Dry-type anti-leakage material

Abstract

The invention provides a dry-type anti-leakage material. The dry-type anti-leakage material is prepared by the following components in parts by weight: 60 parts of flint clay aggregate, 6 parts of bauxite clinker, 10 parts of cryolite, 14 parts of nepheline, 10 parts of calcium aluminate cement and 0.5 part of an additive. The dry-type anti-leakage material provided by the invention has the advantages that the effect for preventing electrolyte leakage is strong, no sintering at high-temperature is adopted, the insulating property is good, the cost is low, the construction is convenient, and the service life of an electrolytic cell is prolonged. The dry-type anti-leakage material is suitable for being arranged between an insulating brick and a cathode carbon block at the bottom of an aluminium electrolysis cell.

Description

technical field [0001] The invention relates to a dry anti-seepage material, which belongs to the technical field of cement. Background technique [0002] In the traditional process, the electrolyte or aluminum liquid that leaks under the cathode carbon rod is easy to continue to leak down along the refractory bricks, resulting in changes in the insulation structure of the electrolytic cell, and deterioration of the expected insulation effect and other technical indicators, making the use of Shorter lifespan. Contents of the invention [0003] The invention provides a dry anti-seepage material. In an aluminum electrolytic cell, during the use of the anti-seepage material, its anti-corrosion and anti-seepage properties are determined by the material itself. The anti-seepage dry material effectively slows down or prevents the change of the insulation structure at the bottom of the electrolytic aluminum in solving the problem of the thermal field of the electrolytic cell, an...
