Modified carbon anode and preparation method thereof
The invention relates to a modified carbon anode, and belongs to the technical field of aluminum electrolysis cell anode development. The modified carbon anode comprises a modified carbon block 3 composed of a mixture of ordinary carbon particles and semi graphitic carbon particles, and the graphitic degree of the modified carbon block 3 ranges from 30% to 40%. A production method of the modified carbon anode comprises the steps that the semi graphitic carbon particles and the ordinary carbon particles are evenly mixed with a certain proportion of adhesives and then poured into a vibrating unit to be paved with a certain thickness, and then the modified carbon anode is machined and formed through high-frequency vibration. When the carbon anode is used in an aluminum electrolysis cell, the cycle without electrical conduction for a long time in the aluminum electrolysis cell due to the fact that the anode is replaced can be greatly shortened. The preparation technology is simple and practical, and industrialized application is convenient.
