摘要
在环管聚丙烯装置上利用对称加氢生产聚丙烯粉料,控制合适的熔体流动速率(MFR),采用可控流变工艺,通过在造粒机加入液体二叔丁基过氧化物,生产熔融指数达36 g±2 g/10 min的无纺布专用聚丙烯树脂PPHY35。产品灰分≤0.020%,等规度>97.0%,拉伸弹性模量>1 000 MPa。产品性能指标优良,与YS835质量相当,用户使用反馈良好。
Polypropylene powder is produced using symmetric hydrogenation in the ring pipe polypropyl- ene plant, controlling proper melt flow rate, using controlled rheological process, by adding liquid ditert butyl peroxide in granulator, special polypropylene resin PPH -Y35 of melt index of 36 g ± 2 g per 10 minute is produced. Product ash ≤0.020% ,isotacticity 〉97.0% ,stretch elastic mold 〉 1 000 MPa. Product performance indicators are excellent,and the quality of YS835 is quite good,user feedback is good.
