2239 perguntas
Q
MP extruded pipe ovality exceeding standard
A
ovality is caused by uneven cooling and clamping; annular cooling and uniform haul-off are key
Extrusion & Post MP pipe ovality annular cooling vacuum sizing uniform haul-off
Q
MP extruded film gel particles
A
gel particles are caused by incomplete melting; raising temperature and mixing are key
Extrusion & Post MP film gel particle melting temperature mixing section high molecular weight component
Q
MP extruded film transverse waviness
A
transverse waviness is caused by haul-off vibration and roller eccentricity; equipment overhaul and stable control are key
Extrusion & Post MP film transverse waviness haul-off vibration cooling roller eccentricity pressure stabilizing device
Q
MP extrusion screen frequent clogging
A
screen clogging is caused by impurities and improper configuration; raw material control and stepped screens are key
Extrusion & Post MP extrusion screen clogging gel particle stepped screen automatic screen change
Q
MP extrusion unstable feeding
A
unstable feeding is caused by pellet characteristics; loss-in-weight feeding and anti-bridging are the core
Extrusion & Post MP feeding bridging loss-in-weight feeder pelletizing feed screw
Q
MP film poor printing adhesion
A
poor printing adhesion is caused by insufficient surface polarity; corona treatment and specific ink are key
Extrusion & Post MP film printing adhesion corona treatment specific ink surface tension
Q
MP extruded film winding wrinkles
A
film wrinkling is caused by tension fluctuation and thickness unevenness; automatic tension control and homogenization are key
Extrusion & Post MP film winding wrinkle tension control thickness uniformity guide roller parallelism
Q
MP extrusion rough surface
A
rough surface is caused by low-temperature extrusion and die defects; raising temperature and polishing the die are the core countermeasures
Extrusion & Post MP extrusion rough surface die polishing extrusion temperature melt elasticity
Q
MP extruder screw severe wear
A
screw wear is caused by filler friction and adhesion; wear-resistant screw and temperature control are key
Extrusion & Post MP extrusion screw wear nitrided screw filler friction bimetallic screw
Q
MP film blocking, difficult delamination
