高性能膜料ACP7000F的工业生产及性能研究OA北大核心

The industrial scale production for a film-grade PE-HD resin with a commercial brand of ACP7000F was suc-cessfully carried out on a Hostalen ACP industrial installation with a yield of 350 kt·a-1 using a BCE-H200 catalyst.The general performance of the resultant PE-HD resin and its film as well as the catalyst was evaluated by melt flow rate,gel permeability chromatography,and mechanical measurements.The experimental results indicated that the BCE-H200 catalyst had higher activity,more stable hydrogen response,and excellent copolymerization ability.Compared to the con-trol catalyst,the activity of the BCE-H200 catalyst was improved by 87.5%,resulting in a decrease in the hydrogen consumption by 12.5%and in the butene-1 consumption by 13.1%.The obtained PE-HD resin by using the BCE-H200 catalyst shows a large particle size,less fine particles,better mechanical properties,and less gel under a high load.Such performance can meet the production standard.The BCE-H200 catalyst can be used to replace the imported cata-lysts for producing the high-performance film-grade PE-HD resin.In addition,the evaluation on the gel from the control film indicated that the gel was composed of the PE with high molecular weight and low crystallinity.
