Abstract
A kind of anode steel jaw protective cover, mixed by major ingredient and auxiliary material, wherein, major ingredient is made up of bauxitic clay and quartz sand, and the weight of bauxitic clay accounts for the 40-70% of major ingredient gross weight; Described auxiliary material comprises the defoamer of the high temperature adhesive of major ingredient weight 1-20%, the Mierocrystalline cellulose of major ingredient weight 2-10% and major ingredient weight 0.1-5%.In the present invention; the major ingredient such as bauxitic clay, quartz sand the auxiliary material such as high temperature adhesive and Mierocrystalline cellulose auxiliary under; can harden in hot environment; thus anode steel jaw and ionogen, aluminum oxide and other gaseous substance are kept apart by formation protective layer; effectively delay the generation of galvanic corrosion, thus extend the work-ing life of anode steel jaw.
Description
Technical field
The present invention relates to the anode steel jaw that Aluminum Electrolysis Production field is used, specifically a kind of anode steel jaw protective cover.
Background technology
When electrolytic aluminum, used carbon anode needs to use anode steel jaw to be put in electrolyzer by anode block and carries out electrolysis to aluminum oxide.Because anode steel jaw is all generally adopt cast iron casting to form, in the high temperature particular surroundings of electrolyzer, can be corroded gradually, cause its conductivity and intensity all can reduce, not only reduce the work-ing life of anode steel jaw like this, and also adds additional the casting expense of anode steel jaw, result in the rising of production cost.
Summary of the invention
Be corroded in a cell and cause that its electroconductibility is deteriorated, intensity reduces for solving prior art Anodic steel pawl thus affect the problem in work-ing life; the invention provides a kind of anode steel jaw protective cover; by at this protective cover of anode steel jaw external coating; thus the isolation particular surroundings in anode steel jaw and electrolyzer carried out to a certain degree; greatly delay the erosion process of anode steel jaw, extend work-ing life.The present invention is the technical scheme solving the problems of the technologies described above employing: a kind of anode steel jaw protective cover, is mixed by major ingredient and auxiliary material, and wherein, major ingredient is made up of bauxitic clay and quartz sand, and the weight of bauxitic clay accounts for the 40-70% of major ingredient gross weight; Described auxiliary material comprises the defoamer of the high temperature adhesive of major ingredient weight 1-20%, the Mierocrystalline cellulose of major ingredient weight 2-10% and major ingredient weight 0.1-5%.
Also containing the sodium silicate of major ingredient weight 1-20% and the sanitas of major ingredient weight 0.1-5% in described auxiliary material.
Also containing the red mud of 5-10% and the aquamaine stone flour of 3-5% in described major ingredient.
Graphite Powder 99 also containing major ingredient weight 0.5-1% in described auxiliary material.
The preparation method of above-mentioned protective cover is: then each composition first weighed as requested in major ingredient in each composition and auxiliary material mixes; be ground to fineness again and be no more than 100 orders; in use; add a certain amount of water wherein and be painted on after stirring on anode steel jaw; dry in the cool after brushing 2-3 time, and then repeat above-mentioned brushing, dry the brushing that operation one to twice can complete antianode steel pawl.
In the present invention; aluminum oxide in bauxitic clay and the silicon oxide in quartz sand form the structure of similar sial spinel under the high temperature conditions; and auxiliary material is by its bonding rear formation protective layer, Mierocrystalline cellulose at high temperature dewaters after coking and is filled in wherein to prevent corrosive gas and anode steel jaw surface contact from causing the effect such as galvanic corrosion or erosion.
In the present invention, by adding red mud and aquamaine stone flour, formed under aluminum oxide in the micro-oxidation iron contained in red mud and bauxitic clay, the silicon oxide high temperature in quartz sand more stable and fine and close pin, column mullite crystal and be similar to the vitreous state of spinel structure, and aquamaine stone flour for fill space and compensate auxiliary material volume disappearance, and formed packing layer further play isolation action.
Beneficial effect: in the present invention; the major ingredient such as bauxitic clay, quartz sand the auxiliary material such as high temperature adhesive and Mierocrystalline cellulose auxiliary under; can harden in hot environment; thus anode steel jaw and ionogen, aluminum oxide and other gaseous substance are kept apart by formation protective layer; effectively delay the generation of galvanic corrosion, thus extend the work-ing life of anode steel jaw.
