Abstract

The present invention discloses a method for producing composite jade crystal stone in a large specification by using a roller way kiln, which belongs to the technical field of ceramic plate material of building. The method is used for solving the technical problem that the production technologies of building material of nucleated glass and ceramic blank plates are permeated mutually and compounded stably. Therefore, in the present invention, an anchoring agent and blank plates of the jade crystal stone are prepared; the existing dry powder of the molten blocks of the nucleated glass is adopted; the difference among the expansion coefficients of the anchoring agent, the blank plates of the jade crystal stone and the dry powder of the molten blocks of the nucleated glass is smaller than 0.5*10E-6/DEG C; firing curves and cooling curves are designed reasonably, and then the purpose of effectively eliminating air bubbles on a nucleated glass layer can be ensured, so that the finished rate and the excellent rate of final products can be ensured, and stable and continuous production can be realized accordingly. The present invention has the obvious effects that the products have the same decorative effect as a pure nucleated glass plate, but the cost of the products is far lower than the cost of the nucleated glass plate; the composite jade crystal stone can be widely applied to families and decoration of the ground surfaces, inner walls and outer walls of various buildings.

Description

Utilize the compound beautiful spathous production method of the big specification of roller kiln production
Technical field
The present invention relates to architectural pottery sheet material technical field, particularly a kind of compound beautiful spathous production method of the big specification of roller kiln production of utilizing.
Building materials and ornaments originate from Japan with devitrified glass the seventies, its production technique has two kinds of plate method and sintering processs, the plate method is eliminated, and sintering process all is made up of devitrified glass owing to the product entire body, and its technology multistep molding, especially for the second time burn till and use shuttle kiln or tunnel furnace to burn till, firing period is very long, generally surpasses more than 20 hours.The production cost of this method is very high, and the product price is expensive naturally, so devitrified glass is since coming out, its target market has been forced to be locked on the top-grade building thing, can not enter household consumption as polished glazed tile.On the contrary, polished brick in porcelain character is then with short production cycle, production cost is low, the cost/performance ratio height, so it is once appearance, just be subjected to pursuing of family consumer very soon, however, because of material and production technology are limit, all polished glazed tiles are not in beautiful texture, high gloss, the high rigidity of product, aspect such as soil pick-up all can't be compared with devitrified glass at present.
Summary of the invention
How the advantage with devitrified glass and polished brick in porcelain character is blended together, and produce a kind of high-performance of both having had a devitrified glass, and the cheap crystallizing glass sheet material substitute products of cost is the main technical problem to be solved in the present invention.Specifically, the present invention will solve the firm compound technical problem that the production technology of devitrified glass and these two kinds of building material products of polished glazed tile is interpenetrated and realizes devitrified glass and ceramic blank plate.
Technical solution of the present invention is such: a kind of compound beautiful spathous production method of the big specification of roller kiln production of utilizing comprises and adopts explained hereafter, that be made up of following chemical components routinely one or more glass ceramics frit dry powder to be by weight percentage: SiO 255-65, Al 2O 35-10, KNaO 1-7, CaO 8-20, MgO 0-2.5, ZnO 1-10, BaO 0-3, toner 0-2, (one) also comprise the beautiful spar blanket of preparation, and its prescription chemical composition scope is by weight percentage: SiO 255-70, Al 2O 310-20, KNaO 4-9, CaO 2-8, MgO 0-2.5, ZrO 2-10, Fe 2O 30-0.3 its production stage is: prepare burden various mineral by above-mentioned prescription (1); (2) be 250 mesh screen residue 1-6% through wet ball grinding to fineness; (3) at suction pit old 24 hours; (4) spraying drying powder process, powder moisture are 4-10%, and grain composition is: on 20 mesh sieves≤0-2%, 10-15% on 40 mesh sieves, on 60 mesh sieves 〉=50-80%, under 120 mesh sieves≤0-2%; (5) powder is in feed bin old 12-24 hour; (6) powder is through the compression moulding of large-tonnage mouldenpress, and the specification maximum can reach 900 * 1800mm; (7) in roller bed type moisture eliminator drying, drying temperature is 100-180 ℃, 30-80 minute drying cycle, dry back base substrate moisture≤1%; (8) put into roller kiln and burn till blanket, firing period 1-2 hour through 900-1250 ℃; (2) also comprise a kind of wedding agent, its chemical composition scope is by weight percentage: SiO 260-68, Al 2O 310-18, KNaO2-7, CaO 2-10, MgO 0-2, ZnO 1-5, BaO 0-1, ZrO 1-4; Its production stage is: prepare burden various mineral by above-mentioned prescription (1); (2) be 250 mesh screen residue 0.5-3.5% through wet ball grinding to fineness; (3) stirred 12-20 hour in stirred pot, recording its viscosity with the formula viscometer of being coated with is 10-25 second; (3) described blanket, wedding agent, devitrified glass three's the coefficient of expansion is respectively 4~9 * 10E-6/ ℃, 4~8 * 10E-6/ ℃, 5~8 * 10E-6/ ℃, and the three's poor≤0.5 * 10E-6/ ℃; (4) execute one deck wedding agent on described beautiful spar blanket, above-mentioned glass ceramics frit dry powder is evenly distributed on this blanket, its frit dry powder thickness is 3-10mm, putting roller kiln into burns till, firing period is 1-5 hour, and sintering curve is: 15-60 minute, be warmed up to 600-700 ℃ from normal temperature, 30-120 minute, be warmed up to 1000-1250 ℃, 45-200 minute, be cooled to 900-600 ℃, 60-300 minute, be cooled to normal temperature; (5) the kiln discharge work in-process are finished deburring, corase grind, polishing, classification and packing by the automatic polishing line becomes finished product.
In technical scheme of the present invention, (1) selected blanket, wedding agent and devitrified glass three's the coefficient of expansion is respectively 4~9 * 10E-6/ ℃, 4~8 * 10E-6/ ℃, 5-8 * 10E-6/ ℃, require poor≤0.5 * 10E-6/ ℃ of three, stablize compound this technology barrier between glass-ceramic layer and the blanket thereby solved, the phenomenon peeled off etc. such as the distortion of delayed crazing, later stage or glass-ceramic layer can not take place in product.(2) burning till with cooling curve of rationally setting guaranteed that the bubble of glass-ceramic layer can effectively be eliminated, thereby guaranteed the yield rate and the excellent rate of compound beautiful spar product, successfully realizes stable, serialization production.(3) be homogeneity and stability to mud and powder old in process of production in order to guarantee this material and subsequent technique.(4) because blanket intensity 〉=30Mpa can reduce the loss of conveying and cloth.(5) owing to the good combination of devitrified glass and blanket, the folding strength of the finished product can be brought up to 〉=45Mpa;
Compared with prior art, the present invention has following unusual effect:
1, product stable composition and surface almost do not have pore, thereby have folding strength height, yield rate height, excellent rate height and follow the same decorative effect of devitrified glass.
2, utilize roller kiln to produce compound beautiful spar, and firing period is short, can utilizes the alternative expensive glass ceramics frit of part of common material and realize large-scale continuous production, thereby greatly reduce production cost.
