摘　　要：采用粉末X射线衍射(PXRD)分析法鉴定顺丁橡胶装置溶剂回收系统积垢中的晶体物相。晶体物相鉴定结果为钠铁氟化物(NaFe^(+2)F_3和Na_3Fe^(+3)F_6)。X射线荧光光谱(XRF)测定积垢含氟、钠、铁、碳、锰、氯元素。本试验对顺丁橡胶装置溶剂回收系统积垢技术分析和技改具有指导意义。The phase of crystalline compounds in the sediment incrustation from BR solvent recovery system were identified by powder X-ray diffraction analysis method.The phase were sodium iron fluoride （NaFe＋2F3 and Na3Fe＋3F6）.Fluorine,sodium,iron,carbon,manganese,and chlorine elements were analyzed by XRF.This experiment has guidance significance for the sediment incrustation technical analysis and technical improvements of BR solvent recovery system.
