Abstract

The invention discloses an environment-friendly dry anti-seepage material suitable for an aluminum electrolysis cell. The environment-friendly dry anti-seepage material is prepared from 60-68 parts offlint clay clinker; 15-23 parts of fly ash with particle size less than 0.1 mm; 5-13 parts of coal gangue clinker with particle size of 1-0 mm; 6-10 parts of quartz sand with particle size less than0.088 mm; 3-5 parts of raw clay with particle size less than 0.088 mm and 2-4 parts of an anti-seepage additive with particle size less than 0.074 mm. According to the invention, high-quality coal waste fly ash is used as a main raw material, the raw material source is wide, the quality is stable, the volume of the power plant fly ash is stable after high temperature, the texture is uniform, the heat preservation performance is good, and the price is low; at the same time, the risk of occupying land and harming the environment caused by accumulation of the fly ash is solved, and waste is turned into treasure.

Description

technical field [0001] The invention relates to a technology in the field of aluminum electrolysis, in particular to an environment-friendly dry anti-seepage material suitable for aluminum electrolytic cells. Background technique [0002] As a non-ferrous metal, aluminum plays an important role in the development of the national economy, especially the rapid development of modern science and technology. Human beings are inseparable from the progress of space technology to explore the deep mysteries of the universe. The important progress of aerospace is far from Lightweight design without opening material. Materials such as aluminum and aluminum-magnesium alloys are the best choice for space materials, and aluminum and alloys are also widely used in civil, automotive, decorative materials, solar energy and other industries. [0003] Aluminum smelting technology is mainly produced by electrolysis, which accounts for more than 80% of aluminum output. The electrolyzer is usua...
