Description
Technical field
The invention belongs to glass art, and in particular to a kind of devitrified glass, and the invention further relates to the preparation of the devitrified glass
Method.
Background technology
Devitrified glass is a kind of polycrystalline material obtained from by controlling the crystallization of glass.Devitrified glass is new as one kind
Material, its application is also more and more wider.Crystallizing glass sheet material is one kind in the numerous kinds of devitrified glass, and it is a kind of new
High-grade construction decoration material, with intensity is high, wear-resistant, corrosion-resistant, weather resistance, do not absorb water, cleaning it is convenient, "dead"
Physicochemical property and the soft sparkling and crystal-clear, surface compacts of uniform hue, gloss such as harm such as are had no time at the excellent appearance characteristics.Due to crystallite
Glass board material various aspects of performance is superior to lithotome, so being widely used in building inside and outside wall, ground and corridor now
In the top grade fitting-out work such as post.Current product market only has white, grey and ecru, and color is dull.
Raw material used in production crystallizing glass sheet material is essentially all that industrial chemical industry is former in addition to quartz sand at present
Material, has the drawback that：Cost of material is high；Glass continuous melting temperature is high, and Fuel Consumption is big, exacerbates glass metal to kiln
The erosion of refractory material；Simultaneously because industrial chemicals is more, erosion of the glass metal to furnace refractories has also been aggravated.
Iron tailings is a kind of mining wastes of iron ore beneficiating factory discharge, not only land occupation, and contaminant water and air,
Ecological environment is destroyed, it could even be possible to triggering the disastrous accident for causing threat to life and property.Current China to iron tailings still
So lack active and effective comprehensive utilization exploitation.The present invention utilizes iron tailings, turns waste into wealth, and have developed a kind of devitrified glass.
The content of the invention
The purpose that the present invention is is to provide a kind of devitrified glass and preparation method thereof.
The present invention is achieved by the following technical solutions：
A kind of devitrified glass, is to be divided into prepared by raw material by each group of following parts by weight：
The gangue 20-30 quartz sands 20-30 of iron tailings 100
Lithium feldspar 10-20 soda ash 8-12 zinc oxide 4-8
Barium carbonate 4-8 cerium oxide 2-4 cobalt oxides 2-3
Manganese oxide 1-2 alundum (Al2O3) 4-6 cobalt oxides 0.5-1.5
Chromium oxide 1-2 calcium sulfate 1-2.
The preparation method of the devitrified glass, comprises the steps：
（1）Iron tailings is dried, sieve, is well mixed, water content is obtained for 2-3%, granularity is the powdery iron tailings of 30-90 mesh；
（2）Gangue is dried, sieve, is well mixed, water content is obtained for 1.5-3.5%, granularity is the powdery coal of 50-120 mesh
Spoil；
（3）The iron tailings and gangue and other components of powdery are mixed according to the ratio；
（4）Above-mentioned gained mixture is put and melted 1~3 hour at 1400~1450 DEG C of temperature, glass metal is obtained；
（5）Glass metal is flowed into water, water quenching turns into glass particle material；
（6）Glass particle material is put into mould and carries out coring and crystallization forming, in 650 DEG C of coring 0.8~1 hour, then with
5.5 DEG C/min speed is warming up to 1070 DEG C, under elevated pressure conditions crystallization forming, produces devitrified glass.
The base stock of iron tailings is all SiO2、Al2O3、CaO、MgO、K2O、Fe2O3, gangue chemical composition is mainly
SiO2、Al2O3、MgO、K2O、Fe2O3、TiO2 Deng using devitrified glass made from iron tailings and gangue in anti-pressure ability, bending resistance
It is better in ability.
The quartz sand can be vein quartz, quartzite or opal, or they are with the mixture of arbitrary proportion.
Iron oxide contained by iron tailings and gangue, can prepare the raw iron oxide material used during glass, iron tail instead of existing
Other components contained by ore deposit can partly replace the raw materials such as quartz sand, lithium feldspar, soda ash, reduce cost of manufacture, turn waste into wealth；It is pure
Alkali provides sodium oxide molybdena in fusion process, and the main function of sodium oxide molybdena is to reduce the viscosity of glass metal and accelerate to melt, and makes glass
Fusing can smoothly carry out, but consumption cross can at most make deformation of products influence flatness；Barium carbonate can reduce glass metal
Viscosity, be conducive to the fusing of glass, sodium oxide molybdena be less than to the adverse effect of glass properties；Oxygen containing higher amount in iron tailings
Change iron, in 650 DEG C of coring, 1070 DEG C of crystallization formings produce devitrified glass, zinc oxide, oxidation are then suitably added in the feed
Cerium, cobalt oxide, manganese oxide, alundum (Al2O3), cobalt oxide, chromium oxide, calcium sulfate.
The characteristic of Ordinary microcrystalline glass by devitrified glass of the present invention with all being produced with the raw material of industry is contrasted
Experiment, acquired results are as shown in table 1：
Table 1
As can be seen from Table 1, the bending strength of devitrified glass of the present invention, compression strength and impact strength, will
Better than existing Ordinary microcrystalline glass.
The present invention compared with prior art, has the advantages that：
（1）Iron tailings and gangue are used as a kind of devitrified glass raw material, turned waste into wealth, can not only reduce pollution,
Environmental protection, and product physicochemical property can be improved；
（2）Iron tailings and gangue can all replace iron oxide simultaneously, partly instead of quartz sand, lithium feldspar, lime stone, soda ash
Deng convenient source, frit cost can be reduced；
（3）The consumption of conventional fossil and industrial chemicals is reduced, erosion of the glass metal to glass refractories can be mitigated, prolonged
The service life of equipment is grown；
（4）Replaced with iron tailings and coal gangue subculture after the industrial chemicals of part, in the refractory components such as quartz sand, aluminum oxide that tradition is used
Some has been the intrinsic material composition in iron tailings, therefore can be reduced to the fusion temperature of glass from 1550 DEG C
11400~1450 DEG C, and improve glass found speed and melting furnaces efficiency, so as to reduce energy consumption, improve economic benefit；
（5）Devitrified glass of the present invention is a kind of environmental type building and ornament materials, can be widely applied to railway station, machine
The inner-outer wall of the buildings such as field, subway, bank, mall, hospital, museum, library and local-style dwelling houses, ground, step, corridor post, platform
In all kinds of building decoration engineerings such as face.
