Method for preparing prebaked anode by blending recycled graphite of aluminum electrolysis waste cathode carbon block
The invention belongs to the technical field of aluminum electrolysis hazardous waste resource utilization, and particularly relates to a method for preparing a prebaked anode by blending recycled graphite from aluminum electrolysis waste cathode carbon blocks, the contact effect of the recycled graphite and a binder can be remarkably improved through surface modification treatment, and therefore the mixing and kneading quality of the blended prebaked anode is improved; the molten binder is used as a blending carrier of the recovered graphite, so that the dispersion uniformity of the recovered graphite in the organic binder can be improved. The physical and chemical properties of the prebaked anode product prepared by blending the graphite recovered from the aluminum electrolysis waste cathode carbon block meet the related regulations of Prebaked Anode for Aluminum Electrolysis (YS/T 285-2012).
本发明属于铝电解危险废弃物资源化利用技术领域，具体为一种铝电解废阴极炭块回收石墨掺配制备预焙阳极的方法，通过表面改性处理能够显著改善回收石墨与粘结剂的接触效果，从而提高掺配预焙阳极的混捏质量；利用熔融粘结剂作为回收石墨的掺配载体，有利于提高回收石墨在有机粘结剂中的分散均匀程度。本发明利用铝电解废阴极炭块回收石墨掺配制备的预焙阳极产品理化性能满足《铝电解用预焙阳极》(YS/T 285‑2012)相关规定。
