Q
Head pressure fluctuation of linear low-density polyethylene extruder
Q
Haul-off speed mismatch of linear low-density polyethylene extruded products
A
Haul-off speed mismatch needs to be solved by precisely adjusting haul-off parameters and ensuring haul-off stability.

Q
Excessive shrinkage of linear low-density polyethylene extruded products
A
Excessive shrinkage is caused by high crystallinity or high temperature and needs to be solved by controlling temperature and cooling rate.

Q
Poor printability of linear low-density polyethylene film
Q
Longitudinal retraction rate of linear low-density polyethylene pipes exceeding standard
A
Excessive retraction rate is caused by large internal stress or excessive orientation and needs to be solved from temperature control, cooling rate and haul-off speed.

Q
Unstable output/surging in the linear low-density polyethylene extrusion process
A
Unstable output is caused by unstable solid conveying; barrel temperature and the feeding system need to be optimized.

Q
Dimensional fluctuation of linear low-density polyethylene extruded products
A
Dimensional fluctuation is caused by unstable extrusion or haul-off; all process parameters need to be systematically stabilized.
