摘要

As an indispensable part of the production of electrolytic fluorine, the quality of the carbon plate determines the running conditions and technical and economic indexes of electrolytic cells. Therefore, improving the service life of carbon plates has become an urgent challenge. Herein, special fluorocarbon plates were successfully prepared via direct heating and asphalt impregnation based on the resistance of the carbon plates, which not only improved their performance index, but also greatly reduced the cost of their production. According to electron microscopy (SEM) observation, the carbon plate prepared by the hot pressing method possessed a more compact internal structure and dislocation phenomenon, which reduced the contact pores between particles, increased the density and reduced the resistivity. The prepared carbon plate exhibited a density of 1.81 g cm ~(?3) , resistivity of 25.8 μΩ m, and service life of 151 days. These results are superior to that of industrial carbon plates with a density of 1.74 g m ~(?3) , resistivity of 36.7 μΩ m, and run time of 90 days, where our fabricated carbon plate exhibited an improvement of 4.5%, 29.7%, and 67.7%, respectively.
