Q
CEF size changes greatly with temperature
A
Dimensional temperature sensitivity is caused by the large thermal expansion coefficient; adding fillers and annealing are the key
Extrusion & Post CEFdimensional temperature sensitivitythermal expansion coefficientrigid fillerannealing treatment
Q
CEF vacuum section material spitting
A
Material spitting is caused by low melt viscosity; reducing temperature and adding a baffle are the key
Extrusion & Post CEFvacuum section material spittingmelt viscositytemperature reductionvent baffle
Q
CEF surface dense pockmarks
A
Pockmarks are caused by raw material impurities and mold damage; pure raw materials and mold maintenance are the key
Extrusion & Post CEFsurface pockmarkimpurity particlesmold repairraw material purity
Q
CEF extrusion pipe ovality exceeds the standard
A
Ovality is caused by uneven cooling and clamping; annular cooling and uniform haul-off are the key

Q
CEF extrusion film has gel particles
A
Gel particles are caused by insufficient melting; increasing the temperature and mixing are the key

Q
CEF extrusion film has transverse corrugations
A
Transverse corrugations are caused by haul-off vibration and roller eccentricity; equipment overhaul and stable control are the key

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

Q
CEF film printing adhesion poor
A
Poor printing adhesion is caused by insufficient surface polarity; corona treatment and special ink are the key
