5.3 Trioblaid 3: High Wear of Screw and Barrel
Manifestation: Rapid wear of screw and barrel, reduced shear force and mixing capacity; masterbatch dispersibility decreases, equipment maintenance cost increases.
Adhbharan: (1) Raw materials: High-hardness pigments/additives (such as carbon black, titanium dioxide); large particle size. (2) Extrusion parameters: High screw speed, excessive shear force; high extrusion pressure. (3) Uidheam: Screw/barrel material has poor wear resistance.
Fuasglaidhean: (1) Optimize stuthan amh: Select small-particle, low-hardness pigments; crush and sieve raw materials; add lubricants to reduce friction. (2) Adjust parameters: Reduce screw speed and extrusion pressure appropriately. (3) Select high-wear-resistant equipment: Choose Zhuoyue’s HTS PLUS/SUPER/HTE series with bimetallic composite or laser-clad screws/barrels.
5.4 Trioblaid 4: Bubbles in Masterbatch
Manifestation: Bubbles in masterbatch particles, affecting product density and mechanical properties; TPE products have pores and defects.
Adhbharan: (1) Raw materials: High moisture content (especially TPU/TPA); volatile substances in pigments/additives. (2) Extrusion parameters: Low extrusion temperature, incomplete melting; insufficient vacuum exhaust. (3) Premixing: Air mixed into the mixture during premixing.
Fuasglaidhean: (1) Dry raw materials thoroughly: Extend drying time, increase drying temperature. (2) Adjust extrusion parameters: Increase extrusion temperature; improve vacuum exhaust (vacuum degree ≥0.08MPa). (3) Optimize premixing: Reduce mixing speed appropriately to avoid air mixing; use a closed mixer.
5.5 Trioblaid 5: Poor Processing Fluidity, Equipment Blockage
Manifestation: Difficult material conveying and extrusion; unstable extrusion pressure; die head or extrusion cavity blockage.
Adhbharan: (1) Raw materials: High TPE viscosity (TPV/TPC); susbaint àrd pigment (Barrachd air 70%); high moisture content (causing agglomeration). (2) Extrusion parameters: Low temperature, incomplete melting; low screw speed, insufficient conveying capacity. (3) Uidheam: Worn conveying elements; blocked die head.
Fuasglaidhean: (1) Optimize stuthan amh: Reduce pigment content; select low-viscosity TPE; dry raw materials thoroughly. (2) Adjust parameters: Increase extrusion temperature; increase screw speed; replace die head with larger holes. (3) Maintain equipment: Replace worn conveying elements; clean die head and extrusion cavity regularly.
