Dry-type anti-leakage material manufacturing process

Abstract

The invention provides a dry-type anti-leakage material manufacturing process. The dry-type anti-leakage material manufacturing process comprises the following steps: purchasing the following raw materials in parts by mass according to a formula: 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; crushing bauxite clinker, cryolite and nepheline by adopting a jaw crusher and a roll crusher, and then screening by virtue of an electromagnetic vibrating screen, wherein the granularity of the flint clay aggregate is 5-3mm, 3-1mm or 1-0mm; then milling to obtain 200-mesh fine powder by virtue of a Raymond mill; crushing blocky cryolite and nepheline into small particles by adopting the jaw crusher and the roll crusher, and then respectively milling to obtain 180-mesh fine powder and 320-mesh fine powder by virtue of the Raymond mill. The dry-type anti-leakage material manufacturing process has the advantages that electrolyte osmosis resistance is strong, no sintering is caused at high temperature, the heat retaining property is good, the cost is relatively low, the construction is convenient, and the service life of an electrolysis cell is prolonged.

Description

technical field [0001] The invention relates to a dry type anti-seepage material manufacturing process, 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-type anti-seepage material manufacturing process. In an aluminum electrolytic cell, during the use of the anti-seepage material, its anti-corrosion and anti-seepage performance is 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 pro...
