Description
Technical field
The invention belongs to glass art, be specifically related to a kind of blue glass ceramics.The invention still further relates to the preparation method of this blue glass ceramics.
Background technology
Devitrified glass is a kind of polycrystalline material that the crystallization by feed glass obtains.Devitrified glass is as a kind of type material, and its range of application is also more and more wider.Crystallizing glass sheet material is a kind of in the numerous kinds of devitrified glass, it is a kind of novel high-grade building and ornament materials, have the intensity height, resistance to wear, corrosion-resistant, weather resistance, do not absorb water, soft sparkling and crystal-clear, the excellent appearance characteristics such as surface compact is had no time of physicochemical property such as cleaning convenience, "dead" harm and uniform hue, gloss.Because the crystallizing glass sheet material various aspects of performance all is better than lithotome, so be widely used in now in the high-grade fitting-out works such as building inside and outside wall, ground and corridor post.A present produce market adularescent, grey and beige, the color dullness.
Producing the employed raw material of crystallizing glass sheet material at present all is industrial industrial chemicals except quartz sand basically, and the shortcoming of existence is: the raw materials cost height; Glass continuous melting temperature height, fuel consumption are just big, have aggravated the erosion of glass metal to the kiln refractory materials; Because industrial chemicals is more, also increased the weight of the erosion of glass metal simultaneously to furnace refractories.
Iron tailings is a kind of mining wastes of iron ore beneficiating factory discharging, and not only land occupation, and polluted water and atmosphere destroy ecotope, even might cause the disastrous accident that causes threat to life and property.China still lacks active and effective comprehensive utilization exploitation to iron tailings at present.
Blue glass ceramics not only has the characteristic of general devitrified glass, and good visual effect, is applicable to building decoration.
In order to enrich the color of devitrified glass, a kind of blue glass ceramics is provided, overcome the shortcoming of existing production technique, the present invention utilizes iron tailings, turns waste into wealth, and has researched and developed a kind of blue glass ceramics.
Summary of the invention
The present invention is single in order to solve existing devitrified glass color, and the problem that the production technique cost is high provides a kind of blue glass ceramics and preparation method thereof.
The present invention is achieved by the following technical solutions:
A kind of blue glass ceramics is that each component by following weight part is a feedstock production:
Iron tailings 30-55 quartz sand 20-45 lithium feldspar 10-30
Soda ash 2-6 zinc oxide 2-6 barium carbonate 2-6
Manganse Dioxide 0-1 cobalt oxide 0-0.4 SODIUMNITRATE 0-3
The preparation method of described blue glass ceramics comprises the steps:
(1) iron tailings is carried out drying successively, sieves, mixes, obtain the iron tailings of dry powder, water content is 0.5-4%, and granularity is the 40-120 order;
(2) with the iron tailings of dry powder and other components according to described mixed;
(3) above-mentioned gained mixture is placed box high-temperature electric resistance furnace, cell furnace or pot furnace, melted 1～3 hour down for 1480～1520 ℃, obtain the glass metal that viscosity is 10～12Pa.s in temperature;
(4) glass metal is flowed in the water, shrend becomes the glass particle material;
(5) the glass particle material is put into mould and carry out coring and crystallization forming, 650 ℃ of coring 0.7～1 hour, the speed with 4.7 ℃/min was warmed up to 1020～1060 ℃ then, was crystallization forming under the condition of 25Pa at pressure, promptly got black glass ceramic.
Described iron tailings is made up of each component of following weight percent:
SiO
2?25-35％ Al
2O
3?2.5-4.5％ CaO?8-12％
MgO?5-8％ K
2O?0.5-2％ Na
2O?5-2％
Fe
2O
315-20% TiO
2: the 0.1-0.4% surplus is an impurity.
The base stock of iron tailings all is SiO
2, Al
2O
3, CaO, MgO, K
2O, Fe
2O
3, but the source is different, and the content of its each component can be distinguished to some extent, adopts above-mentioned iron tailings, and the devitrified glass that makes is at anti-pressure ability, and on the resistance to bend, effect is better.
Described quartz sand can be vein quartz, quartzite or opal, and perhaps they are with the mixture of arbitrary proportion.
The contained ferric oxide of iron tailings, the raw iron oxide material of using in the time of can replacing having preparation glass now, other contained components of iron tailings can partly replace raw materials such as quartz sand, lithium feldspar, soda ash, reduce cost of manufacture, turn waste into wealth; Soda ash provides sodium oxide in melting process, the main effect of sodium oxide is to reduce the viscosity of glass metal and accelerate fusing, and the fusing of glass can be carried out smoothly, but consumption is crossed and can be made product deformation effect planeness at most; Barium carbonate can reduce the viscosity of glass metal, helps the fusing of glass, to the disadvantageous effect of glass properties less than sodium oxide; The contained ferric oxide of iron tailings 1020～1060 ℃ of crystallization forming, promptly gets blue devitrified glass 650 ℃ of coring, suitably adds Manganse Dioxide, cobalt oxide or SODIUMNITRATE in raw material, makes that the color of product and gloss are purer evenly.
Blue glass ceramics of the present invention and whole characteristics with the common devitrified glass of industrial raw material production are compared test, and the gained result is as shown in table 1:
Table 1
As can be seen from Table 1, the bending strength of blue glass ceramics of the present invention, ultimate compression strength and resistance to impact shock all are better than existing common devitrified glass.
The present invention compared with prior art has following beneficial effect:
(1) this waste of iron tailings is used as a kind of blue glass ceramics raw material, turns waste into wealth, can not only reduce pollution, protection environment, and can improve the product physicochemical property, solve the single problem of devitrified glass color;
(2) iron tailings can all replace ferric oxide simultaneously, and part replaces conventional raw materials such as quartz sand, lithium feldspar, Wingdale, soda ash, can reduce the frit cost more than 25%;
(3) owing to reduced the consumption of conventional mineral and industrial chemicals, can alleviate the erosion of glass metal, prolong the working life of equipment the glass-melting furnace refractory materials;
(4) with behind the iron tailings instead of part industrial chemicals, some has been the intrinsic material composition in the iron tailings in the infusibility components such as the quartz sand that tradition is used, aluminum oxide, therefore the temperature of fusion of glass can be reduced to 1460 ℃ from 1550 ℃, and the speed of founding and the melting furnaces efficient of glass have been improved, thereby reduced energy consumption, improved economic benefit;
(5) blue glass ceramics of the present invention is a kind of environmental type building and ornament materials, can be widely used in all kinds of building decoration engineerings such as interior exterior wall, ground, step, corridor post, table top of buildingss such as railway station, airport, subway, bank, commercial building, hospital, museum, Library and local-style dwelling houses.
