摘要

在广西石化Unipol气相聚丙烯工艺装置上

通过严格控制原料杂质含量

优化催化剂配比、反应器床层料位、露点温差等各项工艺参数

成功地进行了高速BOPP薄膜专用树脂L5D98的工业化生产。对不同批次样品进行了熔体流动速率、熔流比、等规度、二甲苯可溶物含量、差示扫描量热(DSC)和热分级等分析。结果表明:广西石化生产L5D98产品时工艺控制稳定

各批次样品的各项指标间的平行性较好

产品质量合格且波动较小

能够满足下游客户的加工需要。

Abstract

The BOPP film specialty resin of grade L5D98 were produced industrially by PetroChina Guangxi Petrochemical Company according to controlling impurity content of material

bed level of reactor

dew-point temperature difference of reactor

optimizing ratio of catalyst systems and so on. The properties of different batches L5D98 resin

such as melting flow rate (MFR)

MFR ratio

isotacticity

xylene solubility and crystallinity were analyzed. The results indicated that on one hand

the process were stable in control

on the other hand

the properties were no great differences between different batches L5D98 samples thus productions were able to meet the processing requirement of downstream customers.
