2239 perguntas
Q
Frequent screen clogging in EAA extrusion
A
Screen clogging is caused by impurities and improper configuration; raw material control and stepped screens are the key
Extrusion & Post EAA extrusion screen clogging gel particle stepped screen automatic screen changing
Q
Wrinkling during winding of EAA extruded film
A
Film wrinkling is caused by tension fluctuations and uneven thickness; automatic tension control and homogenization are the key
Extrusion & Post EAA film winding wrinkle tension control thickness uniformity guide roller parallelism
Q
Insufficient adhesion between EAA and aluminum foil
A
Insufficient adhesion of EAA to aluminum foil is caused by low AA content and the surface condition of the aluminum foil; selecting grades with high AA content is the key
Extrusion & Post EAA aluminum foil adhesion AA content metal adhesion aluminum foil cleaning coating temperature
Q
Unstable feeding in EAA extrusion
A
Unstable feeding is caused by granule characteristics; loss-in-weight feeding and anti-bridging are the core
Extrusion & Post EAA feeding bridging loss-in-weight feeder granulation feeding screw
Q
Poor printing adhesion of EAA film
A
Poor printing adhesion is caused by insufficient surface polarity; corona treatment and special ink are the key
Extrusion & Post EAA film printing adhesion corona treatment special ink surface tension
Q
Rough surface in EAA extrusion
A
Surface roughness is caused by low-temperature extrusion and die defects; raising the temperature and polishing the die are the core countermeasures
Extrusion & Post EAA extrusion rough surface die polishing extrusion temperature melt elasticity
Q
Severe screw wear of EAA extruder
A
Screw wear is caused by filler friction and adhesion; wear-resistant screws and temperature control are the key
Extrusion & Post EAA extrusion screw wear nitrided screw filler friction bimetallic screw
Q
Rough inner wall of EAA extruded pipe
A
Q
Longitudinal streaks in EAA extruded film
A
Longitudinal streaks are caused by die defects and pressure fluctuations; die maintenance and pressure stability are the key
Extrusion & Post EAA film longitudinal streaks die gap melt pressure lip flatness
Q
EAA film blocking, difficult to separate layers
