摘要:
在中国石油辽阳石化公司8万t/a Hoechst淤浆法高密度聚乙烯装置上,采用自主研发的LHPEC-3催化剂,开发出纤维级超高相对分子质量聚乙烯树脂(UHMWPE,牌号为FIUH 4000)。结果表明:在小试聚合评价实验中,催化剂LHPEC-3的活性为3.2×104 g/g,制备的UHMWPE树脂黏均相对分子质量在350×104 g/mol以上;在中试聚合试验中,催化剂LHPEC-3的活性为3.6×104 g/g,产品FIUH 4000黏均相对分子质量在400×104 g/mol以上,堆密度达到0.43 g/cm3,力学性能良好;在工业化试生产中,产品FIUH 4000颗粒分布在110~300 μm,分布指数为0.836,适用于纺丝加工应用。
Abstract:
Fiber-grade ultra-high relative molecular mass polyethylene resin (UHMWPE, grade FIUH 4000) was developed by using the self-developed LHPEC-3 catalyst on the 80 kt/a Hoechst slurry high-density polyethylene plant of Liaoyang Petrochemical Company of PetroChina. The results showed that in the small-scale polymerization evaluation experiment, the activity of the catalyst LHPEC-3 was 3.2×104 g/g, and the viscosity average relative molecular mass of the prepared UHMWPE resin was more than 350×104 g/mol. In the pilot-scale polymerization test, the activity of the catalyst LHPEC-3 was 3.6×104 g/g; the viscosity average relative molecular mass of the product FIUH 4000 was more than 400×104 g/mol, and the heap density reached 0.43 g/cm3 with good mechanical properties. In industrial trial production, the particles of FIUH 4000 were distributed at 110-300 μm,and the distribution index was 0.836, suitable for spinning processing applications.
