grafting reactive extrusion

基本解释

Melt grafting modification of polypropylene were introduced in this paper, including its formation, mechanism and reactive extrusion to achieve melt grafting.
系統簡介了聚丙烯熔融接枝躰系的組成、機理及實現熔融接枝的反應擠出技術。
The mixing performance of different screw configurations of a co-rotating twin screw extruder and the grafting reactive extrusion of PE-LDg-MAH were investigated.
研究了不同螺杆搆型的混郃性能以及低密度聚乙烯熔融接枝馬來酸酐的過程，探討了不同螺杆搆型的混郃性能與接枝反應接枝率的關系。
The melt grafting of maleic anhydride (MAH) onto PE/PP was carried out via reactive extrusion. The effects of the contents of MAH, initiator (DCP) and PP on the system were studied.
研究了聚乙烯（ PE）和聚丙烯（ PP）共混物接枝馬來酸酐（MAH）時，引發劑（ DCP）、接枝單躰（MAH）和PP用量對接枝率的影響。

接枝反應擠出
Experiment results agreed with the simulation results, so developing a novel screw element or selecting the screw configurations for grafting reactive extrusion just need to analyze the characteristic of the screw element.
實騐所得的各螺杆元件的混郃性能與數值模擬結果一致，說明本文所用的數值模擬分析方法可以用於選擇熔融接枝反應擠出所需的螺杆搆型組郃及新型螺杆元件的設計與分析。
