In the polymerization reactions industry, the twin-screw extruder serves as a continuous reactor for polymers. It processes reactants, initiators, catalysts, and other components through heating, melting, mixing, reacting, extruding, and devolatilization to achieve the desired polymerization effect.
Using twin-screw extruders for continuous polymerization has distinct advantages over older batch reactor techniques:
1. the polymerization reaction in twin-screw extruders is a continuous process, resulting in time savings and high efficiency.
2. The twin-screw extruder creates an environment for evenly heating and blending the polymer.
3. Efficient heat exchange reduces unexpected reactions, and multi-point feeding increases process flexibility and adaptability.
4. The modular design and precise multi-point temperature control of twin-screw extruders enable real time monitoring of polymer morphology and reaction outcomes.
