First of all, the twin-screw extruder of PVC has the principle of the extruder of the single-screw extruder: solid transport, melt pressurization and pumping, mixed stripping and de-evaporation, but it is not just that.
The study of its extrusion process is roughly divided into three links:
1. It is necessary to find out the real situation of the physical state change of two or more polymers and materials during the extrusion process, the mixing shape, the process of structural change, and the relationship between the mixture and function.
2. As a twin-screw extruder, the internal relationship between the reaction process, speed, function and screw configuration and operating conditions during extrusion reaction molding is established as a model to guide reaction molding extrusion.
Twin screw extruder has lasting reliability
Century Extrusion and the world's leading supplier of twin-screw gearboxes have jointly developed high-speed, high-torque gearboxes. In addition to high power and high safety factor, the service life of the main bearing of Century Extrusion Gearbox is up to 50,000 hours.
