PPR管材料影响MFR变化因素的研究

Study on PPR pipe material the effect of MFR change factors

分析了PP-R(无规共聚聚丙烯)管材料MFR(熔体流动速率)的变化对力学性能的影响,通过双螺杆挤出机研究了PP-R管材料熔融挤出过程中影响MFR变化的因素。结果表明,合适的加工工艺控制和优良的抗氧体系是保证PP-R管材料加工过程中MFR稳定的前提。

The effect of MFR on the mechanical properties of PP-R pipes resin was described. The influence of MFR change during melting extrusion were analyzed in emphasis from twin-screw extruder. The results show that the reasonable processing condition and good antioxidant agent are the base for MFR stable of PP-R pipes resin.
