Laboratory twin-screw extruderBy rotating two parallel screws, the material is forcibly conveyed, melted and plasticized, mixed and kneaded, vented and volatilized, and extruded.

　　Laboratory twin-screw extruderTechnical advantages: efficiency, flexibility, and controllability

Strong mixing ability

The high shear force in the twin-screw engagement zone can break aggregates and achieve nanoscale dispersion (such as carbon nanotubes and inorganic fillers). For example, in the preparation of polypropylene/glass fiber composite materials, twin-screw extruders can control the fiber length within 0.2-0.5mm, significantly improving the mechanical properties of the material.

self-cleaning design

The tight meshing structure of the co rotating screw can scrape off residual materials on the inner wall of the barrel, avoiding material degradation. The split barrel design (such as Tianyuan TY-7009) supports quick disassembly and assembly, reducing cleaning time from 2 hours to 10 minutes and minimizing material waste.

Process controllability

Temperature control: Segmented heating (electric heating/oil cooling) and PID algorithm achieve precise temperature control, suitable for processing heat sensitive materials such as PVC.

Speed regulation: The variable frequency drive system supports stepless adjustment of screw speed, optimizes material residence time distribution (RTD), and ensures sufficient reaction extrusion.

Vacuum degassing: The vacuum degree can reach -0.095MPa, effectively removing small molecule impurities and improving product purity.

modular design

Screw components (conveying, compression, shearing, mixing) and barrel sections can be quickly replaced to adapt to different formula tests.
