1、In the process of extrusion, the material is transformed from glassy state to molten state. In addition to balancing the heat required for material plasticization and the heat supply, so that the material can complete the ideal plasticization, melt pressing is also a very important control index. ......
Read MoreHere, we briefly introduce the composition and functions of PVC pipe extrusion production line as follows for your reference: I. Raw material mixing: PVC stabilizer, plasticizer, antioxidant and other auxiliary materials are successively added into the high-speed mixer according to proportion and......
Read MoreParallel twin-screw extruder and conical twin-screw extruder can be used to directly produce PVC-U pipe with dry powder. Due to the full engagement of two screws, a closed C-shaped chamber is formed in the twin-screw extruder. The two screws rotate outward in different directions to make the C-shape......
