Description
Technical field
The present invention relates to the chemical industry preparation field, specifically is that a kind of electrolytic manganese residues that utilizes is produced air-entrained concrete building block and preparation method thereof, belongs to industrial solid waste reside comprehensive utilization technology.
Technical background
China is the world topmost manganese Metal Production state, and year manganese output reaches more than 90% of Gross World Product, and the acquisition major part of its product is that (main effective constituent is MnCO through sulfuric acid chemical combination rhodochrosite
3) obtain the electrolytic solution manganous sulfate after electrolysis realizes, because MnCO in China manganese ore ore
3Content only in 20%, discharge in the ore by other mineral constituent form with electrolytic manganese residues in the combination reaction process.Generally speaking; Electrolytic manganese residues about 1 ton of electrolytic metal Mn average generation of every production 7-10 ton; Owing to lack the means of effectively utilizing; The electrolytic manganese residues that these water ratio reach about 40% is all stored up in the stockyard; The deslagging of stacking has year by year caused severe contamination to environment, mainly shows as a large amount of ammonia nitrogens of containing in the electrolytic manganese residues, vitriol, heavy metal mn ion etc. near the pollution that atmosphere, water source, soil etc. the slag field cause, and has become the most important reason of restriction China electrolytic manganese industry development.Therefore, the need to be resolved hurrily difficult problem of electrolytic manganese residues recycling.For a long time; Because China is not enough to the attention degree of waste pollution environment in the Industrial processes; This inert material recycling of electrolytic manganese residues difficulty is bigger in addition; The harmlessness disposing of China's electrolytic manganese residues still faces a severe challenge, and its recycling is almost blank, still is in the laboratory study stage about the method for electrolytic manganese residues recycling.Mainly comprise: the starting material of 1) producing as ordinary Portland cement mainly utilize electrolytic manganese residues to belong to the character of silicate material, or electrolytic manganese residues is regarded as industrial gypsum to be used, or to use it for the agent of cement color adaptation as cement setting retarder.2) electrolytic manganese residues is used to produce extraordinary building cementing material.Thisly have problems such as big such as the starting material intractability, that the performance of material property advantage is not obvious with mode, limited its recycling, the recycling approach of China's electrolytic manganese residues is few, and research electrolytic manganese residues recycling is very important problem.
Measure knowledge through the geographic electrolytic manganese residues of China's famous " manganese triangle " being carried out chemical constitution and performance analysis: the radioactivity indication reaches the national regulation requirement, and electrolytic manganese residues belongs to active very low acid slag.See the following form
The radioassay data of electrolytic manganese residues:
| Project | GB6566-2000 | Measured value |
| The internal radiation index | re | ≤1 | 0.2 |
| The external radiation exposure index | r | ≤1 | 0.3 |
The staple of electrolytic manganese residues is measured as follows: (each component content %)
| Sio 2 | Cao | Mgo | Mno | Fe 2o 3 | Al 2o 3 | Na 2o | K 2o | Other | loss | Add up to |
| 32.6 | 11.9 | 1.1 | 4.2 | 12.1 | 5.8 | 0.2 | 0.6 | On a small quantity | 16.8 | 85.3 |
What therefore the existing electrolytic manganese residues trade waste of utilization prepared the high-strength novel autoclave aerated concrete building block of production is fully feasible.
Summary of the invention
The object of the invention is just to above-mentioned problems, provide a kind of technology simple, easy to operate, do not pollute, the electrolytic manganese residues consumption is big, be convenient to formula for a product and Technology that mechanize produces and produce high-strength novel autoclave aerated concrete building block.
The present invention's technical scheme that is adopted of dealing with problems is: a kind of electrolytic manganese residues is produced high-strength air-entrained concrete building block, and it is to be processed by following raw material:
(1), basic raw material: electrolytic manganese residues 48%-58%, silica sand 20-30%, cement 5-10%, unslaked lime 15-25%, described per-cent is weight percentage;
(2), additive: in basic raw material 100%, aluminium powder is that 0.5-1.2 ‰, the water glass of basic raw material is that 1-5%, Supragil GN class washing powder 0.05-0.1 ‰, auxiliary agent total amount are 0.1-0.4%, and described per-cent is weight percentage;
(3), solvent: solvent is a water, and the water material weight ratio of water and basic raw material is 0.6-0.7.
A kind of electrolytic manganese residues is produced the preparation method of high-strength air-entrained concrete building block, may further comprise the steps:
1., electrolytic manganese residues pre-treatment: the calcium lime powder that blending in the electrolytic manganese residues is accounted for total amount 5%-8% stirs, and is for use;
2., fine grinding: will pass through pretreated electrolytic manganese residues and silica sand mixing fine grinding in the said ratio of claim 1, unslaked lime is broken, pulverize, for use;
3., the liquid material is prepared in advance: the water glass of the said ratio of claim 1 is dissolved in dilute in the water that needs to add and makes;
4., spice: will add through aluminium powder, Supragil GN class washing powder and the auxiliary agent described in the good manganese slag of fine grinding, silicon unslaked lime husky and for use, cement, the additive in the said ratio of claim 1 and to have prepared in the liquid material of water glass; Water material weight ratio is 0.6-0.7; All raw material mix to be forced to obtain slip after the high-speed stirring, slip is injected send into the chamber of resting in framed and rested 1-2 hour;
5., vapor cure: treat aluminium powder foaming finish after size cutting base substrate on request; Put into autoclave vapor cure with being about to base substrate, the method for maintenance is: heating up reached 1.25mpa, constant temperature and pressure 6 hours to normal atmosphere in 2.5 hours; Decrease temperature and pressure got product to normal temperature in 2.5 hours again.
Described auxiliary agent is caustic soda, three hydroxy-acetaldehydes and Vilaterm alcohol aldehyde glue, in the auxiliary agent total amount, all accounts for equivalent.
Effective Cao content of said unslaked lime is 70%-80%, and dissolution rate is 8-12 minute, and solvent temperature is 60-80 degree centigrade.
The Sio of said silica sand
2Content is greater than 95%, and silt content is lower than 3%.
Said aluminium powder cover water area greater than 5000cm/g.
Silica sand among the present invention mainly is the silicon content that improves in the manganese slag, gains in strength; The starting material such as cement, lime and additive that use provide the intensity in the early stage and later stage of product; Lime can solidify many metallic elements remaining in the electrolytic manganese residues, decontamination as overbased materials; Can the intensity that chemical reaction increases product take place with many materials in the electrolytic manganese residues and silicon-dioxide etc. again; Especially each component is glued by materials such as cement auxiliary agents more easily in the electrolytic manganese residues after lime activates, and makes its effect be able to greatly bring into play, and the intensity of product is improved; The foam that the aluminium powder foaming produces generates a large amount of spaces in concrete, reduce product density, realizes the light-weight purpose; Water glass is that electrolytic manganese residues is made the active initiator of gelling material and the toughener of silicate concrete intensity; The water glass of adding can make the concrete around the abscess solidify in advance and discharge unnecessary moisture content; Help the raising of product strength, the disadvantageous effects such as excessive slow setting that cause too much because of dihydrate gypsum amount in the electrolytic manganese residues can also be suitably eliminated in the adding of water glass etc.The air-entrained concrete building block unit weight that utilizes present method to produce is low, and intensity is big, and cost is low, is lower than the cost (seeing following table for details) of coal ash autoclaved aerating concrete.
