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
The present invention relates to a kind of dry type impervious material, belong to cement technology field.
Background technology
In traditional technique, leak into ionogen under negative carbon or aluminium liquid easily continues down seepage along refractory brick, cause the insulation construction of electrolyzer to change, the technical indicators such as the heat insulation effect of expection are deteriorated, and work-ing life is shortened.
Summary of the invention
The invention provides a kind of dry type impervious material, in aluminium cell, in impervious material use procedure, its anti-permeability performance against corrosion is determined by material itself.Antiseepage dry materials solving, electrolyzer thermal field problem effectively slows down or stops the change of electrolytic aluminum Bottom heat preservation structure, decreases pot shell distortion damaged simultaneously.Refractory brick gap is weak link, is layed between insulating brick and cathode carbon pieces by antiseepage dry materials, replaces traditional electrolyte groove refractory brick and aluminum oxide bisque, the jolt ramming of dry type high frequency.
For solving above technical problem, the invention provides following technical scheme: a kind of dry type impervious material, carrying out proportioning according to mass ratio as follows: 60 parts, flint clay aggregate, bauxite clinker 6 parts, sodium aluminum fluoride 10 parts, nepheline 14 parts, aluminous cement 10 parts, additive 0.5 part.
This dry type impervious material that the present invention relates to, for a kind of aluminium cell dry type impervious material, be the dry materials mixed by granule fines, be directly layered between insulating brick and cathode carbon pieces, traditional electrolyte groove is replaced to use refractory brick and aluminum oxide bisque, the jolt ramming of dry type high frequency.After sodium aluminum fluoride infiltrates carbon brick parietal suture, the full-bodied glassy nepheline layer of the thick densification of one deck 5 ~ 15mm is formed with dry type impervious material surface reaction, thus stop the continuation infiltration of liquid electrolyte, not reacting below viscous layer, dry materials keeps loose, there are extraordinary globality and volume stability, thus avoid traditional full thickness crack, block groove mode infiltration area, cause melt infiltration---cooling---contraction---vicious cycle gone round and begun again like this in crack.The anti-ionogen osmosis of this product is strong, and high temperature does not sinter, good heat preservation performance, and cost is lower, easy construction, extends point and separates super work-ing life.Be applicable between aluminum electrolytic cell bottom insulating brick and cathode carbon pieces.
Embodiment
A kind of dry type impervious material, carries out proportioning according to mass ratio as follows: 60 parts, flint clay aggregate, bauxite clinker 6 parts, sodium aluminum fluoride 10 parts, nepheline 14 parts, aluminous cement 10 parts, additive 0.5 part.
This dry type impervious material that the present invention relates to, anti-ionogen osmosis is strong, and high temperature does not sinter, good heat preservation performance, and cost is lower, easy construction, extends point and separates super work-ing life.Be applicable between aluminum electrolytic cell bottom insulating brick and cathode carbon pieces.
Following table is product of the present invention and prior art products performance index synopsis:
。
Known by upper table:
1, more effectively solve the gap connection problem of refractory brick between electrolyzer, stop the infiltration of ionogen and aluminium liquid.Than like product Be very effective.
2, product jolt ramming intensity is large, and when carrying charcoal block weight and bundle seam, Impervious Materials is indeformable, and impermeability is strong.
3, this product jolt ramming and brick-building art are simply, and construction conditions, without too many restriction, shortens the construction period.
4, this product is in advanced level at present at home.
Embodiment of the present invention does not form the restriction to the application's scope; within every spirit in the present invention's design and principle, any amendment that one of skill in the art can make, equivalent to replace and improvement etc. all should be included within protection scope of the present invention.
