Abstract
The invention discloses one-time sintered chrome green frit dry particles and a preparation method thereof. The frit dry particle preparation raw materials comprise boric acid, borax, feldspar, quartz, dolomite, barium carbonate, non-calcined alumina, zirconium silicate, fluorspar, and chromium oxide. The frit dry particles have an intrinsic chrome green color and good gloss, and are semitransparent. The particles are shiny under light. Because the frit dry particles have the intrinsic chrome green color, a ceramic factory glaze line printing process can be eliminated, glaze line length can be reduced, related staffs can be reduced, modularization collection degree is improved, production efficiency is improved, cost of ceramic enterprises is reduced, and quality controllability is improved. The frit dry particles can be used in a one-time sintering method for preparing microcrystalline tiles. The sintered microcrystalline tile surface glaze has a glistening gentle chrome green color and no pore which is visible to naked eyes. With the one-time sintering process, energy can be saved, emission can be reduced, and consumption can be reduced by approximately 15% than that of twice sintering.
Description
Technical field
The invention belongs to preparing ceramic clinker production technical field, particularly one is once burnt chrome green look frit dry granular and preparation method thereof.
Background technology
Natural stone texture is soft elegant in appearance, elegant style.But large specification lithotome extremely rare, there is certain radioactivity.Devitrified glass is the mixture of a kind of microcrystal being formed through coalescent and crystallization by the glass of certain grain composition and glass.Quality is hard, glittering and translucent.But but devitrified glass is relatively single in design process.And Antique Imitation Tiles can make up this point, thereby meet more human consumer by the design that micro mist cloth, silk screen, cylinder or ink-jet technology can obtain thousands of kinds.But it does not possess space multistory sense and the glittering and translucent property of stone material and devitrified glass.And crystallite brick is a kind of novel product that integrates stone material, glass and Antique Imitation Tiles advantage.
On the surface of biscuit, on cloth, have certain granules to the compound frit powder of joining, the crystallite brick obtaining after twice firing is throws brilliant brick, claims again two degree to burn and throws brilliant brick, secondary burning microcrystal composite board.Throw brilliant brick after polishing, the thickness of clear frit can reach 1～2mm, and the lines that therefore surface prints has more gradation sense, stereoscopic sensation to the more common polished tile of people's artistic effect.But because the low temperature sinter cycle is generally 160min left and right, the high temperature biscuiting time (cycle 50～70min) of burning till is more for the first time wanted slow several times, will make thus production occur inconvenience.First, burn till the once burning that cost is more general and want high; In addition, the adobe that biscuiting line is supplied is greater than the demand of glaze firing line, and unnecessary brick need to manually be removed and unload down, after move back to again glaze firing line, this has not only increased employee's labor capacity and has taken warehouse storage space, has increased handling cost; The more important thing is, biscuiting line can not empty kiln in the idle time, thereby can impel the biscuiting line other products of often changing the line of production, and has increased again employee's labor capacity, and has caused the unstable of kiln, and then reduce conforming product rate when changing the line of production.
Burn if secondary is burnt to change into once, so above problem just can fundamentally be resolved.Crystallite brick once burns, and refers to that wall floor tile green compact are after glazing, stamp, need have certain granules to the compound frit powder of joining at surperficial cloth last layer, then enter the process that kiln burns till.
Because the maximum feature of once-firing is that base glaze reacts maturation together, this just requires base substrate before glaze maturation, gets rid of all volatile components, especially crystal water.General volatile component is just got rid of completely 950 DEG C of left and right, and this just requires cullet of glaze to have high beginning fusing point, reduces or avoids glaze to generate pore.So the special frit of once burning crystallite brick that development is excellent, the excellence rate of guarantee crystallization brick, is the sector technical barrier urgently to be resolved hurrily.
The present invention once burns coloured frit dry granular and itself carries chrome green look, therefore can remove silk screen, cylinder or the ink-jet printing process of ceramics factory's glaze line from, so reduced greatly glaze line length, reduce the employee of related fields, improve production efficiency, promote modularization set degree, for Ceramics Enterprises has reduced cost, and promoted quality controllable degree.Compared to other technologies, frit dry granular of the present invention can be used in the principle of once-firing legal system for crystallite brick, and compared with other once burn special frit, performance is more superior.Once burn the microcrystal composite board that coloured frit dry granular is produced in conjunction with ceramic body, there is high rigidity, corrosion-resistant, resistance to compression, shock resistance, be stained with dirt, the feature such as radiationless less.Coloured frit dry granular of several different colours, the different effect of also can arranging in pairs or groups out, produces colorful crystallite brick.Coloured crystallite brick after polishing has unique artistic effect.

embodiment 7
Green compact apply ground-coat enamel, and consumption is 610 ± 2.5g/m
2, proportion 1.52 ± 0.01; The chrome green look frit dry granular of preparing at ground-coat enamel surface cloth last layer above-described embodiment 1, consumption is 6000 ± 5g/m
2; The adobe of having executed glaze and frit dry granular is fired to 130min in the kiln of 1200 DEG C, obtain chrome green look crystallite brick.
Sintering character: crystallite brick cover-coat enamel is as bright as a sixpence, is sparkling and crystal-clear soft chrome green look, glittering and translucent under the irradiation of light, bright shinny, without the visible pore of naked eyes, pin hole, as shown in Figure 2.
Because this frit is close with the common brick glaze coefficient of expansion modelled after an antique, there is certain base glaze key coat, be combined better with adobe and cover-coat enamel.
The chrome green look frit dry granular that once burns of the present invention passes through lot of experiments, prove out ground reduces boric acid component and increases alumina component, can make frit beginning Melting point elevation to 1050 DEG C left and right, before temperature rises to beginning fusing point, moisture, organism in green compact have volatilized completely.By fluorite and rhombspar, the high temperature viscosity and the slow ground that reduce frit reduce beginning fusing point, are beneficial to high temperature bubble and are gathered into air pocket, increase the buoyancy of bubble floating, thereby bubble is drained as far as possible completely, and throwing is not soil pick-up of free of pinholes afterwards.It is therefore of the present invention that once to burn chrome green look frit dry granular beginning fusing point high, temperature flowing is good, is layered on ceramic board and can makes its base substrate have enough time exhaust at oxidation stage, thereby reach, glaze bubble is few, the object of once-firing, energy-saving and emission-reduction, energy consumption reduces by 15% left and right compared with twice firing;
The chrome green look frit dry granular itself that once burns of the present invention carries chrome green look, therefore can remove the typography of ceramics factory's glaze line from, reduce glaze line length, reduce the employee of related fields, promote modularization set degree, improve production efficiency, for Ceramics Enterprises reduces cost, and promoted quality controllable degree.
