摘要:

主要对合成膜用高密度聚乙烯(PE?HD)进行产品结构分析,确定了合成膜专用树脂6903B的技术指标,并通过调整共聚单体添加量、改变聚合工艺条件,在低压聚合装置上成功生产合成膜用PE?HD产品。经过用户的应用试验,证明PE?HD 6903B能够满足不同厚度合成膜的生产要求。

Abstract:

The article focused on the structure and performance analysis of polyethylene special materials, confirmed the specification of the PE?HD special resin with a commercial grade of 6903B. Through adjusting the addition amounts of comonomers and the processing conditions of polymerization, a PE?HD special resin was successfully produced for the use of compound films. Application experiments confirmed the PE?HD 6903B could meet the requirement of production for compound films with different thicknesses.

Key words: compound film, high density polyethylene, bimodal, molecular weight distribution
