The present invention uses the acidic lithium slag as major raw materials matched with wollastonite, pyrophyllite and kaolin clay through steps such as powder milling, pulping, filter pressing, mud cake making, drying, pulverizing, blank pressing, drying, biscuit firing, glost firing, finished product checking, etc., the biscuit firing temperature is between 1020 and 1060 DEG C, and the glost firing temperature is between 1000 and 1010 DEG C. The present invention uses the acidic lithium slag which is the waste for producing lithium salt by an acid method for replacing partial high-grade raw mineral materials for manufacturing the glazed tile, and has the advantages of waste utilization, low pollution, nuisance abatement, low biscuit firing and glost firing temperature, low energy consumption and low production cost.
Description
The present invention relates to material of construction and manufacture method thereof, particularly a kind of glaze for glazed tile and manufacture method made from acid lithium slag thereof.
In traditional ornamental brick manufacturing technology, have two types substantially, a kind of is the ornamental brick production of ordinary process, and main raw material is quartz, feldspar, high grade kaolinite etc.; Another kind is the ornamental brick production of low temperature fast firing technology, and raw materials used is high grade kaolinite, wollastonite, agalmatolite, talcum etc.No matter making ornamental brick, which kind of traditional technology all to consume a large amount of high-quality raw mineral materialss.Traditional ornamental brick manufacturing technology firing temperature is generally higher.During the ornamental brick of ordinary process was produced, generally between the 1200-1280 degree, temperature of glaze firing was generally between the 1150-1200 degree for the biscuiting temperature; In the low temperature fast firing technology, the biscuiting temperature is generally the 1050-1100 degree, and temperature of glaze firing is generally the 1020-1050 degree.
The object of the present invention is to provide a kind of glaze for glazed tile and manufacture method made from acid lithium slag thereof, utilize acid system to produce the waste of lithium salts-traditional high-quality raw mineral materials of acid lithium slag replacement part and make glaze for glazed tile, can turn waste into wealth, reduce pollution, eliminate public hazards, and biscuiting temperature and temperature of glaze firing are lower, less energy consumption, production cost is low.
The present invention is achieved in that a kind of glaze for glazed tile and production method made from acid lithium slag thereof, with its component of glaze for glazed tile and the content of acid lithium slag manufacturing is:
Acid lithium slag 40-45%
Wollastonite 15-23%
Agalmatolite 10-17%

2. on friction press, be pressed into blue or green base, carry out drying;
3. dried blue or green base is advanced the kiln biscuiting, the biscuiting firing temperature is 1020 ℃-1060 ℃;
4. with after the burned biscuit block-by-block glazing drying, advance Bristol glaze and burn, the glaze firing firing temperature is
1000℃-1010℃；
5. the inspection after construction after the glaze firing is packed.
The selection of the glaze for glazed tile prescription made from acid lithium slag is mainly according to following principle, and the one, according to the physical and chemical performance and the service requirements of ornamental brick; The 2nd, according to the characteristic of various raw materials itself and guarantee the stable of base substrate composition; The 3rd, satisfy the requirement of low temperature fast firing technology; The 4th, make full use of this industrial waste of acid lithium slag, satisfying the amount of allocating into that as far as possible improves acid lithium slag under processing requirement and the assurance product quality premise.
Lithium slag ingredient and ornamental brick are more approaching, but because its plasticity is poor, iron level height, fusing point are low, make the ornamental brick product of excellent property, must arrange in pairs or groups mutually with plurality of raw materials, and the production formula of designing economical rationality is to satisfy the requirement of product and technology.For this reason, experimental selection plastic raw material, non-plastic raw material and flux raw material are as the admixtion of ornamental brick base substrate.Shallow water river kaolin viscosity is good, and the thin and dispersiveness of particle is chosen as plastic raw material by force; Wollastonite itself does not contain gas composition and crystal water, and is dry and to burn till contraction all very little, the coefficient of expansion low and and temperature variation in linear relation, be suitable for burning till fast, non-plastic raw material and flux raw material are elected in experiment as; Low and the non-plastic of the refractoriness of lithium slag own also is a kind of lean property and flux raw material, but since the lithium slag form by multi mineral.For stablizing food ingredient, the adjusting process performance is also introduced raw material formation polycomponent batchings such as agalmatolite in the prescription.
Acid lithium slag is used as the foundation of ornamental brick blank raw material:
1. the chemical ingredients of acid lithium slag and ornamental brick blank are approaching, according to its empirical formula of body of method for expressing of ceramic batch empirical formula are:
I (R
2O+RO): 1.75AL
2O
38.42SiO
2Satisfy Wingdale fine pottery composition range.
2. through the X diffraction analysis, it is the silicate minerals that is fit to Production of Ceramics that the essential mineral of acid lithium slag is formed, and wherein agalmatolite accounts for larger specific gravity again.Agalmatolite is similar with montmorillonite, but it is difficult for absorbing moisture and absorption positively charged ion.It is less that the agalmatolite raw material contains crystal water, and dehydration is slowly always shunk not quite, so be easy for disposing quick Low fire ceramic blank when being heated between the 500-800 degree.
3. contain the Lithium Oxide 98min of 0.3-0.5% in the acid lithium slag, lithium is positioned at first of the basic metal, and atomic radius is 1.56A, and ionic radius is 0.78A, and nucleidic mass is 6.940, and proportion is 0.543, is the lightest metal.Numerous results of study show that the lithiumation thing just can increase substantially the anti-seismic performance and the physical strength of product in ceramic batch a little, reduce sintering temperature, and this production to glaze for glazed tile is very favourable.
Can further be well understood to the present invention by the specific embodiment of the invention given below, but they not limitation of the invention.
