The qualities
1.The first stage is SHJ twin screw extruder with no die.Via the combination of barrel and screw, the extruder can exert its strong ability to make the thermo sensibility content like PVC melting, compounding,dispersing and decentralizing underneath the situation of no back stress
two.The CZPT stage is SJ solitary screw extruder.Since of the reduce rotating velocity, it can complete melting,compounding lengthways and forming srands steadily, avioding in excess of heating.
