TP series two-stage extruder composed of two bands. The first order is the same twin-screw extruder, and the second-order single-screw extruder. The two stage extruder suitable for the production of SPVC, XLPE and other heat-sensitive materials.
Features: Functional separation, flexible operation
First stage: twin screw extruder
. On the order extruder for high speed twin screw extruder, forced transportation, efficient the plasticization mixing with shear dispersion, inorganic head backpressure backflow, to avoid high shear overheating.
Second stage: single screw extruder
Low-speed operation of large-diameter single screw extruder, a separate temperature control, low speed shear force is small, screw internal cooling to avoid the decomposition of plastic materials, a single screw extruder to ensure the establishment of pressure , stable extrusion.
Applications:
Heat-sensitive polymer processing,
high-capacity exhaust devolatilization processing.
Typical materials:
PVC cable compound,
PVC transparent material,
PVC blood transfusion materials,
LSF or LSZH cable materials,
all kinds of PE cross-linked materials and rubber dehydration processing.
