PVC plastic is a multi-component plastic. Different additives can be added according to different uses. Due to different components, PVC products show different physical and mechanical properties, which can be applied in different occasions. PVC plastic pipe accounts for a large proportion in plasti......
Read MoreIn most extruders, the screw speed is changed by adjusting the motor speed. The drive motor usually rotates at a full speed of about 1750rpm, which is too fast for an extrusion screw. If it rotates at such a fast speed, too much friction heat will be generated, and the uniform and well stirred melt ......
Read MoreAccording to the rotation direction of twin-screw extruder, it can be divided into two types: co rotating extruder and counter rotating extruder. Co rotating twin-screw extruder means that the rotation direction of two screws is the same when they work; The opposite direction extruder refers to that......
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......
Read MoreIn the production process of plastic products, plastic extruder plays the role of extrusion molding, but plastic products need a temperature suitable for plastic production. Therefore, when we produce plastic products, we must first heat up the screw barrel of the plastic extruder.
