摘　　要：在CX工艺装置上采用BCC-100和BCE催化剂在相同工艺控制条件下生产了拉丝料5000S,考察了装置的运行情况和催化剂的性能,利用SEM、GPC、DSC和流变测试等方法表征了树脂的颗粒形态、分子量及其分布和结晶性能。实验结果表明,相比BCE催化剂,BCC-100催化剂生产的树脂粉料颗粒形态为球形或类球形,堆密度高达0.50 g/cm^(3),粒径分布和分子量分布相对较窄,流动休止角相对较小,挥发分含量较低,熔点、熔融焓及结晶度也相对较低。By comparing the wire drawing material 5000S produced by BCC-100 and BCE catalysts in the CX process unit in the same process control conditions,the operation of the device and the performance of the catalysts were investigated.The particle morphology,molecular weight and its distribution,and crystallization properties of the resin were characterized by SEM,GPC,DSC,and rheology tests.The experimental results show that the particle morphology of the resin powder produced by BCC-100 catalyst is spherical or sphere-like,the bulk density is as high as 0.50 g/cm^(3),the particle size distribution and molecular weight distribution are relatively narrow,the flow angle of repose is relatively small,the volatile content is relatively low,and the melting point,melting enthalpy and crystallinity are also relatively low.
