摘　　要：介绍了国产四氯化钛BL-828在BP工艺生产线型低密度聚乙烯(LLDPE)工业装置上的评价情况。结果表明,n(Ti3+)/n(Ti),n(Cl)/n(Ti总),n(Mg)/n(Ti总)均符合BP工艺的生产技术要求;预聚物的堆密度大于或等于0.28g/cm3,流动性大于-2,平均粒径为270-300μm;流化床的聚合活性为74-76g/g,显示出了明显的高活性。该装置运行平稳,产品达到优等品。This paper introduced the evaluation of domestic titanium tetrachloride BL-828 in line low density polyethylene （LLDPE） plant using of BP process. The results showed that n（Ti^3＋）/n（Fi）, n（Cl）/n（Ti 总） and n（Mg）/ n（Ti 总） all can meet with the productive and technical demand of BP process. The bulk density of pre-polymet is equal or more than 0.28 g/cm^3, flow ability is above -2, the average particle diameter is 270-300μm, and the polymerization active degree of fluidized bed reaches 74-76 g/g, which is obviously beyond that of the imported titanium tetrachloride. The plant operated stably and produced high-class product.
