screw extrusion

基本解释

The study on polymer's melting in twin-screw extrusion has been one of difficulties in theory researches, mainly because we couldn't observe the melting phenomena directly.
雙螺杆擠出中的熔融是理論研究的薄弱點之一，其主要原因是在相儅長的一段時間內人們對熔融現象無法作直接的觀察。
Combined the extrudate rheology character, the function relationship among the screw extrusion pressure and the screw working parameter, and the screw geometry dimension were established.
