Method for preparing large-size isostatic pressing graphite by utilizing photovoltaic single crystal thermal field waste graphite
The invention relates to a method for preparing large-size isostatic pressing graphite by utilizing photovoltaic single crystal thermal field waste graphite, and belongs to the technical field of high-value utilization of waste graphite. According to the method, the isostatic pressing graphite is prepared by doping the photovoltaic single crystal thermal field waste graphite, open pores generated in the roasting process can be reduced, and therefore the number of times of the roasting-dipping technological process can be effectively reduced; the waste graphite thermal field has smaller granularity, and can effectively enter gaps of the petroleum coke and the needle coke in the isostatic pressing forming process as powder; and the photovoltaic single crystal thermal field waste graphite has relatively high density and relatively low ash content, is used for doping preparation of isostatic pressing graphite, and can improve the density of the isostatic pressing graphite and reduce the ash content of the isostatic pressing graphite.
本发明涉及一种利用光伏单晶热场废弃石墨制备大尺寸等静压石墨的方法，属于废弃石墨高值化利用技术领域。本发明利用光伏单晶热场废弃石墨掺杂制备等静压石墨，可以减少在焙烧过程当中产生的开气孔，从而可以有效减少焙烧~浸渍工艺流程的次数；废弃石墨热场具有较小的粒度，在作为粉料进行等静压成型的过程当中可以有效进入石油焦和针状焦的空隙当中；并且光伏单晶热场废弃石墨具有较高的密度和较低的灰分，用于掺杂制备等静压石墨，可以提升等静压石墨的密度，降低等静压石墨的灰分。
