摘　　要：使用钛系PLE-01催化剂,在Hostalen工艺高密度聚乙烯装置上生产了大中空吹塑专用高密度聚乙烯FHM8255A,并与采用常规铬系催化剂生产的同类专用树脂进行了对比。结果表明:采用钛系PLE-01催化剂生产的FHM8255A的力学性能更好,杂质含量更低,耐老化性能更好,加工成的容积为200 L的双L环密封桶内外表面光滑,单桶质量、壁厚均匀性均满足要求。在耐跌落试验中,该密封桶表现出了优异的耐跌落性能。High density polyethylene(HDPE)FHM8255A for large hollow blow was produced successfully in Hostalen HDPE unit with Ti-based catalyst PLE-01,which was compared with the resin made by the Crbased catalyst.The results show that FHM8255A performs better in mechanical properties,impurities content,and aging resistance.The 200 L large sealed container with double L-rings made by FHM8255A resin has smooth surface,whose weight and wall thickness uniformity meet the requirements.In the drop test,the container performs excellently in drop resistance.
