Abstract
The present invention discloses a making method for an underground flue of a magnesium electrolysis workshop. First, a flue groove structure layer for waterproof prestressed concrete is poured underground, the surface of the inner wall of the flue groove structure layer for waterproof prestressed concrete is provided with a layer of cement mortar leveling layer, the surface of the leveling layer is coated with a layer of chlorosulfonation rubber paint waterproof insulated layer, then, an insulated high temperature resistance inner flue is built in the flue groove structure layer, the inner flue is built by firebricks taken as building material and water glass plaster taken as binding material, the top surface of the insulated high temperature resistance inner flue is smeared with a layer of the cement mortar leveling layer and painted with a layer of chlorosulfonation rubber paint waterproof insulated layer, and finally, the top of the inner flue is covered with a layer of prestressed concrete cover plate. The present invention has the advantages of long service life, good climate resistance performance and acid resistance performance, good insulated performance, good heat insulating performance, good waterproof performance and humidity resistance performance. The present invention enables electric conduction chloride in the flue to obtain very reliable insulation isolation, and the present invention can satisfy the production demands better.
Description
Technical field:
The present invention relates to a kind of preparation method of underground flue of magnesium electrolysis workshop, belong to magnesium eletrolysis workshop flue technical field.
Background technology:
In the activities of electrolytic method magnesium smelting, generally all to adopt flue to discharge fume, its flue majority is arranged at underground, directly connects the earth, is connected with the dry chlorine gas (CL about 100 ℃ in flue
2) and the waste gas of hydrogen chloride (HCL), and play ringing in process of production, these gases have stronger corrosion to the flue structure wall, so under the magnesium eletrolysis production status of series voltage height, big electric current, for preventing that flue from not intaking, not making moist, thereby guarantee that it is very important that flue has the good insulation performance performance to the chloride of conduction.And existing flue generally all adopts common masonry of cement mortar brick flue, exists waterproof, protection against the tide, heat insulation and acid resistance is poor, insulating properties are bad, application life is short shortcoming mostly, and therefore existing flue still can not meet the needs of production.
Summary of the invention:
The objective of the invention is: a kind of long service life, weather-proof and acid resistance good is provided, the preparation method that the underground flue of magnesium electrolysis workshop of good insulation performance, thermal insulation and waterproof and dampproof performance is arranged, so that the conduction chloride in the flue has very reliable insulation structure, thereby overcome the deficiencies in the prior art and meet the needs of production.
The present invention is achieved in that it earlier goes out waterproof steel concrete flue groove deck in that underground is cast-in-place, and make one deck cement mortar screeding layer in the inner wall surface of waterproof steel concrete flue groove deck, be coated with one deck chlorosulfonation rubber coating waterproof insulating layer on the surface of cement mortar screeding layer, in flue groove deck, be building materials then and be that adhesives is built out the high temperature resistant inner flue of insulation by laying bricks or stones with sodium silicate mastic with refractory brick, and after the high temperature resistant inner flue end face of insulation is smeared one deck cement mortar screeding layer earlier and is coated with last layer chlorosulfonation rubber coating waterproof insulating layer, cover one deck steel concrete cover plate again at the top of flue groove deck upper oral part inner flue; In order to reach better waterproof effect, built one deck asphalt mortar, bituminous mortar layer at the upper surface of steel concrete cover plate.
Owing to adopted technique scheme; the present invention adopts long service life, weather-proof and acid resistance good, strong adhesion, certain chlorosulfonation rubber coating heat insulation and insulating properties is arranged is the first floor waterproof insulating layer; and build resistant to elevated temperatures refractory brick by laying bricks or stones with sodium silicate mastic and protect the first floor waterproofing course, so just formed good waterproof insulation structure.Therefore, the present invention compared with prior art, the present invention has long service life, weather-proof and acid resistance good and the advantage of good insulation performance, thermal insulation and waterproof and dampproof performance is arranged.The present invention can make the conduction chloride in the flue obtain very reliable insulation isolation, can satisfy well and produce needs.
Description of drawings:
Accompanying drawing 1 is a structural representation of the present invention.
The specific embodiment:
Embodiments of the invention: earlier at the underground flue groove that digs out, in the good groove of excavation, water building waterproofing steel concrete flue groove deck 1 then, make one deck cement mortar screeding layer 2 with 1: 2.5 cement mortar in the inner wall surface of waterproof steel concrete flue groove deck 1, be coated with one deck chlorosulfonation rubber coating waterproof insulating layer 3 on the surface of cement mortar screeding layer 2, the chlorosulfonation rubber coating can directly adopt the finished product of selling on the market, in flue groove deck 1, be building materials then and be that adhesives is built out the high temperature resistant inner flue 4 of insulation by laying bricks or stones with existing sodium silicate mastic with existing refractory brick, and after the end face of the high temperature resistant inner flue 4 of insulation is smeared one deck cement mortar screeding layer earlier and is coated with last layer chlorosulfonation rubber coating waterproof insulating layer 3, top at flue groove deck 1 upper oral part inner flue 4 covers one deck steel concrete cover plate 5 again, make the upper surface of steel concrete cover plate 5 not surpass the indoor terrace absolute altitude, in order to reach better waterproof effect, build the thick 20 millimeters asphalt mortar, bituminous mortar layer 6 of last layer at the upper surface of steel concrete cover plate 5.
