caused by pellet characteristics; loss-in-weight feeding and anti-bridging are the core

Q
POE film printing adhesion poor
A
Poor printing adhesion is caused by insufficient surface polarity; corona treatment and special ink are key
Extrusion & Post POE filmprinting adhesioncorona treatmentspecial inksurface tension
Q
POE extrusion film thick edges and thin middle
A
U-shaped thickness is caused by die flow channel and swell difference; coat-hanger die and gap fine adjustment are key
Extrusion & Post POE filmthickness distributioncoat-hanger diegap fine adjustmentedge effect
Q
POE extrusion surface rough
A
Surface roughness is caused by low-temperature extrusion and die defects; raising temperature and polishing the die are core countermeasures
