Description
Technical field
The present invention relates to the architectural pottery technical field, especially a kind of method of utilizing the many kinds of solids refuse to make Antique Imitation Tiles.
Background technology
Fast development along with social economy and ceramic industry, the ceramic industry waste material is increasing, it is not only exerted heavy pressures on to urban environment, but also has limited the development of urban economy and the Sustainable development of ceramic industry, thus the processing of ceramic industry waste material with utilize extremely important.At present, the processing of China's ceramic industry waste material with utilize degree lower, funds shortage causes a large amount of waste residues to tie up the arable land, and water and air is polluted.
Nearly 20 years high speed development particularly, ceramics is along with the increase of output, the quantity of waste material is more and more, according to incomplete statistics: Foshan Ceramic producing region only, the annual production of various ceramic waste materiaves is above 4,000,000 tons, and the annual production of national ceramic waste material is estimated about 1,000 ten thousand tons, so a large amount of ceramic waste materiaves has not been the soluble problem of simple landfill, and along with the growing and social progress of economy, environment has become the focus that people pay close attention to, the accumulation of ceramic waste material ties up the soil, affects the dust content of local air, and the landfill labor intensive material resources of ceramic waste material, polluted underground water matter also, how turning waste into wealth, the change waste material is resource, has become the task of top priority of science and technology and environmental administration.
At present, it is lower to build the integral level that potler industry solid waste utilizes, and except only needing simply dealt useless mud, useless base recycled by building ceramic enterprises, the utilization ratio of waste product, waste residue is less than 10%.From situation about investigating, the processing present situation of waste product, waste residue is: 1. in the waste product, be used to process slices jigsaw bricks and be cut into the mosaic except sub-fraction polished tile waste product is recovered, the overwhelming majority is taken as refuse and throws away; 2. waste residue except sub-fraction is transported to the construction site uses, mostly please transport countryside or rural area to by cars, and the mode of simple and easy landfill even air storage is processed (account for total amount 97%).A large amount of waste product, waste residues are so processed, not only taken the soil, consumed a large amount of garbage-cleaning expense (about 5～6 yuan/tons of existing Ceramics Enterprises fortune polishing slag expense), and mostly do not adopt in transit closed transport trolley, cause inevitably scatter, the problem such as dust and sand-lime fly upward.
Therefore, government pays much attention to recirculation and the utilization to waste material in the Production of Ceramics, and the height that it is brought up to Viewpoint of Eco materials is studied and utilized, and brings up to the height of whole people's environmental protection and is paid attention to and solve.
The source of waste material and classification:
The ceramic industry waste material mainly refers in the Ceramic Production process, because the waste material that produces in the operations such as shaping, drying, glazing, carrying, roasting and storage, rough classification is as follows usually.
(1) the base substrate waste material mainly refers to before formed waste material of ceramic roasting, comprises green compact waste material, glazing base substrate waste material and biscuiting waste material.
(2) useless mud waste material, it is the wastewater sedimentation thing, the sewage of (except the deep processing operations such as the grinding of polished tile, polishing and edging chamfering) institute's form in the production process of ceramic, the solid waste that sewage forms after purifying treatment, usually contain heavy metal element, what can be divided into poisonous useless glaze and harmful useless glaze by its chemical content.
(3) waste product is the waste material that ceramic generates after roasting, mainly burn till waste product and store and the production process such as carrying in damage cause, be divided into ceramic waste product, Shi matter waste product and porcelain waste product.
(4) ceramic kiln that adopts heavy oil or coal to act as a fuel because unburned carbon loss and the loss of the inadequacy burning for chemistry mechanics reason of heavy oil and coal are higher, has formed the uncombined carbon that does not burn in a large number, very easily pollutes ceramic.Therefore, ceramic ware for daily use adopts the mode of muffle heating to carry out roasting usually.Be to adopt the saggar roasting and obtain the most economical method of muffle type of heating, in addition, still need utilize saggar when extremely other small-sized wall floor tile production enterprise adopts the polychannel tunnel kiln baked article.Because saggar repeatedly bears room temperature, the carrying in the thermal stresses effect of high temperature room temperature and the dress alms bowl process, collision etc. are easy to damage and become the saggar waste residue.
(5) after porcelain brick and thick glazed brick etc. become the polished tile goods of as bright as a sixpence and level and smooth exquisiteness through scraping a series of deep processings such as thicknessing, grinding and polishing and edging chamfering, produce a large amount of brick bits.The grinding and polishing operation usually will be from adobe surface removal 0.5-0.7 millimeter upper layer, sometimes even up to the 1-2 millimeter, produce so 1 square metre of polished tile and will form brick bits about 1.5 kilograms, if take the polishing production line of producing 400000 square metres of polished tile per year as example, the so annual waste residues of polished tiles that produces approximately about 8,400,000 tons.
(6) flyash.At present building ceramic enterprises generally adopts coal to turn gas and prepares fuel, and coal turns and certainly leads to a large amount of flyash in the gas process.Its composition sees the following form.
The chemical ingredients of various flyash
Therefore, for above this situation, the invention provides a kind of formula system and production technology of utilizing in a large number solid waste to make Antique Imitation Tiles, will bring into play great pushing effect to the development of solid waste recycle and ceramic industry.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, provide a kind of and in Antique Imitation Tiles blank raw material prescription, introduce a large amount of solid waste (greater than 40%), process all kinds of solid waste of ceramic industry, stabilization of solid waste chemistry composition and physicochemical property by classification, collection, homogenizing; By using containing solid waste thing Antique Imitation Tiles body recipe and formulating reasonable calcining system of wide firing range, reach the efficient oxidation and decompose and get rid of organic in the base substrate and effectively postpone base substrate pore off-period; Simultaneously by research Antique Imitation Tiles base substrate "dead" whitening agent, solve because using the many kinds of solids refuse to become color stability and the radioactivity problem that exceeds standard.
Purpose of the present invention is achieved by the following technical programs:
In the Antique Imitation Tiles body recipe, introduce the solid waste greater than 40%.Wherein solid waste comprises: useless mud, useless brick, polishing slag, flyash.
