Description
Technical field
The invention belongs to building material technical field, be specifically related to a kind of method for preparing colored pottery plate take pyrite tailing as main raw material.
Background technology
Colored pottery plate is take natural clay as main raw material, adds raw mineral materials and a small amount of tinting materials such as quartz, feldspar, and through batching, grinding, mud processed, extrusion moulding, cryodrying and high temperature sintering form.Have environmental protection, radiationless, color and luster is gentle, beautiful decoration, easily cleaning function significantly, the characteristics such as compatibility and good endurance, be a kind of novel curtain wall decoration material.
Pyrite tailing is the waste residue of discharging after pyrite beneficiation.Pyrite tailing is dumped in ground or the gully as waste residue for a long time, serious environment pollution.China's pyrite tailing slag dump storage is huge.Take Sichuan Province of the whole nation one of six large Pyrite Mine Areas as example, its sulfurous iron ore reserves are the first in the nation, and wherein regional (Yibin, two cities, the Luzhou) sulfurous iron ore in south, river accounts for again 97% of the whole province, and prognostic reserves reach 45.2 hundred million tons, and the mine tailing amount accounts for the 60-70% of raw ore.Estimate that the mine tailing that store up on regional ground, south, present river has reached more than 1,000 ten thousand tons.Because mineral processing circuit, appointed condition and the state of the art of each Pyrite Mine Enterprises differs larger, so the chemical component fluctuation of south, river pyrite tailing is larger, and its main chemical constitution is (weight percent) SiO
230 ~ 52%, Al
2O
325 ~ 40%, CaO 0.2 ~ 2.0%, Fe
2O
30.6 ~ 19%, TiO
20.5 ~ 7.0%, SO
30.5 ~ 4.5%, other impurity composition 1 ~ 5%.The essential mineral composition of this pyrite tailing is kaolinite, also contains the dirts such as a small amount of anatase octahedrite, pyrite and calcite.In this mine tailing, thinner part is semisoft clay, and mineralogical composition also has a small amount of nakrite, anatase octahedrite, organic matter, hydromica etc. to reach the pyrite that is not selected except kaolinite, and pyrite content is less.Thicker part forms tailings, the canescence particle, and granularity is difficult to aquation generally at 1～5 mm, belongs to flint clay, is embedded with the pyrite that does not split therebetween.Pyrite tailing is also a kind of potential secondary resource, and wherein contained kaolin composition is the main raw material of preparation pottery plate, rationally, effectively fully utilizes these waste resources, for saving Mineral resources and preserving the ecological environment significant.
At present, at home and abroad there is no the technology of reporting the colored pottery of the preparation plate take pyrite tailing as main raw material.
Summary of the invention
The purpose of this invention is to provide a kind of method for preparing colored pottery plate take pyrite tailing as main raw material, make pyrite tailing obtain comprehensive utilization, both solved the environmental pollution that pyrite tailing brings, can create economic worth again.
Of the present invention is the method that main raw material prepares colored pottery plate with pyrite tailing, and following processing step is arranged:
(1) the pre-homogenizing of pyrite tailing: because the pyrite tailing chemical component fluctuation is larger, should carries out before use pre-homogenizing and process, dwindle the fluctuation range of pyrite tailing chemical composition.
(2) batching: with the pyrite tailing after pre-homogenizing, feldspar, quartz sand, fluidizer (methylcellulose gum or carboxymethyl cellulose), Fe
2O
3Powder is weigh batching as following weight percent: pyrite tailing 40 ~ 75%, feldspar 10 ~ 40%, quartz sand 10 ~ 20%, fluidizer 0.5 ~ 2%, Fe
2O
3Powder 0 ~ 5%.
(3) wet ball grinding, sieve: with each raw material according to after step (1) weighing and mixing, according to quality than raw material: water equals 1:(0.8 ~ 1.2) add moisture, put into the ceramic ball mill grinding to all slips fully by 200 eye mesh screens.
(4) mud is stored, is stirred: in order to improve the performance of ceramic slurry, be stored in the ceramic slurry of step (3) gained in the pond or in container 2 ~ 3 days, and establish agitator and stir, to prevent mud layering or sedimentation.
(5) filter-press dehydration: the resulting ceramic slurry of step (4) is pumped into pressure filter, become mud cake by filter-press dehydration.
(6) pug slightly refines: the mud cake that step (5) is obtained is put into vacuum pugmill and is repeatedly stirred, to improve the plasticity-of pug.
(7) old: will deliver to the pug ageing tower through the pug after step (6), standby after old three days.
(8) pug refining: the pug after old is put into vacuum pugmill again repeatedly stir, with the plasticity-of further raising pug.
(9) extrusion moulding: the pug after step (8) refining is put into the extrusion moulding of extrusion under vacuum machine, and the tile cutter of extruding is become required size.
(10) body drying: be 0.8 ~ 1.5% with brick bat drying to water ratio at 70 ~ 150 ℃ of temperature.
(11) burn till: dried adobe is positioned in kiln burns till, firing temperature is 1100 ~ 1180 ℃.Firing atmosphere is different, and color is different, burns till the colored pottery of redness or yellow colour system plate under oxidizing atmosphere; Burn till the colored pottery of grey colour system plate under reducing atmosphere.
Do not select on a small quantity sulfurous iron ore owing to containing in pyrite tailing in addition, to have sulphur emissions when high temperature burns till out, in order preventing the pollution of the environment, will to improve the ore-dressing technique technology on the one hand, reduce the sulphur content in mine tailing, should carry out flue gas desulfurization on the other hand in actual production.
Compare with existing pottery plate production technology and resource utilization, the present invention has following characteristics and advantages:
(1) the present invention substitutes the raw clay in the preparation of general pottery plate take pyrite tailing as main raw material, can reduce production costs.
(2) the present invention prepared in the technique of colored pottery plate due to the adding of pyrite tailing, and can make its sintering temperature be reduced to 1100 ℃, had effectively reduced the consumption of the energy.
(3) the present invention utilizes industrial residue---and pyrite tailing is main raw material, can realize turning waste into wealth, and the environmental hazard because pyrite tailing is stacked for a long time and oxidation brings is alleviated in energy-conserving and environment-protective effectively.
(4) the colour pottery plate of the present invention's preparation is functional, fire safety, and environmental protection, self-cleaning is good, and color is abundant, and is bright in luster, and color and luster is gentle, and without color spot, decorative effect is good.And can not add tinting material during the colored pottery of preparation yellow or grey colour system plate.
The water-intake rate of the colour pottery plate of the present invention's preparation belongs to quality Shi matter brick preferably 0.7% ~ 6%, and performance meets building industry industry standard " building curtain wall pottery plate " requirement (JG/T324-2011).
