摘　　要：采用差示扫描量热仪、红外光谱仪、动态热机械分析仪、万能材料试验机等研究了高熔体流动速率薄壁注塑专用聚丙烯1040TE的结构与性能,并与市场同类产品进行对比。结果表明,2个批次的1040TE各项性能接近,产品质量稳定性好,满足市场应用需求。1040TE含有少量的乙烯,具有较好的抗热氧老化添加剂配方。与市场同类产品相比,1040TE的玻璃化转变温度低3.5~3.9℃,冲击强度高20%以上,雾度和熔融温度较低,抗热氧老化性能较好,熔体流动速率适宜,这些性能对于薄壁注塑的加工和制品性能都是有利的。其他性能与市场同类产品基本相当。Qualitative and quantitative analysis of the mixed alcohol by-product of the Fischer-Tropsch synthesis unit was done by characterization methods of determination of suspended solids content,XRF,ICP,laser particle size distribution analyzer,GC-MS and so on.The removal methods of solid impurities,organic impurities,metal ions,acid components and other harmful substances in mixed alcohols were studied.The results showed that the optimized mixed alcohol treatment plan included three steps:filtration,metal ion removal and acid component removal,and the mixed alcohol treated by this method could meet the feed requirements of the MTP reaction.
