FHC-7260HDPE抚顺石化---高密度聚乙烯通常使用Ziegler-Natta聚合法制造,其特点是分子链上没有支链,因此分子链排布规整,具有较高的密度。该过程在管式或釜式低压反应器中以乙烯为原料,用氧或有机过氧化物为引发剂引发聚合反应。广泛用于燃气输送、给水、排污、农业灌溉、矿山细颗粒固体输送,以及油田、化工和邮电通讯等领域
High density polyethylene is usually manufactured by ZieglerNatta polymerization method, which is characterized by no branchedchain on the molecular chain, so the molecular chain is regularlyarranged and has high density. In this process, ethylene is used asraw material and oxygen or organic peroxide is used as initiator toinitiate polymerization in a tubular or kettle low-pressurereactor. It is widely used in gas transmission, water supply,sewage discharge, agricultural irrigation, mine fine particle solidtransmission, oil field, chemical industry, post andtelecommunications and other fields
