Description
Technical field
The invention belongs to environment-friendly function building materials field, be specifically related to a kind of method of utilizing abandoned mine slag to prepare environment-friendly ceramic vitrified tile.
Background technology
Nowadays, the environment protection healthization of architectural pottery has been subject to unprecedented attention.The decoration of people's home room moves towards variation, personalization and fashion-orientation, health, honorableization, material environment friendly, radiationless, easy clean, antibacterial, anti-soil is anticorrosion, the target that the multi-functional people of being of environmental protection pursue, and the continuous utilization of novel material, new technology, new installation, novel process, promoted to build the exploitation of pottery product, towards higher, faster, better future development, be subject to design simultaneously, decorate the impact of theory, its technological design and exploitation will fashions, personalization, hommization, art up, naturalization and multifunction development trend.Tile product has broken through and has only limited in the past scope durable and that decorate, towards the future development of functional diversities.
Technological innovation is the core competitiveness of Building Ceramics Industry.Technical progress and technologic breakthrough, and the improvement of design concept, changing the specification of tile product and the trend of development, and multifunctional and composite type environmental protection exterior wall tile has become one of main direction of development of ceramic wall and floor bricks.In China " 12 " planning, bring forward " Urbanization Construction " strategy; and the construction of " affordable housing ", " guarantee house ", " residential district " will be the most important thing; add the Development of Real Estate Market situation of hyperpyrexia, undoubtedly for larger development space has been expanded in the development of ceramics vitrified brick.Pottery in process of production, normally be take coal gas or Sweet natural gas as fuel, in 30～45min, burns till, and maximum sintering temperature is at 1080～1250 ℃.Ju Qianyuan Soviet Union data, when other condition is identical, 100 ℃ of the every reductions of temperature of combustion, the burnup of unit goods reduces approximately 13%, and fuel cost accounts for the more than 60% of total cost, visible energy consumption is for the importance of Ceramics Enterprises, and the pollution that the topsoil producing while in addition preparing coal gas and the sewage in wet production cause, makes Production of Ceramics frequently face the condition of " highly energy-consuming, high pollution ".New Building Ceramics Industry energy consumption standard proposes higher requirement to building ceramic enterprises, forces architectural pottery manufacturing enterprise, formulates corresponding supplementary measures, allows energy-saving and emission-reduction measure fulfill, and eliminates the backward production facilities, and makes every effort to promote industrial upgrading; Strengthen technical renovation dynamics, the product that development technique content and added value are high.
Existing ceramics vitrified brick is with potter's clay mine tailing, processing waste, potsherd, additive etc., and the ceramic raw material that even uses high-quality having, as main raw material, is fired and formed through 1080～1250 ℃.
Patent discloses " a kind of method of utilizing polished waste material production ceramic tile " (Zheng Shulong, application number: 200410079020.9), polished waste material, high temperature sand, kaolin, low temperature sandstone batch mixing are entered to wet ball grinding in ball mill, cross 250 mesh sieves, after deironing, utilize spray tower to dust in mud standby; Then, utilize ceramic press dry-pressing formed in gained dry powder; Ceramic tile base substrate after moulding is burnt till in ceramic roller kiln to firing temperature 1140C～1200 ℃, firing period 40～75 minutes.Prepare extrudate density and be less than 700kg/m
3, the light building material of strength at break >800N.Although also take waste material as major ingredient, process characteristic and firing mode all belong to the traditional way of highly energy-consuming, high pollution, there is the drawbacks such as firing period is long, energy consumption is high, contaminate environment; Do not belong to same type with material of the present invention.
Patent discloses " utilizing polishing slag to manufacture formula and the method for ceramic tile blank and ornamental brick " (Liang Tongcan, application number: 201210050321.3), take porcelain sand, clay, ceramic polished waste residue is major ingredient, and through wet ball grinding, spraying is dry, moulding, dry, at the temperature of 1080 ℃～1160 ℃, carry out biscuiting, and take to be incubated in 1040 ℃～1060 ℃ temperature provinces, extend the firing time in this region, simultaneously the sintering technology of oxidation reinforced atmosphere and obtain ceramic tile blank.Although the utilization ratio of waste residue is higher, complex technical process, control degree are poor, and still have the drawbacks such as energy consumption is high, contaminate environment.
Patent discloses " a kind of Bian produces the method for Antique Imitation Tiles by low-temperature sintering " (Zhong Xudong, application number: 200610037066.3), the method is to using cullet (42～60%) as main flux raw material, through batching～ball milling～sieve～spray dry～old～compression moulding～be dried～join glaze～ball milling～sieve～old～glaze spraying, in roller kiln, once burn till fast the Antique Imitation Tiles of (firing time 55min, firing temperature <900 ℃).Though widely applied cullet, also have to reduce and burn till energy consumption, the advantage such as reduce production costs.But preparation process is complicated, Production Flow Chart still belongs to traditional ceramics method, consume energy higher, pollute larger.
At present, utilize the secondary resources such as industrial residue or waste material, employing energy consumption is low, pollute little sintering method, optimization technological process and condition, improve microstructure, make ceramics vitrified brick obtain better mechanical property and become main research tendency, for realizing this goal, different waste residues or waste material optimal preparation technology in goods formula, have been introduced, improved to a certain extent the mechanical property of insulating brick, however, the energy consumption that still can not fundamentally solve in traditional ceramics preparation method is high, pollute large, the shortcomings such as surface decoration is single, current pollution treatment is subtracted to haze totally unfavorable.
