Our team of technical engineers carried out the research and development of anti-permeability bricks for electrolyzers in the early stage, focusing on the thermal insulation performance and anti-electrolyte permeation performance of the hinder layer materials. The developed high-quality anti-seepage brick for the barrier layer lining of the aluminum electrolytic cell has better anti-permeability effect, and the new anti-permeability brick has greater compressive strength, more stable structure and better anti-cryolite erosion performance than the traditional dry impermeable material, which can fully meet the high temperature and high pressure environment in the normal operation cycle of the current large-scale electrolytic cell.
