Graphitization thermal insulation material recovery method, regenerated graphite electrode and preparation method
The invention relates to a graphitization thermal insulation material recovery method, a regenerated graphite electrode and a preparation method, the graphitization thermal insulation material recovery method comprises material selection, crushing and mixing, the material selection comprises the following steps: dividing a graphitization thermal insulation waste material with the resistivity of less than or equal to 70 [mu] omega.m into an inner layer material, a middle layer material and an outer layer material; the crushing is as follows: the inner-layer material, the middle-layer material and the outer-layer material are respectively crushed into initial raw materials with 4-6 particle size specifications; the step of blending comprises the step of blending the 4-6 initial raw materials with the same particle size specification according to the ratio of the inner layer material to the middle layer material to the outer layer material being (1-3): (1-2): 1 to obtain a graphitized heat-preservation recycled raw material; the method is used for preparing regenerated graphite products. According to the graphitization heat preservation material recycling method, the graphitization heat preservation recycled raw material is obtained, then the graphitization heat preservation recycled raw material is used for preparing the regenerated graphite electrode, the graphitization heat preservation waste material can be recycled and used for preparing regenerated graphite products, waste is turned into wealth, and the recycling cost is improved.
本发明涉及一种石墨化保温料回收方法、再生石墨电极及制备方法，所述石墨化保温料回收方法包括选材、破碎和掺混，所述选材为：将电阻率≤70μΩ·m的石墨化保温废弃料划分为内层料、中层料和外层料；所述破碎为：将内层料、中层料和外层料分别破碎制成4～6种粒径规格的初始原料；所述掺混为：将所述4～6种同粒径规格的初始原料按内层料：中层料：外层料＝1～3：1～2：1的比例进行掺混，获得石墨化保温回收原料；用于制备再生石墨产品。使用本发明所公开的一种石墨化保温料回收方法获得石墨化保温回收原料，再由石墨化保温回收原料制备再生石墨电极可以将石墨化保温废弃料再利用，用于制备再生石墨产品，变废为宝，提高回收成本。
