Proper maintenance is essential to extend the life of the filter screen and maintain production quality.
Inspect filter surface for clogging or residue buildup.
Check for deformation or corrosion signs.
Ensure the filter is securely seated in the spinneret assembly.
Backflushing: Use a reverse flow of solvent or air to remove trapped particles.
Ultrasonic Cleaning: Ideal for deep cleaning fine pores.
Solvent Soaking: Removes sticky polymer residues without damaging the metal.
Daily visual inspection
Weekly ultrasonic cleaning for high-output lines
Monthly comprehensive inspection and replacement if necessary
Clogging: Leads to uneven filament extrusion and reduced quality.
Pore deformation: Causes inconsistent fiber diameters.
Corrosion or wear: Reduces filtration efficiency.
Shut down the extrusion line and remove the filter screen.
Inspect visually for blockages or damage.
Clean or replace the screen as required.
Test the cleaned or new screen under low-pressure conditions before resuming full production.
Use compatible polymers to avoid excessive residue.
Follow recommended cleaning schedules.
Monitor operating temperature and pressure to prevent stress damage.
