Description
Technical field
The present invention relates to a kind of preparation methods of devitrified glass, and in particular to a kind of to prepare R by raw material of red mud2O-CaO-
Al2O3-SiO2-Fe2O3The method of microcrystalline glass in series.
Background technology
Cinder microcrystalline glass is introduced a certain amount of using the industrial residues such as metallurgical slag, tailing and natural minerals as primary raw material
The auxiliary materials such as Nucleating Agent, fluxing agent, through a kind of micro crystal material made of the processes such as dispensing, fusing, molding, annealing, crystallization.
With the quickening of process of industrialization, various slags, tailing are largely discharged and are accumulated, and cause extremely serious environmental problem.And
In national planning, devitrified glass is planned as the emphasis of the strategic development emphasis and environment protection treating of country's comprehensive utilization action.
For devitrified glass majority currently on the market using natural minerals or pure chemicals as primary raw material, production cost is high,
Raw material reserves are relatively low, and cinder microcrystalline glass mainly coordinates a small amount of additive to be produced using various trade wastes,
It is of low cost, raw material rich reserves, while the environmental problem that waste residue is brought can be solved.
Devitrified glass uses slag, has many advantageous conditions because slag contain at adhering to silicate separately
System, composition are close with the ingredient of devitrified glass, it is only necessary to add a small amount of raw mineral materials and industrial chemicals, or no at all
It is additional to produce cinder microcrystalline glass.Gangue, flyash, various mine tailings and metallurgical slag etc. largely stack and with
Sizable yield continues to discharge and stack, and their utilization rate is very low.Therefore slag resource, research and development are rationally utilized
The decorative devitrified glass material of high added value is turned waste into wealth to energy saving, and environment is improved, and is increased economic efficiency and society's effect
Benefit is of great significance.
Red mud, also known as red soil are that the pollution waste residue being discharged in alumina process is being extracted from bauxite, because containing oxidation
Iron is showed red and is gained the name.Average often produces 1 ton of aluminium oxide, incidentally generates 0.8~1.5 ton of red mud.China is as generation
The 4th big alumina producing state of boundary, the red mud discharged every year are 30,000,000 tons or more, and the comprehensive utilization ratio of China's red mud is only at present
4%, accumulative volume of cargo in storage reaches 200,000,000 tons.The most of alumina producers in countries in the world are all to accumulate or be poured into deep-sea by red mud.Red mud is arranged
It is high-volume very big, a large amount of soils and arable land are not only taken up, expend more stockyard construction and maintenance cost, and also contain in red mud
Higher alkali pollutes environment, water source after diafiltration to surrounding water.In addition, the dust that the red mud dried is formed flies everywhere
It raises, destroys ecological environment, cause environmental pollution.If red mud is not only a kind of waste to resource without correct processing,
It is also to environmental ecology even a kind of threat of people's health.So yield and the harm of red mud are reduced to greatest extent,
Realize by all kinds of means, the recycling of big quantity it is extremely urgent.
It is by the main component mass content of composition detection red mud：SiO2(15~20%), CaO (8~12%), Al2O3
(20~30%) and Fe2O3(20~25%) etc..Therefore according to main component Proportionality design rational formula contained by red mud, in conjunction with Shen
It asks someone the technology of independent research, it is proposed that prepare R by raw material of red mud2O-CaO-Al2O3-SiO2-Fe2O3The side of microcrystalline glass in series
Method is hoped in the larger red mud waste of solution accumulating amount, also makes a little contribution to improve environmental problem.
Invention content
The present invention provides one kind preparing R by raw material of red mud2O-CaO-Al2O3-SiO2-Fe2O3The side of microcrystalline glass in series
