Abstract

The present invention relates to a cement burning curing agent, particularly to cement containing slag. The present invention aims to provide a cement burning curing agent which can not only increase production yield and reduce consumption of the existing cement, but also use various kinds of industrial residue to replace traditional cement raw materials in order to burn cement clinker. The cement burning curing agent uses industrial residue with the granularity of 0.1 to 8MM as a carrier, 9 to 15% of NaCl, 3 to 9% of KClO3, 5 to 10% of KNO3, 1 to 3% of MnO2 and 2 to 5% of active carbon are added, and the cement burning curing agent is formed. The present invention has the advantages that high-quality cement clinker can be all prepared from various kinds of industrial residue, the industrial residue can be effectively and integrally utilized, the waste is changed into valuables, and the environment is improved.

Description

Cement burning ageing agent
Technical field
The present invention relates to cement, furthermore, relate to and contain scoriaceous cement.
Background technology
Traditional manufacture of cement is a raw material with Wingdale and clay, and in order to protect environment, to economize the land resource, people constantly inquire into the approach that utilizes industrial residue producing cement, have also obtained some achievements.No. 85102767 patents " moulded coal heating and producing cement chamotte simultaneously " of Inst. of Environmental Chemistry, Chinese Academy of Sciences application for example, available moulded coal slag is sintered into cement clinker; And for example the 95191233.X patent application of Texas, USA industrial " is used the method and apparatus of slag " in the production of cement clinker, and available slag is produced grog; The patent application (application number is No. 93115608.4, No. 87103601) of production cement such as also useful bone coal, coal gangue.More than these innovation and creation, can use the part producing cement from fag end, but employed waste residue kind is few, consumption is limited.At present, can adopt multiple industrial residue fully is that the method for raw material for producing cement chamotte does not still have report.
Summary of the invention
Purpose of the present invention just provides a kind of cement burning ageing agent, and it not only can be used in existing manufacture of cement producer, plays volume increase, consumption reduction, can also utilize multiple industrial residue to replace traditional cement raw material calcining cement clinker.
The cement burning ageing agent that the contriver provides is to be carrier with the industrial residue, adds following technical grade industrial chemicals: 9%～15%NaCl (weight percent, down together), 3%～9%KClO 3, 5%～10%KNO 3, 1%～3%MnO 2With 2%～5% gac, surplus be carrier.
Used industrial residue granularity is 0.1～8mm; The industrial residue that can be used as carrier comprises: (1) is the plain waste residue of the calcium of main component with CaO, and promptly the tailings of carbide slag, lime production, Wingdale debris, CaO content are abandoned the defibrination throw out, filter mud of sugar refinery etc. of stone, marble processing at 42%～45% low calcium; (2) mainly contain the waste residue of silico-calcium element, i.e. the flyash of yellow phosphorus furnace slag, the heavy slag of ironworks shrend, the dried slag in cupola furnace, slag, thermal power plant etc.; (3) contain the industrial residue of silicon, aluminium, iron, i.e. the gas-making cinder of bone coal, coal gangue, pyrite cinder, synthesis ammonia plant, bauxite slag, oil shale residues etc.
The production method of cement burning ageing agent is: take by weighing the industrial residue that granularity is 0.1～8mm, pour in the mixing tank of band stirring, stirring down, equal and quantitative adds industrial water and KClO 3Saturated solution; Then successively with quantitative NaCl, KNO 3, MnO 2Evenly be sprinkled into abundant the stirring 15 minutes in the mixing tank with gac, make the evenly various raw materials of absorption of carrier, after the check uniformity coefficient is qualified, draws off and bank up, passivation at normal temperatures 48 hours is finished product; Adopt in bulk at last or pack and dispatch from the factory.
Adopt different industrial residues to make carrier, because its composition difference, can obtain the cement burning ageing agent of different varieties, as silicon type, silico-calcium type, sial type, aluminium silicon type, aluminium type, ferro-aluminum type, ferrosilicon type, ferric silicon type, swage and product such as universal.
The application method of cement burning agent is: for the manufacture of cement producer of routine, this product can be replaced the crystal seed, fluorite, fluorine sulphur mixture (fluorite adds gypsum) of grog etc., the centre is directly added to and is fired grog in the raw material; For adopting industrial residue is the manufacture of cement producer of raw material, this product can be prepared burden with other raw material, routinely the technology calcining cement clinker.
At the cement burning ageing agent that the manufacture of cement producer of routine uses this aspect to provide, cement output is increased, cut down the consumption of energy simultaneously, can also improve the label of cement; For adopting industrial residue is the manufacture of cement producer of raw material, can all adopt multiple industrial residue to produce the cement of high index grog, realizes the comprehensive utilization of industrial residue effectively, turns waste into wealth, and improves environment; Method provided by the invention can be used for suitability for industrialized production.
Embodiment
Taking by weighing granularity is the yellow phosphorus furnace slag 710Kg of 0.1～8mm, pours in the mixing tank of band stirring, stirs evenly to add industrial water 50Kg and KClO down 3Saturated solution 50Kg; Then successively with 120KgNaCl, 70KgKNO 3, 20KgMnO 2Evenly be sprinkled into 15 fens kinds of abundant stirring in the mixing tank with the 30Kg gac, make the evenly various raw materials of absorption of carrier, after the check uniformity coefficient is qualified, draws off and bank up, passivation at normal temperatures 48 hours promptly makes about 1 ton of finished product; Packing is dispatched from the factory at last.
