| Features : The first stage is SHJ twin screw extruder without die . Through the combination of barrel and screw , the extruder can exert its strong ability to make the thermo sensibility material Iike PVC melting , compounding , disturbing and decentralizjng under the condition of no back pressure . The second stage is SJ single screw extruder . Because of the lower rotate speed , it can complete melting , compounding lengthways and forming strands avoiding over heating. | | | 机组特色: 第一阶为SHJ 系列双螺杆挤出机机筒、螺杆组合设计,出料端未装机头,可在无压下充分发挥塑化、混炼能力强、分布、分散效果好的优势,使PVC 等热敏性材料充分塑化捏合、配混和挤出。 第二阶为SJ 系列单螺杆挤出机.螺杆长径比短,可在低剪切状态下完成塑化和纵向混合及稳定的挤出造粒,避免过热分解。 | |
