The three functional zones of the PVC extruder have different roles.The melting temperature and degradation temperature of PVC are relatively close, and good plasticization is required to prevent degradation of the melt. Therefore, generally according to the work function, with the extruder venting hole as the boundary, it can be divided into two func…

Differences in working principle between co-rotating twin-screw extruder and single-screw extruderTwin-screw extruder is the most common machinery in the modified plastics industry. It is widely used in the polymer processing industry and other production and processing fields. There are many types of twin-screw extruders, which can be divided into two types: meshing …
