Description

technical field

The invention relates to the technical field of twin-screw extruders, in particular to a device for anti-stirring glass fibers of polyphenylene sulfide composite twin-screw extruders.

Background technique

The polymerization reaction of polyphenylene sulfide composite material is a two-way dynamic chemical equilibrium process. During the synthesis process, it is generally produced through a twin-screw extruder. At present, the twin-screw extruder of polyphenylene sulfide composite material One end is the feed port, and the other end of the twin-screw extruder is the extrusion head. The twin-screw extruder is provided with a vacuum suction port near the extrusion head. The powdery polyphenylene sulfide entering from the feed port The composite material, after being heated, melted and extruded by the twin-screw in the twin-screw extruder, generates high temperature and gradually becomes a molten state. At this time, the organic impurities and oligomers remaining in the polyphenylene sulfide composite material remain at high temperature. Under the condition, sublimation or vaporization will occur, and the twin-screw extruder is drawn out from the vacuum suction port, and the polyphenylene sulfide composite material in the molten state is extruded from the extrusion head, and then cooled and pelletized for spinning;

When the polyphenylene sulfide composite twin-screw extruder is used, the glass fiber may sometimes be disturbed. In order to avoid this situation, the interior of the twin-screw extruder is generally cleaned and maintained, so that the interior of the machine body is relatively perfect. Then the extrusion operation is carried out, but the body and the internal extrusion screw of the existing polyphenylene sulfide composite twin-screw extruder are operated unchanged, and the twin-screw will be located in the processing cavity when it is opened again, and The two extrusion screws are generally arranged symmetrically, which makes it inconvenient to clean and maintain the twin-screws inside the processing chamber, thus affecting the anti-stirring effect in the later stage.
