Description
Technical field
The present invention relates to building materials field, refer more particularly to the manufacture craft of electrolytic manganese slag autoclaved brick.
Background technology
Before the present invention, on market, existing having successfully utilizes electrolytic manganese residues, siliceous material, unslaked lime and appropriate cement to develop the autoclaved brick that intensity reaches 26 MPa, but consider that certain areas do not have siliceous material, for further expanding the use of manganese slag, the present invention determines to utilize Guizhou Province to make electrolytic manganese slag autoclaved brick than more rich mountain sand.
Summary of the invention
The object of this invention is to provide a kind of sand substituted for silicon material that utilizes and make electrolytic manganese slag autoclaved brick, to solve the problem occurring in above-mentioned background technology.
To achieve these goals, the present invention realizes by the following technical solutions:
The manufacture craft of electrolytic manganese slag autoclaved brick, comprises the following steps:
(1) manganese slag pre-treatment: adopt agitating vane is more and whipping force is strong stirrer (as: two transverse axis axle horizontal type stirrers or mortar mixer) the manganese slag of caking is broken up and dispersing and mixing even, wherein, in preprocessing process, manganese slag and water add stirrer simultaneously;
(2) add sand to continue to stir, sand is mixed with finely dispersed manganese slag, standing 9-10h, fully merges both mixtures;
(3) then add cement, water, aluminium powder cream and unslaked lime and stir;
(4) adopt vibration extrusion forming or wet and mould extrusion molding, making autoclaved brick blank;
(5) blank is put into autoclave and carried out high pressure steam press maintenance, the technical parameter in steam pressure process is as follows:
Vapor pressure 1.2 MPa
Line 2 h that heat up
Keep constant temperature 8 h
Continuous cooling 2 h
Then go out still, make electrolytic manganese slag autoclaved brick.
As further illustrating of the present invention program, described cement is 42.5 grades of ordinary portland cements.
As further illustrating of the present invention program, in step (1), in described manganese slag preprocessing process, be also added with the dispersion agent of gross weight 0.2%～0.3%.
In sum, the present invention compares with conventional art and has following beneficial effect:
The present invention is in the area that there is no siliceous material, adopt calcareous material mountain sand to do aggregate, draw materials conveniently, cost is low, be applicable to a large amount of production, and the electrolytic manganese slag autoclaved brick of making meets building material industry standard JC 239-2001 < < flyash brick > > requirement, electrolytic manganese residues volume is more than 60%, the requirement of electrolytic manganese steamed building blocks conformance with standard JC/T862-2008 < < fly ash concrete mini hollow block > > MU15 level, extract detects the requirement that meets standard GB/T/T14848-1993 < < groundwater quality standard > >.
Embodiment
Below in conjunction with the embodiment of the present invention, the technical scheme in the embodiment of the present invention is clearly and completely described, obviously, described embodiment is only the present invention's part embodiment, rather than whole embodiment.Embodiment based in the present invention, those of ordinary skills, not making the every other embodiment obtaining under creative work prerequisite, belong to the scope of protection of the invention.
The manufacture craft of electrolytic manganese slag autoclaved brick, comprises the following steps: first, manganese slag and water are added to two transverse axis axle horizontal type stirrers simultaneously, the manganese slag of caking is broken up and dispersing and mixing even, then, add sand, secondly, add 42.5 grades of ordinary portland cements, water, aluminium powder cream and unslaked lime, so both can make manganese slag stir, can delay the release of ammonia again, and formation be take sand as core, coated outside manganese slag, cement, after hydration reaction, interfacial adhesion is good, the shearing resistance of brick, High anti bending strength, again secondly, adopt vibration extrusion forming or wet and mould extrusion molding, make autoclaved brick blank, because electrolytic manganese residues natural moisture content is high, easily lump again, need to increase and dry, the operations such as fragmentation and screening, this will cause a large amount of energy consumptions to increase, while adopting compression moulding, because brickmaking mixture moisture is too low, caking manganese slag can not be broken up and is uniformly dispersed, and can not make the abundant aquation of cement, unsuitable compression moulding again after moisture is too high, and adopt to wet, mould extrusion molding moisture more suitable (16%～22%), the manganese slag that can make to lump is broken up, can make again each mixing of materials even, and green strength is high, vibration extrusion forming more easily make to lump manganese slag stir loose, the easy uniform mixing of material, finally, blank is put into autoclave and carry out high pressure steam press maintenance, the calcium hydroxide reaction that autoclave can make full use of silicon-dioxide and hydrated cementitious in electrolytic manganese residues forms hydrated calcium silicate gel and improves intensity, and shorten curing cycle, wherein the vapor pressure of autoclave is 1.2 MPa, and continuous warming 2 h, then keeps constant temperature 8 h, after last continuous cooling 2 h, go out still, make electrolytic manganese slag autoclaved brick.
Because electrolytic manganese residues viscosity is excessive, be difficult for dispersed with stirring even, in manganese slag preprocessing process, add the dispersion agent of gross weight 0.2%～0.3%, for improving the processability of manganese slag.
To those skilled in the art, obviously the invention is not restricted to the details of above-mentioned one exemplary embodiment, and in the situation that not deviating from spirit of the present invention or essential characteristic, can realize the present invention with other specific form.Therefore, no matter from which point, all should regard embodiment as exemplary, and be nonrestrictive, scope of the present invention is limited by claims rather than above-mentioned explanation, is therefore intended to include in the present invention dropping on the implication that is equal to important document of claim and all changes in scope.
In addition, be to be understood that, although this specification sheets is described according to embodiment, but not each embodiment only comprises an independently technical scheme, this narrating mode of specification sheets is only for clarity sake, those skilled in the art should make specification sheets as a whole, and the technical scheme in each embodiment also can, through appropriately combined, form other embodiments that it will be appreciated by those skilled in the art that.
