Pre-baked anode for aluminum electrolysis and preparation method of pre-baked anode
The invention provides a prebaked anode for aluminum electrolysis and a preparation method of the prebaked anode, and belongs to the technical field of electrode material production. The preparation method of the prebaked anode for aluminum electrolysis provided by the invention comprises the following steps: putting a prebaked anode cooked block for aluminum electrolysis into an impregnant for dipping treatment to obtain a dipped cooked block; the impregnant is modified asphalt; carrying out first roasting on the impregnated cooked block to obtain a roasted cooked block; and the roasted cooked blocks are assembled, and the prebaked anode for aluminum electrolysis is obtained. The pre-baked anode cooked block for aluminum electrolysis is subjected to dipping treatment and roasting, so that the weight of the pre-baked anode for aluminum electrolysis can be increased, the volume density of the pre-baked anode can be increased, and the porosity of the pre-baked anode can be reduced, thereby being beneficial to reducing the air permeability and improving the conductivity of the pre-baked anode; in the using process, the device has the advantages of low voltage drop, long pole changing period, basically no carbon residue and high current efficiency.
本发明提供了一种铝电解用预焙阳极及其制备方法，属于电极材料生产技术领域。本发明提供的铝电解用预焙阳极的制备方法，包括以下步骤：将铝电解用预焙阳极熟块置于浸渍剂中进行浸渍处理，得到浸渍熟块；所述浸渍剂为改质沥青；将所述浸渍熟块进行第一焙烧，得到焙烧熟块；将所述焙烧熟块进行组装，得到铝电解用预焙阳极。本发明通过对铝电解用预焙阳极熟块进行浸渍处理以及焙烧，能够使铝电解用预焙阳极增重，提高其体积密度，降低孔隙度，从而有利于降低其空气渗透率，提高导电性，使用过程中具有压降低、换极周期长、基本不会产生炭渣以及电流效率高的优势。
